Kalshi Lands Exclusive US Open Prediction Market Deal
Rival platforms barred from advertising at the tournament and on ESPN broadcasts.
Kalshi has secured an exclusive prediction market partnership with the US Open tennis tournament, locking rival platforms out of advertising at the event and on its ESPN broadcasts, according to The Block.
Why It Matters
Exclusive sports partnerships are a proven playbook in traditional sports betting — DraftKings and FanDuel spent years fighting for official NFL and NBA data deals — and Kalshi is now importing that strategy into regulated prediction markets. The ESPN broadcast exclusivity is particularly significant: it bars competitors such as Polymarket and any emerging CFTC-regulated rivals from reaching what is one of tennis's largest American TV audiences. For bettors and traders, this signals that prediction markets are graduating from niche crypto-adjacent products into mainstream sports sponsorship territory. Kalshi's ability to land this deal as of August 2026 reflects the market's rapid legitimization following years of regulatory back-and-forth with the CFTC.
Context
Kalshi operates as a CFTC-regulated event contract market, allowing US users to trade on real-world outcomes including sports results. The US Open, held annually in New York, draws tens of millions of viewers across its ESPN and ESPN2 broadcasts, making it a high-visibility platform for any financial or wagering product. Prediction markets as a category gained substantial mainstream attention through the 2024 US election cycle, when platforms recorded hundreds of millions in trading volume on political outcomes.
What's Next
Watch for Kalshi to activate on-site branding at the USTA Billie Jean King National Tennis Center in Flushing, New York as the tournament runs through this week. A successful US Open activation would likely accelerate pitches to other major sports rights holders across the NFL, NBA, and golf.
