With the announcement that Mayweather vs. Pacquiao is finally going to happen, many thought about how much this fight will generate. Answer: A lot! It will shatter all boxing financial records. With the help of CBS and Showtime, Mayweather could earn up $120 million for 12 rounds, if that, of boxing, while Pacquiao will make around $80 million. Boxing depends so much on pay-per-view sales and will continue to do so, but this time it’ll be at a premium price come May 5. Only if Muhammad Ali or Mike Tyson were fighting today, they could probably beat Mayweather records. Here are boxing’s richest fights.

In probably the most talked-about boxing match ever, Mike Tyson racked in $30 million after biting part of the ear of opponent Evander Holyfield. It was the rematch after the Holyfield put a beating on Tyson for 11 rounds in the first bout. It was a huge upset, and as a result, Holyfield v. Tyson II became highly marketable. Tyson made $30 million, while Holyfield collected $33 million as the champion. In addition to 1.9 million pay-per-view buys, the fight made $100 million with tickets sales. Many fans felt ripped off as the fight ended in the third round when Tyson got a piece of Holyfield’s ear.

4. Lennox Lewis vs. Mike Tyson – June 8, 2002 – $112 million

If a heavyweight fight involved Mike Tyson, the bout would make a ridiculous amount of cash. In his final heavyweight fight, champion Lennox Lewis of the UK kept his title belt after knocking out Tyson in the eighth round after taking a heavy right hook. The fight had nearly 2 million pay-per-view buys and the Pyramid in Memphis (host) charged $2,400 per ticket, generating $112 million.

Mayweather vs. Saul Alvarez (the One) was the second of Mayweather’s six-fight deal, which generated $150 million.
