Jannik Sinner enters as the clear men's frontrunner for the 2026 US Open final after claiming the world No. 1 ranking and posting an elite hard-court record, including recent Masters 1000 titles, while defending champion Carlos Alcaraz works back from a prolonged wrist injury that sidelined him from Cincinnati. On the women's side, Aryna Sabalenka holds the top ranking and leads betting markets thanks to consistent results across surfaces, with Elena Rybakina, Jessica Pegula, and Coco Gauff close behind in the WTA standings. Key upcoming factors include the remaining hard-court Masters events, where form, rest, and any late injury updates to top seeds will shape draw positioning and semifinal matchups at Flushing Meadows. Trader consensus reflects these established edges alongside the inherent variability of best-of-five and best-of-three knockout formats.
