The former Chicago Mercantile Exchange (CME) (NYSE and Nasdaq: CME), often referred to by Chicago traders as "the Merc," is a global futures and options exchange that in July 2007 acquired the Chicago Board of Trade to become CME Group. CME's futures and options offerings, which are about 75 percent electronically traded on the CME Globex electronic trading platform, include interest rates, equities, currencies, commodities, and alternative investment instruments including weather and real estate derivatives.
Volume at the exchange in 2017 was 1.8 million, down 2.5 percent from the previous year. 
CME was founded in 1898 as the Chicago Butter and Egg Board as a not-for-profit company. In 1919, its name was changed to the Chicago Mercantile Exchange. Early planners included C.E. McNeil, S.E. Davis and O.W. Olson. On the first day of trading as the CME, 3 contracts traded and a total of 8 were traded for the week.
It was after World War I that public participation of the markets was allowed.
Although the CME claims in various marketing materials to have "invented" financial futures, in fact the now defunct International Commerce Exchange, founded in 1970 by members of the New York Produce Exchange (with which it soon merged), and located in New York, was the first exchange to trade currency futures, beginning on Apr. 23, 1970, two years before the Chicago Mercantile Exchange.
From its not-for-profit membership organization roots, the CME on Nov. 13, 2000, became the first U.S. financial exchange to demutualize into a shareholder-owned corporation. In December 2002, CME became a publicly traded company.
In October 2006 the exchange announced that CME and cross-town rival, the Chicago Board of Trade, intended to pursue a merger, which in July 2007 was consummated. The merged corporation is CME Group. In March of 2008, the CME Group purchased the New York Mercantile Exchange for $8.9 Billion dollars. 
In 2008, the Chicago Board Options Exchange (CBOE) and CME reached a $1 billion settlement on a long-running a court case regarding who owns the (CBOE). The settlement ended an almost two-year lawsuit that had prevented the CBOE from merging with another exchange or going public. The settlement provided full CBOT members with an 18 percent stake in the CBOE and $300 million in cash, terms worth roughly $1 billion with a $4 billion valuation of the options market. To qualify for the settlement, CBOT members had to have valid trading rights at the CBOE and own 10,251 shares of the CME Group, which was formed in 2007 when the CME bought the CBOT. Rejected settlements ranged between $850 million and $1.3 billion.
(See CME Group for additional historical highlights.)
Through the years, the CME has moved several times to accommodate the growth of the exchange. Though the exchange maintains its offices on Wacker Drive in Chicago, in 2008, floor trading of CME products was consolidated with those of the Chicago Board of Trade, which merged with CME in 2007. The history of the exchange's office locations includes:
- 20 S. Wacker: 1983 to Present
- 444 West Jackson: 1972 to 1983
- 110 North Franklin: 1928 to 1972
- Lake and Wells: 1912 to 1928
- South Water Street: 1898 to 1912
