How this market resolves

This market refers to the tennis match between Goncalo Marques and Andrea Colombo in the ITF M25 Idanha-a-Nova 2 Men, originally scheduled for August 22, 2026 at 6:00AM ET. This market will resolve to "Over" if the total number of games completed equals or exceeds 22. 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 5, 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 ITF statistics; however, a consensus of credible reporting may also be used.
