Coco Gauff is the highest-paid woman in sports, and her fortune keeps climbing. The American tennis star carries an estimated net worth of $35 million in 2026, built on Grand Slam prize money and one of the deepest endorsement portfolios in the game. The timing is no accident: Gauff began her French Open title defense this week at Roland Garros, the tournament that runs May 18 to June 7, 2026.

Forbes has ranked Gauff the highest-paid female athlete for two consecutive years, crediting her with roughly $33 million in total earnings over its 2025 measurement period. Only a small slice of that — about $8 million — came from playing tennis. The rest, some $25 million, came from off-court deals. For a 22-year-old, it is a rare financial profile, and it explains why she sits comfortably inside the wider conversation about the highest-paid athletes on the planet.

Where Does Coco Gauff’s Money Actually Come From?

Two engines drive Gauff’s wealth: the court and the contract.

On court, she has banked more than $24.3 million in career prize money, a total that places her among the top 20 earners in WTA history. Her most lucrative season was 2024, when she collected roughly $9.35 million — including a record $4.8 million payout for winning the WTA Finals, the largest single check in the history of women’s tennis. Grand Slam paydays add up fast, too; the sums on offer at a major are eye-watering, as our breakdown of Australian Open 2026 prize money shows.

Off court is where the real money lives. Gauff’s endorsement roster reads like a blue-chip index: a long-running apparel and footwear deal with New Balance, plus partnerships with Bose, Baker Tilly, Barilla, Beats by Dre, UPS and a smart-glasses tie-up linked to Ray-Ban and Meta. Sponsors pay a premium for an athlete who is young, marketable, American and already a two-time major champion — a combination few players, male or female, can offer.

How Coco Gauff Built Her Fortune

Gauff turned professional in 2018 and announced herself at Wimbledon in 2019, beating Venus Williams as a 15-year-old. The breakthrough title came at the 2023 US Open. The defining one arrived at the 2025 French Open, where she beat Aryna Sabalenka to become the first American woman to win in Paris since Serena Williams in 2015.

Each milestone reset her commercial value. Endorsement contracts were renegotiated upward, new sponsors signed on, and Gauff’s team built a portfolio designed to outlast her playing career. She has spoken openly about wanting a business life beyond tennis — a contrast with players who lean almost entirely on prize money. To see how unusual her earnings mix really is, it helps to compare it with what the top tennis players actually take home.

What’s Next for Coco Gauff’s Net Worth in 2026?

The next chapter is being written in Paris right now. Gauff arrived at Roland Garros after reaching the final in Rome, where she lost a tight three-setter to Elina Svitolina — the kind of result that signals form rather than fatigue. Players also collect serious money simply for going deep at a Masters-level event, as our ATP and WTA Rome 2026 prize money guide lays out.

A successful French Open defense would do two things at once: add a multi-million-dollar winner’s check and, more importantly, trigger another round of endorsement escalators. At 22, with two majors already secured and her commercial value still climbing, Gauff’s $35 million is best read as a floor, not a ceiling.

How high do you think Coco Gauff’s net worth will climb by the end of the decade? It is a number worth watching.
