Accounting Policies [Abstract]
Description of Business and Significant Accounting Policies	Description of Business and Significant Accounting Policies Description of Business Upstart Holdings, Inc. and its subsidiaries (together “Upstart,” the “Company,” “we,” or “our”) apply artificial intelligence models and cloud applications to the process of underwriting consumer credit. The Company helps originate credit by providing lending partners with access to a proprietary, cloud-based, artificial intelligence lending marketplace. As the Company’s technology continues to improve and additional lending partners adopt the Upstart platform, consumers benefit from improved access to affordable and frictionless credit. The Company currently operates in the United States and is headquartered in San Mateo, California. The Company’s fiscal year ends on December 31. Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements included in our Annual Report on Form 10-K. Certain prior period amounts have been reclassified where appropriate to conform to the current period presentation of such amounts. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary to state fairly the Company’s financial position, results of operations, comprehensive income (loss) and cash flows for the periods presented, but are not necessarily indicative of the results of operations to be anticipated of any future annual or interim periods. Certain information and disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been omitted pursuant to rules and regulations of the SEC. Accordingly, the information included in this Quarterly Report on Form 10-Q/A should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2024. Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires that management 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates and assumptions made in the accompanying condensed consolidated financial statements, which management believes are critical in understanding and evaluating the Company’s reported financial results include: (i) fair value determinations; (ii) stock-based compensation; (iii) consolidation of VIEs; and (iv) the evaluation for impairment of goodwill. The Company bases its estimates on various factors it believes to be reasonable under the circumstances. Actual results could differ from those estimates and such differences could affect the results of operations reported in future periods. Recently Adopted Accounting Pronouncements On January 1, 2025, the Company adopted Accounting Standards Update (“ASU”) 2023-08, Intangibles—Goodwill and Other—Crypto Assets (Subtopic 350-60): Accounting for and Disclosure of Crypto Assets. The new guidance requires certain crypto assets to be measured at fair value with changes in fair value recorded in net income, and additional disclosures about the holdings of certain crypto assets. The adoption of the new standard did not have an impact on the Company’s condensed consolidated financial statements or related disclosures. Recently Issued Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this update require entities to disclose specific categories in the effective tax rate reconciliation and provide additional information for reconciling items where the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income/loss by the applicable statutory income tax rate. In addition, entities are required to disclose the year-to-date amount of income taxes paid (net of refunds received) disaggregated by jurisdictions. This ASU is effective for annual periods beginning after December 15, 2024 with early adoption permitted. The Company is currently evaluating the impact of these amendments to its condensed consolidated financial statements and related disclosures and plans to include the additional required disclosures relating to income taxes beginning in our Annual Report on Form 10-K for the fiscal year ending December 31, 2025. In November 2024, the FASB issued ASU 2024-03 and subsequently ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments in this update require disaggregated disclosures in the notes to the financial statements for certain expenses such as employee compensation, depreciation, and intangible asset amortization, which are commonly presented in aggregate. This ASU is effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027 with early adoption permitted. The Company is currently evaluating the impact of these amendments to its condensed consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-04, Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments. The amendments in this update clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. This ASU is effective for annual reporting periods beginning after December 15, 2025 with early adoption permitted. The Company is currently evaluating the impact of these amendments to its condensed consolidated financial statements and related disclosures.
