2018 The World's Highest-Paid Athletes Earnings — as of 6/5/18 $285 M
Money Mayweather ranks as the world's highest-paid athlete for the fourth time in seven years. It only took 36 minutes in the ring against Conor McGregor for Mayweather to earn $275 million (he added $10 million more outside the ring). The fight, pitting the biggest stars in boxing and UFC, generated 4.3 million pay-per-view buys and more than $550 million in total revenue from all sources. Mayweather earned three times as much as McGregor as the "A" side and his role as promoter, while McGregor was forced to share his cut with the UFC where he is under contract. The fight pushed Mayweather's career earnings to $1 billion, joining Michael Jordan and Tiger Woods as the only athletes to reach 10-figures in earnings. Mayweather padded his 2017 earnings with endorsement deals with Hublot and Tequila Avion ahead of the McGregor bout. Hublot released a limited edition of 100 watches, priced at $28,300, as well as 10 numbered editions of the Mayweather timepiece set entirely in yellow gold and adorned with more than 400 diamonds. The numbered edition cost $93,700 and both watches came with a boxing glove signed by Mayweather.
