| Calamos Bitcoin Structured Alt Protection ETF - January | Risk Lose Money [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | An investment in the Fund is subject to risks, and you could lose money on your investment in the Fund. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Risk Not Insured [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | Your investment in the Fund is not a deposit in a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). |
| Calamos Bitcoin Structured Alt Protection ETF - January | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the securities held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Capital Protection Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Capital Protection Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 100% of the negative price return (before total fund operating fees and expenses of Spot bitcoin over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses, if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Capital Protection that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Capital Protection will not protect any decreases in the price of Spot bitcoin and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Capital Protection until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents (and therefore the Capital Protection) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while protecting against the entirety of downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the price return of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, the Underlying ETPs' holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors (the managers or organizations in charge of creating and administering a given ETP) do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Costs of Buying and Selling Fund Shares [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The indexes prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs and/or Bitcoin Index. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and therefore the value of the Underlying ETPs and/or Bitcoin Index may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs and/or Bitcoin Index. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the value of the Underlying ETPs and/or Bitcoin Index and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the bitcoin price as reflected by the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause the ARK 21Shares Bitcoin ETF to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better aligns with the ARK 21Shares Bitcoin ETF's investment objective and strategy. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin Structured Alt Protection ETF - January | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and this SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 100% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the approximately 12 month options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 100% protected against downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

| Calamos Bitcoin Structured Alt Protection ETF - January | Liquidity Risk — FLEX Options [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Liquidity Risk — FLEX Options — If and when available, in the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin Structured Alt Protection ETF - January | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Risk — The risk that the securities markets will increase or decrease in value is considered market risk and applies to any security.

| Calamos Bitcoin Structured Alt Protection ETF - January | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin Structured Alt Protection ETF - January | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |

| Risk [Text Block] | • Premium-Discount Risk — Fund Shares may trade above or below their NAV. The market prices of Fund Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Fund Shares on the Exchange.

| Calamos Bitcoin Structured Alt Protection ETF - January | Secondary Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |

| Risk [Text Block] | • U.S. Government Security Risk — Some securities issued by U.S. Government agencies or government-sponsored enterprises are not backed by the full faith and credit of the U.S. and may only be supported by the right of the agency or enterprise to borrow from the U.S. Treasury. There can be no assurance that the U.S. Government will always provide financial support to those agencies or enterprises. |
| Calamos Bitcoin Structured Alt Protection ETF - January | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |
| Calamos Bitcoin Structured Alt Protection ETF - January | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and/or Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). |
| Calamos Bitcoin Structured Alt Protection ETF - April | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the securities held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Capital Protection Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Capital Protection Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 100% of the negative price return (before total fund operating fees and expenses of Spot bitcoin over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses, if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Capital Protection that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Capital Protection will not protect any decreases in the price of Spot bitcoin and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Capital Protection until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents (and therefore the Capital Protection) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while protecting against the entirety of downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the price return of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, the Underlying ETPs' holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors (the managers or organizations in charge of creating and administering a given ETP) do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The indexes prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs and/or Bitcoin Index. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and therefore the value of the Underlying ETPs and/or Bitcoin Index may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs and/or Bitcoin Index. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the value of the Underlying ETPs and/or Bitcoin Index and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges.

The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index.

| Calamos Bitcoin Structured Alt Protection ETF - April | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin Structured Alt Protection ETF - April | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and this SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 100% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the approximately 12 month options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 100% protected against downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

If and when available, in the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

The trading in Listed Options may be less deep and liquid than the market for certain other exchange traded option contracts. In a less liquid market for the Listed Options terminating the Listed Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of Listed Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its Listed Option positions.

| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin Structured Alt Protection ETF - April | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Risk — The risk that the securities markets will increase or decrease in value is considered market risk and applies to any security.

| Calamos Bitcoin Structured Alt Protection ETF - April | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin Structured Alt Protection ETF - April | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Premium-Discount Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Premium-Discount Risk — Fund Shares may trade above or below their NAV. The market prices of Fund Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Fund Shares on the Exchange. The trading price of Fund Shares may deviate significantly from NAV during periods of market volatility. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Secondary Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |
| Calamos Bitcoin Structured Alt Protection ETF - April | U.S. Government Security Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Government Security Risk — Some securities issued by U.S. Government agencies or government-sponsored enterprises are not backed by the full faith and credit of the U.S. and may only be supported by the right of the agency or enterprise to borrow from the U.S. Treasury. There can be no assurance that the U.S. Government will always provide financial support to those agencies or enterprises. |
| Calamos Bitcoin Structured Alt Protection ETF - April | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |
| Calamos Bitcoin Structured Alt Protection ETF - April | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and/or Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Calamos Bitcoin Structured Alt Protection ETF - July | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). |
| Calamos Bitcoin Structured Alt Protection ETF - July | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the securities held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Capital Protection Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Capital Protection Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 100% of the negative price return (before total fund operating fees and expenses of Spot bitcoin over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses, if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Capital Protection that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Capital Protection will not protect any decreases in the price of Spot bitcoin and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Capital Protection until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents (and therefore the Capital Protection) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while protecting against the entirety of downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the price return of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, the Underlying ETPs' holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors (the managers or organizations in charge of creating and administering a given ETP) do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Costs of Buying and Selling Fund Shares [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The indexes prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs and/or Bitcoin Index. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and therefore the value of the Underlying ETPs and/or Bitcoin Index may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs and/or Bitcoin Index. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the value of the Underlying ETPs and/or Bitcoin Index and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the bitcoin price as reflected by the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause the ARK 21Shares Bitcoin ETF to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better aligns with the ARK 21Shares Bitcoin ETF's investment objective and strategy. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin Structured Alt Protection ETF - July | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and this SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 100% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the approximately 12 month options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 100% protected against downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Liquidity Risk — FLEX Options — If and when available, in the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

The trading in Listed Options may be less deep and liquid than the market for certain other exchange traded option contracts. In a less liquid market for the Listed Options terminating the Listed Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of Listed Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its Listed Option positions.

| Calamos Bitcoin Structured Alt Protection ETF - July | Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Risk — The risk that the securities markets will increase or decrease in value is considered market risk and applies to any security.

| Calamos Bitcoin Structured Alt Protection ETF - July | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin Structured Alt Protection ETF - July | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Premium-Discount Risk — Fund Shares may trade above or below their NAV. The market prices of Fund Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Fund Shares on the Exchange.

| Calamos Bitcoin Structured Alt Protection ETF - July | Secondary Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin Structured Alt Protection ETF - July | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |

| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |

In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Calamos Bitcoin Structured Alt Protection ETF - October | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). |
| Calamos Bitcoin Structured Alt Protection ETF - October | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the securities held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Capital Protection Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Capital Protection Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 100% of the negative price return (before total fund operating fees and expenses of Spot bitcoin over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses, if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Capital Protection that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Capital Protection will not protect any decreases in the price of Spot bitcoin and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Capital Protection until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents (and therefore the Capital Protection) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while protecting against the entirety of downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the price return of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, the Underlying ETPs' holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors (the managers or organizations in charge of creating and administering a given ETP) do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Costs of Buying and Selling Fund Shares [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The indexes prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs and/or Bitcoin Index. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and therefore the value of the Underlying ETPs and/or Bitcoin Index may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs and/or Bitcoin Index. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the value of the Underlying ETPs and/or Bitcoin Index and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the bitcoin price as reflected by the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause the ARK 21Shares Bitcoin ETF to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better aligns with the ARK 21Shares Bitcoin ETF's investment objective and strategy. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin Structured Alt Protection ETF - October | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and this SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 100% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the approximately 12 month options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 100% protected against downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

| Calamos Bitcoin Structured Alt Protection ETF - October | Liquidity Risk — FLEX Options [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Liquidity Risk — FLEX Options — If and when available, in the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

| Calamos Bitcoin Structured Alt Protection ETF - October | Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin Structured Alt Protection ETF - October | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Risk — The risk that the securities markets will increase or decrease in value is considered market risk and applies to any security. If there is a general decline in the stock or fixed-income market, it is possible your investment may lose value regardless of the individual results of the companies in which the Fund invests. |
| Calamos Bitcoin Structured Alt Protection ETF - October | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin Structured Alt Protection ETF - October | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Premium-Discount Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Premium-Discount Risk — Fund Shares may trade above or below their NAV. The market prices of Fund Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Fund Shares on the Exchange. The trading price of Fund Shares may deviate significantly from NAV during periods of market volatility. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Secondary Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Government Security Risk — Some securities issued by U.S. Government agencies or government-sponsored enterprises are not backed by the full faith and credit of the U.S. and may only be supported by the right of the agency or enterprise to borrow from the U.S. Treasury. There can be no assurance that the U.S. Government will always provide financial support to those agencies or enterprises. |
| Calamos Bitcoin Structured Alt Protection ETF - October | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |
| Calamos Bitcoin Structured Alt Protection ETF - October | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and/or Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the bitcoin held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Cap Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 90% of the negative price return (before total fund operating fees and expenses over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses (with a maximum loss of 10% of Spot bitcoin over the duration of the Outcome Period), if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Floor that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Floor will not protect any decreases in the price of Spot bitcoin to the extent of such appreciation, and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Floor until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, (and therefore the Floor) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while seeking to protect against the downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the performance of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, Underlying ETP holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the respective Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The Index prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and the value of the Underlying ETPs may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the Underlying ETPs and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets.

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Floor Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Floor Risk — The Fund will be subject to the first 10% of the negative price return of Spot bitcoin, and there can be no guarantee that the Fund will be successful in its strategy to limit the losses in excess of the first 10% experienced by the Underlying ETPs and/or Bitcoin Index during an Outcome Period. The Fund does not provide principal protection or protection of gains and shareholders could experience significant losses including loss of their entire investment. In addition, the Fund's NAV may not change significantly when the share price of the Underlying ETPs and/or Bitcoin Index is materially below the Floor. If the Outcome Period has begun and the Underlying ETP's share price has decreased in value by more than 10%, an investor purchasing or selling shares at that time may not benefit from subsequent gains in the share price of the Underlying ETPs and/or Bitcoin Index until the Floor is reached and exceeded again (i.e., the share price of the Underlying ETPs and/or Bitcoin Index has recovered to a loss of only 10% from the start of the Outcome Period). |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 90% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the one-year options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 90% protected against the Spot bitcoin's downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Liquidity Risk — FLEX Options. If and when available, in the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

The trading in Listed Options may be less deep and liquid than the market for certain other exchange traded option contracts. In a less liquid market for the Listed Options terminating the Listed Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of Listed Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its Listed Option positions.

| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Market Risk [Member] | |

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new put and call options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Premium-Discount Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Premium-Discount Risk — Fund Shares may trade above or below their NAV. The market prices of Fund Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Fund Shares on the Exchange. The trading price of Fund Shares may deviate significantly from NAV during periods of market volatility. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Secondary Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | U.S. Government Security Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Government Security Risk — Some securities issued by U.S. Government agencies or government-sponsored enterprises are not backed by the full faith and credit of the U.S. and may only be supported by the right of the agency or enterprise to borrow from the U.S. Treasury. There can be no assurance that the U.S. Government will always provide financial support to those agencies or enterprises. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - January | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the bitcoin held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Cap Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 90% of the negative price return (before total fund operating fees and expenses over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses (with a maximum loss of 10% of Spot bitcoin over the duration of the Outcome Period), if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Floor that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Floor will not protect any decreases in the price of Spot bitcoin to the extent of such appreciation, and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Floor until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, (and therefore the Floor) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while seeking to protect against the downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the performance of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, Underlying ETP holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Costs of Buying and Selling Fund Shares [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the respective Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The Index prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and the value of the Underlying ETPs may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the Underlying ETPs and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the bitcoin price as reflected by the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause the ARK 21Shares Bitcoin ETF to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better aligns with the ARK 21Shares Bitcoin ETF's investment objective and strategy. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Floor Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Floor Risk — The Fund will be subject to the first 10% of the negative price return of Spot bitcoin, and there can be no guarantee that the Fund will be successful in its strategy to limit the losses in excess of the first 10% experienced by the Underlying ETPs and/or Bitcoin Index during an Outcome Period. The Fund does not provide principal protection or protection of gains and shareholders could experience significant losses including loss of their entire investment. In addition, the Fund's NAV may not change significantly when the share price of the Underlying ETPs and/or Bitcoin Index is materially below the Floor. If the Outcome Period has begun and the Underlying ETP's share price has decreased in value by more than 10%, an investor purchasing or selling shares at that time may not benefit from subsequent gains in the share price of the Underlying ETPs and/or Bitcoin Index until the Floor is reached and exceeded again (i.e., the share price of the Underlying ETPs and/or Bitcoin Index has recovered to a loss of only 10% from the start of the Outcome Period). |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 90% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the one-year options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 90% protected against the Spot bitcoin's downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

The trading in Listed Options may be less deep and liquid than the market for certain other exchange traded option contracts. In a less liquid market for the Listed Options terminating the Listed Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of Listed Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its Listed Option positions.

