These markets evaluate how long a specific tennis match will last by counting the total number of games played. Each market has a different threshold for the number of games needed to settle as 'Yes'. The outcomes depend entirely on the final game count from the match, with specific procedures for handling cancellations, delays, or retirements.
The official rules for these markets govern the settlement of bets based on the total number of games completed in the Ben Shelton vs Tallon Griekspoor professional tennis match at the 2026 US Open Men Singles Round Of 128. Each market corresponds to a specific game threshold (over 33.5, over 38.5, or over 43.5 games), resolving to 'Yes' if the full match exceeds that threshold. If the match does not commence due to injury, walkover, forfeiture, or cancellation before any ball is played, all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with settlement occurring within two weeks after completion. In the event of a player retirement during the match, markets that can be definitively settled based on games already played will do so, while any unresolved markets will settle at a Fair Market Price determined solely by the Exchange. These rules apply uniformly across all three markets, ensuring consistent handling of contingencies while maintaining clarity in final resolution.
