Jeff Bezos Just Got $12 Billion Richer Overnight

Jeff Bezos, the world’s richest person, got a lot richer Thursday.

The Amazon.com Inc. founder added $12 billion to his fortune as the company’s shares surged 6.3 percent to $1,614 in extended trading at 4:33 p.m. in New York — on top of a 4 percent gain during the regular session — after the retailer reported results that beat Wall Street estimates. That lifted Bezos’s net worth to $134 billion, according to the Bloomberg Billionaires Index.

The world's largest online retailer also announced it was increasing the price of an annual U.S. Prime membership to $119 from $99 starting May 11 for new members and June 16 for renewing members.
