Description

This market focuses on determining which player will win the second set of a professional tennis match between Marta Kostyuk and Sloane Stephens. The outcome depends solely on the performance of the athletes during the specified set, with specific conditions addressing potential match disruptions such as injuries, cancellations, or retirements.

Kalshi

The market resolves based on which player wins the second set of the Marta Kostyuk vs Sloane Stephens match in the 2026 WTA Cincinnati Round of 32. If the match does not occur before any play due to injury, walkover, forfeiture, or cancellation, it resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes within two weeks. If a player retires during the match, markets that can be settled based on completed play will resolve accordingly, while unresolved markets will settle at a fair market price determined by the Exchange. Kalshi is not affiliated with the governing league, and all trademarks remain property of their respective owners.
