According to Forbes, Mayweather’s career earnings before fight with UFC champ Conor McGregor totaled approximately $700 million. Some insiders are estimating that Mayweather will earn over $300 million for his 10-round TKO of McGregor.
That would launch Mayweather over $1 billion for career earnings, a mark reached only by two other elite, iconic athletes: Michael Jordan and Tiger Woods. Each has earned about $1.5 billion over the course of their careers from sponsorships, winnings, salaries, and the like.
