This market tracks the outcome of the first set in a professional tennis match between Martin Landaluce and Jacob Fearnley at the 2026 US Open. It determines which player will claim victory in that initial set, reflecting the competitive dynamics of their early encounter. The result captures the immediate performance and strategy of both athletes in the opening stage of the match.
The market resolves based on which player wins the first set of the Martin Landaluce vs Jacob Fearnley match in 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, with settlement occurring within two weeks after the match finishes. In cases of retirement during the match, any markets that can be definitively settled based on completed play will do so, while unresolved markets will settle at a fair market price determined by the Exchange. The Exchange retains sole discretion in determining fair prices when necessary, and is not officially affiliated with the governing league.
