Once again it is not a stock exchange. Futures contracts and future options. The CBOT originally traded Grain futures, notably corn,wheat and oats. Soybean futures were added later. Financial futures were added in the 70's, making the CBOT, a truly international player in the government bond markets. Primarily with the 30 year Treasury Bond contract.
Its mostly options on futures commodities. Some of those options are euro dollar, s&p, interest rates, beans, and corn. There's one futures pit and that is the S&P.
They do not trade any stocks at the CBOT. Only futures contracts and options on those futures. There are some stock index futures that to trade there, but no indvidual stocks.
