Google is to go public within the next few days, possibly by the end of today.
According to the WallStreetJournal's recent article Google Is Expected to Announce Plans for Initial Public Offering, where it reads:
Internet-search pioneer Google Inc. plans to announce within days that it will push forward with an initial public offering, according to people familiar with the matter....
Rumors around the Mountain View, Calif., company's IPO have swirled through markets since October. Based on early chatter among bankers, the offering could value Google at as much as $25 billion, and spread nearly $100 million in fees across Wall Street. Last fall, some of Google's prospective advisers estimated the valuation of the company could be in line with other Internet leaders. Those include Yahoo Inc., valued at $38 billion, Amazon.com Inc. at $20 billion and eBay Inc. at $54 billion.
