Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The Company’s condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) as determined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”). Unaudited Interim Financial Statements The condensed consolidated balance sheet as of September 30, 2021, the condensed consolidated statements of operations and the condensed consolidated statements of changes in temporary equity and stockholders’ equity (deficit) for the three-months and nine-months ended September 30, 2021 and 2020, and the condensed consolidated statements of cash flows for the nine-months ended September 30, 2021 and 2020, as well as other information disclosed in the accompanying notes, are unaudited. The consolidated balance sheet as of December 31, 2020 was derived from the audited consolidated financial statements as of that date. The interim condensed consolidated financial statements and the accompanying notes should be read in conjunction with the annual consolidated financial statements and the accompanying notes contained in our Annual Report on Form 10-K/A Comprehensive loss is not separately presented as the amounts are equal to net loss for the three-months and nine-months ended September 30, 2021 and 2020. The interim condensed consolidated financial statements and the accompanying notes have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The condensed consolidated financial statements for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future years or interim periods. Reverse Recapitalization The Business Combination was accounted for as a reverse recapitalization and Spartan was treated as the “acquired” company for accounting purposes. The Business Combination was accounted as the equivalent of Legacy Fisker issuing stock for the net assets of Spartan, accompanied by a recapitalization. Accordingly, all historical financial information presented in these consolidated financial statements represents the accounts of Legacy Fisker and its wholly owned subsidiaries “as if” Legacy Fisker is the predecessor to the Company. The shares and net loss per common share, prior to the Business Combination, have been adjusted as shares reflecting the exchange ratio established in the Business Combination. Going Concern, Liquidity and Capital Resources The Company evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern over the next twelve months from the date of filing this report. Since inception, the Company has incurred significant accumulated losses of approximately $481 million. As of September 30, 2021, the Company had approximately $1,400 million in cash and cash equivalents. The Company expects to continue to incur significant operating losses for the foreseeable future. Proceeds from the Business Combination, issuance of convertible senior notes, and exercised public warrants and options provide the Company the liquidity and capital resources to fund its operating expenses and capital expenditure requirements for at least the next 12 months from issuance. Supplier Risk The Company continued nomination of suppliers with an accelerated phase during the quarter for engineering, development, testing, tooling and production of components for serial production of its vehicles. As of September 30, 2021, these supplier contracts do not represent unconditional purchase obligations with take-or-pay Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP required management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the condensed consolidated financial statements and accompanying notes. The Company bases these estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates. Fair Value Measurements The Company follows the accounting guidance in ASC 820, Fair Value Measurement The accounting guidance requires fair value measurements be classified and disclosed in one of the following three categories: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Observable inputs other than Level 1 prices, for similar assets or liabilities that are directly or indirectly observable in the marketplace. Level 3: Unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Income Taxes Income taxes are recorded in accordance with ASC 740, Income Taxes There are transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. As of September 30, 2021, there were no material changes to either the nature or the amounts of the uncertain tax positions previously determined for the year ended December 31, 2020. The Company’s income tax provision consists of an estimate for U.S. federal and state income taxes based on enacted rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in deferred tax assets and liabilities, and changes in the tax law. The Company maintains a valuation allowance against the full value of its U.S. and state net deferred tax assets because the Company believes the recoverability of the tax assets is not more likely than not as of September 30, 2021. Debt issuance costs Direct and incremental costs, including amounts paid to initial purchasers of the Company’s convertible notes, are directly attributed to efforts to obtain debt financing are debt issuance costs. Upon issuance of debt, the carrying value is the principal