Jake Paul makes massive bet on his fight with Mike Tyson that could cost him millions

Jake Paul has bet on his own fight, but it could end up costing him millions if he loses.

The 'Problem Child', 27, will take on Tyson, 58, tonight (November 15) at the AT&T Stadium in Arlington, Texas.

It's been a long time coming after the fight, originally announced in March and planned for July, was postponed following Tyson's health emergency.

The match will see the heavyweight champion take on his first pro opponent since 2005, when he was defeated by Kevin McBride and announced his retirement.

As the final countdown to the match commences, fans are taking to social media to predict who will be victorious.

While one 3D simulation predicted a grizzly defeated for Paul, a video of the boxers' training regimes has also gone viral after it compared Iron Mike's training to that of the YouTuber.

There's already been plenty of drama between the pair, including rule changes, alleged 'leaked' scripts and Tyson even slapping Paul at the weigh-in.

Now, Paul has promised to bet a huge amount on himself winning the fight, revealing he'll put his entire $40 million purse on the line.

When boxer Katie Taylor was asked to predict who would win the fight - and settled on Tyson - Paul challenged her with a wager.

“How much do you want to bet?” he asked.

“Do you want to bet your purse?” Taylor responded.

“Yeah, let’s bet the purse,” Paul said, after which the pair shook hands.

Paul had previously explained he was 'here to make $40 million and knock out a legend'.

Taylor is set to defend her light-welterweight record in a fight against Amanda Serrano tonight, prior to Paul's fight against Tyson.

Ahead of this evening, many have questioned why Tyson is returning to the ring after almost 20 years of retirement.

While he's set for a big payday, he insisted that money wasn't a contributing factor to his decision.

When asked by LADbible Group how much he believed he could make from the fight, Tyson said: "This fight is not going to change my life financially. If I did it for free, it’s not going to change my life financially. My wife is constantly telling me, you do not need to do this fight."

He went on to say of his reasoning for accepting the high profile fight: "This is what I want to do, this is me. I’m seeking my glory."
