If they're going to do it this year, Google has to tip its hand by filing a financial disclosure this week. Estimates of the IPO range from $20-25B, as in Billion, at the end of the first day. Along with the two founders, the current owners of Google shares in the privately held company include AOL, Yahoo, Tiger Woods, Henry Kissinger, the inventor of Napster, the founder of Ebay and the founder of Netscape. What I didn't know was that Stanford University gets a big slice since the Google search technology is owned by the university (college students working under a school funded grant) and that Stanford licenses the technology back to Google for a royalty and some stock.
