Description

Two tennis players will compete in a professional match where one must secure a victory after play has commenced. The outcome hinges solely on which athlete claims the win, provided the match actually begins.

Kalshi

The market resolves to Yes if the specified player wins the designated WTA Washington Quarterfinal match after at least one ball has been played. If the match does not occur before play begins 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. Kalshi disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
