Two professional tennis players will compete in a high-stakes match at the 2026 US Open. The outcome depends on whether the total number of games played exceeds a specific threshold, reflecting the potential length and intensity of the contest.
Each market resolves to Yes if the total completed games in the match exceed the specified threshold (17.5, 22.5, or 27.5 games). If the match does not occur due to injury, walkover, forfeiture, or cancellation before play begins, it resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes. In case of retirement, markets can resolve based on completed play; otherwise, unresolved markets resolve to Fair Market Price at the Exchange's discretion.
