Citadel's Chicago Legacy
Citadel Securities was founded in Chicago in 2002 and was headquartered there for two decades. The firm's roots in Chicago — a city with a deep trading culture built on the futures exchanges — shaped its early development and culture. In 2022, Citadel Securities announced its headquarters relocation to Miami, though it maintains offices in Chicago.

Chicago Derivatives Markets Connection
Chicago is home to the CME Group and the Cboe Global Markets, which operate major derivatives exchanges. Citadel Securities is active in options and futures markets through its derivatives trading operations. The intersection of Citadel's equity market-making and its derivatives activities in Chicago-connected markets gives it a broad market footprint.
