Billionaire Elon Musk explained why his fight with Mark Zuckerberg did not take place.
“I thought that if the fight is at the Coliseum, then I wouldn’t mind doing it under the UFC umbrella and all that, but we wouldn’t put a ton of UFC advertising on the Coliseum because it’s a place with a lot of history. You don't want it to be like NASCAR. And then Zuck refused. Look, at the end of the day, I will fight him anywhere, under any rules,” Musk said.
