Mark Zuckerberg just became the sixth-richest person on Earth.
The Facebook Inc. founder saw his fortune rise $5.5 billion in early trading Thursday as the world’s biggest social network delivered another quarter of record revenue. That gives the 31-year-old a net worth of about $47 billion, enough to surpass the $45.3 billion holdings of brothers Charles and David Koch, according to the Bloomberg Billionaires Index.
Facebook reported on Wednesday that fourth-quarter sales were up 52 percent to $5.84 billion and net income had more than doubled to $1.56 billion from a year earlier. More than 1.59 billion users are now logging on every month, according to the company.
The five billionaires that remain above the tech entrepreneur in the ranking — Bill Gates, Amancio Ortega, Warren Buffett, Jeff Bezos and Carlos Slim– have lost a combined $24 billion so far this month through Wednesday trading as global equities slump amid dimming investor expectations of global growth.
