In what Mayweather insists is "just another easy payday" for him, he will go toe-to-toe with Paul over eight rounds of boxing at the Hard Rock Stadium this weekend.
And with the fight just one day away, Mayweather claims to have already made $30m without even throwing a single punch - and that sum could rise to an eye-watering $100m in total.
"I'm fighting a YouTuber who thinks he's a real fighter and I'm getting crazy money for it - I've already made $30m just building up to this fight," Mayweather bragged to reporters at Versace Mansion in Miami Beach.
"This is not a real fight for me, it's a real fight for him.
"I retired from boxing, but I didn't retire from entertainment and I didn't retire from making money."
Mayweather, a former world champion across five divisions, retired from boxing with an unblemished record of 50-0.
Meanwhile, his social media opponent Paul has fought once and lost, to fellow YouTuber KSI.
He said: "It's not an exhibition - what exhibition is eight three-minute rounds?
"You know, this is a fight. If Floyd didn't want to rip my head off before my brother took his hat, now he's trying to kill me.
"He's trying to make an example of the big brother so the younger brother has to suffer, watch and witness.
"I don't know if you've seen Scarface, but that's what he's trying to do."
