World's richest man: Jeff Bezos

Jeff Bezos, Amazon CEO, became the world's richest man, defeating Bill Gates, co-founder Microsoft.

The recent surge in Amazon stock has pushed Bezos' fortune to over $90 billion, vaulting him past Bill Gates. Bezos has been chasing Gates for the number one spot for a few years now and finally succeeded in superseding him. But this dream run was short-lived. On Thursday, Bill Gates was crowned again as the world's richest man as Amazon stocks went down by 1%. 

Because their wealth is largely a result of the shares they own of their company and its fluctuating price, it is possible that the wealthiest title may go back and forth between Gates and Bezos.
