2026 Women’s US Open Winner (Tennis) Predictions

Who Will Win the 2026 Women's US Open? Latest Market Odds

The prediction market on Polymarket is pricing odds for the 2026 Women's US Open champion, closing on Sep 13, 2026. Traders are weighing contenders across the current WTA field to forecast who will lift the trophy at Flushing Meadows next year. This market captures real-time sentiment from thousands of participants betting their money on the outcome.

Sabalenka Leads a Crowded Field at 24% Implied Probability

Aryna Sabalenka commands the highest market-implied probability at 24%, reflecting her recent dominance and consistent performance at major tournaments. Behind her, Iga Swiatek sits at 19%, while Elena Rybakina, Mirra Andreeva, and Coco Gauff round out the top tier. The remaining field—including Naomi Osaka, Amanda Anisimova, and Victoria Mboko—each carry smaller implied odds, suggesting the market sees a competitive but concentrated battle for the title.

What Could Shift the 2026 Women's US Open Favorites

Injuries, form swings, and head-to-head results over the coming months will reshape these odds. A major tournament win by an underdog in 2025 or early 2026 could prompt sharp traders to reassess probabilities. Conversely, consistency from top seeds could tighten the market around the current frontrunners. Shifts in player rankings, fitness, and court conditions closer to September will drive movement as the close date approaches.
