Eddie Hearn was careful not to attach actual numbers when asked how much money Anthony Joshua and Tyson Fury will make for their heavyweight showdown.

Joshua’s promoter did predict that they’ll be compensated comparable to the highest-paid boxer in the history of the sport. Hearn stated during his weekly appearance Tuesday on “The Ak & Barak Show” that the British heavyweights will make “Mayweather money” for their heavyweight title unification fight either late in May or at some point in June.

Hearn mentioned Mayweather in response to a question from co-host Akin Reyes regarding whether Fury and Joshua would make $100 million apiece for their fight.

“I think, you know, a lot depends on the numbers around the fight, in terms of the revenue, you know, the site fees, the pay-per-view numbers, the international TV,” Hearn said during a show that streams Monday through Friday on DAZN and SiriusXM. “But, you know, it’s certainly I think, you know, the biggest fight, the most lucrative fight, in boxing right now – unquestionably.

“That’s Mayweather money. You know? And we haven’t seen Mayweather money since Mayweather. So, no fighter’s earned anywhere near that kind of money since and, you know, this is the first time that, you know, fighters will be earning that kind of category of dollars. So, you know, I think it’s impossible to give a number. There’s no set purses for this fight because, obviously, it’s a revenue share. But it’s certainly gonna break records everywhere.”

Floyd Mayweather made more than $200 million from his victory over Manny Pacquiao in May 2015, an event that generated more than $600 million in overall revenue. He made nine figures for his technical knockout of UFC superstar Conor McGregor in August 2017 as well, but less than he earned for facing Pacquiao.

Joshua (24-1, 22 KOs), the IBF/IBO/WBA/WBO champ, or Fury (30-0-1, 21 KOs), the WBC champ, probably won’t earn from their fight as much as Mayweather made for his fights with Pacquiao or McGregor. Nevertheless, they already have come to an agreement for what figures to be the biggest fight of 2021.

“The truth is is, yes, the terms are agreed,” Hearn said. “There’s still, you know, devil in the detail, couple of issues to iron out on the TV partners and, of course, where it’s gonna take place. But ultimately, the terms of the fight have been agreed. Both guys are training at the moment, you know, with the understanding that this will be the next fight for them. So, whilst we can’t say the fight is signed, we can say that we’re closing in and it looks like both fighters are happy with the terms. Now we’ve gotta do I guess the real tough part – which is, you know, making sure that it’s papered, it’s signed, and we can move forward and see where this huge fight’s gonna take place.”

Hearn identified sites in “seven or eight countries” as possibilities, though it seems highly unlikely that the Joshua-Fury fight will be staged in the United Kingdom, due in large part to COVID-19 restrictions on fan attendance. Investors from “many countries in the Middle East,” eastern European countries, Australia, Singapore and the United States have expressed interest thus far, according to Hearn.

“It’s gonna cost someone a lot of money,” Hearn said. “But it is gonna be one of the biggest fights of all time, so there’s a lot of interest in this fight.”