The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Market Risk [Member] | |

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | New Fund Risk [Member] | |

| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new put and call options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |

| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | U.S. Government Security Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Government Security Risk — Some securities issued by U.S. Government agencies or government-sponsored enterprises are not backed by the full faith and credit of the U.S. and may only be supported by the right of the agency or enterprise to borrow from the U.S. Treasury. There can be no assurance that the U.S. Government will always provide financial support to those agencies or enterprises. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - April | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the bitcoin held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Cap Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 90% of the negative price return (before total fund operating fees and expenses over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses (with a maximum loss of 10% of Spot bitcoin over the duration of the Outcome Period), if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Floor that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Floor will not protect any decreases in the price of Spot bitcoin to the extent of such appreciation, and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Floor until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, (and therefore the Floor) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while seeking to protect against the downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the performance of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, Underlying ETP holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Costs of Buying and Selling Fund Shares [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the respective Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The Index prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and the value of the Underlying ETPs may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the Underlying ETPs and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the bitcoin price as reflected by the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause the ARK 21Shares Bitcoin ETF to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better aligns with the ARK 21Shares Bitcoin ETF's investment objective and strategy. |

| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Floor Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Floor Risk — The Fund will be subject to the first 10% of the negative price return of Spot bitcoin, and there can be no guarantee that the Fund will be successful in its strategy to limit the losses in excess of the first 10% experienced by the Underlying ETPs and/or Bitcoin Index during an Outcome Period. The Fund does not provide principal protection or protection of gains and shareholders could experience significant losses including loss of their entire investment. In addition, the Fund's NAV may not change significantly when the share price of the Underlying ETPs and/or Bitcoin Index is materially below the Floor. If the Outcome Period has begun and the Underlying ETP's share price has decreased in value by more than 10%, an investor purchasing or selling shares at that time may not benefit from subsequent gains in the share price of the Underlying ETPs and/or Bitcoin Index until the Floor is reached and exceeded again (i.e., the share price of the Underlying ETPs and/or Bitcoin Index has recovered to a loss of only 10% from the start of the Outcome Period). |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 90% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the one-year options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 90% protected against the Spot bitcoin's downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Liquidity Risk — FLEX Options [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Liquidity Risk — FLEX Options — If and when available, in the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

The trading in Listed Options may be less deep and liquid than the market for certain other exchange traded option contracts. In a less liquid market for the Listed Options terminating the Listed Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of Listed Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its Listed Option positions.

| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Risk — The risk that the securities markets will increase or decrease in value is considered market risk and applies to any security.

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new put and call options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Premium-Discount Risk [Member] | |

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Secondary Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - July | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |

| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the bitcoin held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Cap Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 90% of the negative price return (before total fund operating fees and expenses over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses (with a maximum loss of 10% of Spot bitcoin over the duration of the Outcome Period), if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Floor that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Floor will not protect any decreases in the price of Spot bitcoin to the extent of such appreciation, and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Floor until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, (and therefore the Floor) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while seeking to protect against the downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the performance of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, Underlying ETP holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Costs of Buying and Selling Fund Shares [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the respective Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The Index prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and the value of the Underlying ETPs may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the Underlying ETPs and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the bitcoin price as reflected by the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause the ARK 21Shares Bitcoin ETF to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better aligns with the ARK 21Shares Bitcoin ETF's investment objective and strategy. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Floor Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Floor Risk — The Fund will be subject to the first 10% of the negative price return of Spot bitcoin, and there can be no guarantee that the Fund will be successful in its strategy to limit the losses in excess of the first 10% experienced by the Underlying ETPs and/or Bitcoin Index during an Outcome Period. The Fund does not provide principal protection or protection of gains and shareholders could experience significant losses including loss of their entire investment. In addition, the Fund's NAV may not change significantly when the share price of the Underlying ETPs and/or Bitcoin Index is materially below the Floor. If the Outcome Period has begun and the Underlying ETP's share price has decreased in value by more than 10%, an investor purchasing or selling shares at that time may not benefit from subsequent gains in the share price of the Underlying ETPs and/or Bitcoin Index until the Floor is reached and exceeded again (i.e., the share price of the Underlying ETPs and/or Bitcoin Index has recovered to a loss of only 10% from the start of the Outcome Period). |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 90% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the one-year options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 90% protected against the Spot bitcoin's downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Liquidity Risk — FLEX Options [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Liquidity Risk — FLEX Options. If and when available, in the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Risk — The risk that the securities markets will increase or decrease in value is considered market risk and applies to any security.

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new put and call options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |

| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Secondary Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |

| Risk [Text Block] | • U.S. Government Security Risk — Some securities issued by U.S. Government agencies or government-sponsored enterprises are not backed by the full faith and credit of the U.S. and may only be supported by the right of the agency or enterprise to borrow from the U.S. Treasury. There can be no assurance that the U.S. Government will always provide financial support to those agencies or enterprises. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |
| Calamos Bitcoin 90 Series Structured Alt Protection ETF - October | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act.

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the securities held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Cap Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 80% of the negative price return of Spot bitcoin (before total fund operating fees and expenses over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses (with a maximum loss of 20% of Spot bitcoin over the duration of the Outcome Period), if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Floor that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Floor will not protect any decreases in the price of Spot bitcoin to the extent of such appreciation, and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Floor until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents (and therefore the Floor) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while seeking to protect against the downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the price return of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, the Underlying ETPs' holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors (the managers or organizations in charge of creating and administering a given ETP) do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The Index prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs and/or Bitcoin Index. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and therefore the value of the Underlying ETPs and/or Bitcoin Index may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs' shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs and/or Bitcoin Index. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the Underlying ETPs and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets.

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Floor Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Floor Risk — The Fund will be subject to the first 20% of the negative price return of Spot bitcoin, and there can be no guarantee that the Fund will be successful in its strategy to limit the losses in excess of the first 20% experienced by the Underlying ETPs and/or Bitcoin Index during an Outcome Period. The Fund does not provide principal protection or protection of gains and shareholders could experience significant losses including loss of their entire investment. In addition, the Fund's NAV may not change significantly when the share price of the Underlying ETPs and/or Bitcoin Index is materially below the Floor. If the Outcome Period has begun and the Underlying ETP's share price has decreased in value by more than 20%, an investor purchasing or selling shares at that time may not benefit from subsequent gains in the share price of the Underlying ETPs and/or Bitcoin Index until the Floor is reached and exceeded again (i.e., the share price of the Underlying ETPs and/or Bitcoin Index has recovered to a loss of only 20% from the start of the Outcome Period). |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 80% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the approximately twelve (12) months options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 80% protected against the Spot bitcoin's downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Liquidity Risk — FLEX Options — If and when available, in the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

The trading in Listed Options may be less deep and liquid than the market for certain other exchange traded option contracts. In a less liquid market for the Listed Options terminating the Listed Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of Listed Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its Listed Option positions.

| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Risk — The risk that the securities markets will increase or decrease in value is considered market risk and applies to any security.

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new put and call options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Premium-Discount Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Premium-Discount Risk — Fund Shares may trade above or below their NAV. The market prices of Fund Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Fund Shares on the Exchange. The trading price of Fund Shares may deviate significantly from NAV during periods of market volatility. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Secondary Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Government Security Risk — Some securities issued by U.S. Government agencies or government-sponsored enterprises are not backed by the full faith and credit of the U.S. and may only be supported by the right of the agency or enterprise to borrow from the U.S. Treasury. There can be no assurance that the U.S. Government will always provide financial support to those agencies or enterprises. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - January | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the securities held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Cap Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 80% of the negative price return of Spot bitcoin (before total fund operating fees and expenses over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses (with a maximum loss of 20% of Spot bitcoin over the duration of the Outcome Period), if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Floor that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Floor will not protect any decreases in the price of Spot bitcoin to the extent of such appreciation, and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Floor until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents (and therefore the Floor) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while seeking to protect against the downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the price return of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, the Underlying ETPs' holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors (the managers or organizations in charge of creating and administering a given ETP) do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Costs of Buying and Selling Fund Shares [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The Index prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs and/or Bitcoin Index. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and therefore the value of the Underlying ETPs and/or Bitcoin Index may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs' shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs and/or Bitcoin Index. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the Underlying ETPs and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the bitcoin price as reflected by the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause the ARK 21Shares Bitcoin ETF to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better aligns with the ARK 21Shares Bitcoin ETF's investment objective and strategy. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Floor Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Floor Risk — The Fund will be subject to the first 20% of the negative price return of Spot bitcoin, and there can be no guarantee that the Fund will be successful in its strategy to limit the losses in excess of the first 20% experienced by the Underlying ETPs and/or Bitcoin Index during an Outcome Period. The Fund does not provide principal protection or protection of gains and shareholders could experience significant losses including loss of their entire investment. In addition, the Fund's NAV may not change significantly when the share price of the Underlying ETPs and/or Bitcoin Index is materially below the Floor. If the Outcome Period has begun and the Underlying ETP's share price has decreased in value by more than 20%, an investor purchasing or selling shares at that time may not benefit from subsequent gains in the share price of the Underlying ETPs and/or Bitcoin Index until the Floor is reached and exceeded again (i.e., the share price of the Underlying ETPs and/or Bitcoin Index has recovered to a loss of only 20% from the start of the Outcome Period). |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 80% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the approximately twelve (12) months options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 80% protected against the Spot bitcoin's downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

The trading in Listed Options may be less deep and liquid than the market for certain other exchange traded option contracts. In a less liquid market for the Listed Options terminating the Listed Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of Listed Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its Listed Option positions.

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Market Risk [Member] | |
| Prospectus [Line Items] | |

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new put and call options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |

| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | U.S. Government Security Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Government Security Risk — Some securities issued by U.S. Government agencies or government-sponsored enterprises are not backed by the full faith and credit of the U.S. and may only be supported by the right of the agency or enterprise to borrow from the U.S. Treasury. There can be no assurance that the U.S. Government will always provide financial support to those agencies or enterprises. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - April | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Risk Nondiversified Status [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Non-Diversification Risk — The Fund is classified as "non-diversified" under the 1940 Act. As a result, the Fund is only limited as to the percentage of its assets which may be invested in the securities of any one issuer by the diversification requirements imposed by the Internal Revenue Code of 1986, as amended (the "Code"). |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Authorized Participant Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Authorized Participant Concentration Risk — Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the securities held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Cap Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 80% of the negative price return of Spot bitcoin (before total fund operating fees and expenses over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses (with a maximum loss of 20% of Spot bitcoin over the duration of the Outcome Period), if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Floor that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Floor will not protect any decreases in the price of Spot bitcoin to the extent of such appreciation, and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Floor until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents (and therefore the Floor) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while seeking to protect against the downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the price return of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, the Underlying ETPs' holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors (the managers or organizations in charge of creating and administering a given ETP) do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Costs of Buying and Selling Fund Shares [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The Index prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs and/or Bitcoin Index. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and therefore the value of the Underlying ETPs and/or Bitcoin Index may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs' shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs and/or Bitcoin Index. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the Underlying ETPs and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the bitcoin price as reflected by the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets.

