Description

This market refers to the tennis match between Ben Shelton and Carlos Alcaraz in the US Open ATP, originally scheduled for September 8, 2026 at 11:30AM ET. This market will resolve to "Over" if the total number of games completed in set 4 equals or exceeds 9. Otherwise, it will resolve to "Under." Any tiebreak in set 4 counts as one (1) game toward the total. If set 4 begins but is not completed, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. An outcome is considered determined if it would have been guaranteed had the set been played to completion using the minimum number of additional games required. For example, for a line of 9.5, if play stops with set 4 at 5-4, completing the set would have required at least 1 additional game, resulting in at least 10 games played, so "Over" would resolve as the winning outcome. If the match ends before set 4 is reached, this market will resolve 50-50. If the match is canceled before play begins, or play has not begun by September 22, 2026, 11:59 PM ET (14 days after the scheduled start), this market will also resolve 50-50. Resolution will be based on official Grand Slam results.
