In the upcoming US Open ATP singles match between Ben Shelton and Carlos Alcaraz, scheduled for September 8, 2026 at 11:30AM ET: This market will resolve based on the final set score of the Ben Shelton vs. Carlos Alcaraz 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.

Prediction market odds often reflect the collective wisdom of a diverse group of traders, which can differ from sportsbook odds that are set by professional oddsmakers. Sportsbooks may incorporate factors like public betting patterns and risk management into their pricing, while this market is driven purely by individuals’ beliefs about the likelihood of each exact score. It’s common to see discrepancies, especially before significant events or when new information emerges. Comparing the two can provide a broader perspective on the potential outcome of the Alcaraz vs. Shelton match.
