This market asks whether Sofia Kenin will win the 2026 U.S. Open women’s singles title. The U.S. Open is one of tennis’s four major championships, so the outcome depends on a full two-week Grand Slam draw rather than a single match or ranking snapshot.
The question is simple: will Sofia Kenin emerge as the champion of the 2026 Women’s Singles Tournament at the U.S. Open, which is scheduled for August 23 through September 13, 2026. Settlement follows the tournament’s official winner, and the market can also resolve to “No” if Kenin is eliminated in a way that makes her victory impossible under the event rules, or to “Other” if the tournament is canceled, delayed past October 31, 2026, or ends without a declared winner.
Kenin is a proven major-level player, but winning a Grand Slam requires surviving seven rounds against a deep field, often over several days and in changing conditions. That creates genuine uncertainty around form, fitness, draw position, and whether she can navigate the full women’s singles bracket all the way to the trophy.
The biggest price movers before and during the tournament will be Kenin’s entry status, draw placement, and any official updates on injury, withdrawal, or retirement. Match results matter at every stage: a tough early draw, a loss to a higher-ranked opponent, or a late run into the second week would all change the market’s view quickly, as would any change in the tournament schedule or format.
The current market price implies roughly a 0% chance for the leading outcome, based on live Polymarket pricing. That number is not a prediction from PredictionNinja and it is not a guarantee; it is the current crowd-priced view of the market and can change quickly when new information appears.

View marketThe key source of truth is the official U.S. Open winner announcement, with credible consensus reporting used only if needed. Readers should check that the tournament is still scheduled to finish by September 13, 2026, and note the market’s special fallback rules for cancellation, long postponement, or no declared champion. Because settlement depends on official tournament rules and the final women’s singles result, any walkover, retirement, or disqualification should be interpreted in line with the event’s own scoring and winner-declaration procedures.
