ANTHONY JOSHUA and Tyson Fury are among boxing’s biggest earners thanks to their lucrative contracts.
Some of the sport’s top attractions have been given eye-watering guarantees when signing on the dotted line.
And these sums come BEFORE massive pay-per-view sales that would increase the fighters’ earnings even more.
Here SunSport takes a look at the biggest contracts in boxing history.
Canelo Alvarez – £278m
The Mexican star signed sport’s most lucrative deal ever in 2018, when he penned an 11-fight DAZN agreement worth £278m ($365) spanning over five years.
But just three bouts and two years into the contract and Alvarez requested it be terminated as he split with DAZN and Golden Boy Promotions.
He still banked around £64.6m as a result of beating Rocky Fielding, Daniel Jacobs and Sergey Kovalev.
Canelo, 30, is now set to control his own career and return as a box office fighter, opposed to DAZN’s streaming platform.
Floyd Mayweather – £150m
When Mayweather came out of prison in 2012, he signed an exclusive six-fight PPV deal with Showtime a year later worth £150m.
But the American legend ended up taking home £340m thanks to the box office success of his fights against Canelo and Manny Pacquiao.
Mayweather, 43, retired after beating Andre Berto in 2015, but returned in 2017 to face UFC star Conor McGregor in a lucrative crossover event.
It was not included in his initial contract, meaning the £300m he banked after stopping McGregor in ten rounds means he earned about £640m while boxing on Showtime.
Anthony Joshua – £100m
Joshua penned a new three-year contract with Matchroom Boxing in 2018, worth £100m, SunSport reported at the time.
Since then, Eddie Hearn’s Matchroom signed a £760m deal with DAZN, who broadcast AJ’s fights Stateside.
Joshua landed himself a career high payday last December, after pocketing £66m after outpointing Andy Ruiz Jr in their Saudi Arabia rematch.
The 31-year-old’s net worth is now estimated to be around £90m, according to Sportekz.
Mike Tyson – £90m
Promoter Don King claimed in 1990 that Tyson had a contract with Showtime that guaranteed him £90m ($120m).
His last fight on HBO was against Alex Stewart, before he had two wins against Donovan Ruddock as part of his fresh Showtime agreement.
But Tyson was jailed in 1992 after being convicted of rape and spent three years behind bars before returning to the ring in 1995.
Iron Mike, now 54, would re-sign with Showtime after his prison release, making around £215m more before retiring in 2005.
Tyson Fury – £90m
In early 2019, Fury made the shock decision to postpone his rematch with Deontay Wilder to instead sign a deal with Top Rank and ESPN.
The contract was widely reported to be worth £80m as the Gypsy King had two tune up fights in the US before facing Wilder again.
He emphatically stopped the Bronze Bomber in seven rounds in a PPV which sold over 1 million buys in America and the UK combined.
Fury, 32, has two fights left on his current contract.
