Jeff Bezos Will Get Even Richer Off Twitter IPO

Amazon CEO Jeff Bezos' venture capital firm was an early investor in Twitter and will presumably make a big profit from the company's upcoming IPO.

Bezos Expeditions, his personal investment vehicle, was among a handful of firms that made a second round investment in Twitter in 2008. The amount his firm invested is unclear.

Twitter filed a confidential IPO on Thursday, an option under the JOBS Act to avoid public scrutiny for companies making less than $1 billion in revenues. According to estimates, Twitter's valuation falls in the $10.5 billion to $14 billion range.
