Bezos's net worth surpassed $100 billion on Friday, Bloomberg reported. Amazon shares hit a record on Black Friday — one of the year's busiest shopping days — joining a broader stock market rally.
Bezos, the world's richest man, owns about 78.9 million shares of Amazon, according to a Nov. 14 filing. That stake alone is worth more than $93.5 billion as of Friday's closing price of $1,186 a share.
Amazon is not his only business venture. Bezos also invests in start-ups, and owns The Washington Post and space company Blue Origin. These companies can be difficult to value, but Forbes still puts Bezos's fortune at $99.6 billion.
Bezos is followed on the list of wealthiest people by Bill Gates and Warren Buffett. They've both already allocated significant chunks of their fortunes to philanthropy, a goal that Bezos is also exploring.
