MLB Names Polymarket Exclusive Prediction Market Exchange Partner and Signs Agreement with CFTC to Establish Integrity Framework

Major League Baseball (MLB) has named Polymarket as its Official Prediction Market Exchange and signed a memorandum of understanding (MOU) with the Commodity Futures Trading Commission (CFTC) regarding prediction market integrity.

Under the Polymarket partnership, Polymarket and its brokers will receive access to MLB marks and logos for use in their prediction market products, access to official league data from Sportradar (MLB's exclusive global data distributor for prediction markets), and brand exposure across MLB's digital channels and at league events. As part of the agreement, MLB and Polymarket will work together to restrict markets that present integrity risks, including those based on individual pitches, manager decisions and umpire performance. Polymarket will also integrate integrity controls into its US Rulebook, applying them to all of its brokers.

The MOU with the CFTC establishes an information-sharing arrangement between MLB and the commission regarding the integrity of professional baseball and related prediction markets. Shared information will be treated confidentially, and designated representatives from each organization will meet regularly. MLB signed the MOU one year after writing to the CFTC calling for integrity protections in the prediction market space.

While Polymarket holds exclusive Official Partnership rights, MLB says it intends to establish integrity relationships with all other prediction market exchanges offering baseball contracts, requiring them to integrate integrity protections into their individual rulebooks.

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 Robert D. Manfred, Jr. Protecting the integrity of the game on the field is our top priority. By engaging in this community, we are able to work together to create clear boundaries with the goal of mitigating risk while providing fan engagement opportunities.

Polymarket is about bringing fans closer to the moments that define sports, said Shayne Coplan, Founder and CEO of Polymarket. By working collaboratively with Major League Baseball and regulators, we can create new ways for fans to engage with the game while protecting the integrity of the sport.
