New York City Mayor Zohran Mamdani is facing mounting criticism from business leaders and financial executives after a social media video promoting a proposed tax on high-value second homes singled out billionaire Ken Griffin and his Manhattan penthouse.
In the video, Mamdani stood outside Griffin’s residence at 220 Central Park South while outlining a pied-à-terre tax targeting properties valued above $5 million whose owners do not reside full-time in the city. The proposal, still under negotiation, aims to generate roughly $500 million annually to address New York’s budget shortfall and fund expanded social programs.
Griffin, founder of Citadel, characterized the video as a “personal attack and a profound lack of judgment,” warning against what he described as the “demonizing” of business leaders. He also signaled that a planned multibillion-dollar office development in Midtown Manhattan could be reconsidered.
Citadel executives echoed that stance internally. In a message to employees, Chief Operating Officer Gerald Beeson described the mayor’s approach as “shameful” and questioned the portrayal of Griffin’s contributions, pointing to the firm’s tax payments and broader economic footprint.
Several finance and business leaders have voiced support for Griffin, highlighting his contributions as both an employer and donor. Beeson also pointed to the firm’s planned redevelopment of 350 Park Avenue, which could create around 6,000 construction jobs and support more than 15,000 permanent positions in Midtown Manhattan, while contributing billions to the local economy. Griffin has also donated roughly $650 million to New York institutions, supporting healthcare, education, and cultural organizations.
Criticism has extended beyond economic concerns to the tone of the mayor’s messaging. Some executives described the video as inflammatory, noting concerns about publicly identifying a private residence in a city that has experienced high-profile violence involving corporate leaders in recent years. Steve Fulop, Chief Executive Officer of the Partnership for New York City, stated that naming individuals outside their homes “sets a dangerous precedent” and detracts from addressing the city’s fiscal challenges.
The episode has sparked a broader debate over taxation, political rhetoric and the relationship between City Hall and the business community, as officials weigh how to address fiscal challenges while maintaining investor confidence.
