This event tracks the outcome of a professional tennis match in the 2026 US Open Women’s Doubles Round of 64, focusing on which of the two competing teams will claim victory. The match features two pairs of players, and the result depends solely on the performance during the contest. Any changes to the match schedule or cancellations prior to play will follow specific resolution guidelines.
The event determines whether Miyu Kato / Fang-Hsien Wu or Tereza Mihalikova / Olivia Nicholls will win their designated US Open Women’s Doubles Round of 64 match in 2026, provided the match actually begins. If the match is canceled before any ball is played—due to injury, walkover, forfeiture, or other reasons—the market resolves to a fair price. Postponements or delays do not close the market; it remains open until the rescheduled match concludes, with a closure window of two weeks after the new match ends. The market is unaffiliated with the governing tennis league, and all trademarks remain property of their respective owners.
