Coco Gauff strode into this year's US Open with a net worth matching her enormous status in tennis. The 21-year-old was in the headlines in the build-up to the Grand Slam after deciding to part with coach Matt Daly, days before the start of the action in New York.

It didn't stop her from reaching the second round as she battled past Australian star Ajla Tomljanovic 6-4, 6-7 (2-7), 7-5 in her first match. Despite her recent difficulties, particularly with her serving, she is scoring nothing but aces away from the court. Forbes understands she has pocketed a handsome £27.7million over the last 12 months. This includes £9m in prize money - £2.16m of which was for winning the French Open - and another £18.6m in sponsorship deals. This has led to her becoming one of the richest tennis stars on the planet.

According to Celebrity Net Worth, her value stands at a huge £26m. In the same way she is hungry for more Grand Slams, she is looking to increase her wealth by diversifying her investments. This past January, she strengthened her already impressive commercial portfolio by investing funds into Unrivaled, a three-on-three women's basketball league established by Breanna Stewart and Napheesa Collier during the summer of 2023.

When the investment was made, she posted on X: "My dad always wanted me to follow in his footsteps and play basketball. Sorry dad but this is as close as it will get."

Three months later, Gauff announced she would also be parting ways with her agency, Team8, and launching her own management company with WME called Coco Gauff Enterprises. She said the new venture "reflects my passion for making an impact - not just in tennis, but in business, philanthropy and beyond."

In an official statement, she said: "From the moment I first picked up a tennis racket, I've always believed my purpose extended far beyond the court. I'm excited to build something that allows me to take greater ownership of my career while also creating opportunities that extend beyond myself as I continue to grow as an athlete, entrepreneur and changemaker.

"This is just the beginning of an exciting new era for me, and there is much more to come, which I'll be excited to share in due time. As always, tennis will continue to be my main priority!"

Gauff's battling victory over Tomljanovic would have been a huge relief after being knocked out in the first round of Wimbledon by Dayana Yastremska. It was a huge setback after winning the French Open.

Her main focus in recent weeks has been her serve, after hitting 311 double faults in 2025, more than anybody else on the WTA Tour. She opened up about her changes, including a huge adjustment to her technique, saying: "I needed to make a change, technical change to it, and I don't want to waste time continuing doing the wrong things."
