Description

Two teams compete in a professional tennis match where the winner is determined by the match's outcome after play has begun. The market resolves based on which pair wins the contest, with specific conditions for match cancellations or postponements.

Kalshi

The market resolves to Yes if the specified team pair wins the Joint / Xu vs Piter / Tjen professional tennis match in the 2026 WTA Monterrey Quarterfinal after a ball has been played. If the match does not occur due to injury, walkover, forfeiture, or 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 within two weeks. The outcome is determined solely by the match result after play has started, with no affiliation to the governing league.
