The Chicago Mercantile Exchange (CME) (often called "the Chicago Merc", or "the Merc") is a global derivatives marketplace based in Chicago and located at 20 S. Wacker Drive. The CME was founded in 1898 as the Chicago Butter and Egg Board, an agricultural commodities exchange. Originally, the exchange was a non-profit organization. The Merc demutualized in November 2000, went public in December 2002, and merged with the Chicago Board of Trade in July 2007 to become a designated contract market of the CME Group Inc., which operates both markets. The chairman and chief executive officer of CME Group is Terrence A. Duffy, Bryan Durkin is president. On August 18, 2008, shareholders approved a merger with the New York Mercantile Exchange (NYMEX) and COMEX. CME, CBOT, NYMEX, and COMEX are now markets owned by CME Group. After the merger, the value of the CME quadrupled in a two-year span, with a market cap of over $25 billion.Today, CME is the largest options and futures contracts open interest (number of contracts outstanding) exchange of any futures exchange in the world. The Merc trades several types of financial instruments: interest rates, equities, currencies, and commodities.
