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.
