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”). Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. The Company believes the disclosures made are adequate to make the information presented not misleading. The condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and one subsidiary for which there is an immaterial noncontrolling interest at June 30, 2025. All significant intercompany balances and transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements reflect all adjustments of a normal and recurring nature that are, in the opinion of the Company’s management, necessary for the fair presentation of the results of operations for the interim periods. Operating results for the six months ended June 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified or changed to conform to the current-year presentation. Such reclassifications had no impact on previously reported net income.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates, judgments, and assumptions that affect the amounts reported in these condensed consolidated financial statements and the accompanying notes. Estimates are used in several areas including, but not limited to, end-user incentives, including Bonus Cash and Ticketz accrual, indirect tax liabilities, the fair value of non-marketable securities, and the impairment of long-lived assets. 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. The actual results may materially differ from these estimates.
Revenue Recognition	Revenue Recognition The Company recognizes revenue for its services in accordance with the FASB ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). For additional information, see Note 3, Revenue. Revenues from Entry Fees The Company generates substantially all its revenues through its competition-based Skillz segment by providing a service to game developers for monetization of their game content. The monetization service provided by Skillz allows developers to offer multi-player competition to their end-users for the purpose of end-user retention and engagement. Skillz provides developers with a software development kit (“SDK”) they can download and integrate with their existing games. The SDK serves as a data interface between Skillz and the game developers that enables Skillz to provide monetization services to the developer. Games provided by three developer partners accounted for 69% and 70% of the Company’s consolidated revenue for three and six months ended June 30, 2025, respectively. Games provided by three developer partners accounted for 81% and 80% of the Company’s consolidated revenue for the three and six months ended 2024, respectively. End-User Incentive Programs To drive traffic to the platform, the Company provides promotions and incentives to end-users in various forms. Evaluating whether a promotion or incentive is a payment to a customer may require significant judgment. Promotions and incentives, which are consideration payable to customers, are recognized as a reduction of revenue at the later of when revenue is recognized or when the Company pays or promises to pay the incentive. Promotions and incentives recorded as sales and marketing expenses are recognized when we incur the related cost. For the three and six months ended June 30, 2025, the Company recognized a reduction of revenue of $2.0 million and $4.8 million, respectively, related to these end-user incentives. For the three and six months ended June 30, 2024, the Company recognized a reduction of revenue of $2.7 million and $6.1 million, respectively, related to these end-user incentives. For the three and six months ended June 30, 2025, the Company recognized sales and marketing expense of $8.1 million and $17.6 million, respectively, related to these end-user incentives. For the three and six months ended June 30, 2024, the Company recognized sales and marketing expense of $10.6 million and $19.3 million, respectively, related to these end-user incentives. From time to time, the Company issues credits or refunds to end-users that are dissatisfied by the level of service provided by the game developer. There is no contractual obligation for the Company to refund such end-users nor is there a valid expectation by game developers for the Company to issue such credits or refunds to end-users on their behalf. The Company accounts for credits or refunds, which are not recoverable from the game developer, as sales and marketing expenses when incurred. Advertising Revenue The Company offers a technology platform (i.e. demand side platform, “DSP”) to source available advertising space from its network of vendors / suppliers (aka, advertising exchange partners / publishers), which uses a real-time auction process. The revenue from advertising is recognized over time based on the number of impressions as the performance obligation is satisfied. The Company considers itself the agent of its customer(s). This is due to the Company’s involvement in programmatically placing and sourcing advertisements on behalf of customers via a network of third party publishers. The Company does not, at any time, take ownership of advertising inventory being sourced and placed. Via the DSP, if the Company wins the auction and an impression is served, the customer’s advertisement is displayed on the publisher / supplier’s mobile application. For performance obligations related to advertising revenue, customers are extended 30 day payment terms from completion of each month’s insertion order and no advertising revenue customers accounted for more than 5% of the Company’s revenue in either of three and six months ended June 30, 2025 and 2024, respectively. The Company recognizes an asset for incremental costs of obtaining a contract with the customer as long as Management expects to recover these costs. Incremental costs are those that would have not been incurred if the contract did not exist. Examples of incremental costs often capitalized are sales commissions whereas examples of costs that would not be included are internal employee salaries, standard benefits, travel costs, and other / general legal costs. Sales commissions are the only incremental contract costs the Company incurs and are paid based on collected revenue based on the recipient’s assigned accounts. As commissions are typically satisfied within one year after an executed contract, the Company applies the practical expedient under ASC 340-40, Other Assets and Deferred Costs: Contracts with Customers. Maintenance Fee Revenue When a player becomes inactive on the platform by not participating in a tournament for six consecutive months, the Company will impose a monthly maintenance fee. This fee is charged to the player and recognized as revenue by the Company beginning in the seventh month of inactivity.
