This market refers to the tennis match between Daniel Altmaier and Ignacio Buse in the Winston-Salem Open, originally scheduled for August 26, 2026 at 2:00PM ET. This market will resolve to "Over" if the total number of games completed in the first set equals or exceeds 9. 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 September 9, 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.
