Zuckerberg made $3 billion while he sat for Congress' questions

The verdict from Wall Street is in - and investors clearly think Facebook CEO Mark Zuckerberg was the winner after ten hours of testimony in Congress Tuesday and Wednesday.

Although shares of Facebook (FB) dipped Thursday morning, they are still up nearly 3% since Zuckerberg entered Capitol Hill to face questions from the Senate Tuesday, CNN Money reports.

The stock was already rallying earlier Tuesday as investors digested the previously released prepared remarks from Zuckerberg.

Facebook's stock has gained about 4.5% since the start of trading Tuesday morning.

So Zuckerberg, who owns more than 401.4 million shares in Facebook, got nearly $3 billion richer in the past few days. His stake in the company is now worth around $66 billion.

That makes up nearly all of Zuckerberg's total net worth -- good enough to make him the seventh richest person in the world, according to real-time data tracked by Forbes.
