Serena Williams and the $400 Million Gap in Women's Sports
Serena Jameka Williams hasn’t played a full season in years. She hasn’t needed to. Her legacy now sits on a balance sheet as comfortably as it once did on a scoreboard.
With an estimated net worth of $400 million, Serena stands alone. No active woman in sport is close. No retired one either. The richest female athlete of all time has turned a generational tennis career into an empire that keeps expanding long after the last handshake at the net.
At the other end of the scale, the current queen of annual earnings, Coco Gauff, is raking in around $33 million a year. Huge numbers for a 21‑year‑old. Yet in wealth terms, she is still chasing a distant silhouette: Serena’s $400 million is not just a record, it’s a chasm.
This is the financial landscape of women’s sport at the very top.
The $400m standard: Serena’s empire
Serena Williams’ numbers barely look real.
Forbes pegs her net worth at roughly $400 million as of June 2026, the highest ever for a woman whose fortune is rooted primarily in sport. On court, she banked $94.8 million in prize money — more than any woman in WTA history — built on 858 singles wins, 73 titles and 23 Grand Slam singles crowns. Seven Australian Opens. Three French Opens. Seven Wimbledon titles. Six US Opens. The most dominant résumé of the Open Era.
The money didn’t stop when the trophies did. Over the last 12 months alone, Serena is estimated to have brought in another $50 million before taxes and fees. Ten long-term sponsorships — including Audemars Piguet, Lincoln, Nike and Wilson — keep the cash flowing years after retirement in 2022.
Then there is Serena Ventures. As CEO, she has raised $111 million for a first fund, backing 16 companies and taking minority stakes in the Miami Dolphins, Angel City FC and the WNBA’s Toronto Tempo. The portfolio stretches from venture capital to real estate, from Florida to Paris.
She changed the sport. Now she’s changing the balance sheets.
The chasing pack: Sharapova and Venus
Behind Serena, there is daylight. Then Maria Sharapova.
The Russian, who retired in 2020, sits on an estimated net worth of $175 million. For more than a decade she was the world’s highest‑paid female athlete, pulling in roughly $300 million in combined prize money and endorsements over her career. A five‑time Grand Slam champion who completed the career Grand Slam, she fronted Nike, Porsche, Head, TAG Heuer and Evian all at once during her commercial peak.
Sharapova didn’t stop at being a brand ambassador. In 2012 she launched Sugarpova, her own candy line, adding an extra revenue stream that outlived her time on tour. When she finally walked away from the sport, the money was already stacked. She is the clear No. 2 on this list, but still more than $200 million shy of Serena.
Then comes Venus Williams at about $95 million.
Venus’ prize money alone — $42.8 million — ranks fourth all‑time on the WTA. A seven‑time Grand Slam singles champion and five‑time Wimbledon winner, she was also a driving force in the battle for equal prize money at the majors, a fight that reshaped the economics of women’s tennis.
Off the court, she built her own lanes. Fashion label EleVen and interior design firm VStarr Interiors expanded her portfolio, while a joint podcast with Serena, Stockton Street*, launched in 2025, added another media arm to the family business.
The Williams sisters didn’t just dominate the sport. They rewrote what a female tennis star could be worth.
Danica Patrick and the non‑tennis outlier
Step away from the baseline and one name stands out: Danica Patrick.
With an estimated net worth of $80 million, Patrick is the richest woman on this list whose primary sport was not tennis. The only female driver ever to win an IndyCar race — the 2008 Indy Japan 300 — she turned that breakthrough into one of the most recognisable brands in American motorsport.
Her peak years saw her earn more than $10 million annually, powered less by prize money and more by long‑running commercial partnerships. GoDaddy, Coca‑Cola and Peak antifreeze put her on billboards and in Super Bowl ads, lifting her earnings into a tier rarely seen by women in racing.
Patrick retired from competition in 2018, but she hasn’t parked her ambitions. In early 2025, she invested in Unrivaled, the women’s basketball league, adding another layer to a growing post‑racing portfolio.
Osaka, Sörenstam, Biles and the new business of being a star
Naomi Osaka sits at roughly $45 million in estimated net worth — a figure that looks almost conservative when stacked against her earning power.
Between 2019 and 2025, Osaka pulled in around $230 million, with only about $25 million of that coming from prize money. The rest came from a commercial machine: she co‑founded sports agency Evolve, launched KINLÒ skincare and created production company Hana Kuma. She topped Forbes’ highest‑paid female athlete list three years running, peaking at $51.1 million in 2022 and setting a personal best of $57.3 million in 2021 alone.
