This market tracks the outcome of the first set in a professional tennis match between Mattia Bellucci and Zsombor Piros at the 2026 US Open. It determines which player will claim victory in that initial set, reflecting the competitive dynamics of their early encounter on the court.
The market resolves based on the winner of the first set in the Mattia Bellucci vs Zsombor Piros match during the 2026 US Open Men Singles Round of 128. If the match does not 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 within two weeks. In cases of retirement during the match, outcomes determinable from completed play are settled accordingly, while unresolved markets are priced fairly at the Exchange’s discretion. Kalshi disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
