This set of markets evaluates the performance difference between Matteo Arnaldi and James Duckworth in their upcoming tennis match at the 2026 US Open. Each market assesses whether the game differential in favor of a specific player meets or exceeds a predetermined threshold. The outcomes hinge on the final score of the match, reflecting the competitive balance between the two athletes.
The markets collectively assess the game differential between Matteo Arnaldi and James Duckworth in their 2026 US Open Men Singles Round Of 128 match. Each market resolves based on whether the differential in favor of the specified player exceeds a set threshold (-4.5, -1.5, or +1.5 games). If the match does not commence due to injury, walkover, forfeiture, or cancellation, all markets resolve to a fair price. Postponements or delays keep markets open until the rescheduled match concludes, with settlements occurring within two weeks. In cases of retirement, markets with sufficient data to determine outcomes will resolve accordingly, while unresolved markets will settle at a Fair Market Price determined by the Exchange.
