Roger Federer is officially a billionaire, becoming the first tennis player to reach the milestone through a mix of Grand Slam dominance, lifetime endorsement deals, and a winning sneaker investment.

According to Bloomberg’s Billionaires Index, Federer’s net worth has reached an estimated $1.3 billion. Only a fraction of that came from prize money — $130.6 million over his 24-year career — with the vast majority stemming from sponsorships and smart investments, most notably his early stake in Swiss performance footwear brand On.

The 20-time Grand Slam winner now joins the likes of Michael Jordan and LeBron James as one of the few athletes to reach billionaire status. The On IPO, which pushed the brand’s valuation close to $17 billion, is said to have netted Federer upwards of $500 million for his 3% stake.

Federer’s business playbook is marked by longevity and restraint. His deals with Rolex, Lindt, Credit Suisse, and most famously, Uniqlo — which signed him to a $300 million deal in 2018 with no requirement to keep playing — show how he’s become one of the most bankable personalities in global sport. Unlike Nike, Uniqlo didn’t make shoes, leaving Federer free to back On and co-design his own line.

His management company, Team8, which also co-founded the Laver Cup, has pivoted more into investments and event management after briefly representing rising tennis stars like Coco Gauff.

Federer has remained selective in his post-retirement exposure, resisting a move into punditry or overexposed brand work. Recent public appearances include launching a new clothing line in Paris and waving the French flag at the 2025 Le Mans.

With Wimbledon around the corner, the 42-year-old legend seems to be settling into his next era with the same precision that defined his game — quiet, calculated, and a step ahead of the competition.
