Kalshi
This market focuses on predicting whether a specific tennis match will extend beyond a certain number of sets. Bettors assess the competitive nature and potential endurance of the players to determine if the match will last longer than expected. The outcome depends on the actual progression of the match, reflecting strategic and physical aspects of the game.
The markets resolve to Yes if the specified number of sets (either over 3.5 or over 4.5) are played in the Alex Michelsen vs Daniel Merida professional tennis match at the 2026 US Open Men Singles Round Of 32. If the match does not occur before any play due to injury, walkover, forfeiture, or cancellation, it resolves to a fair price. Postponements or delays keep the market open until the rescheduled match concludes, with resolution within two weeks. If a player retires, markets can resolve based on completed play; otherwise, unresolved markets settle at a Fair Market Price determined by the Exchange.
