I would like to subscribe to GlobalFoundry
I don't think IBKR offers IPO. In any case, IPO allocation are handled by underwriters, unless you are a very good client, most likely you won't get a good price for hot stocks.
If you have decent money with a broker/bank, like a private bank client who retail trades, you often could get in on IPOs, probably not huge allocations or the huge oversubscribed ones, but have gotten allocations in the past.Nobody has that for retail.
