Overview
- Polymarket is granted exclusive rights to use MLB marks and logos, access official data through Sportradar, and receive promotion across league platforms under the multi-year pact.
- A shared integrity framework will bar or limit high-risk contracts, including markets on individual pitches and on manager or umpire decisions, with uniform controls embedded in Polymarket’s U.S. rulebook.
- A first-of-its-kind memorandum with the CFTC establishes confidential information-sharing and regular meetings to monitor baseball-related event contracts and respond to potential threats.
- MLB says it will seek integrity agreements with other exchanges offering baseball markets, while state actions such as Arizona’s criminal case against Kalshi leave the regulatory landscape unsettled.
- Front Office Sports reports the deal’s value between roughly $150 million and $300 million over multiple years, and ESPN reports the agreement can be voided if courts find prediction markets violate state law.
