Description

This market focuses on determining the winner of the second set in a professional tennis match between Katerina Siniakova and Madison Keys. The outcome depends solely on which player claims victory in that specific set during their scheduled encounter. Settlement considers various match disruptions, ensuring fair resolution under different scenarios.

Kalshi

The market resolves based on the winner of the second set in the Katerina Siniakova vs Madison Keys match at the 2026 WTA Cincinnati Round of 32. If the match does not commence due to injury, walkover, forfeiture, or cancellation before any play, the market settles at 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 disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
