Jeff Bezos' net worth reached $105.1 billion.

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.

Jeff Bezos' net worth reached $105.1 billion Monday on the Bloomberg Billionaires Index as Amazon.com shares added to a 12-month surge that's lifted the online shopping giant's market value by almost 57 percent.

Amazon shares have risen 6.6 percent this year, with a report showing the Seattle-based company captured 89 percent of online spending among dominant holiday retailers in the five-week period beginning the day after Thanksgiving in the U.S.


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.
