Everybody knows that Google has hired investment bankers and will likely be trading by April. The question now is: Will you get pre-IPO shares?

It's a question I'm asked a lot. First, know that Google is not necessarily a slam-dunk. Yahoo! (NASDAQ:YHOO) is a formidable foe, as TheWall Street Journal highlighted yesterday in breaking down that company's "three prong" attack on Google. And Google faces other mega competitors, including Microsoft's (NASDAQ:MSFT) MSN, and even Amazon.com (NASDAQ:AMZN).

But, let's say that you still want to roll the dice on some pre-IPO shares. Initial offerings typically go down one of two ways. There's the traditional method where an investment bank sets the price of the offering and gives a big chunk to wealthy clients and institutions. Then there's the online auction, where any investor can make a bid. If you win the bid, you get shares.

Interestingly, Google may be eyeballing a combination of the two approaches (call it an "auction combo"). Reportedly, the company has hired traditional investment banks, such as Morgan Stanley (NYSE:MWD) and Goldman Sachs (NYSE:GS), as well as the pioneer of IPO auctions, WR Hambrecht & Co.

There is some precedent. Back in May 2001, when Instinet came public, CS First Boston managed the traditional part of the offering. In that particular deal, WR Hambrecht got a 17.5% allocation of the 32 million shares offered which it auctioned through its OpenIPO system.

As it turns out, WR Hambrecht & Co. elicited significant demand for the offering, with bids for over 74 million shares. In fact, while CS First Boston's initial price range was $11.50 to $13.50, the IPO was priced at $14.50, suggesting that WR Hambrecht & Co.'s Open IPO system was a critical factor in the price discovery.

Assuming that Google does allocate, say, 15% to 20% to an online auction, there is a decent chance you will get pre-IPO shares. After all, assuming the company raises $4 billion at $25 per share, and there is an auction for 20% of the amount, this would leave 32 million shares up for bid.