amount of debt reduced by any debt issuance costs. Debt issuance costs are attributed to interest expense and accreted over the expected term of the debt using the effective interest rate method. Derivative Liability The Company accounts for its public and private warrants as a derivative liability initially measured at its fair values and remeasured in the condensed consolidated statements of operations at the end of each reporting period. When the warrants are exercised, the corresponding derivative liability is de-recognized Equity Awards The grant date for an option or stock award is established when the grantee has a mutual understanding of the key terms and conditions of the option or award, the award is authorized, including all the necessary approvals unless approval is essentially a formality or perfunctory, and the grantee begins to benefit from, or be adversely affected by, underlying changes in the price of the Company’s Class A common shares. An award or option is authorized on the date that all approval requirements are completed (e.g., action by the compensation committee approving the award and the number of options, restricted shares or other equity instruments to be issued to individual employees). Leases Current portion of the Company’s lease liability is based on lease payments due within twelve months of the balance sheet date. Variable lease payments are included in lease payments when the contingency upon which the payment is dependent is resolved. Net Loss per Share of Common Stock Basic net loss per share of common stock is calculated using the two-class Recently adopted accounting pronouncements In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes No. 2019-12 In September 2020, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) 815-40) if-converted 2020-06 2020-06, Recently issued accounting pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments available-for-sale non-public

Business Combination And Recapitalization Disclosure [Abstract]
Business Combination and Recapitalization	3. Business Combination and Recapitalization On October 29, 2020, the Company consummated (the “Closing”) the Business Combination with Legacy Fisker pursuant to the business combination agreement between Legacy Fisker and Spartan (the “Merger Agreement”). Pursuant to ASC 805, for financial accounting and reporting purposes, Legacy Fisker was deemed the accounting acquirer and the Company was treated as the accounting acquiree, and the Business Combination was accounted for as a reverse recapitalization. Accordingly, the Business Combination was treated as the equivalent of the Legacy Fisker issuing stock for the net assets of Spartan, accompanied by a recapitalization. The net assets of Spartan were stated at historical costs, with no goodwill or other intangible assets recorded, and are consolidated with Legacy Fisker’s financial statements on the date of the Closing. The shares and net income (loss) per share available to holders of the Company’s common stock, prior to the Business Combination, have been adjusted as shares reflecting the exchange ratio established in the Merger Agreement. In connection with the Business Combination, Spartan entered into subscription agreements with certain investors (the “PIPE Investors”), whereby pursuant to which it issued 50,000,000 shares of Class A common stock at $10.00 per share (the “PIPE Shares”) for an aggregate purchase price of $500.0 million (the “PIPE Financing”), which closed simultaneously with the consummation of the Business Combination. The aggregate consideration for the Business Combination and proceeds from the PIPE Financing was approximately $1.8 billion, consisting of 179,192,713 shares of common stock valued at $10.00 per share. The common stock consideration consists of (1) 46,838,585 shares of Legacy Fisker Class A common stock, including shares issuable in respect of vested equity awards of the Legacy Fisker and shares issued in respect of the Bridge notes and Convertible Equity Security, plus (2) 132,354,128 shares of Legacy Fisker Class B common stock. Conversion of Notes and Preferred Stock upon Recapitalization Upon the formation of Legacy Fisker in September 2016, HF Holdco LLC, an entity controlled by the Company’s Chief Executive Officer, and founder, and the Company’s Chief Financial Officer and Chief Operating Officer, and founder, advanced the Company $250,000 in the form of a demand note. In May 2020, in satisfaction of the advances made by HF Holdco LLC, the Company issued a bridge note payable to HF Holdco LLC with the principal sum of $250,000 and convertible into Class A Common Stock upon completion of the Business Combination and is no longer outstanding as of December 31, 2020. From July 2019 to September 2020, the Company entered into bridge note agreements with investors. Certain holders of the bridge notes were issued option agreements providing the holder with a non-binding The automatic exchange feature is the predominant settlement feature and the change of control feature within the bridge notes are embedded contingent put options that, collectively, are required to be bifurcated from the debt host and measured at fair value with changes in