However, on October 27, 2017, Bezos again surpassed Gates on the Forbes list as the richest person in the world.
Amazon CEO Jeff Bezos replaces Bill Gates as wealthiest person in the world, topping $105 billion.
Bezos came under fire past year when The New York Times questioned his level of philanthropic giving.
Bezos is the largest shareholder of Amazon, the world's biggest online retailer. Bezos also owns Blue Origin, a travel business that intends to take tourists to explore space and the Washington Post newspaper.
The majority of Bezos' fortune comes from the 78.9 million Amazon shares he owns.
Bezos surpassed Gates in October past year with a net worth of $93.8 billion and his fortune crossed $100 billion for the first time a month later when the holiday shopping season kicked off on Black Friday. Adjusted for inflation, that would be $148 billion today. The trend continued Tuesday as shares closed at $1,252.70, and the company's market capitalization was above $600 billion. Gates is second, followed by Warren Buffett at $87 billion.
