According to a recent article from Bloomberg and Forbes, Jeff Bezos CEO of Amazon became the world’s richest man of all time. While Forbes reported that Bezos was worth $105 billion, Bloomberg reported that he was worth $106 billion dollars.

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.

The previous record was held by Microsoft founder Bill Gates with $100 billion in 1999.
