Kalshi adds Paul-Alcaraz and Khachanov-Bonzi to US Open men's singles markets
Kalshi listed prediction markets for the Paul vs Alcaraz round of 16 and Khachanov vs Bonzi round of 32 men's singles matches at the US Open. The listings let users track implied odds or trade match outcomes. Separately, Kalshi traders are pricing Coco Gauff a 74% favorite over Iva Jovic in their round of 16 matchup, with Aryna Sabalenka as the title favorite on the platform. Kalshi is the official prediction market partner of the US Open under an exclusive, multi-year deal signed earlier this month.
These match listings are thin-book products without proven depth. Kalshi traders see Gauff at 74% and Sabalenka as title favorite, but the platform has yet to show it can absorb sharp size without violent repricing — the Alcaraz swing to 34% after Sinner's injury exit demonstrated how quickly these prices gap.
Novig's $125 million debut week and Polymarket's established liquidity pools pull two-sided flow toward tighter spreads elsewhere. Kalshi's exclusive US Open partnership buys broadcast visibility and official partner status, not inventory lockup, since Robinhood Derivatives lists the same tournament matches. Traders must weigh court-side brand against potentially better fills elsewhere, with no guarantee Kalshi spreads hold under pressure.
