Anthony Joshua is set to add even more millions into his bank account when he fights Andy Ruiz Jr. in their December 7 rematch in Saudi Arabia.
But the deposed WBA, WBO and IBF heavyweight champ is still well behind boxing legend Floyd Mayweather when it comes to overall net worth.
Mayweather is believed to be worth around £435m - a whopping £392m more than Britain's Olympic gold medal-winning hero.
But spare a thought for the man who used to terrorise boxing - Mike Tyson.
Once believed to be worth £233m, film star and cannabis farmer Tyson is down to his last £3m. He filed for bankruptcy in 2003 after building up huge debts.
