About Citadel Securities
Citadel Securities is a leading global market maker and financial services firm founded by Kenneth Griffin and headquartered in Miami, Florida.

As a market maker, Citadel Securities continuously quotes bid and ask prices across thousands of securities, enabling fast and efficient trade execution for market participants at scale.

The company also has significant global fixed-income market-making operations, providing liquidity in government bonds and other debt securities.
