Key Takeaways
- • Ken Griffin's Citadel responded to NYC Mayor Zohran Mamdani's public targeting of the hedge fund CEO over a proposed pied-à-terre tax on luxury properties worth over $5 million owned by non-full-time residents, signaling potential consequences for a planned $6 billion Manhattan development project.
- • Mamdani featured Griffin's $238 million Central Park South penthouse (purchased in 2019, a US residence record) in a social media video promoting the tax proposal, which the mayor claimed was "secured" despite being only a proposal by Governor Kathy Hochul with no finalized details.
- • Citadel's Chief Operating Officer Gerald Beeson warned via employee email that the planned 350 Park Avenue redevelopment—projected to generate 6,000 construction jobs and support 15,000+ permanent jobs in Midtown Manhattan—may not proceed, framing the mayor's focus on Griffin as unfair given the company's substantial economic contributions to New York.
- • The dispute centers on tax policy targeting wealthy non-residents, with Mamdani positioning the pied-à-terre tax as part of his campaign platform, while Citadel contends the company already supports New York's economy through major capital deployment and job creation.
Summary
New York Mayor Zohran Mamdani's public campaign for a pied-à-terre tax on luxury properties has triggered a sharp response from Ken Griffin and his hedge fund Citadel. Last week, Mamdani released a social media video filmed outside the Central Park South apartment tower where Griffin purchased a penthouse for $238 million in 2019—a record price for a U.S. residential property. In the video, Mamdani announced he had "secured" an annual fee targeting luxury properties worth more than $5 million whose owners do not reside full-time in the city, explicitly naming Griffin's penthouse as an example of the type of property the tax would target.
However, the proposed tax remains only a proposal by New York Governor Kathy Hochul, not a finalized policy. The mayor's use of "secured" overstated the tax's legislative status, as details of the potential mechanism have not been publicly released.
Rather than issuing a public statement, Griffin responded through Citadel's organizational channels. In an email sent to employees of Citadel LLC and Citadel Securities, Chief Operating Officer Gerald Beeson indicated that the firm's planned redevelopment of 350 Park Avenue may not proceed. The project represents a major capital commitment: more than $6 billion in total spending, with projections of 6,000 highly paid construction jobs and support for over 15,000 permanent jobs in Midtown Manhattan. Beeson characterized Mamdani's targeting of Griffin as unfair, stating that it was "shameful" for the mayor to single out Griffin as someone "not carrying their fair share of the burdens associated with New York City's often costly and wasteful spending," given Citadel's planned economic contributions to the city.
The exchange reflects broader tensions between wealthy individuals and municipal policymakers over tax policy and public investment. While Mamdani frames the pied-à-terre tax as part of a platform to address inequality among high-net-worth property owners, Citadel's response frames the dispute as a mischaracterization of Griffin's financial relationship with New York, leveraging the company's substantial planned capital expenditure as evidence of meaningful economic contribution. The outcome of this dispute may influence both the trajectory of the tax proposal and future major capital projects planned for Manhattan by major financial institutions.
