Kalshi
This market focuses on predicting which player will win the first set of a tennis match between Karen Khachanov and Alexander Blockx at the 2026 US Open Men Singles Quarterfinal. The outcome depends solely on the result of the first set, regardless of the final match result. It reflects the competitive dynamics and early-game performance of both athletes in a high-stakes tournament setting.
The market resolves based on which player wins the first set of the specified professional tennis match. 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 settlement within two weeks. If a player retires during the match, markets that can be settled based on completed play will resolve accordingly, while unresolved markets will settle at a fair market price determined by the Exchange.
