Serena Williams is one of the greatest tennis players in history and one of the richest female athletes ever, with an estimated net worth of $300 million, according to Celebrity Net Worth.
A lot of this wealth comes from her record-breaking tennis career, big endorsement deals, business investments, and a few ventures outside the sport.
With Serena making a surprise return to singles competition at Wimbledon 2026, her name is once again back in the spotlight.
Alongside her success on the court, she continues to grow her business portfolio through Serena Ventures and several other investments.
During her career, Serena racked up 23 Grand Slam singles titles, the most by any player in the Open Era, and sat as the world No. 1 for 319 weeks.
She earned over $94 million in prize money, the highest total for a female tennis player, and made millions each year from sponsorships and endorsement deals.
Companies such as Nike worked with her again and again across her career, which helped her become one of the highest-paid athletes in the world.
After retiring from professional tennis, Serena launched her clothing brand, S by Serena, and invested in dozens of companies through Serena Ventures.
She also owns minority stakes in the UFC and the Miami Dolphins, which have helped her continue building wealth.
Just when many thought her playing days were over, Serena Williams surprised the tennis world by accepting a singles wildcard for Wimbledon 2026.
She will play singles at the tournament for the first time since retiring at the 2022 US Open and is also set to play doubles at Wimbledon alongside her sister, Venus Williams.
