This market focuses on predicting whether a tennis match at the 2026 US Open Men Singles Quarterfinal will conclude with a decisive victory for either player, defined as winning by more than one and a half sets. The outcome hinges on the margin of victory rather than just who wins the match. Any disruptions such as injuries, cancellations, or retirements trigger specific resolution procedures, ensuring fairness even when the match does not proceed as scheduled.
The event determines whether either Karen Khachanov or Alexander Blockx will win the 2026 US Open Men Singles Quarterfinal match by a margin of more than 1.5 sets. If Khachanov achieves this, the first market resolves to Yes; if Blockx does, the second market resolves to Yes. Should the match not occur before play begins—due to injury, walkover, forfeiture, or cancellation—it resolves to a fair price. Postponements keep markets open until the rescheduled match concludes, with settlements within two weeks. If a player retires, markets based on completed play settle definitively, while unresolved markets resolve to a Fair Market Price at the Exchange’s discretion.
