As it is Sunday afternoon here and I feel a bit bored, I just wanted to discuss here whether you consider IB's targeted market cap of ~10 bln USD "justified". Let's look for a few comparisons (I know it cannot be compared this way, but the figures speak too nicely!): - NITE, the market maker, is only 1.5 bln. And this firm is not too different! They have the same problem - both suffer from insider trading ! - Order Routing: GLTrade, which has superior software (IB even routes Asia through them!) connected to ~100 marketplaces around the world, is valued around 500 million. - NYSE + Euronext is worth around 15 bln. Charles Schwab is roughly in the same league.
