Rumors of Facebook pending initial public offering are growing after the social network froze trading of its stock on secondary markets.
While Facebook is not a publicly traded company, select shares of the Menlo Park-based company can still be purchased on so called secondary markets.
Usually they are sold in high volume to high end traders.
But Facebook won't approve or reject any transactions on the secondary market through Friday, which is causing some analysts to predict that the company is preparing to go public.
Facebook would not comment on the story to multiple outlets.
Mark Zuckerberg's company is widely expected to go public at some point this year and many expect it to be the largest IPO ever with a valuation somewhere around $100 billion.