fair value recognized in earnings (see Note 4). After bifurcation of the embedded derivative, the initial carrying value of the bridge notes are accreted to their stated principal value over the contractual term of the bridge notes, using the effective interest method. The Company recognized approximately $0.2 million of accretion of debt discount from the issuance dates of the bridge notes through March 31, 2020, classified as Interest expense in the Condensed Consolidated Statement of Operations. The embedded derivative was eliminated upon the conversion of the bridge notes payable at the close of the Business Combination. In June 2020, the Company entered into an amendment to the note agreements with holders of the Company’s outstanding bridge notes to provide for amendments to the definition of the Next Equity Financing such that in the event of a Special Purpose Acquisition Company (“SPAC”) Transaction, as defined, prior to repayment or conversion in full of the note, immediately prior to such SPAC Transaction, the outstanding principal and any accrued but unpaid interest under the bridge notes would automatically convert into shares of Class A Common Stock of the Company (or, at the election of the Company, directly into proceeds paid to the holders of Class A Common Stock in connection with such SPAC Transaction) at a price per share that is 75% of the price per share of Class A Common Stock paid in such SPAC Transaction. Upon the Closing, the conversion feature upon a business combination was triggered for the bridge notes causing a conversion of the $10.0 million outstanding principal amount of these bridge notes at a specified price. The noteholders received 1,361,268 shares of Class A Common Stock of the Company as result of the conversion in connection with the Business Combination. Prior to the Closing, Fisker had shares of $0.00001 par value Series A, Series B, and Founders Convertible preferred stock outstanding. The shares of Series A and B preferred stock were convertible into shares of Class A Common Stock of Legacy Fisker based on a specified conversion price calculated by dividing the then-original issue price, as adjusted, for such share of preferred stock by the conversion price, as adjusted, in effect on the date the certificate is surrendered for conversion. Shares of Founders preferred stock, classified in equity, were convertible into Class B Common Stock determined by dividing $0.10, as adjusted, for such share of preferred stock by the conversion price, as adjusted, in effect on the date the certificate is surrendered for conversion. Upon the Closing, the outstanding shares of preferred stock were converted into common stock of the Company at 2.7162, the exchange ratio established in the Business Combination Agreement. Immediately after the Business Combination, Founders Convertible, Series A (pre-combination), (pre-combination)

Fair value measurements The Company’s financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used for such measurements were as follows (in thousands): Fair Value Measured as of September 30, 2021: Level 1 Level 2 Level 3 Total Assets included in: Money market funds included in cash and cash equivalents $ 1,394,181 $ — $ — $ 1,394,181 Total fair value $ 1,394,181 $ — $ — $ 1,394,181 Fair Value Measured as of December 31, 2020: Level 1 Level 2 Level 3 Total Assets included in: Money market funds included in cash and cash equivalents $ 987,728 $ — $ — $ 987,728 Total fair value $ 987,728 $ — $ — $ 987,728 Liabilities included in: Warrants liability $ 90,487 $ — $ 47,615 $ 138,102 Total fair value $ 90,487 $ — $ 47,615 $ 138,102 The fair value of the Company’s money market funds is determined using quoted market prices in active markets for identical assets. The carrying amounts included in the Condensed Consolidated Balance Sheets under Current assets approximate fair value because of the short maturity of these instruments. We carry the convertible senior notes at face value less the unamortized debt issuance costs on our consolidated balance sheets and present that fair value for disclosure purposes only. As of September 30, 2021, the fair value of the 2026 Notes was $649.1 million. The estimated fair value of the convertible notes, which are classified as Level 2 financial instruments, was determined based on the estimated or actual bid prices of the convertible notes in an over-the-counter The Company’s derivative liability for its private and public warrants are measured at fair value on a recurring basis. The private warrants fair value is determined based on significant inputs not observable in the market, which causes it to be classified as a Level 3 measurement within the fair value hierarchy. The valuation of the private warrants uses assumptions and estimates the Company believes would be made by a market participant in making the same valuation. The Company assess these assumptions and estimates on an on-going non-operating The reconciliation of changes in Level 3 during the nine-months ended September 30, 2021 is as follows: Balance as of December 31, 2020 $ 47,615 Change in fair value 63,526 Cashless exercise of warrants (111,141 ) Balance as of September 30, 2021 $ —

