Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial reporting. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Articles 8 and 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, it does not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. The information herein should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which was filed on March 24, 2025. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair statement of the financial position, operating results, and cash flows for the periods presented. Segment Information The Company has viewed its financial information on an aggregate basis for the purposes of evaluating financial performance and allocating the Company’s resources. The Company's principal business consists primarily of research and development activities for its planned powerhouses, radioisotopes business and nuclear recycling facilities. Accordingly, the Company has determined that it operates in one reportable segment. For more information about the Company's single operating and reportable segment, see Note 13. Principles of Consolidation The condensed consolidated financial statements include the Company’s accounts and those of its wholly owned subsidiaries Oklo Technologies, Inc., Atomic Alchemy, Inc., and Oklo Power LLC. All intercompany transactions and balances have been eliminated. Use of Estimates Preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments, and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from these estimates. On an ongoing basis, the Company evaluates its estimates, including those related to the valuation of the operating lease liabilities and operating right-of-use assets, useful lives of property and equipment, stock-based compensation expense, valuation allowance on deferred tax assets, and fair value of acquired intangible assets and goodwill. These estimates, judgments, and assumptions are based on current and expected economic conditions, historical data, and experience available at the date of the accompanying condensed consolidated financial statements, and various other factors that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Risk and Uncertainties The Company is subject to continuing risks and uncertainties in connection with the current macroeconomic environment, including as a result of inflation, instability in the global banking system, trade policy (including tariffs, export controls, and sanctions), and geopolitical factors, including the ongoing conflicts in Ukraine and Israel. At this point, the extent to which these effects may impact the Company’s future financial condition or results of operations is uncertain, and as of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require the update of any estimates or judgments or an adjustment of the carrying value of any assets or liabilities. Given the nature of the business, the ongoing conflicts in Ukraine and Israel have not had a specific impact on the Company’s financial performance. These estimates may change as new events occur and additional information is obtained and will be recognized in the financial statements as soon as they become known. Net Loss Per Common Share The Company’s basic net loss per share of common stock is computed based on the average number of outstanding shares of common stock for the period, by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period, without consideration for potential dilutive securities. Diluted net loss per share of common stock is computed by dividing net loss by the weighted-average number of shares of common stock and common share equivalents of potentially dilutive securities outstanding for the period. Potentially dilutive securities include common stock equivalents. Since the Company was in a loss position for the periods presented, basic net loss per share of common stock is the same as diluted net loss per share of common stock since the effects of potentially dilutive securities are antidilutive. The outstanding potentially dilutive common stock equivalents for: (1) options to purchase shares of common stock of 9,151,461 and 10,432,749 as of March 31, 2025 and 2024, respectively, (2) unvested restricted stock of 640,125 and 0, and (3) unvested restricted stock units of 1,624,743 and 0, respectively, have been excluded from the calculation of diluted net loss per common share due to their anti-dilutive effect. Emerging Growth Company Status The Company is an emerging growth company ("EGC") as defined in the Jumpstart Our Business Startups Act (“JOBS Act”). The JOBS Act provides emerging growth companies with certain exemptions from public company reporting requirements for up to five fiscal years while a company remains an emerging growth company. As part of these exemptions, the Company has reduced disclosure obligations such as for executive compensation, and it is not required to comply with auditor attestation requirements from Section 404(b) of the Sarbanes-Oxley Act of 2002, as amended, regarding its internal control over financial reporting. Additionally, the JOBS Act has allowed the Company the option to delay adoption of new or revised financial accounting standards until private companies are required to comply with new or revised financial accounting standards. The Company's EGC status is expected to expire on December 31, 2026, although this could occur earlier if the Company fails to meet the required EGC qualifications. The Company will perform an annual assessment as of June 30, 2025 to determine ongoing eligibility for EGC status. Indefinite-Lived Intangible Assets Intangible assets with indefinite lives consist of in-process research and development (“IPR&D”) from the Company's acquisition of Atomic Alchemy (further details are provided under the heading Atomic Alchemy in Note 3). These assets are tested annually for impairment until completion. If potential impairment is identified, the process of evaluating the potential impairment of these assets involves significant judgment regarding estimates of the future cash flows associated with each asset. Goodwill Goodwill represents the excess purchase consideration of an acquired business over the estimated fair value of the net assets acquired and is not amortized. Goodwill is evaluated for impairment annually, or whenever events or circumstances indicate that the carrying amount may not be recoverable. If the carrying amount of the Company's reportable segment exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reportable segment's goodwill over the implied fair value of the goodwill. Recently Issued and Not Adopted Accounting Standards In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which will require the Company to disclose specified additional information in its income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. ASU 2023-09 will also require the Company to disaggregate its income taxes paid disclosure by federal, state and foreign taxes, with further disaggregation required for significant individual jurisdictions. The provisions of ASU 2023-09 are effective for annual periods beginning after December 15, 2024; early adoption is permitted using either a prospective or retrospective transition method. The Company expects ASU 2023-09 to require additional disclosures in the notes to its condensed consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which will require disaggregated disclosures in the notes to the financial statements of certain categories of expenses, including purchases of inventory, employee compensation, and depreciation and amortization, that are included in expense line items within the statement of operations. ASU 2024-03 will be applied prospectively; however, retrospective application is permitted. ASU 2024-03, as clarified in ASU 2025-01, Clarifying the Effective Date, requires public business entities to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is evaluating the impact of ASU 2024-03 on its disclosures in the notes to its financial statements.
