Jeff Bezos is now the richest person of all time. That should put an Amazon smile on his face.

The Amazon CEO's net worth reached $105.1 billion Monday, according to Bloomberg's billionaire tracker. That eclipses the record previously held by Microsoft founder Bill Gates.

Forbes, the other major tracker of the net worth of the world's richest, put Bezos' net worth at a mere $104.4 billion.

The majority of that net worth comes from the 78.9 million shares of Amazon stock he owns. Shares of Amazon (AMZN) climbed 1.4% Monday, adding about $1.4 billion to his net worth.

Shares of Amazon (AMZN) are up nearly 7% so far in this year after rising 56% in 2017.

Bezos' other holdings include the Washington Post and Blue Origin, a private space travel business that intends to take tourists to space.
