This market will resolve to "Yes" if the listed player clinches a spot in the Semifinals at the 2026 US Open per US Open rules. Otherwise, the associated market will resolve to "No". If at any point it becomes impossible for the listed player to clinch a spot in the Semifinals at the 2026 US Open (e.g. the player is eliminated), the associated market will resolve to "No". If the 2026 US Open is cancelled, postponed after September 27, 11:59 PM ET, or the players that qualified for the Semifinals have not been officially confirmed by the USTA within that timeframe, this market will resolve to "No". The resolution source for this market will be official information from the USTA and ATP; however, a consensus of credible reporting may also be used.
