The latest jump has pushed Bezos' fortune definitively above the high reached by Microsoft's Bill Gates in 1999. The Amazon founder passed Gates in October 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.
Gates, 62, would have a net worth of more than $150 billion if he'd held onto assets that he's given away, largely to the Bill & Melinda Gates Foundation. He has given away almost 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 also controls closely held space exploration business Blue Origin and The Washington Post.
