Description

This market focuses on predicting which player will win the first set of a professional tennis match between Martin Landaluce and Matteo Arnaldi at the 2026 ATP Cincinnati Round Of 64. The outcome depends solely on the result of the first set, regardless of the overall match result. Bettors are assessing each player's early-game performance and strategies in this specific encounter.

Kalshi

The market resolves based on the winner of the first set in the specified professional tennis match. 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 keep the market open until the rescheduled match concludes, with settlement occurring within two weeks. If a player retires during the match, markets can resolve based on completed play; otherwise, unresolved markets settle at a fair market price determined by the Exchange. Kalshi disclaims any official affiliation with the governing league, and all trademarks remain property of their respective owners.
