Conor McGregor said he's a billionaire in a new Instagram post.
The Irish UFC fighter reportedly made $100 million for losing to Floyd Mayweather in his sole boxing rules bout in 2017.
In addition, Forbes reports that he made $47 million in the last year.
He also makes money away from fighting thanks to his Proper no. Twelve whiskey brand.
He earns from his August McGregor clothing line, and his firm McGregor Sports and Entertainment.
