Mark Zuckerberg owns 400 million shares of Facebook, and his net worth has fallen by $5 billion. Zuckerberg still owns about $69.5 billion worth of the platform’s stock. That’s enough to make him the sixth-richest person in the world, according to Forbes. Forbes data showed Zuckerberg fell by 6.7 percent — a loss of $5.1 billion — in just a few hours on Monday.
Facebook stock has recovered, and as of Friday, Zuckerberg's wealth has increased by $2.5 billion, according to the Bloomberg Billionaire Index. Despite the rebound, Facebook has taken a significant temporary hit to its net worth, taking its total to $2.2 billion so far in 2018.
The Facebook founder isn't the only tech billionaire to take a sudden hit on Monday. Shares of Alphabet, Google's parent company, fell 4%, and the net worths of company founders Larry Page and Sergey Brin fell by about $1.5 billion, according to Forbes.
