Mayweather's fortune was built on 12 straight blockbuster payouts of at least $25 million since he became the biggest pay-per-view star in the sport after his 2007 split decision win over Oscar De La Hoya. That fight generated 2.5 million PPV buys, the most in the history of the sport to that point.
Money Mayweather’s earnings got an added boost through his creation of Mayweather Promotions in 2007. The move allowed Mayweather to cut out the middleman and keep both the boxing and promotion fees for his fights. Mayweather had an opt-out clause in his contract with Top Rank that let him out of his promotion deal with the company for $750,000. He exercised the option in 2006. “Floyd walked into Top Rank’s office, handed them a check and the rest is history,” Leonard Ellerbe, CEO of Mayweather Promotions, told Forbes last year.
His biggest payday came in May 2015 for his bout against Manny Pacquiao, which was six years in the making. The much-hyped fight largely disappointed the paying audience, but it set multiple boxing records, including PPV buys (4.6 million), total gate ($73 million) and sponsorships ($13 million). The fight grossed more than $600 million and was the highest-grossing, single-day sporting event ever.Mayweather's take: $240 million.
Mayweather retired after defeating Andre Berto in September 2015. The fight pushed his career earnings to $700 million and his career mark in the ring to an unblemished 49-0, matching the all-time record of Rocky Marciano. Rumors of a Mayweather comeback continue to swirl. Mayweather fueled them in June when he trademarked TMT 50 and TBE 50, which stand for "The Money Team" and "The Best Ever.
Mayweather has spent tens of millions on luxury cars, including a $4.8 million Koenigsegg CCXR Trevita "hypercar" billed as the most expensive car in the world. Cars depreciate quickly, but Mayweather has built a vast real estate portfolio with properties in Miami, New York, Los Angeles and Nevada.
