Due to her pregnancy in January 2017, 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 $18.1 million in endorsements, Williams 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.
In addition to over a dozen sponsors including Nike, Intel, Audemars Piguet, JPMorgan Chase, Lincoln, Gatorade and Beats, Williams also launched her first solo fashion compilation, Serena, in May.
Williams is currently gearing up to match Margaret Court’s 24 grand slam title record at this year’s US Open.
