Jake Paul Says He'll Fight Soulja Boy For $20 Million

Jake Paul wants to fight Soulja Boy for $20 MILLION ... and he's telling TMZ Sports that he'll cough up his own 20 milli to make it happen!!!

ICYMI -- the social media superstar and rapper traded jabs in an Instagram Live session last week ... with Soulja offering Paul a HUGE chunk of cash to get him to square up in the ring.

Paul tells us this was no publicity stunt -- he really wants a piece of Pretty Boy Swag ... and as for the money, he'll have no problem putting up the $20 milli if Soulja can't swing it.

FYI -- you're sitting down, right? -- Paul can put his money where his mouth is. The dude reportedly made $21.5 million in 2018 alone, according to Forbes.

Of course, Jake knows his way around the ring ... he easily handled Deji in his first YouTube super fight and called out Chris Brown right after taking him down.

Clearly, Jake will happily settle for Soulja Boy.
