CME GROUP INC.

The Chicago Mercantile Exchange (CME), was founded in 1898 as a nonprofit corporation. In 1919, it established its clearing house. In 1982, CME introduced the first successful stock index futures contract, helping change equity risk management and creating today's equity index derivatives market. In 2000, CME demutualized and became a joint stock company. In 2002, CME Holdings Company, the parent company of CME, became a public company via an initial public offering.

In June 2007, the company, in partnership with Dubai Holding and Oman Investment Authority, launched the Dubai Mercantile Exchange, of which it owns 33%.

In July 2007, CME merged with the holding company for the Chicago Board of Trade, founded in 1848, in an $8 billion transaction that created the world's largest financial market, and became CME Group Inc., a CME/Chicago Board of Trade Company.

In August 2008, CME Group acquired New York Mercantile Exchange (NYMEX), owner of both the NYMEX exchange and the Commodity Exchange (COMEX), for $8.9 billion in cash and CME Group stock.

In February 2010, CME Group agreed to purchase 90% of Dow Jones & Company's financial-indexes business, including the Dow Jones Industrial Average. CME Group and Dow Jones & Company subsequently contributed the Dow Jones Indexes to the formation of S&P Dow Jones Indices, with CME Group receiving a 24.4% ownership interest and Dow Jones & Company receiving a 2.6% ownership interest in the joint venture. In April 2013, CME Group purchased the Dow Jones & Company interest for $80 million, increasing CME Group's interest in S&P Dow Jones Indices from 24.4% to 27.0%.

In May 2010, the 2010 flash crash was caused when Navinder Singh Sarao, a British financial trader, used spoofing algorithms to place orders for thousands of E-Mini S&P futures contracts via CME's Globex platform. He later replaced or modified those orders at least 19,000 times before they were cancelled. The event led to the implementation of coordinated cross-market trading curbs; CME's Globex platform had automatically halted trading, while the New York Stock Exchange did not.
