SAN FRANCISCO — Amazon CEO Jeff Bezos has passed Warren Buffett as the second richest American this year on the Forbes 400 list of the richest people in the United States.
Bill Gates, co-founder of Microsoft, remained at the top of the list, as he has for years, with $81 billion.
The surprise was Jeff Bezos, who took second place due to a run up in Amazon stock that added $20 billion to his net worth, more than anyone on the list. The Forbes list, published earlier this month, put his worth at $70.7 billion.
Amazon's stock has seen a sharp rise in the last six months, from a low of $474 in February to a high of $844 on October 5, though it has since come down. The stock (AMZN) closed Tuesday at $817.65.
Warren Buffett, CEO of Berkshire Hathaway, fell to third place, with $64.9 billion. Buffett had held second place below Bill Gates for 15 years.
Next on the list came Mark Zuckerberg, co-founder and CEO of Facebook, with $55.4 billion. He pushed Larry Ellison, CEO and founder of Oracle, out. Ellison fell out of the top three for the first time since 2007 with his current net worth of $48.5 billion.
The rankings are slightly different for the world as a whole. Gates still retains the number one spot, but Spanish business magnate Amancio Ortega came in second with $76 billion. Bezos continued in the number three slot, with Buffett and Zuckerberg behind him. The other difference is Mexican businessman Carlos Slim Helu, at number six with a net worth of $49.3 billion.
