Don't compare this to GOOG. GOOG was leaded by big brokers. As for IBKR, it is lead by the worst one out there. Just look at past dutch auction IPO by WR Hambrecht. I don't recall IPO lead by WR Hambrecht did well at all.

The line that customers can buy into it make me think. Why would the IPO syndicate release such valuable shares to the general public? They are not a charity...
