CME Group represents the merger of the Chicago Mercantile Exchange (CME), the Chicago Board of Trade (CBOT), the New York Mercantile Exchange (NYMEX) and its commodity exchange division, Commodity Exchange, Inc. (COMEX). The formation of CME Group did not, however, result in any change to trading privileges for CME, CBOT and NYMEX/COMEX members.

Members of CME Group’s legacy exchanges continue to trade on the same terms as before the merger transactions. To cross-trade products at member rates, participants need to have memberships at each of the CME Group legacy exchanges.

CME, CBOT and NYMEX/COMEX membership types, fees and requirements vary, as do terms for purchasing and leasing memberships.