Warants [Abstract]
Warrants	8. Warrants Public and Private Warrants Upon the Closing, there were 18,400,000 public and 9,360,000 private warrants outstanding to purchase shares of the Company’s common stock that were issued by Spartan prior to the Business Combination. Each whole warrant entitles the registered holder to purchase one whole share of the Company’s Class A Common Stock at a price of $11.50 per share, subject to adjustment as discussed below, 30 days after the Closing, provided that the Company has an effective registration statement under the Securities Act covering the shares of Class A Common Stock issuable upon exercise of the warrants and a current prospectus relating to them is available and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of shares of Class A Common Stock. The warrants will expire five years after the completion of the Business Combination, or earlier upon redemption or liquidation. The Private Placement Warrants are identical to the Warrants, except that the Private Placement Warrants and the Class A common stock issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of an Initial Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be non-redeemable On March 19, 2021, the Company announced that it would redeem all of its outstanding warrants (the “Public Warrants”) to purchase shares of the Company’s Class A common stock, par value $0.00001 per share (the “Common Stock”), that were issued under the Warrant Agreement, dated August 9, 2018 (the “Warrant Agreement”), by and between the Company and Continental Stock Transfer & Trust Company, as warrant agent (the “Warrant Agent”), as part of the units sold in the Company’s initial public offering (the “IPO”), for a redemption price of $0.01 per Public Warrant (the “Redemption Price”), that remained outstanding at 5:00 p.m. New York City time on April 22, 2021 (the “Redemption Date”). The Private Placement Warrants were not subject to this redemption. In addition, in accordance with the Warrant Agreement, the Company’s board of directors elected to require that, upon delivery of the notice of redemption, all Public Warrants were to be exercised only on a “cashless basis.” Accordingly, holders could not exercise Public Warrants and receive Common Stock in exchange for payment in cash of the $11.50 per warrant exercise price. Instead, a holder exercising a Public Warrant was deemed to pay the $11.50 per warrant exercise price by the surrender of 0.5046 of a share of Common Stock that such holder would have been entitled to receive upon a cash exercise of a Public Warrant. Accordingly, by virtue of the cashless exercise of the Public Warrants, exercising warrant holders received 0.4954 of a share of Common Stock for each Public Warrant surrendered for exercise. For the unexercised 225,906 Public Warrants outstanding at the Redemption Date, the Company paid $2,259 to redeem the unexercised warrants in the second quarter of 2021. There are no Public Warrants outstanding as of September 30, 2021. During March 2021, the 9,360,000 warrants to purchase Common Stock that were originally issued under the Warrant Agreement in a private placement simultaneously with the IPO were exercised by the Company’s former sponsor on a cashless basis for 4,907,329 shares of Common Stock (4,452,671 shares of Common Stock surrendered) and are no longer outstanding. Since January 1, 2021, the Company has received cash proceeds of $89 million upon the exercise of 7,733,400 Public Warrants immediately prior to the announcement to redeem the Public Warrants. Public and private warrant exercise activity and underlying Common Stock issued or surrendered for the nine-months ended September 30, 2021, is: Public warrants Private warrants Total December 31, 2020 18,391,587 9,360,000 27,751,587 Shares issued for cash exercises (7,733,400 ) (7,733,400 ) Shares issued for cashless exercises (5,167,791 ) (4,907,329 ) (10,075,120 ) Shares surrendered upon cashless exercise (5,264,490 ) (4,452,671 ) (9,717,161 ) Shares redeemed by Company for cash (225,906 ) (225,906 ) September 30, 2021 — — — Cashless exercises of public and private warrants increased additional paid-in Magna Warrants On October 29, 2020, the Company granted Magna up to 19,474,454 warrants, each with an exercise price of $0.01, to acquire underlying shares of Class A common stock of Fisker, which represented approximately 6% ownership in Fisker on a fully diluted basis as of the grant date. The right to exercise vested warrants expires on October 29, 2030. The warrants are accounted for as an award issued to non-employees The cost upon achievement of each milestone is capitalized when it is probable that a milestone is met. The cost for awards to nonemployees is recognized in the same period and in the same manner as if the Company had paid cash for the goods or services. On June 12, 2021, Fisker Group Inc., a Delaware corporation, a wholly-owned subsidiary of Fisker Inc., entered into a detailed manufacturing agreement with Magna Steyr Fahrzeugtechnik AG & Co KG, a limited liability partnership established and existing under the laws of Austria, an affiliate of Magna, and achieved the second milestone resulting in $58 million non-cash paid-in-capital pre-serial

