Tennis has always produced some of the wealthiest athletes in sport but the numbers at the very top of the list in 2026 have reached a level that would have seemed almost impossible even a decade ago.
Roger Federer became only the second person from the world of professional tennis to cross the billion dollar mark in net worth in late 2025, a milestone that speaks as much to his business brilliance as it does to his extraordinary playing career. But even Federer sits second on this list, behind a man whose on-court career peaked at number 14 in the world and whose real fortune was built entirely away from a tennis court.
Here is the full breakdown of the five richest tennis players in the world right now.
5. Serena Williams: $350 Million Plus
Serena Williams remains the wealthiest female tennis player in history and it is not particularly close. She earned $94.8 million from prize money alone during her playing career, a figure no other woman in the sport has come near, and then layered on top of that a series of endorsement deals with Nike, Wilson, Audemars Piguet, Gucci and Disney that kept her name commercially relevant long after retirement.
What has genuinely accelerated her wealth in recent years is Serena Ventures, her venture capital firm that has invested in over 60 startups and positioned her as one of the most credible and successful athlete-turned-investor stories in modern sport.
4. Rafael Nadal: $400 Million Plus
Several publications have Nadal's net worth listed at around $220 million but that figure appears significantly undervalued when set against Spanish financial reporting.
The list by El Mundo ranking the wealthiest people in Spain had him ranked at around €345 million, equivalent to $407 million today, based on his total winnings in his career estimated at $134.9 million, combined with his lifetime association with Nike and Kia.
His global network of Rafa Nadal Academies has also grown into a genuinely significant business operation, with locations across multiple continents establishing them as premier training destinations rather than simply vanity projects.
3. Novak Djokovic: $500 Million Plus
The challenge with calculating Djokovic's net worth is that some publications place him at $240 million, a figure that is almost impossible to reconcile with the fact that he has earned $192.7 million from prize money alone, making him the all-time leader in on-court earnings by a considerable margin.
Forbes estimated his total wealth at $510 million back in 2023, with more than $300 million of that coming from off-court sources including his long-term deals with Lacoste and Hublot, his Novak Cafe and Restaurant chain and various wellness investments. That figure has almost certainly grown since then.

2. Roger Federer: $1.1 Billion
In August 2025 Forbes confirmed what many had suspected was coming, Federer is a billionaire, with a net worth of $1.1 billion.
He earned $131 million from prize money during his playing career which is a staggering amount on its own, but the real engine of his wealth is a $300 million deal with Uniqlo combined with a significant minority stake in Swiss shoe and apparel brand On Running, whose value exploded following the company's IPO.
Federer was an early backer of On and has watched that investment transform into the cornerstone of a genuine business empire. He is only the second player from the professional tennis world to reach billionaire status, which brings us to the man at the top.
1. Ion Tiriac: $2.3 Billion
Almost nobody outside of tennis knows who Ion Tiriac is and almost nobody inside tennis is surprised that he is by far the wealthiest person to have ever played the sport professionally.
The Romanian, nicknamed the Brasov Bulldozer, peaked at number 14 in the world rankings and won the 1970 French Open doubles alongside compatriot Ilie Nastase, a perfectly respectable career but hardly the foundation you would expect for a $2.3 billion fortune.
That fortune was built entirely post-retirement through the Tiriac Group, which spans real estate, auto dealerships, financial services, insurance and retail across multiple European markets. He founded Tiriac Bank, the first private bank in post-communist Romania, and grew it into a business empire that Forbes now places at $2.3 billion, putting him at number 1,775 on the list of the richest people in the world as of February 2026.
He was the first person from the tennis world to cross the billion dollar mark. Federer is the second. The gap between them is still nearly $1.2 billion.
