Bob Arum, CEO of boxing promotion company Top Rank, said the upcoming fight between Deontay Wilder and Tyson Fury could be the highest-grossing heavyweight title fight of all-time.
The highest-grossing pay-per-view heavyweight fight ever was Mike Tyson vs. Lennox Lewis in 2002, which grossed roughly $110 million.
The other pay-per-view heavyweight fight to gross close to that amount is the second Tyson vs. Evander Holyfield bout in 1997, which grossed approximately $100 million, according to Business Insider.
Floyd Mayweather Jr.'s defeat of then-UFC lightweight champion Conor McGregor in 2017 was the highest-grossing boxing fight of all-time, generating roughly $500 million in pay-per-view sales.
In a recent interview with ESPN, Porter took issue with Arum, who admitted he didn't give Porter "much of a chance," in his previous fight.
