Saved rules excerpt (truncated): This market refers to the tennis match between Gauthier Onclin and Jan-Lennard Struff in the European Open, originally scheduled for October 21, 2026 at 4:00AM 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 a

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 November 4, 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.

If the match is canceled (not played at all), or is delayed beyond 14 days from the scheduled date without completion at 11:59 PM ET, this market will resolve 50-50.
