In the upcoming US Open ATP singles match between Alexander Zverev and Botic van de Zandschulp, scheduled for September 9, 2026 at 11:30AM ET: This market will resolve based on the final set score of the Alexander Zverev 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 forecasters, and can sometimes differ from those offered by traditional sportsbooks. Sportsbooks set their odds based on their own models and to balance their risk, while this market is driven purely by supply and demand among traders. Discrepancies can arise due to differing information, biases, or simply the unique dynamics of each venue. It’s common to see prediction markets incorporate information faster than sportsbooks, especially in response to breaking news or late-developing insights about the players.
On Polymarket, this market is priced through a continuous auction mechanism, where traders buy and sell shares representing their belief in each possible outcome of the Zverev vs. van de Zandschulp match. The price of a share directly corresponds to the implied probability of that outcome occurring. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders buy shares in a particular outcome, its price increases, and vice versa. This dynamic pricing ensures that the market reflects the most up-to-date collective prediction of the event’s result.
This market resolves around Sep 16, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The resolution will be based on the official result of the Zverev vs. van de Zandschulp match, specifically the exact score as determined by the official tournament organizers.
