Mark Zuckerberg
INTERNATIONAL - Mark Zuckerberg added $6.2 billion to his net worth Thursday, jumping two places to No. 5 on the Bloomberg Billionaires Index, after his Facebook Inc. posted revenue that beat Wall Street estimates, sending its shares soaring.

Zuckerberg, Facebook’s 34-year-old co-founder, vaulted over Amancio Ortega of Spain and Mexico’s Carlos Slim, who are now ranked sixth and seventh, respectively, on the list of the world’s 500 richest people. Shares of Menlo Park, California-based Facebook surged 11 percent to $166.69, the biggest one-day gain in three years, boosting Zuckerberg’s fortune to $65.6 billion.

Amazon.com Inc. founder Jeff Bezos added $3.8 billion on the day and remains the planet’s wealthiest person with a $142.1 billion fortune, ahead of No. 2 Bill Gates, with $95.8 billion. Bezos overtook the Microsoft Corp. co-founder for the top spot 15 months ago.

Only four of the 174 Americans on the Bloomberg ranking saw their fortunes decline in January as U.S. markets rallied from a late-December slump. The S&P 500 Index surged 7.9 percent for the month, its best in more than three years. The world’s 500 richest people added a total of $308 billion to their wealth in January as global markets also gained.
