The multi-year deal gives Polymarket exclusive rights to use MLB and team logos, marks and official data for settling markets on games, player props and futures. Fans will soon see deeper integration across MLB digital platforms, with yes/no shares traded like stocks on everything from World Series odds to in-season storylines.
The partnership includes strict integrity rules that bar high-risk contracts, such as individual pitches or managerial decisions, to guard against manipulation. MLB will receive significant revenue — industry estimates place the value between $150 million and $300 million over three years — while gaining better visibility into trading activity that could flag suspicious patterns.
The move follows similar pacts by the NHL, MLS and UFC, signaling prediction markets’ rapid shift from crypto niche to mainstream sports engagement tool. At the same time, Commissioner Rob Manfred and CFTC Chairman Michael Selig signed a memorandum of understanding in Miami that establishes confidential information sharing and regular consultations on potential threats.
The framework mirrors MLB’s existing sports-betting integrity deals but applies to CFTC-regulated event contracts, giving the league and federal regulators a unified front amid ongoing debates with state gambling authorities. Supporters hail the arrangement as smart business that boosts fan interaction and protects the game; critics worry it blurs lines between entertainment and wagering. With billions expected to trade on baseball this season, the partnership could reshape how leagues monitor and monetize collective sentiment around America’s pastime.
