In the upcoming US Open ATP singles match between Daniil Medvedev and Frances Tiafoe, scheduled for September 6, 2026 at 11:00AM ET: This market will resolve based on the final set score of the Daniil Medvedev vs. Frances Tiafoe 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.

Generally, prediction market odds often reflect a 'wisdom of the crowd' that can differ from traditional sportsbook lines. Sportsbooks set odds based on their own models and risk assessment, while this market aggregates the opinions of many individual traders. It’s common to see discrepancies, especially when there’s significant public interest or disagreement about the likely outcome. These differences can present opportunities for arbitrage, where traders attempt to profit from the price variations between Polymarket and sportsbooks. However, it’s important to note that both represent probabilities of an event occurring.
On Polymarket, this market is priced through a continuous auction mechanism where traders buy and sell shares representing their belief in the probability of different exact scores. The price of each share directly corresponds to the implied probability of that outcome. On Polymarket, prices reflect that venue's order book, liquidity, and how traders price the outcome right now. As more traders participate and new information emerges, the prices adjust to reflect the collective assessment of the event’s likelihood. Higher trading volume generally indicates greater confidence and agreement among traders regarding specific outcomes in the Medvedev vs. Tiafoe match.
This market resolves around Sep 13, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The exact score of the Medvedev vs. Tiafoe match, as officially recorded by the tournament organizers, will determine the winning share(s) in this market. Resolution will occur after the completion of the match and the official results are published. Traders should monitor official sources for the final score to understand when this market will be settled and payouts will be distributed.
Several signals could significantly influence this market. Any news regarding player injuries, changes in playing conditions, or even pre-match interviews expressing confidence or concern could shift trader sentiment. Unexpected results in other matches leading up to the Medvedev vs. Tiafoe match might also affect perceptions of player form and momentum. Furthermore, major shifts in public opinion, as reflected in polls or media coverage, could drive trading activity and alter the prices on Polymarket. A strong performance by either player in a preceding round would likely be a key catalyst.