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Floor Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Floor Risk — The Fund will be subject to the first 20% of the negative price return of Spot bitcoin, and there can be no guarantee that the Fund will be successful in its strategy to limit the losses in excess of the first 20% experienced by the Underlying ETPs and/or Bitcoin Index during an Outcome Period. The Fund does not provide principal protection or protection of gains and shareholders could experience significant losses including loss of their entire investment. In addition, the Fund's NAV may not change significantly when the share price of the Underlying ETPs and/or Bitcoin Index is materially below the Floor. If the Outcome Period has begun and the Underlying ETP's share price has decreased in value by more than 20%, an investor purchasing or selling shares at that time may not benefit from subsequent gains in the share price of the Underlying ETPs and/or Bitcoin Index until the Floor is reached and exceeded again (i.e., the share price of the Underlying ETPs and/or Bitcoin Index has recovered to a loss of only 20% from the start of the Outcome Period). |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Investment Timing Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 80% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the approximately twelve (12) months options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 80% protected against the Spot bitcoin's downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Market Risk [Member] | |
| Prospectus [Line Items] | |

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new put and call options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |

| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - July | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |

In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |

To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. Authorized Participant concentration risk may be heightened for ETFs, such as the Fund, that invest in securities issued by non-U.S. issuers or other securities or instruments that have lower trading volumes. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Underlying ETP Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Underlying ETP Risk — The Fund may invest in OTC Options and, if and when available, FLEX Options and/or Listed Options that reference an Underlying ETP, which subjects the Fund to certain of the risks of owning shares of one or more Underlying ETPs as well as the types of instruments in which the Underlying ETPs invest. The value of an Underlying ETP will fluctuate over time based on fluctuations in the values of the securities held by the Underlying ETP, which may be affected by changes in general economic conditions, expectations for future growth and profits, interest rates and the supply and demand for those securities. In addition, Underlying ETPs are subject to absence of an active market risk, premium/discount risk, tracking error risk and trading issues risk. Brokerage, tax and other expenses may negatively impact the performance of the Underlying ETPs and, in turn, the value of the Fund's shares. It is possible that the performance of each Underlying ETP will not be positively correlated to the performance of Spot bitcoin. An Underlying ETP that tracks an index may not exactly track the performance of the Index due to cash drag, differences between the portfolio of the Underlying ETP and the components of the Index, expenses and other factors. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Cap Change Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Change Risk — A new Cap is established at the beginning of each Outcome Period and is dependent on prevailing market conditions at the time the Cap is established. As such, the Cap may rise or fall from one Outcome Period to the next and is unlikely to remain the same for consecutive Outcome Periods. Investors should monitor the changes in the Cap for each Outcome Period, information for which will be made available pursuant to the procedure outlined in the Fund's prospectus. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Cap Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cap Risk — There can be no guarantee that the Fund will be successful in its strategy to provide protection against 80% of the negative price return of Spot bitcoin (before total fund operating fees and expenses over the Outcome Period. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin (up to the Cap), while attempting to limit downside losses (with a maximum loss of 20% of Spot bitcoin over the duration of the Outcome Period), if Fund Shares are held at the time at which the Fund enters into OTC Options or, if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents and held until those instruments expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these instruments were entered into or sells Fund Shares prior to the expiration (or maturity) of these investments, the Floor that the Fund seeks to provide may not be available. If the Outcome Period has begun and the price of Spot bitcoin has increased in value, the Floor will not protect any decreases in the price of Spot bitcoin to the extent of such appreciation, and therefore an investor may experience losses from this appreciated value until the Fund reaches its original NAV from the commencement of the Outcome Period. Similarly, if an investor purchases Fund Shares after the commencement of the Outcome Period and the price of Spot bitcoin has increased in value, an investor purchasing Fund Shares at that point will not benefit from the Floor until the price of Spot bitcoin decreases to its original value at the commencement of the Outcome Period. Accordingly, such investor will not receive the protection that the Fund seeks to provide until the Fund experiences losses that return it to its value at the commencement of the Outcome Period. If the OTC Options, and if and when available, FLEX Options and/or Listed Options and U.S. Treasury securities, if applicable, and cash and cash equivalents (and therefore the Floor) do not perform as expected, an investor may experience significant losses on its investment, including the loss of its entire investment. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Capped Upside Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Capped Upside Risk — The Fund's strategy seeks to provide returns that are subject to the Cap. In the event that the price of Spot bitcoin increases to an amount in excess of the Cap for the Outcome Period, the Fund will not participate in, and will underperform the price of Spot bitcoin to the extent of, those gains beyond the Cap. The Fund's strategy seeks to deliver returns that track those of Spot bitcoin by investing in OTC Options, and if and when available, FLEX Options and/or Listed Options referencing one or more of the Underlying ETPs and/or one or more Bitcoin Indexes (up to the Cap), while seeking to protect against the downside losses of the price of Spot bitcoin if Fund Shares are held at the time at which the Fund enters into OTC Options and, if and when available, FLEX Options and/or Listed Options and held until they expire at the end of the Outcome Period. In the event an investor purchases Fund Shares after these investments were entered into, there may be little or no ability for that investor to experience an investment gain on their Fund Shares (and such investor may be subjected to potential losses between that Fund Share price and the Fund's NAV at the commencement of the Outcome Period). Further, because the OTC Options and, if and when available FLEX Options and/or Listed Options are designed to produce returns that track the price return of Spot bitcoin (subject to the Cap) on the last day of the Outcome Period, if an investor sells Fund Shares prior to the expiration date of these investments, such investor may sell at a point where the Fund's performance does not track the performance of Spot bitcoin over the Outcome Period, and therefore may sell at a point where the Fund has underperformed the price of Spot bitcoin. Each type of option or a combination of each such options are expected to be used by the Fund if and when they do become available. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Cash Holdings Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Cash Holdings Risk — To the extent the Fund holds cash positions, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund's performance and ability to achieve its investment objective. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Concentration Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Concentration Risk — Underlying ETPs — The Underlying ETPs hold only bitcoin and cash. As a result, the Underlying ETPs' holdings are not diversified. Accordingly, the Underlying ETPs' net asset value may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the shares of the Underlying ETPs. The Underlying ETPs are a passive investment vehicle that do not seek to generate returns beyond tracking the price of bitcoin. The Sponsors do not actively manage the bitcoin held by the Underlying ETPs. This means the Sponsors (the managers or organizations in charge of creating and administering a given ETP) do not speculatively sell bitcoin at times when its price is high or speculatively acquire bitcoin at low prices in the expectation of future price increases. It also means the Underlying ETPs will not utilize leverage, derivatives or any similar arrangements in seeking to meet its investment objective. Any losses sustained by the Underlying ETPs will adversely affect the value of its shares. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Clearing Member Default Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Clearing Member Default Risk — Transactions in certain options such as FLEX Options and Listed Options are required to be centrally cleared ("cleared options"). In a transaction involving cleared options, the Fund's counterparty is a clearing house, such as the OCC, rather than a bank or broker. Since the Fund is not a member of clearing houses and only members of a clearing house ("clearing members") can participate directly in the clearing house, the Fund will hold cleared options through accounts at clearing members. In cleared options positions, the Fund will make payments (including margin payments) to, and receive payments from, a clearing house through their accounts at clearing members. Margin requirements are set by the OCC and the Fund's clearing member and generally may be increased at any time. Margin requirements could increase significantly during periods of volatility or market disruptions, and the Fund may be forced to sell assets at a disadvantageous time or price to meet such margin calls, which could negatively impact the Fund's performance. Customer funds held at a clearing organization in connection with any option contracts are held in a commingled omnibus account and are not identified to the name of the clearing member's individual customers. As a result, assets deposited by the Fund with any clearing member as margin for its options contracts may, in certain circumstances, be used to satisfy losses of other clients of the Fund's clearing member. In addition, although clearing members guarantee performance of their clients' obligations to the clearing house, there is a risk that the assets of the Fund might not be fully protected in the event of the clearing member's bankruptcy. The Fund is also subject to the risk that a limited number of clearing members are willing to transact on the Fund's behalf, which heightens the risks associated with a clearing member's default. If a clearing member defaults the Fund could lose some or all of the benefits of a transaction entered into by the Fund with the clearing member. The loss of a clearing member for the Fund to transact with could result in increased transaction costs and other operational issues that could impede the Fund's ability to implement its investment strategy. If the Fund cannot find a clearing member to transact with on the Fund's behalf, the Fund may be unable to effectively implement its investment strategy. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Correlation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Correlation Risk — Prior to the expiration date of any options held by the Fund, the value of the options will be determined based upon market quotations or using other recognized pricing methods, consistent with the Fund's valuation policy. Because a component of the options' value will be affected by, among other things, changes in the share prices of the Underlying ETPs and/or Bitcoin Index, changes in interest rates, changes in the actual and implied volatility of the of the Underlying ETPs and/or Bitcoin Index and bitcoin and the remaining time until the options expire, the value of the Fund's options positions is not anticipated to increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index, and it is possible they may move in different directions, and as a result, the Fund's NAV may not increase or decrease at the same rate as the share price of the Underlying ETPs and/or Bitcoin Index. If the assets held by the Fund do not perform as expected, the Fund may experience losses which may be significant. The Fund's strategy is designed to produce the outcomes upon the expiration of the options on or before the last business day of the Outcome Period, and it should not be expected that the outcomes will be provided at any point other than the end of the Outcome Period. While the performance of the Underlying ETPs and/or Bitcoin Index is expected to be positively correlated to the performance of Spot bitcoin, it is possible that the performance of the Underlying ETPs and/or Bitcoin Index will not be so correlated, which could cause the Fund to suffer losses. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Costs of Buying and Selling Fund Shares [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Costs of Buying and Selling Fund Shares — Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Counterparty Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Counterparty Risk — The use of OTC Options involves the risk that a loss may be sustained as a result of the failure of the Counterparty to make required payments or otherwise comply with the contract's terms. For example, in an option contract, this involves the risk to the option buyer that the writer will not buy or sell the underlying asset as agreed. In general, counterparty risk can be reduced by having an organization with extremely good credit act as an intermediary between the two parties. As OTC Options are not centrally cleared, no such organization exists in connection with these options. This risk may be heightened to the extent the Fund transacts with a counterparty that is not registered with any federal or state financial regulator. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Derivatives Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Derivatives Risk — Derivatives are instruments, such as options, futures and forward foreign currency contracts, whose value is derived from that of other assets, rates or indices. The use of derivatives for non-hedging purposes may be considered more speculative than other types of investments. Derivatives can be used for hedging (attempting to reduce risk by offsetting one investment position with another) or non-hedging purposes. Hedging with derivatives may increase expenses, and there is no guarantee that a hedging strategy will work. While hedging can reduce or eliminate losses, it can also reduce or eliminate gains. In addition, derivative instruments are subject to counterparty risk, meaning that the party with whom the Fund enters into a derivative transaction may experience a significant credit event and/or may be unwilling or unable to make timely settlement payments or otherwise honor its obligations. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and the Fund could lose more than the principal amount invested. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Digital Assets Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Digital Assets Risk — Risk factors related to digital assets include: - The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including further declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index and the Underlying ETPs and/or Bitcoin Index could lose all or substantially all of their value. - The value of the Underlying ETPs and/or Bitcoin Index are subject to a number of factors relating to the fundamental investment characteristics of bitcoin as a digital asset, including the fact that digital assets are bearer instruments and loss, theft, destruction, or compromise of the associated private keys could result in permanent loss of the asset, and the capabilities and development of blockchain technologies such as the Bitcoin Blockchain. - Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Indexes depend on the acceptance of bitcoin. - Changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. Risk factors related to digital asset markets include: - The value of the Underlying ETPs and/or Bitcoin Index relate to the value of bitcoins, the value of which may be highly volatile and subject to fluctuations due to a number of factors. - The BRRNY and similar pricing sources have a limited performance history, their rates price could fail to track the global bitcoin price, and a failure of the price could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. - While the Fund's investment objective is to track the positive price return of the BRRNY in the manner described previously, the BRRNY is only one source of spot bitcoin pricing and it may not track to a generally accepted bitcoin price. - The Index prices used to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Shares. The value of the Underlying ETPs and/or Bitcoin Index relates directly to the value of bitcoin, the value of which may be highly volatile and subject to fluctuations due to a number of factors that could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. Those factors include: - an increase in the global bitcoin supply or a decrease in global bitcoin demand; - market conditions of, and overall sentiment towards, the digital assets and blockchain technology industry; - the adoption of bitcoin as a medium of exchange, store-of-value or other consumptive asset and the maintenance and development of the open-source software protocol of the bitcoin network, and its ability to meet user demands; - manipulative trading activity on digital asset trading platforms, which, in many cases, are largely unregulated; - forks in the bitcoin network (a fork can introduce new security and operability risks to the original and the new networks, and may adversely impact confidence in the digital assets, and consequentially, their value); - investors' expectations with respect to interest rates, the rates of inflation of fiat currencies or bitcoin, and digital asset exchange rates; - consumer preferences and perceptions of bitcoin specifically and digital assets generally; - negative events, publicity, and social media coverage relating to the digital assets and blockchain technology industry; - fiat currency withdrawal and deposit policies on digital asset trading platforms; - the liquidity of digital asset markets and any increase or decrease in trading