This market focuses on determining which player will win the first set of a professional tennis match between Alexander Blockx and Flavio Cobolli at the 2026 ATP Cincinnati Round Of 32. The outcome depends solely on the performance of the players during the initial set of the match. If neither player wins the first set because the match is canceled or interrupted before a winner is decided, the market will resolve according to specific fairness guidelines.
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 a two-week window for closure. If a player retires during the match, markets that can be settled based on completed play will resolve accordingly, while unresolved markets settle at a fair market price determined by the Exchange. The Exchange disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
