The CEO of major hedge fund Citadel announced plans to expand the company’s Miami operations during a financial industry conference this week, following what he described as inappropriate behavior by New York City’s mayor.
Ken Griffin told attendees at Tuesday’s 2026 Milken Institute Conference that his firm is expanding its Miami office building plans, stating they are “doubling down” on their Florida presence.
The announcement came as Griffin addressed questions about an incident involving New York City Mayor Zohran Mamdani, a democratic socialist politician who recorded a video outside Griffin’s residential building in April. The mayor’s video, which carried the message “Happy Tax Day, New York. We’re taxing the rich,” was filmed directly in front of Griffin’s penthouse property.
Griffin characterized Mamdani’s video recording at his residence as “creepy and weird” during his conference appearance.
