MLB Bets on Prediction Markets with $300M Polymarket Deal
Major League Baseball has launched its first official partnership in the prediction market space, signing a multi-year exclusive deal with Polymarket. The agreement, reported to be worth between $150 million and $300 million over three years, grants Polymarket the exclusive rights to use MLB logos and branding. The platform will also gain access to official league data through Sportradar, MLB's exclusive data distributor, to settle trades on events like game outcomes and player performance.
This move follows similar partnerships by other major sports leagues, including the NHL, MLS, and UFC, indicating a broader strategy to engage with this new form of fan participation. MLB Commissioner Rob Manfred stated the partnership is an "imperative step" in proactively managing the rapidly growing prediction market space, framing it as an opportunity for both fan engagement and risk mitigation. However, the deal includes a clause that allows it to be voided if courts rule that prediction markets are illegal under state law, acknowledging the sector's uncertain legal standing.
MLB and CFTC Sign First-Ever Integrity Pact
To address concerns about market manipulation, MLB concurrently signed a memorandum of understanding (MOU) with the U.S. Commodity Futures Trading Commission (CFTC). This marks the first such agreement between a professional sports league and the federal agency, establishing a formal channel for sharing information to protect the integrity of baseball and related markets. Both parties will now work to identify suspicious trading activity and restrict markets that pose a high risk, such as those on individual pitches or umpire performance.
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.

CFTC Chair Michael S. Selig praised the collaboration, noting it positions the agency to "protect these markets and its participants from fraud, manipulation, and other abuses." The pact aims to create clear boundaries and provide a framework for swift responses to integrity incidents, a critical concern following recent betting scandals in professional sports.
Gaming Industry Pushes Back on Federal "Workaround"
Despite the league's integrity-focused framing, the partnership has drawn sharp criticism from the traditional gaming industry. The American Gaming Association (AGA) questioned the legitimacy of the deal, arguing that prediction markets operate as unlicensed sports betting outside of state-regulated frameworks.
A multi-hundred million-dollar partnership or a memorandum of understanding with the CFTC doesn’t make an unlawful business model legitimate.

The core of the conflict lies in jurisdiction. Prediction markets assert they are financial derivative platforms under the CFTC's federal oversight, while the AGA and several states contend they are a form of gambling that must comply with state-by-state sports betting laws. This legal battle is actively playing out, with Polymarket and its rivals facing lawsuits in states like Michigan and Arizona, casting a shadow over the long-term viability of these sports partnerships.
