(CNN) - Amazon founder and CEO Jeff Bezos has narrowly dethroned Microsoft co-founder Bill Gates as the world's richest person.
According to Forbes and Bloomberg, Bezos's net worth surpassed $90 billion on Thursday.
If Amazon's stock price holds through Thursday trading, Bezos will officially bump Gates, who has topped the rich list since 2013.
Most of Bezos' fortune is in Amazon stock, and the company's market value passed $500 billion this week.

A fluctuation in either Amazon or Microsoft stock price could cause Bezos to quickly lose his new title.