On or after June 15, 2026, the 2026 Notes are convertible at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Holders of the 2026 Notes who convert the 2026 Notes in connection with a make-whole fundamental change, as defined in the indenture governing the 2026 Notes, or in connection with a redemption may be entitled to an increase in the conversion rate. Additionally, in the event of a fundamental change, holders of the 2026 Notes may require us to repurchase all or a portion of the 2026 Notes at a price equal to 100% of the principal amount of 2026 Notes, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. We accounted for the issuance of the 2026 Notes as a single liability measured at its amortized cost, as no other embedded features require bifurcation and recognition as derivatives. As of September 30, 2021, the 2026 Notes consisted of the following: Principal $ 667,500 Unamortized debt issuance costs (8,371 ) Net carrying amount $ 659,129 Interest expense related to the amortization of debt issuance costs was $0.2 million for the three and nine months ended September 30, 2021. Contractual interest expense was $2 million for the three and nine months ended September 30, 2021. As of September 30, 2021, the if-converted Capped Call Transactions In connection with the offering of the 2026 Notes, we entered into the 2026 Capped Call Transactions with certain counterparties at a net cost of $96.8 million. The 2026 Capped Call Transactions are purchased capped call options on 33.9 million shares Class A common stock, that, if exercised, can be net share settled, net cash settled, or settled in a combination of cash or shares consistent with the settlement elections made with respect to the 2026 Notes if converted. The cap price is initially $32.57 per share of our Class A common stock and subject to certain adjustments under the terms of the 2026 Capped Call Transactions. The strike price is initially $19.70 per share of Class A common stock, subject to customary anti-dilution adjustments that mirror corresponding adjustments for the 2026 Notes. The 2026 Capped Call Transactions are intended to reduce potential dilution to holders of our Class A common stock upon conversion of the 2026 Notes and/or offset any cash payments we are required to make in excess of the principal amount, as the case may be, with such reduction or offset subject to a cap. The cost of the Capped Call Transactions was recorded as a reduction of our additional paid-in

Share-based Payment Arrangement [Abstract]
Stock Based Compensation	12. Stock Based Compensation Upon completion of the Business Combination, the 2016 Stock Plan renamed the 2020 Equity Incentive Plan (the “Plan”). All outstanding awards under the 2016 Stock Plan are modified to adopt the terms under the 2020 Equity Incentive Plan. The modifications are administrative in nature and have no effect on the valuation inputs, vesting conditions or equity classification of any of the outstanding original awards immediately before and after the close of the Business Combination. The Plan is a stock-based compensation plan which provides for the grants of options and restricted stock to employees and consultants of the Company. Options granted under the Plan may be either incentive options (“ISO”) or nonqualified stock options (“NSO”). The Plan added 24,097,751 shares of Class A Common Stock on October 29, 2020 to increase the maximum aggregate number of shares that may be issued under the Plan to 47,798,209 shares (subject to adjustments upon changes in capitalization, merger or certain other transactions). Also, upon completion of the Business Combination, the Company established a 2020 Employee Stock Purchase Plan (the “ESPP”) under which up to 3,213,034 Class A Common Stock may be issued. As of September 30, 2021, no shares have been issued under the ESPP. Stock-based compensation expense is as follows (in thousands): Three-months Ended September 30, 2021 2020 General and administrative expense $ 209 $ 140 Research and development 834 124 Total 1,043 264 Nine-months Ended September 30, 2021 2020 General and administrative expense $ 816 $ 178 Research and development 3,262 156 Total 4,078 334 Stock options Options under the Plan may be granted at prices as determined by the Board of Directors, provided, however, that (i) the exercise price of an ISO and NSO shall not be less than 100% of the estimated fair value of the shares on the date of grant, and (ii) the exercise price of an ISO granted to a 10% shareholder shall not be less than 110% of the estimated fair value of the shares on the date of grant. The fair value of the shares is determined by the Board of Directors on the date of grants. Stock options generally have a contractual life of 10 years. Upon exercise, the Company issues new shares. In 2016 and 2017, the Company’s founders were granted an aggregate of 15,882,711 options which are fully vested and are not related to performance. Options granted to other employees and consultants become vested and are exercisable over a range of up to six years from the date of grant. The following table summarizes option activity under the Plan: Options Weighted Average Exercise