Amazon CEO Jeff Bezos, the richest man in the world, lost a fortune in one evening, CNBC reported

“Amazon reported third-quarter earnings Thursday that disappointed investors and sent Amazon stock spiraling down as much as 9% in after hours trading. As of 6pm ET, the stock was down 6.6%, or $118 a share,” the source noted.

If the loss of this evening persists after tomorrow's market closes, Bezos will lose his title as world’s richest person to Microsoft co-founder Bill Gates.
