Chicago is known for finance, manufacturing, food production, logistics, and professional services. The metropolitan area generated $886 billion in gross regional product in 2024, making it one of the largest regional economies in the world. That output is spread across a remarkably diverse set of industries, several of which have roots stretching back more than a century.
Manufacturing Still Leads the Economy
Manufacturing is the single largest industry in the Chicago metro area, contributing $105 billion to the regional economy in 2024. That figure accounts for nearly 12% of Chicagoland’s total output, putting it ahead of every other sector. The manufacturing base includes heavy machinery, electronics, chemicals, and a massive food processing operation (more on that below). Companies like Motorola Solutions and GE HealthCare Technologies are headquartered in the region, representing the higher-tech end of Chicago’s manufacturing tradition.
Finance and Derivatives Trading
Finance and insurance contributed $69.5 billion to Chicago’s economy in 2024, but the city’s influence on global finance goes far beyond that number. Chicago is home to CME Group, the world’s leading derivatives marketplace. CME Group operates four exchanges: CME, CBOT (the Chicago Board of Trade), NYMEX, and COMEX. Together, these exchanges handle futures and options contracts across six major asset classes: agriculture, energy, equity indexes, foreign exchange, interest rates, and metals. If you’ve ever heard someone reference corn futures, S&P 500 futures, or crude oil futures, those contracts are traded on Chicago exchanges.
The city’s role in finance extends to banking, insurance, and commercial real estate services. Northern Trust, Old Republic International, and Jones Lang LaSalle (one of the world’s largest commercial real estate firms) all call Chicago home.
The Food Capital of the U.S.
Chicago has a legitimate claim as the country’s food industry capital. The region’s food and beverage manufacturing sector produces $11.8 billion annually and employs more than 72,000 people across the metro area. Legacy companies like Mars, Kraft Heinz, Mondelez International (maker of Oreo and Cadbury), Conagra Brands, Kellanova, Molson Coors Beverage, and McDonald’s are all headquartered in or around Chicago. Archer Daniels Midland, one of the world’s largest agricultural commodity processors, is also based here.
The food sector is evolving, too. The region now hosts at least 23 alternative protein manufacturers and 46 bioengineered food producers, building a newer innovation layer on top of the traditional food processing base.
Professional Services and Technology
Professional, scientific, and technical services made up $86.9 billion of Chicago’s 2024 economy, while the tech sector contributed another $83.9 billion. Combined, these two categories represent nearly 20% of the region’s output. Chicago has become a significant tech hub over the past decade, with major offices for Salesforce, Google, and other national firms, along with a growing base of startups. The professional services category covers consulting, legal, accounting, and engineering firms that serve both local companies and national clients.
Life Sciences
Life sciences added $45.6 billion to the regional economy in 2024, rounding out the top five industries. GE HealthCare Technologies, which makes medical imaging equipment and healthcare IT systems, is a Fortune 500 company headquartered in the metro area. The sector spans pharmaceuticals, medical devices, and biotechnology research.
A National Freight and Logistics Hub
Chicago’s geographic position at the center of the country makes it the most important freight hub in North America. More railroad lines converge in Chicago than in any other city on the continent. In 2023, Illinois originated 132.4 million tons of freight rail traffic and received another 102.4 million tons. Intermodal freight (goods transferred between rail and truck) dominated both categories, reflecting Chicago’s role as the place where long-haul rail shipments get loaded onto trucks for final delivery. To put the volume in perspective, it would have taken 23.1 million trucks to move the freight that traveled by rail through Illinois in a single year.
The city also has O’Hare International Airport, consistently one of the busiest airports in the world for both passenger and cargo traffic. United Airlines Holdings is headquartered in Chicago, reinforcing the city’s role as a transportation center.
Fortune 500 Concentration
Chicago’s industrial diversity shows up clearly in its Fortune 500 roster. The metro area is home to at least 14 Fortune 500 headquarters spanning food (Kraft Heinz, Mondelez, Conagra, McDonald’s, Kellanova, Molson Coors), agriculture (Archer Daniels Midland), airlines (United), energy (Exelon), healthcare technology (GE HealthCare), real estate (Jones Lang LaSalle), financial services (Northern Trust, Old Republic International), and technology (Motorola Solutions). Few cities outside of New York can match that breadth across so many different sectors.
