Overview
- Polymarket receives exclusive rights to use MLB marks and logos and access to official league data from Sportradar to help resolve markets, along with leaguewide branding opportunities.
- The memorandum of understanding with the CFTC—its first with a pro sports body—establishes confidential information-sharing and regular meetings to address fraud, manipulation and other abuses.
- MLB and Polymarket will restrict markets seen as vulnerable to manipulation, including wagers on individual pitches, manager decisions and umpire performance.
- The deal includes a clause allowing the partnership to be voided if courts find prediction markets violate state law, and it follows Arizona’s criminal charges against rival platform Kalshi.
- MLB says it will pursue integrity relationships with other exchanges and require them to adopt baseball’s protections as the CFTC asserts federal oversight in disputes with state regulators.
