Facebook Founder Mark Zuckerberg Is Now Fourth Richest Person In The World

 

Last week, thanks to FB's strong quarterly performance, Mark saw his net worth increase from around $40 billion to $48 billion, practically overnight. That was enough to allow the 31-year-old tech titan's overall wealth to jump over billionaire brothers, David and Charles Koch, as well as Mexican telecom tycoon, Carlos Slim.

This week, Facebook's stock showed that it wasn't done growing. FB's share price is up another 5% as of today's closing, which tops Mark's net worth off at just over $50 billion.

Meanwhile, the last week has not been so kind to Amazon founder Jeff Bezos. Between last Thursday and today alone, Amazon's share price has declined 16%. With that drop, Jeff Bezos' net worth has been trimmed by around $7 billion. And with these moves, Bezos has slipped under Mark in terms of current total net worth, $49 billion vs. $50 billion, respectively.

So as of this writing, the only people on the planet who are richer than Mark Zuckerberg are Warren Buffett ($60 billion), Zara founder Amancio Ortega Gaona ($70 billion) and Bill Gates ($78 billion).
