Endeavor Reaches Agreement To Take Over 100% Ownership Of The UFC March 31, 2021 Endeavor will go from owning 50.1% of the UFC to 100% after an agreement finalized today has the talent agency taking over full controlling interest of the promotion. Thursday, a 300-page prospectus revealed that Endeavor has agreed to take control of the UFC. There will be an IPO (Initial public offering) later this year to help the agency finance the buyout. The other 49.9% of the UFC is currently owned by Silver Lake and KKR investment firms. There is no reason to believe this buyout will affect Dana White’s role as UFC president, as was the case when the Fertitta Brothers sold the promotion in 2016.
