Kalshi
The market centers on a professional tennis match scheduled for the 2026 WTA Cincinnati Quarterfinal between Coco Gauff and Marta Kostyuk. The outcome hinges on which player wins the match after play has commenced. If the match does not start due to injury, cancellation, or other issues, the market resolves to a fair price instead of a definitive win for either player.
The market resolves based on the winner of the Gauff vs Kostyuk professional tennis match in the 2026 WTA Cincinnati Quarterfinal, provided that at least one ball has been played. If the match does not occur—due to player injury, walkover, forfeiture, or any other cancellation before play begins—the market resolves to a fair price. If the match is postponed or delayed, the market remains open and closes after the rescheduled match concludes, with a two-week window for final resolution.
