Floyd is guaranteed $32 million, Dan Rafael of ESPN reports. Maidana will make $1.5 million, the biggest purse of his career, plus Argentine TV rights.
This is typical for Mayweather fights.
He made $41.5 million in the Canelo Alvarez fight in September, compared to $12 million for Alvarez.
Mayweather's manager explained the pay gap to ESPN:
"He's a terrific entertainer and he is the reason why this arena will be packed and why there will be a million-plus (buys on pay-per-view) - because it's all about the Mayweather experience."
Mayweather is the highest-paid athlete in the world. He gets paid twice a year - once when he fights in the spring, and once when he fights in the fall.
