How this market resolves

This market refers to the tennis match between Stefanos Sakellaridis and Christopher O'Connell in the US Open, Qualification ATP, originally scheduled for August 25, 2026 at 11:00AM ET. This market will resolve to "Over" if the total number of sets completed equals or exceeds 3. Otherwise, it will resolve to "Under." A super tie breaker is considered as one (1) set. 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 8, 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 Grand Slam statistics; however, a consensus of credible reporting may also be used.
