Description

Another set of doubles teams face off in the 2026 US Open Women Doubles Quarterfinal. The result is determined by which duo claims victory after the match begins, with special provisions for match disruptions or rescheduling.

Kalshi

The market resolves based on the winner of the Hsieh S-W / Ostapenko vs Mertens / Shnaider professional tennis match in the 2026 US Open Women Doubles Quarterfinal, provided a ball has been played. If the match does not occur due to injury, walkover, forfeiture, or other cancellation before play starts, the market resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes within two weeks. Kalshi is not affiliated with the governing league, and all trademarks belong to their respective owners.
