But the money he got from endorsements is just peanut though as compare to fighting Manny which is going to be the biggest fight ever again. He goes out prior to the announcing of the winner in the Pacquiao-Thurman, because he knows for sure that he will be called out by Manny, hehehehe. He will be tempted to come back and fight Manny one last time -- if the price is right. 
Take a look at the recent Instagram post of Floyd Mayweather and check if there's a hint of a rematch in the next coming months or perhaps years
"I find it real ironic how every time Pacquiao's name is brought up in the media, my name is always attached to it. This man's entire legacy and career has been built off its association with my name and it's about time you all stop using my brand for clout chasing and clickbait and let that man's name hold weight of its own. For years, all you heard was that " Floyd is afraid of Manny Pacquiao". But what's funny is, when we finally fought, I won so easily that everyone had to eat their words! All of the so called boxing experts, critics and jealous American "fan base" either went mute and ran for cover or made every excuse in the world as to why I should give Manny Pacquiao a rematch. My take on all this bullshit is that yall are just upset that I broke Rocky Marciano's record and hate the fact that a Black, high school dropout outsmarted you all by beating all odds and retiring undefeated while maintaining all my faculties simply by making smart choices and even smarter investments. Ultimately, I will always have the last laugh!"
He is making money without breaking a sweat. He will not give up that record because if he did, his market value will go down and Senator Manny's market value will skyrocket.
I've watched this in the news, on it is right that on the statement of Floyd Mayweather it is cleared that there will be no more rematch
will be happen, unless Floyd needs a million dollars to earn, probably He will suddenly change his mind to have a rematch to Senator
Manny Paquiao, but as of the moment no sign for that.
