2. George Foreman, 75

Estimated net worth: US$300 million

Despite starting his successful boxing career back in the 1960s and fighting the likes of Muhammad Ali, George Foreman’s boxing fortune reportedly peaked at a mere US$5 million during his time in the ring at the time of his first retirement.

Instead, Foreman made the bulk of his millions from a very clever and fortunate business investment. In 1994, after adopting a healthier lifestyle, Foreman became a spokesperson for Salton’s fat-reducing grill. By 2009, the George Foreman Grill had sold over 100 million units. Foreman has never confirmed how much he got paid from the endorsement, but in 1999 it was revealed Salton had paid him US$138 million. Foreman also once said that he made US$8 million a month from his share of profit for the grills.

1. Floyd Mayweather, 47

Estimated net worth: US$400 million

While he might be professionally retired, Mayweather doesn’t mind fighting for a big cheque from time to time. In November 2022, he famously earned around US$30 million to battle against social media personality Deji Olatunji during an exhibition match in Dubai, per British media. It’s no wonder Mayweather is among the highest-paid athletes of all time, and one of just six athletes ever whose career earnings have topped US$1 billion, per Forbes.
