Facebook may be the third largest Internet company in the United States, with an estimated value of $41 billion, according to Bloomberg.
Facebook's privately held shares are trading at $16 a share, which puts its estimate worth at about $41 billion, higher than eBay, which is currently worth $39.3 billion. Facebook is still trailing behind Amazon, worth $74.4 billion, while Google still maintains the top spot worth $192.9 billion.
However, analysts won't know exactly how much Facebook is worth until their shares are available in a public offering. Currently Facebook only trades on SecondMarket, which does not publicly release trade values, but one man who did not want to be identified said Facebook is trading at $16 a share, which is almost up 50% since last month.
The massive jump could be due to Facebook's big announcement, Project Titan, an email service offering from Facebook. The "Gmail killer" is expected to have a strong social network integration embedded in its email service, a serious threat to Microsoft, Yahoo and Google.