volume or market making on digital asset markets; - business failures, bankruptcies, hacking, fraud, crime, government investigations, or other negative developments affecting digital asset businesses, including digital asset trading platforms, or banks or other financial institutions and service providers which provide services to the digital assets industry; the use of leverage in digital asset markets, including the unwinding of positions, "margin calls", collateral liquidations and similar events; - investment and trading activities of large or active consumer and institutional users, speculators, miners, and investors in bitcoin; - an active derivatives market for bitcoin or for digital assets generally; - monetary policies of governments, legislation or regulation, trade restrictions, currency devaluations and revaluations and regulatory measures or enforcement actions, if any, that restrict the use of bitcoin as a form of payment or the purchase of bitcoin on the digital asset markets; - global or regional political, economic or financial conditions, events and situations, or major public issues; - fees associated with processing a bitcoin transaction and the speed at which bitcoin transactions are settled; - the maintenance, troubleshooting, and development of the bitcoin network including by miners and developers worldwide; - the ability for the bitcoin network to attract and retain miners to secure and confirm transactions accurately and efficiently; - ongoing technological viability and security of the bitcoin network and bitcoin transactions, including vulnerabilities against hacks and scalability; - financial strength of market participants; - the availability and cost of funding and capital; - the liquidity and credit risk of digital asset trading platforms; - interruptions in service from or closures or failures of major digital asset trading platforms or their banking partners, or outages or system failures affecting the bitcoin network; - decreased confidence in digital assets and digital assets trading platforms; - poor risk management or fraud by entities in the digital assets ecosystem; - increased competition from other forms of digital assets or payment services; and - the acquisitions or dispositions of bitcoin by one or more of the Underlying ETPs, since there is no limit on the number of bitcoin that the Underlying ETPs may acquire. The trading prices of many digital assets, including bitcoin, have experienced extreme volatility and may continue to do so. Extreme volatility in the future, including declines in the trading prices of bitcoin, could have a material adverse effect on the value of the Underlying ETPs and/or Bitcoin Index. The digital asset markets may still be experiencing a bubble or may experience a bubble again in the future. The value of a bitcoin is subject to momentum pricing due to speculation regarding future appreciation in value rather than robust fundamental analysis, leading to greater volatility. Digital assets represent a new and rapidly evolving industry, and the value of the Underlying ETPs and/or Bitcoin Index depends on the market acceptance of bitcoin. Digital asset networks, including the Bitcoin peer-to-peer network and associated blockchain ledger (the "Bitcoin Blockchain" and together the "bitcoin network"), and the software used to operate them are in the early stages of development. Given the recentness of the development of digital asset networks, digital assets may not function as intended and parties may be unwilling to use digital assets, which would dampen the growth, if any, of digital asset networks. Because bitcoin is a digital asset, the value of each of the Underlying ETPs' shares is subject to a number of factors relating to the fundamental investment characteristics of digital assets, including the fact that digital assets are bearer instruments and loss, theft, compromise, or destruction of the associated private keys could result in permanent loss of the asset. In addition, the Bitcoin Blockchain has experienced in the past, and may experience in the future, several quirks and unique events, including the first block of bitcoin being untradeable; a 2013 change in how transactions were processed leading to a temporary split in the blockchain; the blockchain experiencing small reorganizations due to network propagation issues or miner behavior; and the block subsidy halving in 2020 taking longer than expected due to slower block times. Digital asset networks are dependent upon the internet. A disruption of the internet or a digital asset network, such as the bitcoin network, would affect the ability to transfer digital assets, including bitcoin, and, consequently, their value. To the extent that any miners cease to record transactions that do not include the payment of a transaction fee in solved blocks or do not record a transaction because the transaction fee is too low, such transactions will not be recorded on the Bitcoin Blockchain until a block is mined by a miner who does not require the payment of transaction fees or is willing to accept a lower fee. Any widespread delays in the recording of transactions could result in a loss of confidence in a digital asset network. If the digital asset award for mining blocks and transaction fees for recording transactions on the bitcoin network are not sufficiently high to incentivize miners, or if certain jurisdictions continue to limit mining activities, miners may cease expanding processing power to mine blocks, could demand high transaction fees or confirmations of transactions on the Bitcoin Blockchain could be slowed, each of which could negatively impact the value of bitcoin and the value of the Underlying ETPs and/or Bitcoin Index. Digital asset mining operations can consume significant amounts of electricity, which may have a negative environmental impact and give rise to public opinion against allowing, or government regulations restricting, the use of electricity for mining operations. Additionally, miners may be forced to cease operations during an electricity shortage or power outage, or if electricity prices increase where the mining activities are performed. The open-source structure of many digital asset network protocols, such as the protocol for the bitcoin network, means that developers and other contributors are generally not directly compensated for their contributions in maintaining and developing such protocols. A loose community referred to as the "core developers" and other contributors to the bitcoin network are generally not directly compensated for their contributions in maintaining and developing the bitcoin network protocol. A failure to properly monitor and upgrade the bitcoin network protocol could damage the bitcoin network and the value of the Underlying ETPs and/or Bitcoin Index. Bitcoin is rewarded solely for mining activity and is not sold to raise capital for the Bitcoin network, and the bitcoin network protocol itself is made available for free rather than sold or made available subject to licensing or subscription fees and its use does not generate revenues for its development team. Consequently, there is a lack of financial incentive for developers to maintain or develop the bitcoin network and the core developers may lack the resources to adequately address emerging issues with the bitcoin network protocol. Although the bitcoin network is currently supported by the core developers, there can be no guarantee that such support will continue or be sufficient in the future. For example, the bitcoin network is maintained and developed largely on a GitHub resource section dedicated to bitcoin development, and there have been recent reports that the number of core developers who have the authority to make amendments to the bitcoin network's source code in the GitHub repository is relatively small, although there are believed to be a larger number of developers who contribute to the overall development of the source code of the bitcoin network. Alternatively, some developers may be funded by entities whose interests are at odds with other participants in the bitcoin network. In addition, a bad actor could also attempt to interfere with the operation of the bitcoin network by attempting to exercise a malign influence over a core developer. To the extent that material issues arise with the bitcoin network protocol and the core developers and open-source contributors are unable to address the issues adequately or in a timely manner, the bitcoin network and therefore the value of the Underlying ETPs and/or Bitcoin Index may be adversely affected. The core developers can propose amendments to the bitcoin network's source code that, if accepted by miners and users, could alter the protocols and software of the bitcoin network and the properties of bitcoin. These alterations would occur through software upgrades, and could potentially include changes to the irreversibility of transactions and limitations on the mining of new bitcoin, which could undermine the appeal and market value of bitcoin. Alternatively, software upgrades and other changes to the protocols of the bitcoin network could fail to work as intended or could introduce bugs, security risks, or otherwise adversely affect, the speed, security, usability, or value of the bitcoin network or bitcoins. As a result, the bitcoin network could be subject to changes to its protocols and software in the future that may adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The acceptance of software patches or upgrades by a significant, but not overwhelming, percentage of the users and miners in a digital asset network, such as the bitcoin network, could result in a "fork" in such network's blockchain, including the Bitcoin Blockchain, resulting in the operation of multiple separate networks. Even where amendments are approved by all or substantially all of the users and miners of bitcoin network, those amendments to the protocols and software could adversely affect the value of the Underlying ETPs and/or Bitcoin Index. The Bitcoin Blockchain has experienced forks previously. The governance of decentralized networks, such as the bitcoin network, is by voluntary consensus and open competition. As a result, there may be a lack of consensus or clarity on the governance of any particular decentralized digital asset network, which may stymie such network's utility and ability to grow and face challenges. As a result, there may be a lack of consensus or clarity on the governance of the bitcoin network, which may stymie the bitcoin network's utility and ability to grow and face challenges. In particular, it may be difficult to find solutions or martial sufficient effort to overcome any future problems on the bitcoin network, especially long-term problems. Further, changes in the governance of a digital asset network may not receive sufficient support from users and miners, which may negatively affect that digital asset network's ability to grow and respond to challenges. The foregoing notwithstanding, the protocols for some decentralized networks, such as the bitcoin network, are informally managed by a group of core developers that propose amendments to the relevant network's source code. Core developers' roles evolve over time, largely based on self-determined participation. As a result of the foregoing, it may be difficult to find solutions or marshal sufficient effort to overcome any future problems, especially long-term problems, on digital asset networks. If a significant majority of users and miners adopt amendments to a decentralized network based on the proposals of such core developers, such network will be subject to new protocols that may adversely affect the value of the relevant digital asset. The Underlying ETPs are not actively managed and will not have any formal strategy relating to the development of the bitcoin network. Moreover, in the past, flaws in the source code for digital assets have been exposed and exploited, including flaws that disabled some functionality for users, exposed users' personal information and/or resulted in the theft of users' digital assets. The cryptography underlying bitcoin could prove to be flawed or ineffective, or developments in mathematics and/or technology, including advances in digital computing, algebraic geometry and quantum computing, could result in such cryptography becoming ineffective. In any of these circumstances, a malicious actor may be able to compromise the security of the bitcoin network or take the Underlying ETPs' bitcoin, which would adversely affect the value of the Underlying ETPs' shares. Moreover, functionality of the bitcoin network may be negatively affected such that it is no longer attractive to users, thereby dampening demand for bitcoin. Even if another digital asset other than bitcoin were affected by similar circumstances, any reduction in confidence in the source code or cryptography underlying digital assets generally could negatively affect the demand for digital assets and therefore adversely affect the value of the Underlying ETPs and/or Bitcoin Index. All networked systems are vulnerable to various kinds of attacks. As with any computer network, the bitcoin network contains certain flaws. For example, the bitcoin network is currently vulnerable to a "51% attack" where, if a miner or mining pool were to gain control of more than 50% of the hash rate for a bitcoin network, it would be able to prevent new transactions from being confirmed, and reverse new transactions that are completed while they are in control of the network, effectively enabling them to double-spend their bitcoins. In addition, many digital asset networks have been subjected to a number of denial-of-service attacks, which has led to temporary delays in block creation and in the transfer of bitcoin. Any similar attacks on the bitcoin network that impact the ability to transfer bitcoin could have a material adverse effect on the price of bitcoin and the value of the Fund Shares. Bitcoin has only recently become selectively accepted as a means of payment by retail and commercial outlets, and use of bitcoin by consumers to pay such retail and commercial outlets remains limited. Banks and other established financial institutions may refuse to process funds for bitcoin transactions, process wire transfers to or from digital asset trading platforms, bitcoin-related companies or service providers or maintain accounts for persons or entities transacting in bitcoin. As a result, the price of bitcoin may be influenced to a significant extent by speculators and miners, thus contributing to price volatility that makes retailers less likely to accept it as a form of payment in the future. Volatility in the price of digital assets may dampen liquidity in the market and damage the public perception of digital assets generally or any one digital asset in particular, such as bitcoin, and their or its utility as a payment system, which could decrease the price of digital assets generally or individually. Further, the lack of availability of banking services could prevent the Underlying ETPs from being able to complete creations and redemptions of Baskets, the timely liquidation of bitcoin and withdrawal of assets from the custodians on behalf of the respective Underlying ETPs, even if the Underlying ETPs' sponsors determined that such liquidation was appropriate or suitable, or otherwise disrupt the Underlying ETPs' operations. Certain privacy-preserving features have been or are expected to be introduced to digital asset networks, such as the bitcoin network, and platforms or businesses that facilitate transactions in bitcoin may be at an increased risk of criminal or civil lawsuits, or of having banking services cut off, if there is a concern that these features interfere with the performance of anti-money laundering duties and economic sanctions checks or facilitate illicit financing or crime. Users, developers and miners may otherwise switch to or adopt certain digital assets at the expense of their engagement with other digital asset networks, which may negatively impact those networks, including the bitcoin network. Competition from the emergence or growth of other digital assets or methods of investing in bitcoin could have a negative impact on the price of bitcoin and adversely affect the value of the Fund Shares. Many digital asset networks, including the bitcoin network, face significant scaling challenges due to the fact that public blockchains generally face a tradeoff between security and scalability. One means through which public blockchains achieve security is decentralization, meaning that no intermediary is responsible for securing and maintaining these systems. For example, a greater degree of decentralization generally means a given digital asset network is less susceptible to manipulation or capture. A digital asset network may be limited in the number of transactions it can process by the capabilities of each single fully participating node. Attempts to increase the volume of transactions may not be effective, and such upgrades may fail, resulting in potentially irreparable damage to the bitcoin network and to the value of bitcoin. If corresponding increases in network throughput lag behind growth in the use of digital asset networks, average fees and settlement times may increase considerably. For example, the bitcoin network has been, at times, at capacity, which has led to increased transaction fees. Since January 1, 2019, bitcoin transaction fees have increased from $0.18 per-bitcoin transaction, on average, to a high of $60.95 per transaction, on average, on April 20, 2021. As of December 31, 2023, bitcoin transaction fees were $4.45 per transaction, on average, over a one-year trailing basis. Increased fees and decreased settlement speeds could preclude certain uses for bitcoin (e.g., micropayments), and could reduce demand for, and the price of, bitcoin, which could adversely impact the value of the Underlying ETPs and/or Bitcoin Index. In May 2023, events related to the adoption of ordinals, which are a means of inscribing digital content on the Bitcoin Blockchain, caused transaction fees to temporarily spike above $30 per transaction. There is no guarantee that any of the mechanisms in place or being explored for increasing the scale of settlement of the bitcoin network transactions will be effective, or how long these mechanisms will take to become effective, which could cause the bitcoin network to not adequately resolve scaling challenges and adversely impact the adoption of bitcoin as a medium of exchange and the value of the Underlying ETPs and/or Bitcoin Index. Digital assets may have concentrated ownership — large holders referred to as "whales" — and large sales or distributions by holders of such digital assets could have an adverse effect on the market price of such digital assets. Given the large amount of bitcoin they hold, these holders have the ability to manipulate the price of bitcoin. The largest bitcoin wallets are believed to hold, in aggregate, a significant percentage of the bitcoins in circulation. Moreover, it is possible that other persons or entities control multiple wallets that collectively hold a significant number of bitcoins, even if they individually only hold a small amount, and it is possible that some of these wallets are controlled by the same person or entity. As a result of this concentration of ownership, large sales or distributions by such holders could have an adverse effect on the market price of bitcoin. The indexes