Summary
Ken Griffin disclosed plans to substantially expand Citadel's presence in Miami, citing New York City Mayor Zohran Mamdani's recent tax-focused video as the direct catalyst for the decision. Speaking at the Milken Institute Global Conference on Tuesday, Griffin told CNBC that Citadel has filed permits with Miami and added "several hundred thousand square feet of new space" in a new building, with intentions to create significantly more jobs in the Florida city over the coming decade as a "direct consequence" of the mayor's action.
The Citadel CEO characterized Mamdani's video as "in poor taste" and accused the mayor of turning him "into a political puppet." Griffin also invoked the 2024 assassination of UnitedHealthcare CEO Brian Thompson—killed outside a Midtown Manhattan hotel near his penthouse—when asserting that the mayor's messaging had "put me in harm's way." This comparison amplified the stakes of the dispute beyond typical regulatory or tax policy disagreements, linking political messaging directly to personal security concerns.
Despite his objections to the mayoral video, Griffin indicated Citadel would likely move forward with its controversial Park Avenue redevelopment project, valued at more than $6 billion and projected to generate over 15,000 permanent jobs in New York City. He acknowledged that this decision has become "a real topic of debate" but suggested the company would ultimately proceed.
Mayor Mamdani's office responded through press secretary Joe Calvello, affirming the mayor's support for business growth and job creation while defending the substance of the tax critique. Calvello stated that Mamdani "wants all New Yorkers to succeed," including business owners and Griffin specifically, but reaffirmed the fundamental argument: "our tax system is fundamentally broken. It rewards extreme wealth while working people are pushed to the brink."
The exchange reflects mounting tension between New York City's political leadership and major financial sector employers over wealth taxation and income inequality, with Griffin's Miami expansion announcement serving as a tangible economic response to perceived political hostility in Manhattan.
