Canelo Alvarez and Amir Khan could be in for the biggest paydays of their careers when they meet at T-Mobile Arena on Saturday night. Reports indicate that the two middleweights will make eight figures for the bout, adding to their already lofty career earnings.

Headlining his first pay-per-view in the United States, Khan will be paid $13 million for the fight, according to British tabloid the Daily Star. Alvarez’s purse has not been revealed, but he’s likely to make than Khan when factoring in PPV revenue. Alvarez is the biggest draw in boxing now that Floyd Mayweather and Manny Pacquiao claim they’ve retired, and his fight against Miguel Cotto on Nov. 21 generated 900,000 PPV buys.

Much of the talk surrounding the fight is the leap that Khan is making in weight classes. After fighting at a career high 147 pounds just three times, the Brit is moving up to 155 pounds for Saturday’s bout. It’s not hard to see why Khan is making the move, considering he’s getting more money for a title fight than any British boxer has in the last five years.

Celebrity Net Worth lists Khan’s net worth at $30 million heading into the championship fight, though the number is unconfirmed and carries many variables. Five of Khan’s last six fights have been in the U.S., and he hasn’t been awarded a purse of more than $1.5 million for any of those bouts. But Khan makes more money from U.K. television deals and sponsorships, making him one of the wealthiest active boxers.

The website lists Alvarez’s net worth just below Khan’s at $27 million. Forbes reported that Alvarez made a career-high $12 million for his fight against Mayweather in September 2013. Khan’s purses totaled $2.75 million in 2014 and he made at least $3.5 million for his fight against James Kirkland on HBO on May 9 of last year. Alvarez was guaranteed $5 million against Cotto, but he made plenty more from PPV revenue and his Mexican TV deal.

Aside from the May 5 mega-fight a year ago, Mayweather was earning consistent purses of at least $30 million, and Pacquiao was often paid at least $20 million for his most recent fights. The winner of Saturday’s fight could set himself up for an even bigger payday, potentially against Gennady "GGG" Golovkin or even Pacquiao.