utilized by the Underlying ETPs have a limited performance history, the index price could fail to track the global bitcoin price, and a failure of the index price could adversely affect the value of the Underlying ETPs' shares. The index prices used by the respective Underlying ETPs to calculate the value of the Underlying ETPs' bitcoin may be volatile, adversely affecting the value of the Underlying ETPs' shares. Because the Underlying ETPs hold only bitcoin and cash, an investment in the Underlying ETPs may be more volatile than an investment in a more broadly diversified portfolio. Accordingly, the Underlying ETPs' net asset values may be more volatile than another investment vehicle with a more broadly diversified portfolio and may fluctuate substantially over short or long periods of time. Fluctuations in the price of bitcoin are expected to have a direct impact on the value of the Underlying ETPs' shares. Digital asset trading platforms are relatively new and, in some cases, unlicensed, unregulated, operate without extensive supervision by governmental authorities. Many operate outside the United States and may be subject to significantly less stringent regulatory and compliance requirements in their local jurisdictions, may take the position that they are not subject to laws and regulations that would apply to a national securities exchange or designated contract market in the United States, or may, as a practical matter, be beyond the ambit of U.S. regulators. As a result, trading activity on or reported by these digital asset trading platforms is generally significantly less regulated than trading in regulated U.S. securities and commodities markets, and may reflect behavior that would be prohibited in regulated U.S. trading venues. Furthermore, while many prominent digital asset trading platforms provide the public with significant information regarding their ownership structure, management teams, corporate practices, cybersecurity and regulatory compliance, many digital asset trading platforms do not provide this information. Digital asset trading platforms may not be subject to, or may not be operating in compliance with, regulation in a similar manner as other regulated trading platforms, such as national securities exchanges or designated contract markets. As a result, the marketplace may lose confidence in digital asset trading platforms, including prominent platforms that handle a significant volume of bitcoin trading. Digital asset trading platforms are subject to enforcement actions by regulatory authorities and may be operating out of compliance with regulation. The bitcoin market globally and in the United States is not subject to comparable regulatory guardrails as exist in regulated securities markets. Furthermore, many bitcoin trading venues lack certain safeguards put in place by exchanges for more traditional assets to enhance the stability of trading on the exchanges and prevent "flash crashes," such as limit-down circuit breakers. As a result, the prices of bitcoin on trading venues may be subject to larger and/or more frequent sudden declines than assets traded on more traditional exchanges. Tools to detect and deter fraudulent or manipulative trading activities such as market manipulation, front-running of trades, and wash-trading may not be available to or employed by digital asset trading platforms, or may not exist at all. The SEC has identified possible sources of fraud and manipulation in the bitcoin market generally, including, among others: (1) "wash trading"; (2) persons with a dominant position in bitcoin manipulating bitcoin pricing; (3) hacking of the bitcoin network and trading platforms; (4) malicious control of the bitcoin network; (5) trading based on material, non-public information (for example, plans of market participants to significantly increase or decrease their holdings in bitcoin, new sources of demand for bitcoin) or based on the dissemination of false and misleading information; (6) manipulative activity involving purported "stablecoins," including Tether (the price of bitcoin may be affected due to stablecoins (including Tether and U.S. Dollar Coin (USDC)), the activities of stablecoin issuers and their regulatory treatment); and (7) fraud and manipulation at bitcoin trading platforms. The effect of potential market manipulation, front-running, wash-trading, and other fraudulent or manipulative trading practices may inflate the volumes actually present in crypto market and/or cause distortions in price, which could adversely affect the Underlying ETPs and cause losses to the Fund. As digital assets have grown in both popularity and market size, the U.S. Congress and a number of U.S. federal and state agencies (including FinCEN, SEC, OCC, CFTC, FINRA, CFPB, the Department of Justice, the Department of Homeland Security, the Federal Bureau of Investigation, the IRS and state financial institution regulators) have been examining the operations of digital asset networks, digital asset users and the digital asset trading platform markets, with particular focus on the extent to which digital assets can be used to launder the proceeds of illegal activities or fund criminal or terrorist enterprises and the safety and soundness of exchanges or other service-providers that hold digital assets for users. Many of these state and federal agencies have issued consumer advisories regarding the risks posed by digital assets to investors. In addition, federal and state agencies, and other countries have issued rules or guidance about the treatment of digital asset transactions or requirements for businesses engaged in digital asset activity. However, no U.S. federal or state agency exercises comprehensive supervisory jurisdiction over global or domestic markets for bitcoin. U.S. state and federal, and foreign regulators and legislatures have taken action against virtual currency businesses or enacted restrictive regimes in response to adverse publicity arising from hacks, consumer harm, or criminal activity stemming from virtual currency activity. The U.S. Treasury Department has expressed concern regarding digital assets' potential to be used to fund illicit activities and may seek to implement new regulations governing digital asset activities to address these concerns. Digital asset markets in the United States exist in a state of regulatory uncertainty, and adverse legislative or regulatory developments could significantly harm the value of bitcoin or the Fund Shares, such as by banning, restricting or imposing onerous conditions or prohibitions on the use of bitcoins, mining activity, digital wallets, the provision of services related to trading and custodying bitcoin, the operation of the bitcoin network, or the digital asset markets generally. Various foreign jurisdictions have, and may continue to, in the near future, adopt laws, regulations or directives that may affect the bitcoin network, digital asset trading platforms, and their users, particularly digital asset trading platforms and service providers that fall within such jurisdictions' regulatory scope. There remains significant uncertainty regarding foreign governments' future actions with respect to the regulation of digital assets and digital asset trading platforms. Such laws, regulations or directives may conflict with those of the United States and may negatively impact the acceptance of bitcoin by users, merchants and service providers outside the United States and may therefore impede the growth or sustainability of the bitcoin economy in their jurisdictions or globally, or otherwise negatively affect the value of bitcoin. The effect of any future regulatory change on the Underlying ETPs and/or Bitcoin Index or on bitcoin is impossible to predict, but such change could be substantial and adverse to the Underlying ETPs and/or Bitcoin Index and the value of the Fund Shares. Competition from central bank digital currencies ("CBDCs") and emerging payments initiatives involving financial institutions could adversely affect the value of bitcoins and other digital assets. In addition, over the past several years, some digital asset trading platforms have been closed due to fraud and manipulative activity, business failure or security breaches. In many of these instances, the customers of such digital asset trading platforms were not compensated or made whole for the partial or complete losses of their account balances in such digital asset trading platforms. While, generally speaking, smaller digital asset trading platforms are less likely to have the infrastructure and capitalization that make larger digital asset trading platforms more stable, larger digital asset trading platforms are more likely to be appealing targets for hackers and malware and their shortcomings or ultimate failures are more likely to have contagion effects on the digital asset ecosystem, and therefore may be more likely to be targets of regulatory enforcement action. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Risks Associated with the Index [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Risks Associated with the Index — General — The failure of the respective Index methodology to measure the actual value of bitcoin could have an adverse effect on the Underlying ETPs and/or Bitcoin Index. In addition, the value of bitcoin as calculated by the Index methodology may differ from the value of bitcoin calculated by other methodologies and the price of bitcoin on any single spot market. The Underlying ETPs and/or Bitcoin Index may not achieve the desired degree of correlation between their performance and that of their respective Index and thus may not achieve their investment objective. With respect to the Underlying ETPs, the difference in performance may be due to factors such as fees, transaction costs, redemptions of, and subscriptions for, an Underlying ETP's shares, pricing differences, differences in the timing of the addition or removal of constituent exchanges underlying the Index used by the Underlying ETP to determine its NAV or the cost to the Underlying ETPs of complying with various new or existing regulatory requirements. Risks Associated with the Index — Underlying Funds — A. IBIT The Index used by IBIT to determine the net asset value of the iShares Bitcoin Trust ETF on each Business Day is based on the value of bitcoin as reflected by the index was developed by the CF Benchmarks Ltd., the "Index Administrator". The Index Administrator has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the IBIT's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Administrator does not have any obligation to take the needs of the IBIT fund, the IBIT fund's shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. By investing in IBIT, shareholders will have no rights against the Index Administrator or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Furthermore, because the number of digital asset trading platforms is limited, the Index will necessarily be comprised of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Index Administrator would have limited ability to remove such digital asset trading platform from the Index, which could skew the price of bitcoin as represented by the Index. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of IBIT's shares. B. BTC The Index used to price the shares of BTC is the CoinDesk Bitcoin Price Index (XBX) (the "Index") developed by CoinDesk indices, Inc. (the "Index Provider"). The Index is a U.S. dollar-denominated composite reference rate for the price of Bitcoin. The Index is designed to (1) mitigate the effects of fraud, manipulation and other anomalous trading activity from impacting the Bitcoin reference rate, (2) provide a real-time, volume-weighted fair value of Bitcoin and (3) appropriately handle and adjust for non-market related events. The Index Provider formally re-evaluates the weighting algorithm quarterly, but maintains discretion to change the way in which an Index Price is calculated based on its periodic review or in extreme circumstances. The exact methodology to calculate the Index Price is not publicly available. The Index is designed to limit exposure to trading or price distortion of any individual Digital Asset Trading Platform that experiences periods of unusual activity or limited liquidity by discounting, in real-time, anomalous price movements at individual Digital Asset Trading Platforms. The Digital Asset Trading Platforms that are included in the Index (the Constituent Trading Platforms) are selected by the Index Provider utilizing a methodology that is guided by the International Organization of Securities Commissions ("IOSCO") principles for financial benchmarks. For an exchange to become a Constituent Trading Platform, it must satisfy the Inclusion Criteria described in this prospectus, as may be updated by the Index Provider from time to time. The Index has a limited history and the Index Price is a composite reference rate calculated using trading price data from various Digital Asset Trading Platforms chosen by the Index Provider. The Index Provider may remove or add Digital Asset Trading Platforms to the Index in the future at its discretion. Although the Index is designed to accurately capture the market price of Bitcoin, third parties may be able to purchase and sell Bitcoin on public or private markets not included among the constituent Digital Asset Trading Platforms of the Index, and such transactions may take place at prices materially higher or lower than the Index Price. Moreover, there may be variances in the prices of Bitcoin on the various Digital Asset Trading Platforms, including as a result of differences in fee structures or administrative procedures on different Digital Asset Trading Platforms. The price of Bitcoin on public Digital Asset Trading Platforms has a limited history, and during this history, Bitcoin prices on the Digital Asset Markets more generally, and on Digital Asset Trading Platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the Index is designed to limit exposure to the interruption of individual Digital Asset Trading Platforms, the Index Price, and the price of Bitcoin generally, remains subject to volatility experienced by Digital Asset Trading Platforms, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of Digital Asset Trading Platforms is limited, the Index will necessarily be comprised of a limited number of Digital Asset Trading Platforms. If a Digital Asset Trading Platform were subjected to regulatory, volatility or other pricing issues, the Index Provider would have limited ability to remove such Digital Asset Trading Platform from the Index, which could skew the price of Bitcoin as represented by the Index. Trading on a limited number of Digital Asset Trading Platforms may result in less favorable prices and decreased liquidity of Bitcoin and, therefore, could have an adverse effect on the value of the Shares. C. BITB BITB will establish its net asset value with reference to the CME CF Bitcoin Reference Rate — New York Variant ("BRRNY") which is a standardized reference rate published by CF Benchmarks Ltd. (the "Benchmark Provider") that is designed to reflect the performance of bitcoin in U.S. dollars. The BRRNY is calculated by the Benchmark Provider based on an aggregation of executed trade flow of major bitcoin trading platforms ("Constituent Platforms"). The BRRNY currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six Constituent Platforms, which is the underlying rate to determine settlement of Chicago Mercantile Exchange ("CME") bitcoin futures contracts, except that the BRRNY is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The BRRNY and the BRR have a limited history and their value is an average composite reference rate calculated using volume-weighted trading price data from the Constituent Platforms. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess BRRNY's performance. The Benchmark Provider has substantial discretion at any time to change the methodology used to calculate the BRRNY, including the Constituent Platforms that contribute prices to the Bitwise Bitcoin Trust's NAV. The Benchmark Provider does not have any obligation to take the needs of the Bitwise Bitcoin Trust, the Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the BRRNY will appropriately track the price of bitcoin in the future. Neither the CME Group nor the Benchmark Provider has any obligation to take the needs of the Bitwise Bitcoin Trust or the Shareholders into consideration in determining, composing, or calculating the BRRNY or in the selection of the Constituent Platforms used. The Constituent Platforms are chosen by the Benchmark Provider, under the oversight of the CME CF Cryptocurrency Pricing Products Oversight Committee. Although the BRRNY is intended to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The pricing sources (Constituent Platforms) used by the BRRNY are digital asset trading venues that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in BRRNY calculations and, therefore, could adversely affect the bitcoin price as reflected by the BRRNY. The BRRNY is based on various inputs which may include price data from various third-party digital asset trading platforms. Neither the CME Group nor the Benchmark Provider guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. BITB utilizes the BRRNY to establish its NAV and NAV per Share. In the event that the BRRNY is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact an investment in the Shares or the Bitwise Bitcoin Trust's operations. The CME Bitcoin Real Time Price also has a limited history and shares some of the same structural and methodological features and risks as the BRRNY. The Bitwise Bitcoin Trust utilizes the CME Bitcoin Real Time Price to establish its Indicative Trust Value ("ITV"). The ITV is intended to provide additional information not otherwise available to the public that may be useful to investors and market professionals in connection with the trading of the Shares on the Exchange. It is calculated by using the prior day's holdings at close of business and the most recently reported price level of the CME Bitcoin Real Time Price. While investors are capable of assessing the intra-day movement of the price of the Shares and the bitcoin market price of bitcoin, Shareholders may use the ITV as a data point in their assessment of the value of the Shares. In the event that the CME Bitcoin Real Time Price is incorrectly calculated, is not timely calculated or changes its calculation methodology in the future, such an occurrence may adversely impact the utility of the ITV to Shareholders. Although the BRRNY and CME Bitcoin Real Time Price are designed to accurately capture the market price of bitcoin, third parties may be able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms of the BRRNY and CME Bitcoin Real Time Price, and such transactions may take place at prices materially higher or lower than the level of the BRRNY used to establish the NAV. To the extent such prices differ materially from the level of the BRRNY used to establish the NAV, investors may lose confidence in the Shares' ability to track the market price of bitcoin, which could adversely affect an investment in the Shares. The Sponsor, in its sole discretion, may cause the Bitwise Bitcoin Trust to price its portfolio based upon an index, benchmark or standard other than the BRRNY at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index, benchmark or standard better aligns with the Bitwise Bitcoin Trust's investment objective and strategy. The Sponsor may make this decision for a number of reasons, including, but not limited to, a determination that the BRRNY price of bitcoin differs materially from the global market price of bitcoin and/or that third parties are able to purchase and sell bitcoin on public or private markets not included among the Constituent Platforms, and such transactions may take place at prices materially higher or lower than the BRRNY price. