MLB Signs Exclusive Polymarket Deal, 'Integrity Framework' Agreement With CFTC

Major League Baseball announced Thursday that it has named Polymarket as its exclusive official partner for prediction markets, following the lead of leagues like the National Hockey League and Major League Soccer that have also signed deals with prediction market platforms. On top of that, MLB Commissioner Robert Manfred signed a memorandum of understanding (MOU) with the Commodity Futures Trading Commission (CFTC), a move that builds on MLB's 2024 letter to the agency calling for stronger integrity protections in the prediction market industry. The Polymarket partnership grants the platform and its brokers exclusive access to MLB branding and logos, official league data through Sportradar, and exposure across MLB's digital channels and events.

Front Office Sports was first to report on the multi-year deal, just ahead of the official announcement. Central to the deal is a shared integrity framework, under which both parties will work to restrict markets that could pose integrity risks—such as those involving individual pitches, managerial decisions, or umpire performance. Polymarket will also embed integrity controls into its U.

S. rulebook, holding all its brokers to uniform standards. <span data-mce-type="bookmark" style="display: inline-block; width: 0px; overflow: hidden; line-height: 0;" class="mce_SELRES_start"></span> The MOU with the CFTC establishes a formal channel for confidential information-sharing between the two organizations, regarding the integrity of professional baseball and its related prediction markets.

Designated representatives will meet regularly to monitor and address potential threats. “The new agreements that we formed with Polymarket and the CFTC are imperative steps in proactively managing the new and rapidly growing prediction market space,” said Commissioner Manfred, in a statement. “Protecting the integrity of the game on the field is our top priority.
