Three tennis tournaments in talks with prediction market platforms
Officials at the Cincinnati Open, BNP Paribas Open, and DC Open say prediction-market platforms have approached them about partnerships or integrations. The talks involve three of the largest hard-court tennis tournaments in the United States. No platforms are named and no deals have been announced. The outreach follows Kalshi's exclusive deal with the US Open, which the platform announced recently. Tennis ranks among the top three most-bet sports globally and remains highly exposed to match-fixing risk.
Tennis is an attractive but risky expansion target for prediction markets. The sport ranks among the top three most-bet globally, yet it carries outsized match-fixing exposure that could trigger regulatory backlash against any platform that closes a deal. Kalshi's US Open exclusivity gave it Grand Slam inventory rivals cannot match, but that advantage only holds if competitors stay locked out of other major tournaments.
Cincinnati, Indian Wells, and the DC Open represent the next tier of hard-court events in the United States. Kalshi or Polymarket lands even one of them, they extend their lead in spectrum. If a rival like Robinhood Derivatives or Novig breaks through instead, Kalshi's Open-era moat starts to look like a single-tournament badge. The fix-risk means any deal will face sharper compliance scrutiny than typical sports partnerships.