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. The Constituent Platforms have changed over time. The price of bitcoin on public digital asset trading platforms has a limited history, and during this history, bitcoin prices on the digital asset markets more generally, and on digital asset trading platforms individually, have been volatile and subject to influence by many factors, including operational interruptions. While the BRRNY is designed to limit exposure to the interruption of individual digital asset trading platforms, the BRRNY price, and the price of bitcoin generally, remains subject to volatility experienced by digital asset exchanges, and such volatility could adversely affect the value of the Shares. Furthermore, because the number of liquid and credible digital asset trading platforms is limited, the BRRNY will necessarily be composed of a limited number of digital asset trading platforms. If a digital asset trading platform were subjected to regulatory, volatility or other pricing issues, the Benchmark Provider would have limited ability to remove such digital asset trading platform from the BRRNY, which could skew the price of bitcoin as represented by the BRRNY. Trading on a limited number of digital asset trading platforms may result in less favorable prices and decreased liquidity of bitcoin and, therefore, could have an adverse effect on the value of the Shares. D. FBTC The Fidelity Wise Origin Bitcoin Fund seeks to track the performance of bitcoin, as measured by the performance of the Fidelity Bitcoin Reference Rate (the "Index"), adjusted for the Fidelity Wise Origin Bitcoin Fund's expenses and other liabilities. The Fidelity Bitcoin Reference Rate is designed to reflect the performance of bitcoin in U.S. dollars. The Index is constructed using bitcoin price feeds from eligible bitcoin spot markets and the volume-weighted median price ("VWMP") methodology, calculated every 15 seconds based on VWMP spot market data over rolling sixty-minute increments to develop a bitcoin price composite. The Index methodology was developed by Fidelity Product Services LLC (the "Index Provider") and is monitored by the Fidelity Index Committee (the "Committee") with the assistance of the Fidelity Digital Asset Indices Advisory Committee. Coin Metrics, Inc. is the third-party calculation agent ("Calculation Agent") for the Index. The Index was developed by an affiliate of the Sponsor, the Index Provider. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the Fidelity Wise Origin Bitcoin Fund's NAV. Any such changes could affect the present, past and expected levels of the Index and could adversely affect performance of the Index. The Index Provider does not have any obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund, the Fidelity Wise Origin Bitcoin Fund's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the Fidelity Wise Origin Bitcoin Fund or the Shareholders into consideration in determining, composing, or calculating the Index. By investing in the Fidelity Wise Origin Bitcoin Fund, shareholders will have no rights against the Index Provider or any other persons that have discretion over the Index, even though these entities administer, oversee and determine the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the level of the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause FBTC to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better reflects the price of bitcoin. The Sponsor, however, is under no obligation whatsoever to make such changes in any circumstance. Using a VWMP methodology and price feeds from eligible bitcoin spot markets, the Index intends to represent the U.S. dollar value of one bitcoin every 15 seconds based on VWMP spot market data over rolling sixty-minute increments. As such, the VWMP methodology used to determine the NAV may not be reflective of market events and other developments that occur after its pricing window and thus this methodology may not be reflective of the then-available market price of bitcoin in periods between its calculation. Additionally, as the methodology references a median price, it may not reflect the price of bitcoin available for the Fidelity Wise Origin Bitcoin Fund to transact on any single spot market. The Sponsor does not intend, and disclaims any obligation, to determine whether the methodology used to determine the level of the Index accurately reflects the value of bitcoin or the price at which market transactions in bitcoin could be readily effected at any given time. E. ARKB ARKB investment objective is to track the performance of bitcoin as measured by the performance of the CME CF Bitcoin Reference Rate — New York Variant (the "Index"), adjusted for the ARK 21Shares Bitcoin ETF's expenses and other liabilities. The Index is calculated by CF Benchmarks Ltd. (the "Index Provider") based on an aggregation of executed trade flow of major bitcoin spot exchanges. The Index is designed to reflect the performance of bitcoin in U.S. dollars. The Index currently uses substantially the same methodology as the CME CF Bitcoin Reference Rate ("BRR"), including utilizing the same six bitcoin exchanges, which is the underlying rate to determine settlement of CME bitcoin futures contracts, except that the Index is calculated as of 4:00 p.m. Eastern time, whereas the BRR is calculated as of 4:00 p.m. London time. The Shares of the ARK 21Shares Bitcoin ETF are valued daily based on the Index. The Index was developed by the Index Provider and has a limited performance history. Although the Index is based on materially the same methodology (except calculation time) as the Index Provider's BRR, which was first introduced in November 2016, the Index itself has only been in operation since February 2022, and the Index has only featured its current roster of Constituent Exchanges since May 2022. A longer history of actual performance through various economic and market conditions would provide greater and more reliable information for an investor to assess the Index's performance. The Index Provider has substantial discretion at any time to change the methodology used to calculate the Index, including the spot markets that contribute prices to the ARK 21Shares Bitcoin ETF's NAV. The Index Provider does not have any obligation to take the needs of the ARK 21Shares Bitcoin ETF, the ARK 21Shares Bitcoin ETF's Shareholders, or anyone else into consideration in connection with such changes. There is no guarantee that the methodology currently used in calculating the Index will appropriately track the price of bitcoin in the future. The Index Provider has no obligation to take the needs of the ARK 21Shares Bitcoin ETF or the Shareholders into consideration in determining, composing, or calculating the Index. Pricing sources used by the Index are digital asset spot markets that facilitate the buying and selling of bitcoin and other digital assets. Although many pricing sources refer to themselves as "exchanges," they are not registered with, or supervised by, the SEC or CFTC and do not meet the regulatory standards of a national securities exchange or designated contract market. For these reasons, among others, purchases and sales of bitcoin may be subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets and government regulation and intervention. These circumstances could affect the price of bitcoin used in Index calculations and, therefore, could adversely affect the bitcoin price as reflected by the Index. The Index is based on various inputs which include price data from various third-party bitcoin spot markets. The Index Provider does not guarantee the validity of any of these inputs, which may be subject to technological error, manipulative activity, or fraudulent reporting from their initial source. The Sponsor, in its sole discretion, may cause the ARK 21Shares Bitcoin ETF to track (or price its portfolio based upon) an index or standard other than the Index at any time, with prior notice to the Shareholders, if investment conditions change or the Sponsor believes that another index or standard better aligns with the ARK 21Shares Bitcoin ETF's investment objective and strategy. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Equity Securities Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Equity Securities Risk — The securities markets are volatile, and the market prices of the Underlying ETPs' securities may decline generally. The price of equity securities fluctuates based on changes in a company's financial condition and overall market and economic conditions. If the market prices of the securities owned by the Underlying ETPs fall, the value of your investment in the Fund will decline. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Floor Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Floor Risk — The Fund will be subject to the first 20% of the negative price return of Spot bitcoin, and there can be no guarantee that the Fund will be successful in its strategy to limit the losses in excess of the first 20% experienced by the Underlying ETPs and/or Bitcoin Index during an Outcome Period. The Fund does not provide principal protection or protection of gains and shareholders could experience significant losses including loss of their entire investment. In addition, the Fund's NAV may not change significantly when the share price of the Underlying ETPs and/or Bitcoin Index is materially below the Floor. If the Outcome Period has begun and the Underlying ETP's share price has decreased in value by more than 20%, an investor purchasing or selling shares at that time may not benefit from subsequent gains in the share price of the Underlying ETPs and/or Bitcoin Index until the Floor is reached and exceeded again (i.e., the share price of the Underlying ETPs and/or Bitcoin Index has recovered to a loss of only 20% from the start of the Outcome Period). |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | FLEX Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • FLEX Options Risk — Trading FLEX Options involves risks different from, and possibly greater than, the risks associated with investing directly in securities or in other types of options. FLEX Options, like other listed options, are traded on the U.S. options markets and are issued by OCC. However, unlike other options, the terms of FLEX Options are not all standardized. When a FLEX Option is purchased and sold in an opening transaction, the parties to the transaction have the flexibility, within limitations set forth in the rules of the options market on which the transaction occurs, to fix certain of the option's terms. The flexibility to fix certain terms is what makes FLEX Options different from other types of options. Because many of the terms of FLEX Options are not standardized, it is less likely that there will be an active secondary market in which holders and writers of such options will be able to close out their positions by offsetting sales and purchases. Because FLEX Options have variable terms that are fixed by the parties, there are no pre-established series of FLEX Options. Rather, any different series of FLEX Options may be created and outstanding at any given time as a result of the various designations of variable terms that are made in different transactions. Secondary trading interest in FLEX Options may therefore be spread over a larger number of series than the trading interest in other options, the trading interest in any particular series of FLEX Options may be very limited, the secondary markets in FLEX Options may be less deep, liquid and continuous than the markets in other options on the same underlying interests, and the premiums for FLEX Options may not correlate with premiums for such other options. In the event that trading in the FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. In a less liquid market for the FLEX Options, liquidating the FLEX Options may require the payment of a premium (for written FLEX Options) or acceptance of a discounted price (for purchased FLEX Options) and may take longer to complete. A less liquid trading market may adversely impact the value of the FLEX Options and Fund Shares and result in the Fund being unable to achieve its investment objective. Less liquidity in the trading of the Fund's FLEX Options could have an impact on the prices paid or received by the Fund for the FLEX Options in connection with creations and redemptions of the Fund Shares. Depending on the nature of this impact to pricing, the Fund may be forced to pay more for redemptions (or receive less for creations) than the price at which it currently values the FLEX Options. Such overpayment or under collection may impact the value of the Fund and whether the Fund can satisfy its investment objective. Additionally, in a less liquid market for the FLEX Options, the liquidation of a large number of options may more significantly impact the price. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. The trading in FLEX Options may be less deep and liquid than the market for certain other exchange-traded options, non-customized options or other securities. The Fund also is subject to the risk that the OCC will become insolvent or otherwise be unable to meet its obligations, which could cause the Fund to suffer losses which may be significant. The Fund may not experience substantial upside participation from specific FLEX Option positions and certain FLEX Option positions may expire worthless. OCC may base its calculations of the margin requirements for positions in a series of FLEX Options on an estimate derived from data and factors OCC deems pertinent in respect of quotations and transactions in that options series and in other options series. Alternatively, OCC may fix such margin requirements at a level it deems necessary to protect the respective interests of OCC, the clearing members and the public. As a result, the Fund's margin requirements for positions in FLEX Options may differ from — and may be significantly greater than — the margin requirements applicable to similar positions in other options on the same underlying interest. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Box Spread Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Box Spread Risk — If one or more of the individual option positions that comprise a Box Spread are modified or closed separately prior to the option contract's expiration, then the Box Spread may no longer effectively eliminate risk tied to underlying reference asset's price movement. Furthermore, the Box Spread's value is derived in the market and is in part based on the time until the options comprising the Box Spread expire and the prevailing market interest rates. The Fund's ability to utilize Box Spreads effectively is dependent on the availability and willingness of other market participants to sell Box Spreads to the Fund at competitive prices. If the Box Spread does not perform as intended, the Fund could have exposure to the underlying reference asset of the options comprising the Box Spread, which is expected to be the SPY or SPX. In such a scenario, the Fund would be subject to the risks of equity securities markets. Equity securities prices fluctuate for several reasons, including changes in investors' perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Interest Rate Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Interest Rate Risk — Interest rate risk is the risk that the value of the debt securities in the Fund's portfolio will decline because of rising market interest rates. Interest rate risk is generally lower for shorter term debt securities and higher for longer term debt securities. Duration is a measure of the expected price volatility of a debt security as a result of changes in market rates of interest, based on, among other factors, the weighted average timing of the debt security's expected principal and interest payments. Prices of debt securities with shorter durations tend to be less sensitive to interest rate changes than debt securities with longer durations. As the value of a debt security changes over time, so will its duration. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Investment in a Subsidiary [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment in a Subsidiary — As determined necessary or advisable by the Fund, the Fund may invest a portion of its assets in a wholly-owned subsidiary (a "Subsidiary"), organized under the laws of the Cayman Islands. Investment in the Subsidiary is expected to provide the Fund with exposure to Spot bitcoin within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and Internal Revenue Service guidance. The Subsidiary may invest primarily in derivative instruments, including options on the Underlying ETPs and/or Bitcoin Index. The Fund does not intend to create or acquire primary control of any entity which engages in investment activities in securities or other assets other than entities wholly owned or majority-owned by the Fund. To the extent that a Fund invests in the Subsidiary, the Fund may be subject to the risks associated with the above-mentioned derivative instruments and other securities, which are discussed elsewhere herein and the SAI. To comply with the asset diversification test applicable to a RIC (discussed elsewhere in this prospectus), the Fund intends to limit its investments in such subsidiary to 25% of the Fund's total assets at the end of each taxable quarter. Although the Subsidiary may be considered similar to investment companies, it is not registered under the 1940 Act and, unless otherwise noted in each Fund's Prospectus and SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. The Board of Trustees, however, has oversight responsibility for the investment activities of each Fund, including its investment in its respective subsidiary. In addition, each Fund is the sole shareholder of its respective Subsidiary, and it is not currently expected that shares of a Subsidiary will be sold or offered to other investors. The Fund will treat a Subsidiary's assets as assets of the Fund for purposes of determining compliance with various provisions of the 1940 Act applicable to the Fund, including those relating to investment policies for purposes of Section 8, capital structure so that the Fund treats the debt of the Subsidiary as its own for purposes of Sections 18, and affiliated transactions and custody for purposes of Sections 17. The Advisor to the Subsidiary complies with the provisions of Section 15 of the 1940 Act as an investment adviser to the Fund, as defined in Section 2(a)(20) of the 1940 Act. The Subsidiary and its board agree to designate an agent for service of process in the United States. The Subsidiary's custodian is State Street Bank and Trust Company. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of a Fund and/or a Subsidiary to operate as described in the Fund's Prospectus and SAI and could negatively affect a Fund and its shareholders. The Advisor also serves as the investment adviser to the Subsidiary but will not receive separate compensation for services provided to the subsidiary. |

