Yankees designate Polymarket as team's prediction-markets partner

Polymarket has added a Major League Baseball club to its sponsorship portfolio, announcing on Aug. 6 that it will serve as the New York Yankees' designated prediction-market provider. The franchise-level pact is the platform's first with an individual MLB team, following the exclusive agreement it signed with MLB earlier in the season.

Stadium activation and fan experiences

Branding for Polymarket will appear at Yankee Stadium through the remainder of the 2026 campaign, including LED displays and home-plate signage shown during locally televised games on YES Network and Prime Video. The arrangement also grants the platform access to in-stadium hospitality assets and fan-facing opportunities, such as Kids Run the Bases and slots for delivering the lineup card.

Broader sports push

The Yankees deal extends a series of sports partnerships Polymarket has assembled this year. In March, MLB named the firm its official prediction-market exchange partner and separately signed a memorandum of understanding with the Commodity Futures Trading Commission covering integrity matters tied to prediction markets. Two months later, Polymarket became the official and exclusive prediction-market partner of Liga MX in the U.S., with Genius Sports supplying official data for contract settlement and integrity monitoring.

Regulatory context

The expansion arrives amid ongoing uncertainty over how sports prediction contracts should be treated in the U.S. Polymarket's domestic operations run through QCX LLC, which holds a CFTC designation as a contract market, with Polymarket Clearing serving as its derivatives clearing organization. In June, the CFTC proposed a framework for event contracts involving gaming and sports that would introduce a 90-day review process and public-interest criteria for individual offerings.

State regulators have pushed back in some cases. New York Attorney General Letitia James has contended that sports event contracts from prediction markets can fall within state gambling statutes, and joined a multistate filing supporting Massachusetts in its enforcement action against Kalshi. New York officials have also cautioned that promoting unlicensed sports wagering could violate state law.

Overseas, scrutiny continues to mount. In July, Polymarket restricted access for users in Ireland, adding the country to a growing list of jurisdictions where the platform has limited its availability.