Price Weighted Average Contractual Term (in Years) Balance as of January 1, 2021 18,724,096 0.69 6.5 Granted 920,443 16.00 Exercised (977,952 ) 0.25 Forfeited (510,235 ) 7.21 Balance as of September 30, 2021 18,156,352 1.31 5.8 The fair value of each stock option grant under the Plan was estimated on the date of grant using the Black-Scholes option pricing model, with the following range of assumptions: Nine-months Ended September 30, 2021 Expected term (in years) 6.3 Volatility 94.9% to 97.5% Dividend yield 0.0% Risk-free interest rate 0.90% to 1.02% The Black-Scholes option pricing model requires various highly subjective assumptions that represent management’s best estimates of the fair value of the Company’s common stock, volatility, risk-free interest rates, expected term, and dividend yield. As the Company’s shares have actively traded for a short period of time subsequent to the Business Combination, volatility is based on a benchmark of comparable companies within the automotive and energy storage industries. The expected term represents the weighted-average period that options granted are expected to be outstanding giving consideration to vesting schedules. Since the Company does not have an extended history of actual exercises, the Company has estimated the expected term using a simplified method which calculates the expected term as the average of the time-to-vesting Restricted stock awards During the nine months ended September 30, 2021, the Company granted employees, who rendered services during the year ended December 31, 2020 and were employees of the Company on the grant date, a restricted stock unit (“RSU”) award based in proportion to the service period beginning from the employee’s hire date to the end of 2020. The restricted stock unit awards vested on the grant date which resulted in the release of 36,025 shares of Class A common stock, net of 20,232 shares withheld to pay for statutory withholding taxes, equal to stock-based compensation expense of $0.7 million recognized in the nine-months ended September 30, 2021. The Company’s founders declined to receive an award related to performance in 2020. In accordance with the Company’s Outside Director Compensation Policy, each outside Board of Directors member received an annual RSU equal to $200,000 granted on June 8, 2021 (the date of the Company’s annual shareholders’ meeting) or 15,723 shares of Class A common stock which vests in 25% increments at the end of each calendar quarter. Each Outside Director may elect to convert all or a portion of his or her annual Board of Directors retainer, excluding any annual retainer that an Outside Director may receive for serving as Lead Director and any annual retainers for committee service, into RSUs in lieu of the applicable cash retainer payment (“RSU Election”). The number of Class A common shares granted to Outside Directors annually are based on the 30-day Performance-based restricted stock awards In the third quarter of 2021, the Company’s compensation committee ratified and approved performance-based restricted stock units (“PRSUs”) to all employees (“Grantee”) the value of which is determined based on the Grantee’s level within the Company (“PRSU Value”). Each PRSU is equal to one underlying share of Class A common stock. Also, PRSUs will be awarded to any new employee hired in the fourth quarter of 2021 and during 2022 on a pro-rata 2,009,967

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company’s condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) as determined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”). Reverse Recapitalization The Business Combination was accounted for as a reverse recapitalization and Spartan was treated as the “acquired” company for accounting purposes. The Business Combination was accounted as the equivalent of Legacy Fisker issuing stock for the net assets of Spartan, accompanied by a recapitalization. Accordingly, all historical financial information presented in these consolidated financial statements represents the accounts of Legacy Fisker and its wholly owned subsidiaries “as if” Legacy Fisker is the predecessor to the Company. The shares and net loss per common share, prior to the Business Combination, have been adjusted as shares reflecting the exchange ratio established in the Business Combination. Going Concern, Liquidity and Capital Resources The Company evaluated whether there are any conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern over the next twelve months from the date of filing this report. Since inception, the Company has incurred significant accumulated losses of approximately $481 million. As of September 30, 2021, the Company had approximately $1,400 million in cash and cash equivalents. The Company expects to continue to incur significant operating losses for the foreseeable future. Proceeds from the Business Combination, issuance of convertible senior notes, and exercised public warrants and options provide the Company the liquidity and capital resources to fund its operating expenses and capital expenditure requirements for at least the next 12 months from issuance. Supplier Risk The Company continued nomination of suppliers with an accelerated phase during the quarter for engineering, development, testing, tooling and production of components for serial production of its vehicles. As of September 30, 2021, these supplier contracts do not represent unconditional purchase obligations with take-or-pay
