The tournament often dubbed the ‘fifth Grand Slam’ would dramatically reshape tennis history if it officially counted alongside the sport’s biggest four.
Indian Wells has long carried the unofficial title of tennis’s “fifth Slam.” But what if the Masters 1000 event in California had actually been elevated to major status, joining the Australian Open, Roland Garros, Wimbledon and the US Open?
The ripple effect would be enormous. The all-time leaderboard would look different, several legends would gain extra majors — and current world number one Carlos Alcaraz would already be much closer to double digits.
Djokovic on 29, Federer and Nadal Level on 25
Novak Djokovic currently owns 24 Grand Slam titles and has lifted the Indian Wells trophy five times. Combine those achievements and he would stand on 29 majors — extending his lead even further at the top of the men’s game.
The order at No.1 would not change, but the margins behind him would. Roger Federer, who won Indian Wells five times, would move from 20 to 25 majors. Rafael Nadal, a three-time champion in the Californian desert, would climb from 22 to 25.
Instead of Nadal sitting alone in second place in reality, Federer and Nadal would be tied on 25.
Further down the list, Pete Sampras would rise from 14 to 16 majors thanks to his two Indian Wells titles. Jimmy Connors would jump from eight to 11, drawing level with Bjorn Borg.
Meanwhile, Carlos Alcaraz — champion at Indian Wells in 2023 and 2024 — would move from seven to nine majors. In this alternate timeline, he would already be knocking on the door of double figures.
Why Indian Wells is called the ‘Fifth Grand Slam’
There are tangible reasons the tournament earns that nickname.
Indian Wells is the most attended event outside the four majors and ranks as the second-largest tennis tournament in the United States, behind only the US Open. It draws full fields from both the ATP and WTA Tours and consistently features blockbuster matchups deep into the fortnight.
The venue itself reinforces that status. The Indian Wells Tennis Garden boasts the second-largest permanent outdoor tennis stadium in the world, with a capacity of 16,100 — behind only Arthur Ashe Stadium in New York (23,771).
Yet its prestige also makes recent champions intriguing in this hypothetical scenario. Since 2020, the men’s singles winners have included Cameron Norrie (2021), Taylor Fritz (2022), Alcaraz (2023, 2024) and Jack Draper (2025). Norrie defeated Nikoloz Basilashvili in the 2021 final, while Draper beat Holger Rune in 2025.
If Indian Wells counted as a Slam, both Norrie and Draper would technically be Grand Slam champions — a reminder that Masters 1000 volatility can differ from the sustained dominance often seen at the four majors.
For now, Indian Wells remains a Masters 1000 event. But imagining it as a fifth Slam offers a fascinating reworking of tennis history — and a reminder of just how much weight the Californian title already carries.
