Item 1.01 Entry ~~Into~~into Aa Material Definitive Agreement.

On December 31, 2025, Tradeweb Markets LLC (“Tradeweb Markets”), a wholly owned subsidiary of Tradeweb Markets Inc. (the “Company”), ~~and~~entered into a series of amendments effective as of November 1, 2025 (the “Amendments”) with Refinitiv US LLC and Refinitiv US Organization LLC (together, the “LSEG Parties”) ~~reached an agreement-in-principle~~ to ~~renew~~ the ~~current data schedules under the~~ master data license agreement, effective as of November 1, 2023, ~~between~~among Tradeweb Markets and the LSEG Parties (the “Master Data Agreement”) ~~for an additional three-year term (the “Renewal”)~~. The contemplated Renewal is expected to apply retrospectively to November 1, 2025 and to reflect the broader and deeper quality of data now being provided by Tradeweb Markets under the Master Data Agreement. The contemplated Renewal remains subject to execution of definitive documentation, as well as other factors, including Board approval. Therefore, as contemplated in the current data schedules, on October 29, 2025, Tradeweb Markets delivered notice to the LSEG Parties to commence a 12-month transition period while the Renewal is finalized.

As part of the Amendments, on December 31, 2025, Tradeweb Markets and Refinitiv US LLC entered into amended and restated Data Schedules 1, 2, 4 and 5 to the Master Data Agreement, each effective as of November 1, 2025 (the “Restated Data Schedules”). Data Schedule 3 to the Master Data Agreement had automatically terminated by its own terms effective as of October 31, 2024. Pursuant to the Restated Data Schedules, Tradeweb Markets will continue to license certain market data (including real time feeds) for multiple fixed income and derivatives products to Refinitiv US LLC and its relevant affiliates (collectively, the “LSEG Subscriber”) in exchange for fixed license fees or, in some cases, fees payable based on a percentage of revenue generated by the LSEG Subscriber.

The initial license or service period under each of the Restated Data Schedules runs from November 1, 2025 through October 31, 2028 and automatically renews for up to two additional successive two-year periods unless notice of non-renewal is provided by either party at least 180 days prior to the expiration of such initial license or service period (or the expiration of the first automatic extension period, if applicable). Following the initial license or service period or any automatic extension period, if applicable, each Restated Data Schedule also includes the option, upon notice of either party to the other party, for a twelve-month transition period following such period to allow for an orderly transition of the market data distribution arrangements contemplated under such Restated Data Schedule.

Except as set forth in the Amendments, all of the terms and conditions set forth in the Master Data Agreement shall remain in full force and effect.

The LSEG Parties are affiliates of the London Stock Exchange Group plc (“LSEG”), which is the indirect controlling stockholder of the Company. Affiliates of LSEG have various relationships with the Company. For further information, see the Company’s Definitive Proxy Statement on Schedule 14A, filed on March 27, 2025.
