The UFC made headlines last summer, when reports surfaced that it had sold for $4 billion.
According to Forbes, former owners Frank and Lorenzo Fertitta retained a stake in the MMA organization and have now sold off their remaining shares at a $5 billion evaluation.
Their remaining equity in the UFC was around 5.8%.
It’s unclear how much they made on the current exit of the company, but Forbes estimates that the brothers’ net worth is around $2 billion each.
The Fertitta brothers acquired UFC for just $2 million in 2001, during a time when it was criticized as a violent sideshow.
Obviously, it grew over time into a credible athletic sport, helping produce stars like Ronda Rousey and Conor McGregor, who recently fought Floyd Mayweather in a cross-sport boxing match that generated hundreds of millions of dollars.
The UFC is currently controlled by entertainment conglomerate WME-IMG, which led the 2016 buyout and has held a majority stake in the company.
