Saved rules excerpt (truncated): This market refers to the tennis match between Aidan Mayo and Duncan Chan in the Charlottesville Qualifying, originally scheduled for November 1, 2026 at 3:50PM ET.
If the match is played to completion, this market will resolve to "Over" if the total number of sets played equals or exceeds 3, and to "Under" otherwise. A set counts as played once it has begun, even if it is not played to completion. 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 a player retires, withdraws, is defaulted, or is disqualified, or the match otherwise begins but is not completed, this market will resolve based on any outcome that was already unequivocally determined at the time play stopped. An outcome is considered unequivocally determined if it would have been guaranteed under every possible completion of the match played according to the match format published by the tournament organizer for that round. For example, for a line of 2.5, if play stops with the players at one set each, completing the match would have required at least one

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 November 15, 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 addit

If the match begins but is not completed due to retirement, default, or disqualification, this market will resolve 50-50, unless the outcome of this market has already been unconditionally determined by the completed portion of play under the match format published by the tournament organizer for that round. For example, if the deciding set has begun when the match ends, Duncan Chan can no longer win by 2 or more sets, and this market will resolve to "Aidan Mayo."
If the match is canceled before play begins, or a result has not been determined by November 15, 2026, 11:59 PM ET (14 days after the scheduled start), this market will resolve 50-50.
Resolution will be based on official ATP Tour results.
