My impression is that prop trading at any bank that took US government money during the financial crisis (Goldman, JP Morgan, BA/Merril Lynch etc..) is now banned from prop trading. JP Morgan got into trouble as they tried to hide this in the London office (e.g., the London Whale trade). Prop trading is, of course, what hedge funds do. Also, firms like Blackrock which never took money.
