If you work at Citadel and decide the grass is greener at a rival fund, you’d better be comfortable watching from the sidelines for a while. Ken Griffin’s hedge fund now requires some investing staff to sign non-compete agreements lasting up to two years, a move that effectively benishes top talent from the industry for the length of a presidential campaign cycle before they can join a competitor.

The firm has been gradually tightening these restrictions. As of January 2025, Citadel extended non-compete clauses to 21 months for certain portfolio managers. Senior portfolio managers and quantitative researchers face the full 24-month treatment. Similar terms apply at Citadel Securities, the firm’s market-making arm.

The talent war behind the paperwork

Citadel isn’t doing this because it enjoys bureaucracy. The hedge fund industry is in the middle of an aggressive hiring war, with rival firms dangling eye-popping signing bonuses and buyouts of deferred compensation to poach top performers. When your business model depends on proprietary trading strategies and the people who execute them, watching a star portfolio manager walk across the street to a competitor is roughly equivalent to handing over the playbook.
