According to a filing report with securities regulators back in April, Bezos owns nearly 17 percent of Amazon. In his life, Gates has reportedly donated $31.1 billion through the end of 2016, according to Forbes.
Forbes' real-time list of billionaires ticked over today following a surge in Amazon share prices, putting Bezos' estimated wealth at $91 billion, with Gates on an entirely respectable $90 billion.
But when Amazon's stock opened up 1.6% on Thursday, this added enough to move past Gates. At that time, the company was worth about $1.6 billion, only a fraction of Bezos's current personal wealth. His net worth has soared from $18.4 billion in 2012, growing by $70 billion in the last five years, including a $45 billion increase since 2015. Amazon leads the cloud-computing industry, but faces increasing competition from Microsoft and Google parent Alphabet.
That makes Bezos the seventh person to hold the title of richest person in the world and the third American, according to Forbes, which has tracked fortunes since 1987.
And speaking of fun, answer me this: hypothetically, if a real person was going to become a supervillain, wouldn't that real person be a lot like Jeff Bezos?
However, it also depends on whether the values of their non-stock assets have changed or not.
