Citadel is a privately owned company headquartered in the US. Founded in 1990, the company employs approximately 4060 individuals, specializing in financial services. Functioning as a hedge fund and financial services company, Citadel managed over $39 billion in assets as of 2021.
Citadel CEO Ken Griffin reaffirmed plans on July 10, 2026, to move the firm from New York City to Miami, also backing Rubio for 2028. Earlier on July 10, speaking at a Goldman Sachs Apex Symposium, Griffin warned that losing access to Taiwanese semiconductor chips could trigger a "Great Depression," causing an 8% decline in U.S. gross domestic product within six months, as Taiwan Semiconductor Manufacturing Co. Ltd. microchips are embedded in "every high-end product." During the same symposium, audio published by Fortune on July 10 revealed Griffin criticized Sen. Bernie Sanders (I-Vt.) and New York City Mayor Zohran Mamdani, suggesting they "read a damn history book" while arguing high taxes and poor public services are pushing Wall Street firms out of New York. Previously, on July 9, Griffin reversed his earlier stance on artificial intelligence, forecasting a "golden age of entrepreneurial activity" powered by AI, after having dismissed the technology as "garbage" at Davos five months prior.
