Jannik Sinner holds the top ATP ranking and commands the strongest implied probability among men’s contenders for the 2026 US Open final, reflecting his recent hard-court dominance, multiple Masters titles, and Wimbledon momentum heading into the late-summer swing. Carlos Alcaraz, the defending champion, faces uncertainty after a prolonged wrist injury that forced his withdrawal from Cincinnati and limited pre-tournament preparation. On the women’s side, world No. 1 Aryna Sabalenka leads the field on current form and hard-court results, with Elena Rybakina, Coco Gauff, and Iga Swiatek close behind in the WTA standings. Key upcoming variables include official injury reports, draw placement, and any late withdrawals that could alter semifinal or final matchups during the two-week hard-court major.
