US Open 2026 (Men's Singles): Alexander Zverev (GER, seeded No. 1) wins the tournament (final September 13/14, 2026, USTA Billie Jean King National Tennis Center, confirmed by USTA or ATP)

Jannik Sinner (ATP No. 1) has withdrawn from the 2026 US Open due to a knee injury, making Zverev the No. 1 seed (tennis365.com, August 2026). Zverev is already predicted to reach the US Open 2026 quarterfinal (open prediction). As No. 1 seed, he avoids the most dangerous opponents until the late stages of the draw. Djokovic (SRB, No. 4, also predicted for QF) is historically strong at Slams but is 39. Carlos Alcaraz (No. 2) is only predicted to reach the 3rd round per the open prediction. Without Sinner and with Alcaraz as an early-exit risk, Zverev's title chances increase significantly. Aggregated bookmaker odds imply Zverev ~30–34% tournament win probability. Polymarket sees Zverev at approximately 29% per last available data.
