This event tracks whether either tennis player wins their match by more than one and a half sets, reflecting potential dominance in a head-to-head contest at a major tournament. The outcome depends on the margin of victory should either athlete claim the match. Settlement accounts for match disruptions such as cancellations, postponements, or retirements.
The event determines whether Ben Shelton or Stefanos Tsitsipas wins their 2026 US Open Men Singles Round Of 16 match by more than 1.5 sets. If Shelton achieves this, the 'Ben Shelton wins by over 1.5 sets' market resolves to Yes. Similarly, if Tsitsipas wins by more than 1.5 sets, the 'Stefanos Tsitsipas wins by over 1.5 sets' market resolves to Yes. If the match does not occur before play begins—due to injury, walkover, forfeiture, or cancellation—it resolves to a fair price. Postponements keep the market open until the rescheduled match concludes, with settlement within two weeks after completion. If a player retires during the match, markets that can be settled based on completed play resolve accordingly, while unresolved markets settle at Fair Market Price, determined solely by the Exchange.
