These markets assess the expected performance difference between Stefanos Sakellaridis and Christopher O'Connell in their 2026 US Open Men Singles Round Of 128 match. Each market specifies a different threshold for the game differential, determining whether one player is expected to dominate the other by a certain margin. Outcomes are based on the full match result, with specific handling for match disruptions.
The markets evaluate whether Christopher O'Connell or Stefanos Sakellaridis will win the match by a specified game differential. A 'Yes' outcome occurs if the differential exceeds the stated threshold in favor of the specified player. If the match does not commence due to injury, walkover, forfeiture, or cancellation, all markets resolve to a fair price. Postponements keep markets open until the rescheduled match concludes, with settlements within two weeks. In cases of retirement, markets that can be settled based on completed play do so unconditionally, while unresolved markets settle at fair market value determined by the Exchange.
