SERENA WILLIAMS – $200 M
Serena Jameka Williams is one of the most popular tennis players to have ever graced the court. She and her sister, Venus Williams, both started tennis training at such a young age with their parents as their coaches. This is the biggest investment the siblings ever made, which eventually paid off as they kept going. The results of their training became apparent when Serena Williams played in her first professional tournament at the age of 14 in 1995. In 1997, Williams started as the 304th in the rankings but, by the end of the year, she made it all the way to the 99th.

She earns 15-20 million dollars a year from tennis endorsements such as Nike and Kraft Foods. Between June 2019 and June 2020, Serena made $35 million, about $20 million of that came from endorsements.
