Serena Williams is worth $400 million. She hasn’t played professional tennis in nearly four years.

That number, confirmed by Forbes in June 2026 as she announced her wildcard entry into Wimbledon, makes her the richest female athlete in the history of sport — comfortably ahead of Maria Sharapova, who retired in 2020 with an estimated $325 million in career earnings. And most of Serena’s fortune was built not on Grand Slam trophies but on endorsement deals, venture capital, and franchise ownership.

The Wimbledon comeback, then, is not about the money. Wimbledon’s winner’s check this year is £3.6 million — real money for most people, a rounding error for her.

Where Does Serena’s $400 Million Actually Come From?

The short answer: from everywhere.

Her career prize money totals $94.8 million — the highest ever for a female player. But that figure represents less than a quarter of her estimated $620 million in lifetime pre-tax earnings. The rest came from off-court income that has, in recent years, eclipsed anything she ever earned while competing.

In the past 12 months alone, Williams earned an estimated $50 million before taxes — more than in any single year as an active player. She now holds ten active sponsorship deals, four of which date back to her last time on tour: Audemars Piguet, Lincoln, Nike and Wilson Sporting Goods. More recent additions include Factor heat-and-eat meals, Heineken, Ro (the telehealth company behind a GLP-1 weight loss campaign she fronts), and Reckitt Catalyst. Speaking engagements alone command $1 million or more per appearance.

Then there is Serena Ventures. The firm, which began as her family office before raising a $111 million inaugural fund in 2022, has backed 16 unicorn companies, with an early-stage focus on founders who are women or people of color. Her husband, Reddit co-founder Alexis Ohanian, was an early investor in Ro — one of her current brand partners.

How Serena Built Her Fortune: A Timeline That Didn’t Stop in 2022

Williams turned pro in 1995 at age 14 and won her first Grand Slam in 1999. But the financial architecture of her career was always about much more than tennis.

In 2009, she quietly acquired a stake in the NFL’s Miami Dolphins. That franchise is now valued at $7.5 billion — a 640% increase since she joined the ownership group. In 2020, she co-led the founding investment in Angel City FC, the NWSL expansion side that has since become one of women’s soccer’s most valuable clubs. More recently, she and Ohanian purchased Los Angeles Golf Club, one of the six inaugural teams in the Tiger Woods and Rory McIlroy-backed TGL league, and she acquired minority stakes in both the Unrivaled three-on-three basketball league and the Toronto Tempo, a WNBA expansion franchise entering its first season.

When she announced her “evolution away from tennis” in a 2022 Vogue essay, Williams had already hauled in close to $450 million in lifetime earnings. The four years since have added another $170 million — without a single match point.

What’s Next for Serena Williams’ Net Worth in 2026?

The Wimbledon return was not primarily a financial calculation, but it was not without commercial logic either. Every week she is back on court expands her media footprint: she launched a podcast with Venus Williams, a children’s book is already out, and a memoir is reportedly forthcoming from Random House.

She lost her first-round singles match on July 1 against Maya Joint, a 20-year-old Australian ranked 53rd in the world, in three sets. She had been listed, improbably, with the 17th-best odds to win the entire tournament — a sign of how much the market values the Serena name even against four years of rust.

The current women’s number one, Aryna Sabalenka, has won barely half as much career prize money as Serena, even after passing Venus Williams on the all-time list in 2025. The gap between Serena and every other female athlete — financially speaking — remains enormous and is not closing.

Forbes’ $400 million figure, matched against Celebrity Net Worth’s estimate of approximately $350 million, places her wealth in a range that no woman in professional sports has come close to reaching. The discrepancy between sources reflects different methodologies for valuing private equity holdings — not any meaningful uncertainty about her status at the top of the table.

She may or may not play another professional match. Either way, the business keeps running.
