Facebook Expected To File IPO Today

The world waits to find out how much Zucks & Co. are really worth.

Facebook is expected to file the necessary paperwork today for an initial public offering of between $5 billion and $10 billion. That would mean a valuation of between $75 billion and $100 billion for Facebook, making it the largest ever internet-related IPO. The IPO would mark the end of Facebook's seven years as a private company. Started in Mark Zuckerberg's Harvard dorm room in 2004, the social network has since grown to more than 800 million users. Facebook is the third-largest internet property, behind only the networks belonging to Google and Microsoft.
