This market will resolve to "Yes" if the listed player clinches a spot in the Final at the 2026 US Open per US Open rules. Otherwise, the associated market will resolve to "No". If at any point it becomes impossible for the listed player to clinch a spot in the Final at the 2026 US Open (e.g. the player is eliminated), the associated market will resolve to "No". If the 2026 US Open is cancelled, postponed after September 27, 11:59 PM ET, or the players that qualified for the Final have not been officially confirmed by the USTA within that timeframe, this market will resolve to "No". The resolution source for this market will be official information from the USTA and WTA; however, a consensus of credible reporting may also be used.

On Polymarket, this market reflects trader sentiment through dynamic pricing, while sportsbooks use their own models incorporating historical data and expert analysis. Prediction markets often react faster to breaking news and shifting public opinion, potentially offering different implied probabilities than traditional sportsbook lines. The gap can widen during periods of high volatility or when unique insights emerge within the trading community. Traders should compare both sources to identify potential value differences.
This market resolves around Sep 11, 2026, with the outcome confirmed once the event is verifiable from credible public reporting. The final will be determined by tournament results, and the market will settle based on which player actually reaches that stage, closing all contracts accordingly.
