Major League Baseball (MLB) has officially entered the prediction markets space by naming Polymarket as its Official Prediction Market Exchange, marking a significant step in how sports leagues engage with emerging wagering formats.
Strategic Collaboration with Regulatory Oversight
As part of the agreement, MLB Commissioner Robert D. Manfred signed a memorandum of understanding with Commodity Futures Trading Commission (CFTC) Chairman Michael S. Selig. The MOU establishes a framework for information sharing between the league and the regulator, with all shared data treated confidentially.
This collaboration signals a more structured and compliant approach to prediction markets, particularly as regulators and sports bodies seek to better understand and oversee this fast-growing segment.
Data Access and Brand Integration
Under the partnership, Polymarket gains exclusive access to MLB’s official marks and logos, alongside official league data provided by Sportradar.
In addition, the platform will benefit from brand exposure across MLB’s digital channels and at league events, significantly increasing its visibility among baseball fans. This level of integration highlights MLB’s intent to position prediction markets as part of the broader fan engagement ecosystem.
Integrity Measures at the Core
A key component of the agreement is the implementation of a robust integrity framework. Both parties will collaborate to identify and restrict markets that could pose risks to the sport’s integrity.
Polymarket will also incorporate these safeguards into its U.S. Rulebook, ensuring that its offerings align with league standards and regulatory expectations. Notably, MLB had already urged the CFTC a year earlier to introduce stronger integrity protections in the prediction market space, making this partnership a natural progression of those efforts.
Expanding Fan Engagement—With Safeguards
According to Commissioner Robert D. Manfred, the agreement represents a proactive step in managing the rise of prediction markets while maintaining the integrity of the game.
At the same time, Shayne Coplan emphasized that the partnership aims to bring fans closer to key moments in sports through innovative engagement tools, while ensuring appropriate safeguards remain in place.
A Defining Moment for Sports and Prediction Markets
This partnership underscores a broader industry trend: traditional sports leagues are beginning to formally engage with prediction market platforms rather than operate at a distance. By working alongside regulators like the Commodity Futures Trading Commission, MLB is helping shape how this new category evolves within a compliant and controlled framework.
Ultimately, the deal positions Polymarket at the center of a rapidly developing space—one where fan engagement, data, and regulation increasingly intersect.
