How this market resolves

This market refers to the tennis match between Tristan Boyer and Spencer Johnson in the San Diego 2, originally scheduled for September 22, 2026 at 5:00PM ET. This market will resolve to "Over" if the total number of games completed in the first set equals or exceeds 10. Otherwise, it will resolve to "Under." Any first-set tiebreak counts as one (1) game. If the match is postponed or suspended, this market will remain open until the first set has been completed. A postponement alone will not trigger a 50-50 resolution. If the match is permanently abandoned before the first set is completed, or if the first set has not been completed by October 6, 2026, 11:59 PM ET, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. An outcome is considered unconditionally determined if it would have been guaranteed under every possible completion of the set played according to the match format published by the tournament organizer for that round, including whether the set is decided by a tiebreak. For example, for a line of 9.5, if play stops with the first set 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. The primary resolution source for this market will be official Challenger statistics; however, a consensus of credible reporting may also be used.
