Drake Places $400K Bet On Jake Paul to KO Tommy Fury, Would Profit $1 Mil!

Drake's picking sides in the Jake Paul - Tommy Fury feud, placing a bet on The Problem Child to knockout TNT ... and judging by the massive size of the wager, Drizzy's feelin' confident the 26-year-old YouTuber-turned-boxer will turn out Fury's lights.

Drake posted the Stake betting slip on social media Saturday night ... and he's risking $400,000. In order for the superstar rapper to cash out, Jake can't just win the fight, he must KO Tommy (in any round). If that scenario actually unfolds, Drake would receive $1.4 million ... which included his initial bet ($400k).

The payout's so large because statistically, it's a longshot ... the odds say there's a less than 30% chance the fight ends by Paul KO.

FYI, Jake's 6-0 ... and 4 of those fights have ended by KO. Tommy's also undefeated ... and obviously has never been stopped.

Drake's no stranger to making huge wagers. In fact, he bet $965k total on the Super Bowl ... and while he didn't hit on all his bets, he did pretty well. He's also bets heaps of money on UFC fights.

While the rappers riding with Jake, Tyson Fury is (obviously) siding with his brother. The heavyweight champion revealed earlier this week he put down over $100K on Tommy to win by stoppage.

"I've got 100 racks on it for an inside-the-distance stoppage, so if [Tommy] loses, then I'll lose 100 bags as well," Fury told iFL TV.

Jake and Tommy also made a bet during fight week (though, we'll see if it comes to fruition). If Jake wins the fight, he gets Tommy's money. If Fury wins, Jake double his money.

Bets aside, Paul and Fury flat-out hate each other ... and Sunday's fight is the culmination of years of trash talk. The men were supposed to scrap on two previous occasions, but Tommy pulled out -- once for injury, and the other over a travel issue.
