How this market resolves

This market refers to the tennis match between Pierre-Hugues Herbert and Quinn Vandecasteele in the Winston-Salem Open, Qualification, originally scheduled for August 23, 2026 at 1:00PM ET. This market will resolve to "Over" if the total number of games completed equals or exceeds 24. Otherwise, it will resolve to "Under." All tiebreaks, including any Champions/Super tiebreak, count as one (1) game. If the match is postponed or suspended, this market will remain open until the match has been completed. A postponement alone will not trigger a 50-50 resolution. If the match is permanently abandoned before completion, or if the match has not been completed by September 6, 2026, 11:59 PM ET, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. The primary resolution source for this market will be official ATP statistics; however, a consensus of credible reporting may also be used.
