Tennis champ Serena Williams
Due to her pregnancy in January 2017, Serena Williams was off the court for the majority of the past year, leaving her with only $62,000 in winnings. Still, the 23-time Grand Slam champion collected twice as many off-court coins than any other female athlete.
Earning her $18.1 million in endorsements, she was able to top the list by over $5 million, with Australian Open winner Dane Caroline Wozniacki second in line.
Though Forbes did not include a woman in their ranking of the world’s top 100 highest earning athletes of 2018 after Williams’ earnings fell by approximately $10 million since the year prior, only 16 male athletes earned more than Williams in sponsorship money over the last 12 months.