| Prospectus [Line Items] | |
| Risk [Text Block] | • Investment Timing Risk — An investor who purchases Fund Shares other than on the first day of the options package and/or sells Fund Shares before the options package expires may not experience the 80% downside protection or upside participation in the price of Spot bitcoin as reflected through investment in one or more Underlying ETPs and/or Bitcoin Index. The Fund's downside protection and upside participation of the price of Spot bitcoin may only be available for investors who hold Fund Shares throughout the complete term of the options package. An investor can expect their Fund Shares to move generally in the same direction as the Underlying ETPs and/or Bitcoin Index during the approximately twelve (12) months options package. However, Fund Shares may not experience the same price movement as the price movement of the price of Spot bitcoin. During the duration of the option package, there may be periods of significant disparity between the Fund's NAV and the Underlying ETPs and/or Bitcoin Index price performance. For example, if an investor purchases Fund Shares during an options package period at a time when the Spot bitcoin price (as measured by the BRRNY) has increased from its price at the beginning of the options package period, the investor may not be 80% protected against the Spot bitcoin's downside losses. In addition, if an investor purchases Fund Shares during an options package period at a time when the price of Spot bitcoin has increased from its price at the beginning of the options package period, that investor's cap will essentially be decreased from the stated Cap by the amount of the increase in Spot bitcoin's value. |

