Background
Citadel Securities is one of the world's largest market makers, handling roughly 25% of all US equity volume. Founded by Ken Griffin, it is the trading arm of the Citadel enterprise (separate from Citadel the hedge fund).
In early 2026, Citadel Securities took the unusual step of publishing a formal rebuttal to Citrini Research's viral AI displacement report. Citadel called the thesis an "intelligence crisis of misunderstanding macroeconomic fundamentals," arguing that Indeed job-posting data still showed strong demand for software and knowledge worker roles.
The rebuttal was notable because Citadel rarely engages publicly with research reports. That it felt compelled to respond signalled how seriously institutional markets were taking the AI displacement narrative.
