Jeff Bezos just got a whole lot richer.
Shares of his Amazon.com Inc. surged 12% to $2,100 in extended trading at 4:16 p.m. in New York, after the largest U.S. e-commerce company reported fourth-quarter results that smashed Wall Street estimates.
Bezos, already the world’s richest person, added $13.2 billion to his fortune in about 15 minutes. At the current price, his net worth would be about $129.5 billion, according to the Bloomberg Billionaires Index.
Bezos, 56, owns about 12% of Amazon’s outstanding stock, making up the bulk of his fortune. His ownership of closely held Blue Origin accounts for about $6.2 billion. The late surge Thursday added more than $90 billion to Amazon’s market value, pushing it above $1 trillion.
His ex-wife, MacKenzie Bezos, 49, also has reason to celebrate, as she owns about 4% of the Seattle-based retailer. She started the day as the world’s 24th-richest person, with a $37.1 billion fortune.

Bloomberg’s wealth ranking officially updates after the close of each trading day in the U.S., so Amazon’s latest surge, if it holds, won’t be reflected until after Friday’s close.