Annika Sörenstam, with around $40 million to her name, did something similar in golf long before this current generation. The Swede won 72 LPGA Tour titles, including 10 majors, and dominated her era so thoroughly that her name still defines excellence in the women’s game.
She retired from full‑time competition in 2008, then went to work on the business side. Golf course design, her own wine label, the Annika Foundation — all of it built on the credibility of a once‑in‑a‑generation career. Rolex and Callaway stayed with her long after she stepped away, and she even returned to competitive play at the 2022 US Women’s Open.
Simone Biles, estimated at $30 million, represents a different kind of power.
The most decorated gymnast of all time, Biles turned a sport that rarely produces mega‑earners into a platform for major deals. She endorses Audemars Piguet, Lilly, Nulo Pet Food, K18 haircare and gymnastics brands GK Elite and Spieth America. The Netflix documentary Simone Biles Rising drew Emmy recognition, but it was her decision to withdraw from several events at the Tokyo 2020 Olympics — to protect her mental health — that made her one of the defining athletes of the decade. Far from harming her marketability, it deepened it.
The message is clear: performance opens the door; personality and principles decide how wide it stays.
Gauff, Vonn, Rousey: the modern money makers
Coco Gauff is the youngest name on the list and the one rising fastest.
At just 21, she already has an estimated net worth of $28 million. In 2025, she topped Forbes’ highest‑paid female athletes list with $33 million in annual earnings, ahead of Aryna Sabalenka ($30 million) and Iga Swiatek ($25.1 million). Around $8 million of that came from prize money — boosted by a French Open title — with another $25 million arriving via endorsements with New Balance, Bose and Baker Tilly.
Her net worth still trails those yearly figures, but that is a timing issue, not a ceiling. If the trajectory holds, Gauff is the one with a real shot at chasing down the giants ahead of her.
She currently shares the $28 million bracket with Lindsey Vonn, the most decorated American alpine skier in history. Vonn’s four overall World Cup titles and 2010 Olympic gold in Vancouver gave her a platform; Red Bull, Under Armour and Rolex turned it into a fortune.
Vonn retired in 2019, yet she remains a fixture in commercial campaigns and media projects. The mountain career ended. The brand didn’t.
Ronda Rousey rounds out the top 10 at around $25 million.
The first woman to headline a UFC pay‑per‑view and the first female inductee into the UFC Hall of Fame (2018), Rousey’s peak between 2014 and 2016 made her one of the most recognisable athletes on the planet. She crossed from MMA into WWE and Hollywood, picking up endorsement deals with Reebok and Monster Energy along the way. In 2024, she released her memoir, Our Fight: A Memoir, adding another chapter — and another revenue stream — to a career built on shock finishes and crossover appeal.
The numbers behind the names
Strip the list down to raw figures and a pattern jumps out.
From Serena at $400 million to Rousey at $25 million, the top 10 spans a net worth range of $375 million. The vast majority of that money did not come from prize money or salaries. For the top‑earning women, around 70% of income comes from endorsements, compared with roughly 35% for the highest‑earning men.
Only five women in sports history have ever cleared $30 million in a single year: Naomi Osaka, Serena Williams, Coco Gauff, Maria Sharapova and Aryna Sabalenka. Tennis dominates that group, just as it dominates this list.
The current rankings by estimated net worth:
- Serena Williams (Tennis) – $400M
- Maria Sharapova (Tennis) – $175M
- Venus Williams (Tennis) – $95M
- Danica Patrick (Motor Racing) – $80M
- Naomi Osaka (Tennis) – $45M
- Annika Sörenstam (Golf) – $40M
- Simone Biles (Gymnastics) – $30M
- Coco Gauff (Tennis) – $28M
- Lindsey Vonn (Alpine Skiing) – $28M
- Ronda Rousey (MMA / Wrestling) – $25M
Behind these headline figures sits a broader surge. In 2025, a record 15 female pros earned more than $10 million in a single year through salaries, prize money and endorsements — up from just six in 2023. The money is climbing. The pool is widening.
The Serena question
One question hangs over all of this.
Will anyone catch Serena Williams?
Coco Gauff has the time and the momentum. Naomi Osaka, if she returns to full force on court, has the commercial engine. Maria Sharapova’s blueprint shows how long‑term endorsements and smart business moves can stretch a career’s value well into retirement.
Yet Serena’s $400 million mark is more than a number. It is a symbol of an era when one athlete bent an entire sport — and then an entire marketplace — around her.
As women’s football, basketball and other global sports sign record‑breaking deals and new stars emerge, the gap may finally start to close. But for now, the richest woman in sporting history remains the one who turned a tennis racket into a generational fortune — and left everyone else, quite literally, playing catch‑up.
