Facebook CEO and founder Mark Zuckerberg lost $6.06 billion in Facebook stock value on Monday amid the news of Cambridge Analytica using the data of 50 million users without their permission, reports CNBC.

Since then, the shares of the social media firm plunged as much as 8%. With the news breaking on Monday, Facebook shares were down by 2.6% year-to-date. The stock pared losses slightly during the Monday trading.

However, despite the losses, Zuckerberg is still ranked as the fourth richest man in the world, according to Bloomberg.

Zuckerberg and his affiliated institutions such as the Chan Zuckerberg Initiative have more than 403 million shares of Facebook stock. The shares are still worth about $68.5 billion.

Cambridge Analytica, a political data analytics firm, had worked on Facebook ads for President Donald Trump during the 2016 presidential election.

Facebook later blocked the firm's app in 2015 and announced last week on Friday that it suspended the firm for bluffing about deleting user data.

Despite the giant insisting that they have followed the mandate to protect the user data, the scuffle has questioned their tech regulations.
