Jake Paul wants HALF of KSI’s stake in drinks company Prime if he wins Wembley winner-takes-all showdown next year

JAKE PAUL wants HALF of KSI's stake in drinks company Prime if he wins their winner-takes-all fight next year.

The pair of YouTube boxing rivals have agreed to a Wembley showdown next year, with their purses to be on the line.

But Paul has now upped the ante by calling to put their two business companies at stake.

KSI - nicknamed JJ - launched energy drink Prime with Paul's brother and former boxing opponent Logan this year.

Meanwhile his American rival recently revealed his new instant sports betting app Betr.

Paul said on his  "This is an exclusive. JJ, I'm proposing to you that when we fight, if I win I take half of your Prime equity. 

"Winner takes all and I get half of your Prime equity, but if you beat me you get half of my Betr equity."

KSI, 29, beat Logan, 27, in their 2019 rematch following a draw the year beforehand.

But they have formed a friendship in recent years before releasing Prime in January.

KSI returned to the ring after three years out to beat rapper Swarmz, 25, and so-called professional boxer Luis Alcaraz Pineda, 23, on the SAME NIGHT.

Paul, 25, meanwhile is set to face UFC legend Anderson Silva, 47, in his comeback fight on October 29.

But he is still calling for a grudge match against KSI and is willing to cross enemy lines to do so.

He said: "KSI, I've always said it that you can be the A-Side for your ego.

"Obviously you have an ego issue, I don't give a f*** about being the A-Side.

"We all know who the real A-Side is - I just want to knock you the f*** out, I'll do it in your own country.

"I'll let you be the A-Side because it doesn't matter when it's all said and done and you're asleep on the f***ing canvas."
