Top 20 Richest men in the world

Richest billionaires in the world.

Amazon CEO Jeff Bezos briefly became the richest person in the world when the markets opened on July 27, 2017, according to Forbes. With a fortune of $90.6 billion, he became the first person to top a net worth of $90 billion. But by the time the markets closed, he had been dethroned again. 

While Forbes updates their list of the world's billionaires in real time as markets fluctuate, the magazine also releases a more static list each year. The total net worth of these money-makers when 2017's list was released in March was $7.67 trillion.
