Amazon’s Jeff Bezos is worth over $100 billion

Jeff Bezos is worth $100.3 billion, as Amazon shares jumped more than 2 percent on optimism for Black Friday sales. Online purchases for the day are up 18.4 percent over last year.

The $100 billion milestone makes Bezos, 53, the first billionaire to build a 12-figure net worth since 1999, when Microsoft Corp. co-founder Bill Gates hit the mark.

Bill Gates, 62, who has a net worth of $86.8 billion according to the Bloomberg index, would be worth more than $150 billion if he hadn’t given away almost 700 million Microsoft Corp. shares and $2.9 billion of cash and other assets to charity, according to an analysis of his publicly disclosed giving since 1996.

Bloomberg has a billionaire wealth tracking index for daily updates of the top 100 richest people.
