Description

This market focuses on predicting which player will win the first set in an upcoming professional tennis match. It allows participants to bet on the performance of either competitor in the initial portion of the contest. The outcome depends solely on the result of the first set, regardless of how the overall match proceeds.

Kalshi

The market resolves based on which player wins the first set of the Jelena Ostapenko vs Taylah Preston professional tennis match in the 2026 WTA Seoul Round Of 16. If the match does not occur before any play due to injury, walkover, forfeiture, or cancellation, the market 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 can resolve based on completed play; otherwise, unresolved markets settle at a Fair Market Price determined by the Exchange. Kalshi is not affiliated with the governing league, and all trademarks belong to their respective owners.
