Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and the Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).
Consolidation	The condensed consolidated financial statements include the consolidated accounts of the Company’s majority-owned subsidiary, ADK LLC, of which 82% was owned by indie as of June 30, 2022. ADK LLC’s consolidated financial statements include its wholly-owned subsidiaries Indie Services Corporation, indie LLC and Indie City LLC, all California entities, Ay Dee Kay Limited, a private limited company incorporated under the laws of Scotland, indie GmbH, a private limited liability company incorporated under the laws of Germany, indie Kft, a limited liability company incorporated under the laws of Hungary, TeraXion Inc., a company incorporated under the laws of Canada, indie Semiconductor Israel Ltd., a private limited company incorporated under the laws of Israel, Wuxi indie Microelectronics (“Wuxi”), a Chinese entity with 64% voting controlled and 44% owned by the Company as of June 30, 2022 and Wuxi’s wholly-owned subsidiaries, indie Semiconductor Japan, indie Semiconductor HK, Ltd and Shanghai Ziying Microelectronics Co., Ltd.All significant intercompany accounts and transactions of the subsidiaries have been eliminated in consolidation. The noncontrolling interest attributable to the Company’s less-than-wholly-owned subsidiary is presented as a separate component from stockholders’ equity (deficit) in the consolidated balance sheets, and a noncontrolling interest in the consolidated statements of operations and consolidated statements of stockholders’ equity (deficit) and noncontrolling interest.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB amended guidance related to impairment of financial instruments as part of ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss impairment methodology with an expected credit loss model for which a company recognizes an allowance based on the estimate of expected credit loss. This ASU requires entities to measure the impairment of certain financial instruments, including accounts receivable, based on expected losses rather than incurred losses. This ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted, and will be effective for the Company beginning in 2023. The Company is currently evaluating the impact of the new standard on the Company’s condensed consolidated financial statements and related disclosures. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”), whereby lessees will be required to recognize for all leases at the commencement date a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use (“ROU”) asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. A modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements must be applied. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. The FASB issued ASU 2019-10-Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates in November 2019 and ASU 2020-05-Revenue from Contracts with Customers (Topic 606) and Leases (Topic 842): Effective Dates for Certain Entities in June 2020. The ASUs change some effective dates for ASU 2016-02 on leasing. After applying ASU 2019-10 and 2020-05, ASU 2016-02 is effective for annual periods beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2021. The Company applied the transition requirements on the adoption date of January 1, 2022, rather than at the beginning of the earliest comparative period presented. This approach allows for a cumulative effect adjustment in the period of adoption, and prior periods will not be restated. In addition, the Company elected the package of practical expedients permitted under the transition guidance, which does not require reassessment of prior conclusions related to contracts containing a lease, lease classification and initial direct lease costs. The Company also elected to use the hindsight practical expedient to consider any facts or circumstances that have changed through the January 1, 2022 adoption date that may affect the lease term due to renewal options and assess the impairment of the right-of-use asset. As an accounting policy election, the Company also excluded short-term leases (term of 12 months or less) from the balance sheet presentation and accounted for non-lease and lease components in a contract as a single lease component for certain asset classes. Effective January 1, 2022, the Company recorded the impact on its condensed consolidated balance sheet from the recognition of ROU asset and lease liability of $10,344. The impact to its condensed consolidated statements of operations, condensed consolidated statements of comprehensive income (loss) and condensed consolidated statements of cash flows is not material. See Note 16, Leases, for additional details. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles of ASC 740, Income Taxes. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020 (and December 15, 2021 for nonpublic companies) and early adoption is permitted. Depending on the amendment, adoption may be applied on a retrospective, modified retrospective, or prospective basis. The Company adopted ASU 2019-12 as of January 1, 2022 on a prospective basis. The standard had no material impact on the Company’s condensed consolidated financial statements and related disclosures. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the guidance on the issuer’s accounting for convertible debt instruments by removing the separation models for (1) convertible debt with a cash conversion feature and (2) convertible instruments with a beneficial conversion feature. As a result, entities will not separately present in equity an embedded conversion feature in such debt. Instead, they will account for a convertible debt instrument wholly as debt, unless certain other conditions are met. The elimination of these models will reduce reported interest expense and increase reported net income for entities that have issued a convertible instrument that was within the scope of those models before the adoption of ASU 2020-06. Also, ASU 2020-06 requires the application of the if-converted method for calculating diluted earnings per share and treasury stock method will be no longer available. The provisions of ASU 2020-06 are applicable for fiscal years beginning after December 15, 2021, with early adoption permitted no earlier than fiscal years beginning after December 15, 2020. The Company early adopted this update on January 1, 2022 using the modified retrospective method of transition and the impact to its condensed consolidated financial statements was not material.
