Citadel is a global financial institution founded by Kenneth C. Griffin, operating one of the world’s largest hedge funds and a leading market-making business through its affiliate Citadel Securities. The firm uses quantitative research, advanced analytics, and high‑performance technology to trade across asset classes and provide liquidity in global markets.
Citadel and Citadel Securities are heavy adopters of advanced quantitative methods, including machine learning and algorithmic trading, to gain an edge in pricing, risk management, and execution quality. The firm invests significantly in data infrastructure, high‑performance computing, and recruiting top quantitative researchers and engineers, but it does not commercialize AI platforms or tools as standalone products.
