Jake Paul believes it is 'very possible' he earns $1 billion from boxing - which would make him the richest fighter ever ahead of Floyd Mayweather.
Mayweather's last professional fight came in 2017 against Conor McGregor and he claims it made him a billionaire.
He earned the nickname 'Money' throughout his career and is regarded as one of the wealthiest men in sport.

YouTube star Paul is currently 3-0 and his last fight, a first-round knockout of ex-UFC star Ben Askren, sold 1.5 million PPVs in April.
In an interview with SunSport, the 24-year-old has claimed he can 'easily' become boxing's true PPV king by the time he retires.
Paul boasted: "I do think I can hit the $1billion prizefighter mark, easily.
"All I've got to do is keep on winning - and I will keep on winning - and we'll see.

"I think it's very possible and that's why I say there is no limit to where this can go. I have the ace up my sleeve. The ace up my sleeve is that I can actually fight."
Paul has been on a rampage in recent months in an attempt to seal 'more qualified' competition.
Prior to Askren, his two victories came against former NBA point guard Nate Robinson and fellow YouTuber AnEsonGib.
McGregor and Mayweather himself seem to be targets, with the latter having his hat stolen by Paul at a press conference promoting his fight with brother Logan next month.

Paul continued: "It's like, how long do I want to dedicate myself to these long, hard training camps? I see it happening for the next five, six years.
"But I want to have a family eventually. At the end of the day I'm an entrepreneur, so I can make money any way I want.
"It's not like boxing is my only outlet. I'm doing it because I love it and I'm having fun.

"It would be nice to hit 10-0 and retire but we'll see. This is just the start of my journey, not even the sky, there are no limits to this.
"I'm just enjoying each moment, each fight and taking it as I go."
'The Problem Child' has recently been offered a chance at world titles.
Promoter Kalle Sauerland, who heads Wasserman Boxing, took to social media to offer Paul a championship clash against IBF world cruiserweight champion Mairis Briedis.

He tweeted a video of Briedis taunting him, accompanied with the caption: "Hey @jakepaul - happy to arrange you taking a shot at Mairis Briedis belts, only condition if you lose you have to leave boxing...deal?"
