Description

A doubles tennis match pits the team of Andreea Herea and Vergara Rivera against Chan and Williams. The result depends entirely on which pair secures the win after play commences. Substitutions or changes to either team's lineup before the match starts invalidate the original contest, splitting the outcome evenly.

Kalshi

This event resolves based on the winning team of the Andreea Herea / Vergara Rivera vs Chan / Williams professional tennis match in the 2026 W35 Santa Fe Round of 16, provided a ball has been played. If the match does not occur before play begins—due to injury, walkover, forfeiture, or cancellation—all markets resolve at $0.50. If any player on either team does not participate, even with a replacement, the event is considered a different match and resolves at $0.50. A withdrawal or forfeiture after the match starts results in that team resolving to No. Postponements or delays keep markets open until the rescheduled match concludes within two weeks.
