Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Tradeweb Markets Inc. (the “Corporation”) was incorporated as a Delaware corporation on November 7, 2018 to carry on the business of Tradeweb Markets LLC (“TWM LLC”) following the completion of a series of reorganization transactions on April 4, 2019 (the “Reorganization Transactions”), in connection with Tradeweb Markets Inc.’s initial public offering (the “IPO”), which closed on April 8, 2019. Following the Reorganization Transactions, Refinitiv (as defined below) owned an indirect majority ownership interest in the Company (as defined below). On January 29, 2021, London Stock Exchange Group plc (“LSEG”) completed its acquisition of the Refinitiv business from a consortium, including certain investment funds affiliated with The Blackstone Group Inc. (f/k/a The Blackstone Group L.P.) (“Blackstone”) as well as Thomson Reuters Corporation (“TR”), in an all share transaction (the “LSEG Transaction”). In connection with the LSEG Transaction, the Corporation became a consolidating subsidiary of LSEG. Prior to the LSEG Transaction, the Corporation was a consolidating subsidiary of BCP York Holdings (“BCP”), a company owned by certain investment funds affiliated with Blackstone, through BCP’s previous majority ownership interest in Refinitiv. As used herein, “Refinitiv,” prior to the LSEG Transaction, means Refinitiv Holdings Limited, and unless otherwise stated or the context otherwise requires, all of its direct and indirect subsidiaries, and subsequent to the LSEG Transaction, refers to Refinitiv Parent Limited, and unless otherwise stated or the context otherwise requires, all of its subsidiaries. Refinitiv owns substantially all of the former financial and risk business of Thomson Reuters (as defined below), including, prior to and following the completion of the Reorganization Transactions, an indirect majority ownership interest in the Company. The Refinitiv business was rebranded by LSEG as LSEG Data & Analytics during the fourth quarter of 2023. The Corporation is a holding company whose principal asset is LLC Interests (as defined below) of TWM LLC. As the sole manager of TWM LLC, the Corporation operates and controls all of the business and affairs of TWM LLC and, through TWM LLC and its subsidiaries, conducts the Corporation’s business. As a result of this control, and because the Corporation has a substantial financial interest in TWM LLC, the Corporation consolidates the financial results of TWM LLC and reports a non-controlling interest in the Corporation’s condensed consolidated financial statements. As of both March 31, 2025 and December 31, 2024, Tradeweb Markets Inc. owned 90.2% of TWM LLC and the non-controlling interest holders owned the remaining 9.8% of TWM LLC. References to LLC Interests held by Tradeweb Markets Inc. and comparable terminology refer to LLC Interests held by Tradeweb Markets Inc. directly as well as indirectly through direct, wholly-owned subsidiaries of Tradeweb Markets Inc. (which are holding companies with no independent operations). Unless the context otherwise requires, references to the “Company” refer to Tradeweb Markets Inc. and its consolidated subsidiaries, including TWM LLC, following the completion of the Reorganization Transactions, and TWM LLC and its consolidated subsidiaries prior to the completion of the Reorganization Transactions. A majority interest of Refinitiv (formerly the Thomson Reuters Financial & Risk Business) was acquired by BCP on October 1, 2018 (the “Refinitiv Transaction”) from TR. The Refinitiv Transaction resulted in a new basis of accounting for certain of the Company’s assets and liabilities beginning on October 1, 2018. See Note 2 – Significant Accounting Policies for a description of pushdown accounting applied as a result of the Refinitiv Transaction. In connection with the Reorganization Transactions, TWM LLC’s limited liability company agreement (the “TWM LLC Agreement”) was amended and restated to, among other things, (i) provide for a new single class of common membership interests in TWM LLC (the “LLC Interests”), (ii) exchange all of the then existing membership interests in TWM LLC for LLC Interests and (iii) appoint the Corporation as the sole manager of TWM LLC. LLC Interests, other than those held by the Corporation, are redeemable or exchangeable in accordance with the TWM LLC Agreement for shares of Class A common stock, par value $0.00001 per share, of the Corporation (the “Class A common stock”) or Class B common stock, par value $0.00001 per share, of the Corporation (the “Class B common stock”), as the case may be, on a one-for-one basis. As used herein, references to “Continuing LLC Owners” refer collectively to (i) those owners of TWM LLC prior to the Reorganization Transactions (the “Original LLC Owners”), including an indirect subsidiary of Refinitiv, certain investment and commercial banks (collectively, the “Bank Stockholders”), and members of management, that continued to own LLC Interests after the completion of the IPO and Reorganization Transactions and that received shares of Class C common stock, par value $0.00001 per share, of the Corporation (the “Class C common stock”), shares of Class D common stock, par value $0.00001 per share, of the Corporation (the “Class D common stock”) or a combination of both, as the case may be, in connection with the completion of the Reorganization Transactions, (ii) any subsequent transferee of any Original LLC Owner that has executed a joinder agreement to the TWM LLC Agreement and (iii) solely with respect to the Tax Receivable Agreement (as defined in Note 7 – Tax Receivable Agreement), (x) those Original LLC Owners, including certain of the Bank Stockholders, that disposed of all of their LLC Interests for cash in connection with the IPO and (y) any party that has executed a joinder agreement to the Tax Receivable Agreement in accordance with the Tax Receivable Agreement.
