The battle for the ATP year-end No.1 ranking in 2025 has reached its climax at the Nitto ATP Finals in Turin, where Carlos Alcaraz and Jannik Sinner are locked in a thrilling race for supremacy. With both players having dominated the season—Alcaraz with his Grand Slam consistency and Sinner with his late-season surge—the final tournament of the year will determine who finishes as the world’s top-ranked player.
As of November 8, 2025, Jannik Sinner holds the No.1 spot with 11,500 points, having reclaimed it after winning the Paris Masters. Carlos Alcaraz trails closely with 11,250 points, but due to the ATP’s ranking system, the Spaniard is poised to regain the top position next week when points from last year’s Finals are dropped. However, to officially end the year as No.1, Alcaraz must outperform Sinner in Turin.
🧠 Key Scenarios for Carlos Alcaraz to Finish as Year-End No.1
| Scenario | Outcome for Alcaraz | Impact on Ranking |
