On Thursday, Facebook’s Mark Zuckerberg joined the so-called Centibillionaire Club — the gang of three people who have a net worth of more than $100 billion. The only other club members are Amazon chief Jeff Bezos and Microsoft co-founder Bill Gates.

The BBC reports that Zuckerberg was pushed into the cash stratosphere when Instagram, which is owned by Facebook, launched a TikTok competitor, sending Facebook’s share price up by more than 6 percent. Zuck owns 13 percent of the company.

It’s beyond the wildest dreams of even his early mentor, Sean Parker. In a memorable scene from “The Social Network” — the 2010 movie about the founding of Facebook — Parker, played by Justin Timberlake, warns Zuckerberg not to sell the company for $1 million: “A million dollars isn’t that cool. You know what’s cool? A billion dollars.”
