Illinois’ diverse economic base is a mix of manufacturing, agriculture, and biotechnology.
In 2017, the fifth most populous state was home to 50 Fortune 500 companies, including Walgreens Boots Alliance (owner of Walgreens), Boeing, State Farm Insurance, Archer Daniels Midland, Allstate, and McDonald’s. Other notable companies headquartered in the Prairie State include United Airlines, Kraft and Heinz. In recent years, Illinois has expanded from its agricultural roots to become a leader in clean energy. The Prairie State ranks fifth for installed wind turbine capacity and is third largest producer of ethanol. Roofstock currently operates in the Chicago investment property market.
