**Carlos Alcaraz leads the 2026 US Open winner market at 31.5% implied probability after world No. 1 Jannik Sinner withdrew with a right knee injury that sidelined him from Montreal and Cincinnati.** As the defending champion returning from a four-month wrist absence, Alcaraz benefits from strong hard-court pedigree and recent ATP ranking gains that placed him at No. 2. Alexander Zverev sits second at 19.7% on the strength of his 2026 French Open title and consistent Grand Slam final appearances, positioning him as the top seed in Sinner’s absence. Novak Djokovic holds third at 10.8%, leveraging his experience, hard-court record, and pursuit of a record 25th major. Younger contenders including Ben Shelton (7.4%), Arthur Fils (6.9%), and Taylor Fritz (5.5%) reflect solid recent form and depth in the post-Sinner field, while the overall pricing captures trader consensus on these verified developments ahead of the late-August main draw.
