Description

This event tracks the total number of games played in a professional tennis match between Katerina Siniakova and Madison Keys during the 2026 WTA Cincinnati Round Of 32. The outcome depends on whether the match lasts longer than specific game thresholds. Various scenarios such as match cancellations, postponements, or retirements are considered in determining the final result.

Kalshi

The event determines whether the total number of completed games in the Katerina Siniakova vs Madison Keys professional tennis match at the 2026 WTA Cincinnati Round Of 32 exceeds specified thresholds (16.5, 21.5, or 26.5 games). If the match does not occur before play begins due to injury, walkover, forfeiture, or cancellation, all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes within two weeks. In the event of a retirement, markets that can be settled based on completed play resolve accordingly, while unresolved markets settle at a Fair Market Price determined by the Exchange.
