History of Citadel 

Citadel was founded in 1990 by Kenneth Griffin, who started trading convertible bonds from his Harvard dorm room using satellite technology for live market data. By 1998, the company capitalized on hedge fund sell-offs during the Long-Term Capital Management crisis, securing undervalued assets with a unique capital-lockdown strategy. In the early 2000s, the firm’s reach expanded by hiring top traders from Enron and acquiring Amaranth Advisors’ energy portfolio.  

Despite major losses during the 2008 financial crisis, the company achieved a 62% return in 2009, showcasing resilience. In 2014, it became the first foreign hedge fund to raise yuan in China, opening doors to new investments. By 2022, the firm hit record revenues and relocated its headquarters to Miami, signaling a new chapter.
