Serena Williams – $41.5M

Serena Williams is the second highest-earning female athlete in the world in 2021. She is no stranger to making millions in prize money and winning large bonuses and is also not an amateur as a brand ambassador. A former World Number One, Williams has won 23 “Grand Slam” singles titles throughout her career.

Now also a mother of one, Williams is worth $210 million. She continues to make over $40 million every year ($41.5 million in 2021), of which a fair share consists of money from sponsorships. Some of the brands she represents are “Nike,” “Gatorade,” and “Wilson.” Williams also has her very own holding company named “Serena Ventures.”
