Zuckerberg just made $6B on Facebook surge

Bezos, Zuckerberg risk billions over moves in company stock

Facebook CEO 's wealth continues to balloon amid a torrid run for his company's stock.

Facebook shares spiked more than 15 percent Thursday after the social media giant's earnings reported Wednesday blew past Wall Street's most optimistic estimates. The value of Zuckerberg's Facebook stake rose by more than $6 billion as of 2 p.m. ET.

The gain brought the 31-year-old Zuckerberg's net worth above $47 billion, making him the world's sixth-richest person, according to Forbes. He passed Oracle founder Larry Ellison, who boasts a net worth of $44 billion.

Facebook shares have now climbed more than 43 percent in the last year. Its market value now sits at nearly $310 billion.

Zuckerberg will not personally enjoy most of his immense wealth. He and his wife, pediatrician Priscilla Chan, pledged last year to give 99 percent of their Facebook shares to the Chan Zuckerberg Initiative, which will funnel money into education and health care, among other issues.

Zuckerberg has previously been vocal about education and immigration reform.
