Chicago Mercantile Exchange
The Commodity Futures Modernization Act of 2000 legalized U.S. trading in single-stock futures, and two exchanges began operations in November 2002. OneChicago began as a joint venture of the Chicago Board Options Exchange, the Chicago Mercantile Exchange, and the Chicago Board of Trade. The other exchange, NQLX (owned by Euronext.liffe), closed in December 2004 and assigned its remaining contracts to OneChicago. In 2006, IB bought 40% of OneChicago, with Chicago Mercantile Exchange and CBOE each retaining 24% and the remainder belonging to the Chicago Board of Trade and OneChicago management. (The Chicago Mercantile Exchange and the Chicago Board of Trade merged in 2007 to form CME Group.) The OneChicago exchange closed in September 2020.
