The withdrawal of world No. 1 Jannik Sinner with a lingering right knee injury has reshaped the men’s singles draw at the 2026 US Open, elevating Alexander Zverev to the top seed while positioning defending champion Carlos Alcaraz (returning from a four-month right wrist absence) as the clear favorite in trader consensus. Qualifying rounds underway through August 27 will finalize the main draw field ahead of first-round action starting August 30 on outdoor hard courts at Flushing Meadows. Key variables include Alcaraz’s match readiness after limited competitive play, Zverev’s recent form, Novak Djokovic’s veteran experience, and any further injury or fatigue issues among seeds. Bracket placement and early-round matchups will determine paths to the round of 16 on September 6–7, with the wisdom of crowds reflecting these uncertainties in implied probabilities.
