Managing the Legal Department of the World’s Most Profitable Hedge Fund

Episode description:

John is joined by Shawn Fagan, the Chief Legal Officer of Citadel LLC, and a key legal figure at Citadel Securities. Citadel is the most profitable hedge fund globally while Citadel Securities is a leading market maker, processing nearly one-third of U.S. equities and options trades. They discuss Shawn’s insights into the unique legal challenges of these rapidly growing organizations. Shawn has essentially four clients: Citadel, Citadel Securities, founder Ken Griffin, and Griffin’s family office. His responsibilities extend beyond legal oversight to include regulatory affairs and compliance and reflect the complexities of modern finance. Shawn’s journey to Citadel was unconventional. He started as a litigator at Bartlett Beck, a boutique trial firm, where he spent nearly half his time in trial. He participated in high-profile cases, including Bush v. Gore, but ultimately realized that trial work was not his passion. A chance meeting with Ken Griffin led to an in-house opportunity at Citadel, where he has been for 20 years. In that time, Citadel has grown from 1,000 employees with $12 billion in AUM to 4,900 employees with $65 billion in AUM. The focus of his role at Citadel is building the right teams to meet the demands of rapidly growing markets around the world, developing technology to ensure regulatory compliance across billions of dollars of transactions every day, and maintaining consistent standards in an organization that is growing as rapidly as Citadel. Citadel has engaged in several high-profile legal battles, including lawsuits against the SEC and IRS, reflecting Citadel’s willingness to challenge regulations it views as unreasonable and unduly burdensome. In retaining outside counsel, Shawn looks for lawyers with a strategic vision who can articulate a clear path to winning cases.
