White told TMZ Sports in a June 22 interview that he has been communicating with the two social media execs in recent days and both have indicated that they plan to fight in Vegas.

"Talked with Mark and Elon last night, both guys are absolutely dead serious about this," White said. "They both said, 'Yeah, we'll do it.' They both want to do it," he added.

White said he expects the fight "would be the biggest fight ever in the history of the world, bigger than anything that's ever been done," and would bring in hundreds of millions of dollars that would likely go to charity.

"It would break all pay-per-view records. These guys would raise hundreds of millions of dollars for charity. You don't have to be a fighting fan to be interested in this fight. Everybody would want to see it," the UFC president continued.

White noted that the biggest fight of all time was Floyd Mayweather and Conor McGregor. That fight took place in 2017 and Mayweather defeated his rival.
