Former Microsoft CEO becomes ninth member of $100B club

Steve Ballmer has seen his wealth grow by $20.1 billion this year alone.

One of the world’s most exclusive clubs just got a new member, with a second aspirant knocking on the door. Steve Ballmer, the former chief executive officer of Microsoft Corp., has a net worth of more than $100 billion, making him the ninth person in the world to reach that lofty plateau. Oracle Corp. founder Larry Ellison fell just short of making it an even 10, ending Wednesday with a fortune of $98.6 billion, according to the Bloomberg Billionaires Index. Ballmer, 65, who stepped down as Microsoft’s CEO in 2014 and now owns the NBA’s Los Angeles Clippers, has seen his wealth grow by $20.1 billion this year, while Ellison has added $18.9 billion.
