In the upcoming US Open ATP singles match between Arthur Gea and Botic van de Zandschulp, scheduled for September 7, 2026 at 11:00AM ET: This market will resolve based on the final set score of the Arthur Gea vs. Botic van de Zandschulp 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 bettors, potentially differing from those set by traditional sportsbooks. Sportsbooks establish lines based on their own modeling and aim to balance action on both sides, while this market is driven purely by traders expressing their beliefs about the probability of each exact score. Discrepancies can arise due to differing information, biases, or simply the dynamics of supply and demand within the prediction market. It's often useful to compare the implied probabilities to see where the market diverges from conventional wisdom.