Unaudited Interim Financial Statements	Unaudited Interim Financial Statements The condensed consolidated balance sheet as of September 30, 2021, the condensed consolidated statements of operations and the condensed consolidated statements of changes in temporary equity and stockholders’ equity (deficit) for the three-months and nine-months ended September 30, 2021 and 2020, and the condensed consolidated statements of cash flows for the nine-months ended September 30, 2021 and 2020, as well as other information disclosed in the accompanying notes, are unaudited. The consolidated balance sheet as of December 31, 2020 was derived from the audited consolidated financial statements as of that date. The interim condensed consolidated financial statements and the accompanying notes should be read in conjunction with the annual consolidated financial statements and the accompanying notes contained in our Annual Report on Form 10-K/A Comprehensive loss is not separately presented as the amounts are equal to net loss for the three-months and nine-months ended September 30, 2021 and 2020. The interim condensed consolidated financial statements and the accompanying notes have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The condensed consolidated financial statements for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future years or interim periods.
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP required management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the condensed consolidated financial statements and accompanying notes. The Company bases these estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates.
Fair Value Measurements	Fair Value Measurements The Company follows the accounting guidance in ASC 820, Fair Value Measurement The accounting guidance requires fair value measurements be classified and disclosed in one of the following three categories: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Observable inputs other than Level 1 prices, for similar assets or liabilities that are directly or indirectly observable in the marketplace. Level 3: Unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
Income Taxes	Income Taxes Income taxes are recorded in accordance with ASC 740, Income Taxes There are transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. As of September 30, 2021, there were no material changes to either the nature or the amounts of the uncertain tax positions previously determined for the year ended December 31, 2020. The Company’s income tax provision consists of an estimate for U.S. federal and state income taxes based on enacted rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in deferred tax assets and liabilities, and changes in the tax law. The Company maintains a valuation allowance against the full value of its U.S. and state net deferred tax assets because the Company believes the recoverability of the tax assets is not more likely than not as of September 30, 2021.
Debt issuance costs	Debt issuance costs Direct and incremental costs, including amounts paid to initial purchasers of the Company’s convertible notes, are directly attributed to efforts to obtain debt financing are debt issuance costs. Upon issuance of debt, the carrying value is the principal amount of debt reduced by any debt issuance costs. Debt issuance costs are attributed to interest expense and accreted over the expected term of the debt using the effective interest rate method.
Derivative Liability	Derivative Liability The Company accounts for its public and private warrants as a derivative liability initially measured at its fair values and remeasured in the condensed consolidated statements of operations at the end of each reporting period. When the warrants are exercised, the corresponding derivative liability is de-recognized
Equity Awards	Equity Awards The grant date for an option or stock award is established when the grantee has a mutual understanding of the key terms and conditions of the option or award, the award is authorized, including all the necessary approvals unless approval is essentially a formality or perfunctory, and the grantee begins to benefit from, or be adversely affected by, underlying changes in the price of the Company’s Class A common shares. An award or option is authorized on the date that all approval requirements are completed (e.g., action by the compensation committee approving the award and the number of options, restricted shares or other equity instruments to be issued to individual employees).
Leases	Leases Current portion of the Company’s lease liability is based on lease payments due within twelve months of the balance sheet date. Variable lease payments are included in lease payments when the contingency upon which the payment is dependent is resolved.
Net Loss per Share of Common Stock	Net Loss per Share of Common Stock Basic net loss per share of common stock is calculated using the two-class
