Speaking via phone on Fox News with Bill Hemmer, O'Leary spoke of potentially buying the video steaming app before it goes dark on Sunday. 

When asked about a figure for the app, which is set to be banned unless it is sold, he said: 'Right now, $20 billion is on the table, cash, cash. $20 billion', when asked if that would do it he said: 'Well, I don't know.'

O'Leary said that any company that moves in to buy TikTok would be subject to fines totaling over a billion dollars a day. 

He added: 'This thing goes dark at midnight because who's going to take on a billion seven risk at midnight? 

'Who's going to do that? What counsel would advise? This is the most interesting, complicated, crazy situation I've ever been involved in. I'm really excited about it.'

His comments came after The Supreme Court allowed the ban to go into effect in the United States. 

The court handed down its decision after TikTok argued a law banning the app would violate their users' First Amendment rights. 

Last year, Congress passed a law banning TikTok unless its Chinese parent company ByteDance sells its stakes by January 19, 2025. 

U.S. officials raised concerns that the wildly popular app is a national security concern with the collection of Americans' data.  But as the clock ticked down on the deadline, no deal has materialized.

TikTok, along with some users and creators sued in an effort to block the ban. But their efforts were rejected by lower courts, leaving them with no choice but to appeal to the Supreme Court.

The Supreme Court heard oral arguments in the case on January 10, where it signaled it would not interfere with the ban going into effect on Sunday

In that decision on Friday, the country's highest court noted that the provisions of the law in question were content neutral, targeting a foreign adversary's control of a platform rather than targeting particular speech.
