Market analysis

Polymarket prices Sabalenka at 57% to win, reflecting her status as two-time defending champion and top seed pursuing a three-peat, despite just losing her world No. 1 ranking to Rybakina this week. Rybakina's 22% probability sits comfortably ahead of Gauff (20%) and reflects the Kazakhstani's recent surge—she beat world No. 1 Zheng in the quarterfinals and has a recent head-to-head edge over Gauff from their Toronto semifinal last month. All four finalists face semifinals Thursday night, with Sabalenka-Pegula followed by the Rybakina-Gauff semifinal.
