Kalshi
This market tracks the outcome of the second set in a professional tennis match between Mattia Bellucci and Zsombor Piros at the 2026 US Open. It focuses specifically on determining which player will claim victory in that particular set. The event is part of the high-stakes singles competition in one of tennis's four major tournaments.
The market resolves based on the winner of the second set in the Mattia Bellucci vs Zsombor Piros match during the 2026 US Open Men Singles Round of 128. If the match fails to commence due to injury, walkover, forfeiture, or cancellation before any play occurs, the market settles at a fair price. Postponements or delays allow the market to remain open until the rescheduled match concludes, with a two-week closure window. In cases of retirement during the match, outcomes determinable from completed play resolve accordingly, while unresolved markets settle at a fair market price determined by the Exchange.
