In the upcoming US Open ATP singles match between Alexander Blockx and Flavio Cobolli, scheduled for September 5, 2026 at 11:00AM ET: This market will resolve based on the final set score of the Alexander Blockx vs. Flavio Cobolli 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.