Cost of Revenue	Cost of Revenue Cost of revenue primarily consists of third-party payment processing fees, server costs, amortization of developed technology, personnel expenses, direct software costs, amortization of internal use software, hosting expenses, and allocation of shared facility and other costs.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents consist of cash, commercial paper, money market funds and U.S. government agency securities with maturities of three months or less when purchased.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist of cash, cash equivalents, restricted cash, and marketable securities. Although the Company deposits its cash with multiple established financial institutions, the deposits, at times, may exceed federally insured limits. The Company has not experienced losses on its deposits of cash and cash equivalents. The Company limits the amount of credit exposure to any one issuer and monitors the financial condition of the financial institutions on a regular basis. At June 30, 2025, the Company had cash balances on deposit with various financial institutions that in the aggregate exceeded the federally insured limits in the amount of $235.4 million.
Accounts Receivable, Net	Accounts Receivable, Net Accounts receivable, net, represents amounts recorded for programmatic media campaigns, net of an allowance for credit losses from our advertising revenue customers of our Aarki segment. The allowance for credit losses is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense in the condensed consolidated statements of operations and comprehensive (loss) income. The Company assesses collectability by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when there are specific customers with known disputes or collectability issues. In determining the amount of the allowance for credit losses, the Company considers historical collectability based on past due status and makes judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data.
Long-Lived Assets	Long-Lived Assets Long-lived assets primarily consist of property and equipment with estimable useful lives subject to depreciation and amortization. The Company owns its office building in Las Vegas, Nevada that serves as its headquarters with costs allocated to building and land components. The building is depreciated on a straight-line basis over its estimated useful life of 39 years and the land is not subject to depreciation.
Advertising and Promotional Expense	Advertising and Promotional Expense Advertising and promotional expenses are included in sales and marketing expenses within the condensed consolidated statements of operations and comprehensive (loss) income and are expensed when incurred.
User Acquisition	User Acquisition User acquisition (“UA”) marketing costs to acquire new paying users to the platform are presented in sales and marketing expenses in the consolidated statements of operations and comprehensive loss.
Indirect Tax Liabilities	Indirect Tax Liabilities The Company is subject to indirect taxes such as sales and use tax in the United States and value-added tax in certain foreign jurisdictions, respectively. Indirect tax liabilities are adjusted considering changing facts and circumstances, such as the closing of a tax examination, further interpretation of existing tax law, or new tax law. The Company recognizes changes to its estimate if it is estimable and probable that its position would not be sustainable upon examination by taxing authorities. Although management believes the Company’s recorded liabilities are reasonable, no assurance can be given that the final tax outcomes of these matters will not be different from that which its liabilities are based on. To the extent that final tax outcomes of these matters are different than the amounts recorded, such differences could have a material impact on the Company’s condensed consolidated financial statements as the Company records related tax reserves as a reduction in revenue, and penalties and interest in general and administrative expenses.
401(k) Plan	401(k) Plan The Company has a 401(k) Plan that qualifies as a deferred salary arrangement under Section 401 of the Internal Revenue Code. Under the 401(k) Plan, participating employees may defer a portion of their pretax earnings and receive a matching employer contribution of up to 3% of compensation not to exceed the maximum amount allowable.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires enhanced annual disclosures regarding the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for annual periods beginning after December 15, 2024 and may be adopted on a prospective or retrospective basis. Early adoption is permitted. The Company is evaluating the impact of this guidance on its consolidated financial statements and related disclosures. In November 2024, the Financial Accounting Standards Board (FASB) issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” and issued an amendment ASU 2025-01 in January 2025 that clarified the effective date. The new standard requires public entities to disclose disaggregated information about certain costs and expenses in the notes to their financial statements in both annual and interim filings. ASU 2024-03 is effective for financial statements issued for annual reporting periods beginning after December 15, 2026, with early adoption permitted and can be applied either prospectively or retrospectively. The Company is evaluating the disclosure requirements related to the new standard.