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Liquidity Risk — FLEX Options [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Liquidity Risk — FLEX Options — If and when available, in the event that trading in the underlying FLEX Options is limited or absent, the value of the Fund's FLEX Options may decrease. There is no guarantee that a liquid secondary trading market will exist for the FLEX Options. The trading in FLEX Options may be less deep and liquid than the market for certain other securities, including certain non-customized option contracts. In a less liquid market for the FLEX Options, terminating the FLEX Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of FLEX Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its FLEX Option positions. A less liquid trading market may adversely impact the value of the FLEX Options and the value of your investment. |

The trading in Listed Options may be less deep and liquid than the market for certain other exchange traded option contracts. In a less liquid market for the Listed Options terminating the Listed Options may require the payment of a premium or acceptance of a discounted price and may take longer to complete. Additionally, the liquidation of a large number of Listed Options may more significantly impact the price in a less liquid market. Further, the Fund requires a sufficient number of participants to facilitate the purchase and sale of options on an exchange to provide liquidity to the Fund for its Listed Option positions.

| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Management Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Management Risk — Investment decisions will be made for the Fund by the Advisor. The Fund is subject to management risk because, in relying on the Advisor to achieve its investment objective, it runs the risk that the Advisor's investment techniques will fail to produce intended results and that this may cause the Fund to incur significant losses. Purchasing and selling options are highly specialized activities and entail higher risks than simply purchasing and selling publicly traded securities. The Advisor may fail to use options effectively and options purchased or sold by the Fund may fail to perform as expected by the Advisor. The Fund's success will depend in part on the Advisor's ability to correctly predict the rates of return and risks of the options that it sells or buys |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Market Maker Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Maker Risk — If the Fund has lower average daily trading volumes, it may rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund's net asset value and the price at which the Fund Shares are trading on the Exchange, which could result in a decrease in value of the Fund Shares. In addition, decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund's portfolio securities and the Fund's market price. This reduced effectiveness could result in Fund Shares trading at a discount to net asset value and also in greater than normal intra-day bid-ask spreads for Fund Shares. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Market Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Market Risk — The risk that the securities markets will increase or decrease in value is considered market risk and applies to any security. If there is a general decline in the stock or fixed-income market, it is possible your investment may lose value regardless of the individual results of the companies in which the Fund invests. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | New Fund Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • New Fund Risk — The Fund is a recently organized investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Options Risk — The market price of an option is affected by many factors, including changes in the market prices or dividend rates of underlying securities (or in the case of indices, the securities in those indices); the time remaining before expiration; changes in interest rates or exchange rates; and changes in the actual or perceived volatility of the relevant index and underlying securities. The market price of an option also may be adversely affected if the market for the option becomes less liquid. The Fund's ability to close out its position as a purchaser or seller of an over-the-counter or exchange-listed call option is dependent, in part, upon the liquidity of the options market. An exchange-traded option may be closed out by means of an offsetting transaction only on a national securities exchange, which provides a secondary market for an option of the same series. If a liquid secondary market for an exchange-traded option does not exist, a Fund will not be able to effect an offsetting closing transaction for a particular option. Reasons for the absence of a liquid secondary market on a national securities exchange include the following: (i) insufficient trading interest in some options; (ii) restrictions by an exchange on opening or closing transactions, or both; (iii) trading halts, suspensions, or other restrictions on particular classes or series of options or underlying securities; (iv) unusual or unforeseen interruptions in normal operations on an exchange; (v) inability to handle current trading volume; or (vi) discontinuance of options trading (or trading in a particular class or series of options). In addition, the hours of trading for options on an exchange may not conform to the hours of trading of the underlying securities, creating a risk of significant changes in the prices of underlying securities that are not immediately reflected in the options markets. There are significant differences between the securities and options markets that could result in an imperfect correlation among these markets, causing a given transaction not to achieve its objectives. The Fund's ability to utilize options successfully will depend on the ability of the Fund's investment adviser to predict pertinent market movements, which cannot be assured. Until FLEX Options and/or Listed Options become available, the Fund will purchase and sell OTC Options, which involves risks different from, and possibly greater than, the risks associated with exchange-listed call options. OTC Options may expose the Fund to the risk that a counterparty may be unable or unwilling to perform according to a contract, and that any deterioration in a counterparty's creditworthiness could adversely affect the instrument. In addition, the Fund may be exposed to a risk that losses may exceed the amount originally invested. The holder of an option may terminate its position in a call option it has purchased by allowing it to expire or by exercising the option. If an option is European style, it may be exercised only on its expiration date. If the option is American style, it may be exercised on any day up to and including its expiration date. While the Fund expects to enter into European style options that are exercisable at the strike price only on the expiration date at the end of an Outcome Period, it may enter into American style options from time to time. When the Fund writes an American style option, it has no control over when it will be required to fulfill its obligations and there is risk that a counterparty will exercise the option at a time that is not advantageous to the Fund. If an American style option is exercised, the Fund may close out the corresponding purchased option and enter into new put and call options. There can be no guarantee that a Fund will be able to effect a closing purchase or a closing sale with respect to a specific option at any particular time or that the Fund will not suffer losses as a result of a written option being exercised prior to the end of an Outcome Period. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | OTC Options Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • OTC Options Risk — Unless the parties provide for it, there is no central clearing or guaranty function in an OTC Option. As a result, if the Counterparty fails to make or take delivery of the Underlying ETPs underlying an OTC Option it has entered into with the Fund or fails to make a cash settlement payment due in accordance with the terms of that option, the Fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, the Advisor must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC Option will be satisfied. The Advisor's assessment of any Counterparty may be inaccurate or incomplete and is subject to considerable judgment, which may be incorrect. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Position Limits Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Position Limits Risk — The options exchanges have established limits on the maximum number of puts and calls covering the same underlying security that may be held or written by a single investor or group of investors acting in concert or under common control (regardless of whether the options are purchased or written on the same or different exchanges or are held or written in one or more accounts or through one or more brokers). These are referred to as "position limits." The position limit applicable to a particular option class is determined by the options exchange based on the number of shares outstanding and trading volume of the security underlying the option. The rules of the options markets generally limit the maximum number of options on the same side of the market (i.e., calls held plus puts written, or puts held plus calls written) with respect to a single underlying interest that may be carried in the accounts of a single investor or group of investors acting in concert. An options market may require that positions in certain Listed Options or FLEX Options be aggregated with positions in certain other options for purposes of calculating position limits. The clearing members that clear the Fund's listed option positions are required to monitor and report the Fund's positions to the options exchanges and may be required to liquidate positions in excess of these limits. Failure to comply with position limits may result in the imposition of fines and other sanctions by the options exchanges. Even if a Fund does not intend to exceed applicable position limits, it is possible that different clients managed by the Advisor and its affiliates may be aggregated. Therefore, the trading decisions of the Advisor may have to be modified and positions held by a Fund liquidated in order to avoid exceeding such limits. The modification of investment decisions or the elimination of open positions, if it occurs, may adversely affect the profitability of a Fund and prevent the Fund from achieving its investment objective. A violation of position limits could also lead to regulatory action materially adverse to a Fund's investment strategy. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Premium-Discount Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Premium-Discount Risk — Fund Shares may trade above or below their NAV. The market prices of Fund Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Fund Shares on the Exchange. The trading price of Fund Shares may deviate significantly from NAV during periods of market volatility. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Secondary Market Trading Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Secondary Market Trading Risk — Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. Although the Fund Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Fund Shares on the Exchange may be halted. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Sector Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Sector Risk — To the extent the Underlying ETPs invest a significant portion of their assets in a particular sector, a greater portion of the Fund's performance may be affected by the general business and economic conditions affecting that sector. Each sector may share economic risk with the broader market, however there may be economic risks specific to each sector. As a result, returns from those sectors may trail returns from the overall stock market, and it is possible that one or more, if not all of the Underlying ETPs may underperform the broader market, or experience greater volatility. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Tax Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] |
• Tax Risk — The Fund intends to elect and to qualify each year to be treated as a regulated investment company ("RIC") under Subchapter M of the Code. The federal income tax treatment of certain aspects of the Fund's operations — including its option strategy, its hedging strategy, and the possible application of the "straddle" rules and various loss limitations — is not entirely clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult to comply with the tax requirements applicable to RICs if the tax characterization of investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. Any such failure to comply with the rules applicable to RICs could cause the Fund to fail to qualify as such. To qualify and maintain its status as a RIC, the Fund must derive at least 90% of its gross income each year from "qualifying income," meet certain diversification tests at the end of each quarter and meet an annual distribution test. For purposes of the qualifying income requirement, the treatment of derivatives that provide exposure to the Underlying ETPs or bitcoin is not entirely clear, and thus whether the income and gain therefrom is qualifying income is uncertain. If the Fund were to treat income or gain from particular instruments linked to bitcoin as qualifying income, an adverse determination or future guidance by the Internal Revenue Service with respect to the treatment of income or gain from those investments may adversely affect the Fund's ability to qualify as a RIC. For purposes of the diversification tests, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In particular, there is no published Internal Revenue Service guidance or case law on how to determine the "issuer" of certain derivatives that the Fund will enter into. The Underlying ETPs are expected to be treated as the issuer of certain of the Fund's investments, which may make it more difficult for the Fund to meet the diversification tests. In addition, an adverse determination or future guidance by the Internal Revenue Service with respect to issuer identification for the Fund's investments may adversely affect the Fund's ability to qualify as a RIC. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund's taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. The Fund's investments in offsetting positions with respect to the Underlying ETPs may affect the character of gains or losses realized by the Fund under the Code's "straddle" rules and may increase the amount of short-term capital gain realized by the Fund. The federal income tax treatment of options comprising the Box Spreads and of other derivatives may not be as favorable as a direct investment in an underlying asset and may adversely affect the timing, character and amount of income the Fund realizes from its investments. As a result, a larger portion of the Fund's distributions may be treated as ordinary income rather than capital gains. In addition, certain derivatives are subject to mark-to-market or straddle provisions of the Code. If such provisions are applicable, there could be an increase (or decrease) in the amount of taxable dividends paid by the Fund. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Trading Issues Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Trading Issues Risk — Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. The Fund may have difficulty maintaining its listing on the Exchange in the event the Fund's assets are small, the Fund does not have enough shareholders, or if the Fund is unable to proceed with creation and/or redemption orders. |

| Risk [Text Block] | • U.S. Government Security Risk — Some securities issued by U.S. Government agencies or government-sponsored enterprises are not backed by the full faith and credit of the U.S. and may only be supported by the right of the agency or enterprise to borrow from the U.S. Treasury. There can be no assurance that the U.S. Government will always provide financial support to those agencies or enterprises. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | U.S. Treasury Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • U.S. Treasury Risk — A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity, but the market prices for such securities are not guaranteed and will fluctuate. Because U.S. Treasury securities trade actively outside the United States, their prices may rise and fall as changes in global economic conditions affect the demand for these securities. U.S. Treasury securities may differ from other securities in their interest rates, maturities, times of issuance and other characteristics, and may provide relatively lower returns than those of other securities. Similar to other issuers, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund's U.S. Treasury securities to decline. U.S. Treasury securities are subject to interest rate risk, but generally do not involve the credit risks associated with investments in other types of debt securities. As a result, the yields available from U.S. government securities are generally lower than the yields available from other debt securities. |
| Calamos Bitcoin 80 Series Structured Alt Protection ETF - October | Valuation Risk [Member] | |
| Prospectus [Line Items] | |
| Risk [Text Block] | • Valuation Risk — During periods of reduced market liquidity or in the absence of readily available market quotations for the holdings of the Fund, the ability of the Fund to value the OTC Options, FLEX Options and Listed Options may become more difficult. In market environments where there is reduced availability of reliable objective pricing data, the judgment of the Advisor in determining the fair value of the security may play a greater role. While such determinations may be made in good faith, it may nevertheless be more difficult for the Fund to accurately assign a daily value. |
