Summary of Significant Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC. Liquidity The Company’s liquidity needs up to December 31, 2025 had been satisfied through the loan under an unsecured promissory note from Art Technology Sponsor, LLC of up to $300,000. On January 7, 2026, the Company repaid the total outstanding balance of the Promissory Note amounting to $194,453 (see Note 5 and Note 9). As of December 31, 2025, the Company had no cash and a working capital deficit of $351,878. Subsequent to the balance sheet date covered by this annual report, on January 7, 2026, the Company consummated the Initial Public Offering of 22,000,000 Units at $10.00 per Unit, generating gross proceeds of $220,000,000. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 825,000 Private Placement Units at a price of $10.00 per Private Placement Unit, in a private placement to the Sponsor and Clear Street, generating gross proceeds of $8,250,000. As a result of the Initial Public Offering, as of January 7, 2026, the Company had cash of $3,112,042 and working capital of $2,893,382 after depositing $220,000,000 into the Trust Account. In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but is not obligated to, loan the Company funds as may be required (the “Working Capital Loans”). If the Company completes a Business Combination, the Company would repay such loaned amounts at that time. Up to $2,500,000 of such Working Capital Loans may be converted into private placement units upon consummation of the Business Combination at a price of $10.00 per unit. The units would be identical to the Private Placement Units. As of December 31, 2025, the Company had no borrowings under the Working Capital Loans. Prior to the completion of the Initial Public Offering and the full exercise by the underwriters of their over-allotment option, the Company lacked the liquidity it needed to sustain operations for a reasonable period of time, which is considered to be one year from the issuance date of the financial statements. In connection with the Company’s assessment of going concern considerations in accordance with ASC 205-40, “Presentation of Financial Statements - Going Concern,” the Company has completed its Initial Public Offering and the full exercise by the underwriters of their overallotment option, at which time the capital in excess of the funds deposited in Trust Account and used to fund offering expenses was released to the Company for general capital purposes. The Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating its business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the initial Business Combination. The Company has the duration of the Combination Period to complete the initial Business Combination. Management has determined that the Company has sufficient funds to finance the working capital needs of the Company within one year from the date of issuance of the financial statements. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Use of Estimates The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash and cash equivalents as of December 31, 2025. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows. Deferred Offering Costs The Company complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. FASB ASC 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between Class A ordinary shares and warrants, allocating the Initial Public Offering proceeds to the assigned value of the warrants and to the Class A ordinary shares. On January 7, 2026, offering costs allocated to the Public Shares were charged to temporary equity, and offering costs allocated to the Public Warrants and Private Placement Units were charged to shareholder’s deficit as Public Warrants and Placement Warrants after management’s evaluation were accounted for under equity treatment. Income Taxes The Company accounts for income taxes under FASB ASC Topic 740, “Income Taxes,” which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. FASB ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of December 31, 2025, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented. Fair Value of Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC 820, “Fair Value Measurement,” approximates the carrying amounts represented in the balance sheet, primarily due to their short-term nature. Net Loss per Class B Ordinary Share Net loss per Class B ordinary share is computed by dividing net loss by the weighted average number of Class B ordinary shares outstanding during the period, excluding Class B ordinary shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 1,100,000 Class B ordinary shares that were subject to forfeiture if the over-allotment option was not exercised by the underwriters (see Note 5). For the period from August 22, 2025 (inception) through December 31, 2025, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into Class B ordinary shares and then share in the earnings of the Company. As a result, diluted loss per Class B ordinary share is the same as basic loss per Class B ordinary share for the period presented. Warrant Instruments The Company accounted for the Public Warrants and Placement Warrants issued in connection with the Initial Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at their assigned values. Such guidance provides that the warrants described above will not be precluded from equity classification. Equity-classified contracts are initially measured at fair value (or allocated value). Subsequent changes in fair value are not recognized as long as the contracts continue to be classified in equity in accordance with ASC 480 and ASC 815. Recent Accounting Standards Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying financial statements are presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC.
