In the upcoming US Open ATP singles match between Yibing Wu and Carlos Alcaraz, scheduled for September 4, 2026 at 11:00AM ET: This market will resolve based on the final set score of the Yibing Wu 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.

Typically, prediction market odds reflect the wisdom of the crowd and can differ from traditional sportsbook odds. Sportsbooks often set initial lines to balance action, while this market allows traders to freely adjust probabilities based on their own analysis and information. If there's a significant discrepancy, it might indicate that the market believes the sportsbook has mispriced the event, or that the market has access to information not yet reflected in sportsbook lines. It's important to compare both to gain a comprehensive understanding of potential outcomes for this match.
On Polymarket, this market is priced through a continuous auction mechanism. Traders buy and sell shares representing different exact score outcomes for the Alcaraz vs. Wu match. The price of each share reflects the market's current assessment of the 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 participate and new information becomes available, the prices adjust dynamically, providing a real-time estimate of the likelihood of each result. The market's overall volume indicates the level of interest and confidence in the various possibilities.
This market resolves around Sep 11, 2026, with the outcome confirmed once the final score of the Alcaraz vs. Wu match is verifiable from credible public reporting. The exact score determined by official tournament results will be used to determine the winning outcome in this market. The resolution process relies on publicly available and independently verifiable data, ensuring a transparent and objective outcome. Traders will be able to view the resolution details on Polymarket once the event has concluded.
Several factors could influence the probabilities in this market. Any news regarding player injuries, changes in playing conditions (like court surface or weather), or updated match analysis from tennis experts could all shift trader sentiment. Unexpected results in other matches involving these players, or even broader shifts in public perception of their form, could also lead to price movements. Major upsets in other tournaments or significant tactical adjustments announced by either player are potential catalysts that could impact this market before Sep 11, 2026.
