Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation These unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim reporting. As such, certain notes or other information that are normally required by U.S. GAAP have been omitted if they substantially duplicate the disclosures contained in the Company’s annual audited consolidated financial statements. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and related notes as of and for the fiscal year ended December 31, 2022, which are included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as filed with the SEC on February 17, 2023 (the “2022 Annual Report”). These condensed consolidated financial statements are unaudited; however, in the opinion of management, they include all normal and recurring adjustments necessary for a fair presentation of the Company’s condensed consolidated financial statements for the periods presented. Results of operations reported for interim periods are not necessarily indicative of results for the entire year, due to seasonal fluctuations in the Company’s revenue as a result of timing of various sports seasons, sporting events and other factors. The Company consummated the GNOG Transaction on the GNOG Closing Date. In the GNOG Transaction, the Company was determined to be the accounting acquirer and, as such, the acquisition is considered a business combination under Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (“ASC 805”), and was accounted for using the acquisition method of accounting. These unaudited condensed consolidated financial statements include the accounts and operations of the Company, except that, due to the timing of the consummation of the GNOG Transaction, these unaudited condensed consolidated financial statements exclude the operations of GNOG prior to the GNOG Closing Date. All intercompany accounts and transactions are eliminated upon consolidation. Certain amounts, which are not material, in the prior year’s consolidated financial statements have been reclassified to conform to the current year presentation.
Segments	Segments The Company regularly reviews its operating segments and the approach used by the chief operating decision maker (“CODM”) to evaluate performance and allocate resources. As a result of the Company’s acquisition of DK Crown Holdings Inc. (formerly DraftKings Inc.), a Delaware corporation (“DK DE”), and SBTech (Global) Limited (“SBTech”) and the consummation of the transactions contemplated by the business combination agreement, dated December 22, 2019 (as amended), in April 2020, the Company began to identify two distinct operating segments: a business-to-consumer (“B2C”) segment, which included its Sportsbook, iGaming and DFS product offerings, as well as media and other consumer product offerings, and a business-to-business (“B2B”) segment, which had principal activities involving the design and development of gaming software. However, beginning in the fourth quarter of 2022, as a result of the Company’s integration of the technology and expertise of SBTech, the Company began to view the B2B segment primarily as a cost center of the B2C segment and, therefore, began to operate its business and report its results as a single operating segment. The Company’s determination that it operates as a single segment is consistent with the financial information regularly reviewed by the CODM for purposes of evaluating performance, allocating resources and planning and forecasting for future periods. The Company’s CODM allocates resources and assesses financial performance on a consolidated basis. Prior periods have been reclassified to conform with the new segment presentation.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”), which clarifies the guidance in Accounting Standards Codification Topic 820, Fair Value Measurement (“Topic 820”), when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security and introduces new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. ASU 2022-03 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, and early adoption is permitted. While the Company is continuing to assess the timing of adoption and the potential impacts of ASU 2022-03, it does not expect ASU 2022-03 to have a material effect on the Company’s consolidated financial condition, results of operations or cash flows.
