Description

This event tracks the outcome of a professional tennis match in the 2026 WTA Singapore Semifinal featuring two pairs of players. The result depends on which pair emerges victorious after the match begins. If the match does not start due to cancellations, the outcome will be adjusted fairly.

Kalshi

The event determines the winner of the Costoulas / Gibson versus Routliffe / Sutjiadi professional tennis match in the 2026 WTA Singapore Semifinal. If either pair wins the match after play has commenced, the corresponding market resolves to Yes. Should the match fail to start due to injury, walkover, forfeiture, or other cancellations before any ball is played, the market resolves to a fair price. If the match is postponed or delayed, it remains open until the rescheduled match concludes, with a closure window of two weeks following the final result. The event operates independently of the governing league, and all trademarks remain property of their respective owners.
