Saved rules excerpt (truncated): This market refers to the tennis match between Rei Sakamoto and Kasidit Samrej in the Matsuyama, originally scheduled for November 10, 2026 at 7:00PM 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 additional

Saved rules excerpt (truncated): This market refers to the tennis match between Rei Sakamoto and Kasidit Samrej in the Matsuyama, originally scheduled for November 10, 2026 at 7:00PM 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 November 24, 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 match played according to the match format published by the tournament organizer for that round, including whether a final set is played as a full set or as a match tiebreak. For example, for a line of 21.5, if play stops at 6-3, 5-6, completing the match would have required at least 2 addition
