Polymarket becomes official prediction market partner of New York Yankees
Polymarket signed as the official prediction market partner of the New York Yankees on August 6. The deal runs through the remainder of the 2026 MLB season. Polymarket branding will appear on Yankee Stadium signage during games, including LED displays. This is Polymarket's first partnership with an individual MLB franchise, following its broader league-level deal with MLB. No financial terms were disclosed. The news was announced via a video posted August 7.
Polymarket gains a live marketing channel in America's largest media market, but the parallel Novig-Mets deal means neither platform owns New York exclusively. For Polymarket, the test is whether stadium branding converts sports bettors into event-contract traders faster than digital ads. Kalshi and Novig now face a build-or-buy decision on comparable sports partnerships or risk ceding this distribution layer.
The back-to-back MLB deals suggest team sponsorships are becoming a baseline cost of competing. Smaller platforms without Polymarket's deal flow will find the price of entry rising with every new signing. The next NFL or NBA team agreement will set the floor for every subsequent negotiation.
