Chicago is America's third city by population and one of its most diverse, resilient job markets. The Windy City combines a world-class financial services sector (the Chicago Mercantile Exchange, Chicago Board Options Exchange, and futures trading ecosystem), a massive healthcare industry, the Midwest's largest tech hub, and a logistics and manufacturing base anchored by its position as America's rail and highway crossroads.

Chicago's quantitative trading ecosystem
Chicago is uniquely the global capital of quantitative and algorithmic trading. Firms like Citadel, Jump Trading, DRW, Akuna Capital, and Belvedere Trading collectively employ thousands of quantitative developers, data scientists, traders, and financial engineers. For mathematics, computer science, and engineering graduates, Chicago's quant trading sector offers some of the highest starting salaries anywhere in finance — often $150,000–$300,000+ total compensation for quantitative developers and researchers straight from graduate school.
Chicago salary context
Chicago salaries are competitive — typically 10–15% below New York and San Francisco for equivalent professional roles, but with a substantially lower cost of living. Chicago's real estate market is significantly more affordable than coastal cities, and Illinois has a flat state income tax rate. The financial calculus often strongly favours Chicago for professionals in financial services, law, and healthcare over similarly-compensated NYC or Bay Area roles.
