The Chicago Board of Trade Building is a 44-story, 604-foot Art Deco skyscraper located in the Chicago Loop, standing at the foot of the LaSalle Street canyon. Built in 1930 for the Chicago Board of Trade, it has served as the primary trading venue of the CBOT and later the CME Group, formed in 2007 by the merger of the CBOT and the Chicago Mercantile Exchange. In 2012, the CME Group sold the CBOT Building to a consortium of real estate investors, including GlenStar Properties LLC and USAA Real Estate Company.
The CBOT has been located at the site since 1885. A building designed by William W. Boyington stood at the location from 1885 to 1929, being the tallest building in Chicago from its construction until its clock tower was removed in 1895.
