This event tracks the outcome of a high-stakes professional tennis match between two top players in a major tournament. The result depends solely on which athlete secures victory after the match officially begins. Any changes to the match schedule or unexpected cancellations are managed through specific fairness guidelines.
The event determines the winner of the professional tennis match between Aryna Sabalenka and Jessica Pegula at the 2026 US Open Women Singles Semifinal, resolving to Yes for the respective market if the designated player wins after play has commenced. If the match fails to start due to injury, walkover, forfeiture, or other cancellations before any ball is played, the market resolves to a fair price. Postponements or delays do not immediately close the market; it remains open and settles after the rescheduled match concludes, with a two-week window for completion. The market is independent of the governing league, and all trademarks remain property of their respective owners.
