This market asks whether Dayana Yastremska will win the 2026 U.S. Open women’s singles title. The U.S. Open is one of tennis’s four major tournaments, so the winner is decided over a long, high-pressure event in New York rather than a single match. Because the field is deep and the tournament is still far away, the question is really whether Yastremska can survive multiple rounds against the top players and finish as champion.
The market settles on the official winner of the 2026 U.S. Open Women’s Singles Tournament. The tournament is scheduled for August 23 through September 13, 2026, and the market is specifically tied to that women’s singles title, not doubles or any other draw. If Yastremska is mathematically or officially eliminated at any point under tournament rules, the market resolves to No; if the event is canceled, pushed past October 31, 2026, or ends without a declared winner, it resolves to Other.
Dayana Yastremska is an established tour player, but winning a Grand Slam requires a title run across seven matches against a full field that usually includes multiple higher-seeded contenders. That creates real uncertainty even for strong players, especially in a tournament where form, draw position, match fitness, and day-to-day execution can matter a lot. The market is pricing the gap between simply being a capable entrant and actually winning one of the hardest titles in tennis.
The biggest price moves would come from Yastremska’s status in the build-up to the tournament: whether she is healthy, playing regularly, and performing well on hard courts, which are the U.S. Open surface. At the event itself, each round matters; a difficult draw, an early upset, or a withdrawal can quickly change the outlook, while a deep run through the second week would make the market more plausible. Official entry lists, seedings, and any confirmed injury or withdrawal news are especially important for a market like this.

View marketThe 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.
Readers should watch the official U.S. Open site for the women’s singles draw, match results, and the final declared champion, since those are the primary settlement signals. It is also worth checking whether Yastremska is still in the draw and advancing, because elimination under tournament rules is enough for the market to resolve No. The main ambiguity risk is timing: if the tournament is delayed or unusual scheduling changes push resolution beyond the stated October 31, 2026 cutoff, the market’s fallback rule matters more than general assumptions about the event calendar.
