Jake Paul has invested in the UFC 's parent company, Endeavor, in an effort to increase fighter pay and provide them with long-term healthcare.
Endeavor went public last April which meant the UFC also followed suit, allowing people to invest in the company for the first time since its founding in 1993.
Following the UFC's $4b sale in 2016, Endeavor only owned 50.1% of the UFC but they have since taken full ownership of the promotion.
Endeavor stock began trading at $24 per share last April and currently sits at just under $30 per share today.
Paul's investment in the stock comes after he teased a "plan" to improve fighter pay in MMA, with the entire UFC 270 card last weekend making just £1.3million.
"I’ve invested in EDR (UFC) stock with my partner Geoffrey Woo to focus on UFCs ESG standards relating to fighters," he wrote on Twitter.
"We believe EDR can drive long-term economic value by increasing UFC fighter pay & providing them healthcare. Reaching out to Engine No. 1 to partner on this “endeavor".
Paul partnered with Woo - who owns the nutrition company HVMN - last year to create the venture capital fund "Anti Fund".
The 25-year-old has voiced his previously criticised UFC president Dana White on fighter pay several times in the past, labelling him a "selfish capitalistic motherf*****".
He told White to pay heavyweight champion Francis Ngannou "what he wants" after the Cameroonian earned just $600,000 for his title defence last weekend.
"Give this man what he wants Dana," Paul said. "Such a f***ed up company to be apart of… I got something coming soon."
Earlier this year, Paul said he would retire from boxing and fight UFC star Jorge Masvidal if White increased fighter pay, guaranteed them 50 per cent of revenue and long-term healthcare.

Paul later changed his offer after White went silent in the five day period he gave him to respond.
"Dana, my one-fight deal, I will fight for $50K, the new minimum. You make millions off of me and all of UFC fighters benefit from the new minimum rev share and healthcare," he said,
White recently denied that Paul is a "thorn in his side" despite their ongoing rivalry and refused to rule out the 25-year-old's chances of competing in the UFC.
“Would I let him (in the UFC)? Well, he can do whatever he wants to do. I don’t know. I don’t think that would ever happen but listen, I never say never anymore," he told the FULL SEND podcast.
