Alexander Zverev holds overwhelming trader consensus in the 2026 US Open winner market due to his French Open title earlier in the year, strong hard-court form, and favorable draw developments that eliminated top rivals like Jannik Sinner and Carlos Alcaraz before the later stages. The German's serve, backhand consistency, and major-final experience have driven his positioning as the clear leader among remaining contenders. Casper Ruud and others trail far behind given limited recent breakthroughs on the surface. Even at such elevated implied probabilities, late injuries, a surprising semifinal or final upset, or unexpected physical setbacks could still alter the outcome in a best-of-five Grand Slam setting.
