The ATP year-end No. 1 is the player who finishes the season at the top of the PIF ATP Rankings. The honor is presented at the Nitto ATP Finals, and the final rankings of the year are published the Monday after it; in 2025 they came out on 17 November. Through the autumn, though, the ATP points to a different table to show who is winning that race: the PIF ATP Live Race To Turin, which it calls the barometer for the year-end No. 1 battle.
That is why, in October 2026, Alexander Zverev can clinch year-end No. 1 in Shanghai while the ATP says he will not overtake Jannik Sinner in the weekly rankings when they are re-run after the tournament. Both statements are true, and the reason is the difference between the two tables.
Two tables, two time windows
The PIF ATP Rankings are the official world rankings, used for entry and seeding. They run on a rolling 52-week window: each week, the points a player earned at the same week’s events a year earlier come off, and whatever he earns now goes on. In singles a player’s total is built from 18 results plus the Nitto ATP Finals as a 19th: the four Grand Slams, the eight automatic-entry Masters 1000 events and his six best other results, which can include the United Cup, Monte-Carlo, ATP 500s, ATP 250s, Challengers and ITF events.
The Race uses the same points but counts only what has been earned in the current calendar year. It starts at zero in January and decides qualification for Turin: the top seven after the Paris Masters qualify, and the eighth place goes to a current-year Grand Slam champion ranked between eighth and 20th if there is one, according to the ATP.
Early in the season the two tables can look nothing alike, because the rankings still carry most of the previous year. By the time the rankings are run after the season finale, almost all of last year’s results have dropped out of the 52-week window, so the two tables converge. That is why the Race leader at the end of the season is, in practice, the year-end No. 1.
Why the weekly No. 1 and the year-end leader can differ
In October, a player’s ranking still includes his results from the closing weeks of the previous season, while the Race does not. A player who did well last autumn but has stopped playing keeps those points in the rankings until each week rolls round again.
That is the 2026 case. Sinner, who ended his season with a knee injury, is No. 1 in the weekly rankings, but Zverev leads the Race. The ATP has said that whatever happens in Shanghai, Zverev will not move above Sinner when the rankings are re-run after the event. As the remaining weeks of the 2025 calendar come off Sinner’s total and he adds nothing new, the weekly ranking moves toward the Race. Being No. 1 in the Live Rankings mid-week does not count either: the ATP says a player cannot call himself World No. 1 unless he spends at least one week at No. 1 in the published rankings.
How year-end No. 1 is clinched
A player clinches when no rival can catch him in the Race with the points left on the calendar. A Masters 1000 title is worth 1,000 points and an undefeated Nitto ATP Finals champion collects 1,500, so the sums usually stay open into the European indoor season.
The clinch can come from a player’s own result or from rivals losing. In Shanghai in 2026, the ATP set out two routes for Zverev: reach the semifinals, or see Carlos Alcaraz and Ben Shelton both lose at any point in the event. In 2025 it went to the last week. Alcaraz and Sinner arrived in Turin still contesting it, and Alcaraz clinched on 13 November by beating Lorenzo Musetti to go 3-0 in the round robin.
Players have rearranged whole autumns for it. Chasing a sixth straight year-end No. 1 in 1998, Pete Sampras added Basel, Vienna, Lyon, Stuttgart, Paris and Stockholm to his schedule between the US Open and the season finale, according to the ATP. Marcelo Rios, his nearest challenger, did the same; Rios was then hurt at the finale in Hanover, and Sampras learned he had clinched while eating pasta at his hotel.
The records
Nineteen players have finished a season as ATP year-end No. 1 since the rankings began in 1973, ATP chairman Andrea Gaudenzi said in 2025. Novak Djokovic holds the record with eight, in 2011, 2012, 2014, 2015, 2018, 2020, 2021 and 2023, and he owns the three oldest year-end No. 1 finishes, the last at 36. Sampras is second with six, and his six came in a row, from 1993 to 1998, a streak no one else has matched. Jimmy Connors, with five straight from 1974 to 1978, Roger Federer and Rafael Nadal have five each.
At the other end, Alcaraz became the youngest year-end No. 1 in 2022, at 19, after starting that season at No. 32, the biggest rise to the year-end top spot in the rankings’ history. His second finish in 2025 put him alongside Bjorn Borg, Stefan Edberg and Lleyton Hewitt with two, and made him the 11th player to finish No. 1 more than once. Before Alcaraz, Hewitt was the youngest, clinching in 2001 at the finale. The full list of men who have held No. 1 at any point is in our ATP world No. 1 list.
