I hope when he changes his mind to fight free, a promoter will sign him right away, but the way he partying and spending his money like what Mayweather is doing he will need to keep it up, so he will eventually agree to fight Usyk, he just wants an upper hand in the negotiation, he knows that people are going to ask for a match up for the unification of the title and for the undisputed and greatest boxer of all time, so he wants to be in a good side of the bargain by telling right away what his price will be and giving it a deadline, he is a good businessman too and he knows his value.
He will definitely have the upper hand in negotiations, after all he will be the A-side in this fight with Usyk. I really don't know how he spend his money, but I'm hinting that at least he have some good investments as we alll know that sooner or later he will have to retire. And maybe he has financial advisors at his side.
Nevertheless, his asking money might be a boxing record for his prize fight, the guaranteed money alone, and then we still have the PPV numbers. Usyk is really an elite boxer no doubt about it, but I will still favor Fury.
