Description

This market focuses on the outcome of a specific tennis doubles match at the 2026 US Open. It tracks whether one team wins over the other in their Round of 64 encounter. The result is determined only if the match actually begins play.

Kalshi

The market resolves based on the winner of the Marcinko / Oliynykova versus Dart / Lumsden professional tennis match in the 2026 US Open Women’s Doubles Round of 64, provided that at least one ball is played. If the match does not occur due to injury, walkover, forfeiture, or any other cancellation before play begins, the market resolves to a fair price. Postponements or delays do not immediately close the market; it remains open and closes after the rescheduled match concludes, with a two-week window for final resolution. Kalshi explicitly disclaims any official affiliation with the governing league, and all trademarks remain the property of their respective owners.
