Citadel Securities

Founded in 2002 by billionaire Kenneth C. Griffin, Citadel Securities is a premier global market maker that provides vital trading liquidity to retail and institutional clients. Driven by advanced algorithmic systems, the firm handles roughly 40% of all U.S. retail equity volume, continuously pricing and executing trades to keep capital markets efficient and liquid around the clock.

Corporate Structure: Part of the Citadel Empire

Citadel Securities operates as a distinct trading entity under the broader Citadel LLC corporate umbrella. While the parent organization manages both sides of the empire, it strictly separates its operations into two independent financial giants:

1. Citadel Securities: The market-making arm that uses its own balance sheet to facilitate trades.
2. Citadel (Hedge Fund): The asset management arm that pools outside investor capital to execute investment strategies.

Both entities are anchored under the Citadel LLC framework, sharing the strategic vision of founder Kenneth C. Griffin.
