In the upcoming US Open ATP singles match between Brandon Nakashima and Alex Michelsen, scheduled for September 2, 2026 at 11:00AM ET: This market will resolve based on the final set score of the Brandon Nakashima vs. Alex Michelsen match. This match is played in a best-of-5-sets format. The possible outcomes are 3-0, 3-1, “Not Completed”, and 3-2 in either direction. If the match is canceled (not played at all), or is delayed beyond 14 days from the scheduled date at 11:59 PM ET without completion, this market will resolve to 'Not Completed'. If the match begins but is not completed, and one player advances due to the opponent's retirement, default, or disqualification, this market will resolve to 'Not Completed' regardless of the set score at the time. If the match ends in a walkover (player withdraws before the start and the other advances automatically), this market will resolve to 'Not Completed'. The primary resolution source will be official information from the ATP Tour. A consensus of credible reporting may also be used.

This market resolves around Sep 9, 2026, with the outcome confirmed once the match result is verifiable from credible public reporting. The exact final score reported by accepted sports news sources will determine which trading position cashes out. Timing depends on when official match records become widely and reliably available post-event.
Injuries, weather delays, or changes to player form leading up to the match could shift expectations and move this market. Key moments such as recent performance data, head-to-head history, or unexpected tournament conditions may also influence trader sentiment. Any development that alters the perceived likelihood of specific scorelines can cause rapid price adjustments on Polymarket as participants react.
