Roger Federer spent over two decades dominating tennis courts around the world. He racked up 20 Grand Slam titles, stayed ranked World No. 1 for 310 weeks, and pocketed close to $131 million in prize money alone.
But here’s the surprising part: none of that prize money is what made him a billionaire.
Federer didn’t cross the billion-dollar mark while he was still playing. He got there years after retirement, thanks to one bold decision that had nothing to do with match wins or trophies. It all started with a smart bet on a small, lesser-known Swiss shoe brand.
Let’s break down exactly how it happened.
Saying Goodbye to Nike
Federer wore Nike gear for almost his entire career. He started as a teenager and stuck with the brand for about 20 years, becoming one of its most recognizable faces in sports.
During that long partnership, Nike reportedly paid Federer around $150 million total, with his yearly paycheck climbing above $10 million in his final seasons with the brand.
Then, in 2018, everything changed.
By that point, Federer was nearing his 37th birthday. Most athletes at that age would expect their earning power to shrink, not grow. But Federer’s next move flipped that expectation completely upside down.
A Deal Too Good to Refuse
Japanese clothing company Uniqlo stepped in with a jaw-dropping offer: $300 million spread across 10 years.
That works out to about $30 million a year — nearly double what Nike had paid him during their entire two-decade run together.
There was another twist, too. The deal guaranteed Federer his full payout even if he retired early. And that’s exactly what happened — he played his last match in 2022, just four years into the contract. Uniqlo kept paying him anyway, well into his retirement.
One important detail made this deal even more interesting: Uniqlo only covered clothing, not shoes. Since the brand didn’t make tennis footwear, Federer was free to sign a separate deal for his sneakers.
Instead of chasing another big paycheck, Federer decided to try something far more ambitious.
How a Small Swiss Brand Changed Everything
Federer’s connection to the running shoe brand On actually started at home. His wife, Mirka, had been wearing the shoes and loved them.
At the time, On was still a small company. Founded in Zurich back in 2010, it had built a loyal fan base among runners but was nowhere near as big as giants like Nike or Adidas.
Federer reached out to the founders, and instead of asking for a standard endorsement check, he made a much bigger move.
Betting on Ownership, Not Just a Paycheck
In 2019, Federer bought an equity stake in On. Rather than just lending his name to the brand, he rolled up his sleeves and helped design products, including a signature tennis shoe line called “The Roger.”
Two years later, On went public on the New York Stock Exchange — and that’s when Federer’s bet really started to pay off.
From Millions to Billions
Federer’s exact ownership percentage in On has never been officially confirmed, but experts estimate it at around 3%.
Here’s why that number matters so much: On’s market value today sits at roughly $12.4 billion. A 3% stake at that valuation would be worth about $372 million — nearly three times what Federer earned in prize money across his entire tennis career.
And at one point, it was worth even more. Back in May 2025, On’s market cap briefly touched close to $20 billion. At that peak, Federer’s stake would have been worth around $600 million.
Beyond Shoes: Federer’s Other Big Bets
On wasn’t Federer’s only smart investment.
Back in 2013, he teamed up with his longtime agent, Tony Godsick, to launch Team8, a sports management company. The goal was to give Federer more say over his own endorsements and business future.
Team8 later helped create the Laver Cup, a team tennis event that pits Europe against the rest of the world. Since launching in 2017, the tournament has grown into an officially recognized ATP Tour event, packed with star players and big sponsors. Federer still holds a stake in it today, letting him earn from tennis without stepping onto the court himself.
Federer also joined a $235 million funding round in 2021 for NotCo, a Chilean company that uses artificial intelligence to build plant-based food products. That round valued the company at $1.5 billion, and Federer wasn’t the only famous name involved — Formula One champion Lewis Hamilton and musician Questlove also invested.
The size of Federer’s stake in NotCo hasn’t been made public. But the strategy behind it looks familiar: instead of just cashing endorsement checks, Federer kept turning his fame into ownership.
Crossing the Billion-Dollar Mark
When Federer played his final match in September 2022, his net worth was estimated at $550 million.
Fast forward almost exactly four years, and that number has nearly doubled — Roger Federer is now worth an estimated $1 billion.
That puts him in some elite company among athlete billionaires:
- Lionel Messi — $1 billion
- Cristiano Ronaldo — $1.2 billion
- Tiger Woods — $1.3 billion
- Magic Johnson — $1.6 billion
- Ion Tiriac — $2.4 billion
- Michael Jordan — $3.6 billion
The Real Lesson Behind Federer’s Fortune
Federer’s story follows a pattern seen again and again among the world’s wealthiest athletes and celebrities: salaries and endorsement checks rarely build billion-dollar fortunes on their own.
Ownership is what does it.
By trading a simple paycheck for a piece of a growing company, Federer didn’t just cash in on his fame — he built lasting wealth that kept growing long after he hung up his racket.
