**Alcaraz triumphed in New York while Alexander Zverev finished runner-up.**

Carlos Alcaraz captured the men's singles title at the US Open on Sunday 13 September. The victory marked his first triumph at this Grand Slam. He secured the championship in New York.

The final result contradicted those expectations.

The same Thursday record also noted that Alexander Zverev was expected not to claim the title. Those predictions foresaw Zverev's defeat in the event. Zverev did not win the championship.

The tournament concluded with Alcaraz as the sole champion while Zverev finished without the title. The men's singles competition ended with Alcaraz's victory confirmed on Sunday. The 2026 US Open wrapped up with that result.

## Analysis

Alcaraz's US Open win reverses the earlier view that he would fall short, adding a major title to his résumé and enhancing his standing among contemporary champions. The achievement may influence his confidence and perception on the tour, positioning him as a key contender in future Grand Slam events.

Missing the title could affect his ranking trajectory and may shape expectations for his performance in upcoming tournaments.
