Jannik Sinner leads the 2026 US Open market at 51.5% implied probability due to his dominant 2026 campaign, including a Wimbledon title defense and a 44-3 record across multiple Masters 1000 titles on varied surfaces. Alexander Zverev sits at 13.3% after capturing his first major at Roland Garros and reaching the Wimbledon final, highlighting improved consistency in big matches. Carlos Alcaraz holds 12.0% as defending champion but faces uncertainty from a right wrist injury that has sidelined him since April, limiting recent hard-court preparation. Novak Djokovic at 6.3% reflects veteran Grand Slam experience tempered by age-related form questions, while younger players like Ben Shelton and Taylor Fritz occupy lower shares based on hard-court results and ranking trajectories. Hard-court conditions and recent head-to-head patterns among the top three further shape trader consensus around these probabilities.
