It's well-known that Amazon CEO Jeff Bezos is working on a venture to take tourists into space, but his wealth is already out of this world. Had he held on to that money, his net worth today would be well over $150 billion. That is about 17 per cent of the online book-selling company that he founded in a Seattle garage in 1994. Most of Bezos' wealth comes from his Amazon holdings, tying his net worth to market fluctuations.
Bezos surpassed Gates in October a year ago with a net worth of $93.8 billion and his fortune crossed $100 billion for the first time a month later when the holiday shopping season kicked off on Black Friday. If adjusted for inflation, that cumulative total would now be over $144 billion in 2018. He has given away nearly 700 million Microsoft shares and $2.9 billion of cash and other assets since 1996, according to an analysis of his publicly disclosed giving.
Bezos came under fire a year ago when The New York Times questioned his level of philanthropic giving. In the third position is Facebook's Warren Buffet, with a net worth of $87.2 billion, while Mark Zuckerberg and Amancio Ortega round out the top 5 with $77.5 and $76 billion, respectively.
