The 2017 US Open Tennis Championships are currently underway in New York City.

The fourth and final Grand Slam of the year is handing out a total of US$50.4 million, the largest sum of prize money in tennis history. The men’s and women’s singles champions will each receive a check for US$3.7 million.

That’s a nice payday in and of itself, but most of the high-ranking players are also locked into endorsements with top sports and luxury brands, banking multiple times their on-court earnings in any given year.

Below, we take a look at the 30 highest-paid tennis players of all time, based on on-the-court winnings. While the list is skewed towards recent players, it’s a mix of both men and women, as well as current players and all-time greats.

Data is from the ATP and WTA tours. Doubles and and mixed-doubles earnings are included in the career winnings, but are not included in the number of titles won.
