Anthony Joshua will sign a new three-year deal worth £100 million with Matchroom, Eddie Hearn's promotion company.
Matchroom have just signed a staggering $1bn deal with sports streaming company DAZN, whose budget for boxing is bigger than American giants HBO and Showtime combined.
Hearn, 69, said, “Anthony is an astute young man and he knows what Matchroom has to offer him when his contract runs out in November.
“To start with, Anthony is signed to the biggest and best promotional company in the world. We have the financial clout to make sure the big fights can go ahead at the big venues.
“We also have an exclusive contract with Sky Sports to screen quality boxing. There is also Sky Box Office.
“On top of all that, Anthony is also a friend.
“If he went, it would be like someone in the family leaving.
“No one at Matchroom is putting Anthony under pressure — but I am as confident as anyone can be in boxing.”
Meanwhile, Anthony Joshua has been ranked fifth richest young sports star in Britain. The 28-year-old is now worth £35 million after earning a whooping £18 million when he defeated James Parker in their heavyweight fight in March.
Hearn, has boasted that Joshua will become the first billionaire boxer.
“His commercial potential outside the ring is huge, way beyond Beckham and the world’s top footballers,” he said.
“He has a much bigger cross-over in terms of potential.” Joshua is forecast to rise up the rankings next year.
Golfer Rory McIlroy, 29, tops the list with £110 million, Andy Murray second with £83 million, Gareth Bale is third with £74 million and Manchester City's Sergio Aguero fourth with £48 million.
