This market will resolve to 'Alexander Maarten Jong Sander Jong' if Alexander Maarten Jong Sander Jong advances against Luca Wiedenmann. This market will resolve to 'Luca Wiedenmann' if Luca Wiedenmann advances against Alexander Maarten Jong Sander Jong. If the match is canceled (not played at all), ends in a tie, or a winner has not been determined by September 11, 2026, 11:59 PM ET (14 days after the scheduled start), this market will resolve to 50-50. If the match begins but is not completed, and one player advances due to the opponent's retirement, default, or disqualification, this market will resolve to the player who advances. If the match ends in a walkover (player withdraws before the start and the other advances automatically), this market will resolve to 50-50. The primary resolution source will be official information from the International Tennis Federation (ITF). A consensus of credible reporting may also be used.
The market resolves based on which player wins the second set of the designated professional tennis match. If the match fails to commence due to injury, walkover, forfeiture, or cancellation prior to any play, it resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes, with a two-week window for closure. If a player retires during the match, markets determinable from completed play settle accordingly, while unresolved markets resolve to a fair market price at the Exchange’s discretion.
