Naomi Osaka and Coco Gauff are two of the biggest names in women’s tennis, but their financial journeys have played out at different speeds, with Osaka having been in the global spotlight for longer, turning her success into a big commercial empire that includes endorsements, media and business ventures. Gauff, in the meantime, has rocketed to the top of the list of the game’s most marketable young athletes.The analogy has taken on new meaning in the 2026 US Open, with both players still big draws on and off the court. Gauff, the No. 4 seed, had a nice run of wins in the tournament. Osaka also breezed through the early rounds.
Naomi Osaka and Coco Gauff net worth comparison in 2026
The full private finances of neither player are public, but Coco Gauff’s net worth is less than Naomi Osaka’s. Osaka’s wealth has been boosted by years of top-tier endorsement deals and business ventures, while Gauff’s earnings have accelerated as her Grand Slam success and global profile have grown.According to Celebrity Net Worth, Forbes projected Gauff’s 2025 earnings to be around $33 million, with roughly $25 million from endorsements and $8 million from prize money. As of August 28, 2026, Forbes also estimates her earnings for 2026 at $35.5 million.
| Financial category | Naomi Osaka | Coco Gauff |
| Estimated net worth | About $45M–$60M | About $35M+ |
| Career prize money | $25M+ | $31.8M+ as of May 2026 |
| Major income source | Endorsements and businesses | Endorsements and tennis |
| Key sportswear partner | Nike | New Balance |
| Business interests | Evolve, Hana Kuma, KINLÒ | Coco Gauff Enterprises |
| Estimated annual income | About $55M | About $33M |
Celebrity Net Worth had Gauff’s career prize money at $31.83 million through May 4, 2026, which would have made her 11th on the WTA’s official career prize-money list at the time.
Naomi Osaka’s wealth extends beyond tennis
Osaka’s financial profile has expanded far beyond tournament earnings. The four-time Grand Slam champion has built significant commercial value through partnerships with brands like Nike, Louis Vuitton, Mastercard and other international companies, and her appeal has also bled into fashion and entertainment, with her 2026 US Open appearances once more emphasising her status as a sports and fashion crossover figure.That income has been further diversified by her business interests. Osaka co-founded Evolve, a sports management agency, and has been involved with Hana Kuma, a media company. She also created KINLÒ, a skincare line focused on inclusive sun protection.That broader commercial strategy is one reason Osaka’s wealth cannot be measured solely through WTA prize money. Her tennis earnings are just part of a larger financial portfolio built on sponsorships, intellectual property, entrepreneurship and cultural influence.
Coco Gauff builds a powerful commercial portfolio
Gauff’s financial trajectory has been a little different, as her earnings have increased with her rapid ascent in the pro tennis world. Her first Grand Slam singles title came at the 2023 US Open, and she followed that up with another at Roland-Garros in 2025. She also won the French Open doubles title and has more than $30 million in career prize money.So the financial comparison is in favour of Osaka in estimated accumulated wealth, while Gauff is rapidly closing the commercial gap through prize money, major sponsorships and an increasingly independent business strategy. The record $108 million prize pool for players at the 2026 US Open is another sign of tennis’ increasing financial size.
