Updated from 1:08 p.m.Google filed Monday to list its shares on the Nasdaq Stock Market, ending months of speculation about where the hot search engine company's stock will trade once it comes public. The company said in a filing with the Securities and Exchange Commission that it would seek to list its shares on Nasdaq, which has long enjoyed favored status with Silicon Valley. The company didn't say how many shares it would sell or when, or what its ticker symbol would be. In the Monday filing, which marks the third amendment to the public offering document that Google first filed April 29, the company also supplied more details about the nontraditional auction process it will be using to distribute its shares. In the new filing, Google raised the possibility that bidders will have to reconfirm their bids to keep their spot in the auction. The company even added a bit of boilerplate to its offering document, a perfunctory nod explaining why it is going through with the IPO in the first place. Even before Google filed for its $2.7 billion public offering, the IPO already ranked among Wall Street's most eagerly anticipated deals. In its original filing, the company said it would list either on the Nasdaq or on the rival New York Stock Exchange. While the Nasdaq has for years been the public market incubator of most technology firms, the NYSE has been eager to gain big technology stock listings. But, confounding the NYSE's efforts to gain a greater foothold among listed technology companies, many of the great tech success stories of recent years, from Microsoft ( MSFT) and Intel ( INTC) to Yahoo! ( YHOO) and Cisco ( CSCO), have maintained their Nasdaq listings even after they attained blue-chip status. In its latest filing, updating an earlier amendment filed at the SEC on June 21, Google says it may require bidders to reconfirm their bids under two possible conditions: if more than 15 business days have elapsed since the bidder submitted his or her bid, or if there is "a material change" in Google's prospectus that requires it to be recirculated.
