Two professional tennis pairs compete in the 2026 US Open Mixed Doubles Round Of 16. The outcome depends on which pair claims victory in this high-stakes match after play has officially begun.
The market resolves based on the winner of the Rublev / Andreeva vs Vavassori / Errani professional tennis match in the 2026 US Open Mixed Doubles Round Of 16, provided a ball has been played. If the match does not occur due to injury, walkover, forfeiture, or cancellation before play starts, the market resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes within two weeks.
