Description

This event tracks the outcome of a professional tennis match between two pairs of players competing in a semifinal round. The result depends on which team emerges victorious after the match officially begins. If the match does not start due to cancellations, the outcome will adjust fairly based on circumstances.

Kalshi

The event determines whether either of the two competing pairs wins the professional tennis match in the 2026 ATP Winston Salem Semifinal, provided that play has commenced. If the match does not start—due to injury, walkover, forfeiture, or other cancellation—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 deadline of two weeks after the new match date. The outcome is strictly contingent on a ball being played; otherwise, no resolution occurs based on pre-match events.
