Just like in a typical auction, the highest bidders win in an OpenIPO auction but there are important differences.

WR Hambrecht + Co has used OpenIPO to take a number of companies public including Morningstar, Interactive Brokers Group, Overstock. com, Ravenswood Winery, Clean Energy Fuels and, most notably, functioned as co-manager to take Google public in 2004 using the Dutch auction system. Many traditional investment banks have balked at the idea of using an auction process such as OpenIPO to engage in public securities offerings as this new method allows for equal access to the allocation of shares and eliminates the “behind the scenes” dealings of shares and favorable treatment often found in conventional IPOs. Despite other banks’ resistance to using this method, however, OpenIPO has been gaining traction in recent years and has been utilized for over 20 public offerings to date.
