Biography & Early Wealth Journey

Whether that will actually happen, not to mention whether Stallone's shares would be enough to entice McGregor back to UFC, remains to be seen. But Stallone's offer remains a more peaceful solution to the dilemma than McGregor's recent challenge to actor (or as McGregor put it, "actress") Mark Wahlberg to fight over his own UFC shares, or a similar challenge in response to a joke from comedian Conan O'Brien to fight him on the same night (Wahlberg and O'Brien are both, like Stallone, shareholders in UFC).

As humorous as challenging actors or comedians for their UFC shares may be, McGregor is still clearly serious about his desire to be compensated for his services with a stake in the company. He first reportedly pushed for a stake back in 2016, and has reiterated this demand as recently as March, when he also announced his surprise retirement from MMA. This is a dealbreaker for UFC President Dana White, though, he recently spoke on the subject in an interview with Las Vegas's CBS 8 News Now:

Primary Income Streams & Multi-Million Contracts

"He's stuck on this thing where he wants a piece of the ownership and if you look at basketball, Michael Jordan didn't own a piece of the league."

But White also seems confident that he can bring McGregor back into the fold anyway, also saying that "I think there's other ways that we can make him happy."

And even if not, there's always Sylvester Stallone.
