NYC Mayor's Tax Day Video Targeting Billionaire Ken Griffin Sparks Business Backlash

A Tax Day video posted by New York City Mayor Zohran Mamdani on April 15 has ignited a fierce backlash from the business community, prompting fears of an accelerated corporate exodus from the city. The video, which promoted a new tax on luxury second homes, specifically featured the $238 million Manhattan penthouse of billionaire hedge fund CEO Ken Griffin, who subsequently called the mayor’s tactic "creepy and weird" and reaffirmed his company's focus on expanding in Florida. The controversial one-minute video was filmed outside Griffin’s Central Park South residence and posted to the social media platform X, where it has garnered over 52 million views. In it, Mayor Mamdani announced a new pied-à-terre tax, an annual fee on luxury properties valued at more than $5 million whose owners do not reside in the city full-time. "When I ran for mayor, I said I was going to tax the rich. Well, today, we're taxing the rich," Mamdani declared in the video, explaining the tax is designed for "those who store their wealth in New York City real estate but don't actually live here." The proposal, which the mayor’s office estimates could raise at least $500 million annually, is intended to help close the city’s projected $5 billion budget deficit. However, the direct targeting of Griffin, founder of the hedge fund Citadel, drew immediate and sharp criticism from business leaders who viewed it as a reckless and personal attack in an era of heightened political tensions. Speaking at the Milken Institute Global Conference in Beverly Hills, California, in early May, Griffin did not mince words. He described the video as "frightening" and said it solidified his decision to "double down" on growing his business interests in Miami rather than Manhattan. "Mamdani has made it very clear—New York does not welcome success," Griffin stated during a panel discussion. He also raised concerns about security, noting that such pointed rhetoric could agitate extremists. The fallout extended beyond Griffin’s personal condemnation. Following the video's release, Citadel’s Chief Operating Officer, Gerald Beeson, suggested that the firm's plans for a major new skyscraper at 350 Park Avenue could be reconsidered. This potential reversal puts thousands of jobs and significant future tax revenue at risk, amplifying concerns that the mayor's approach could be counterproductive to the city’s economic health. The incident with Citadel is not isolated. It taps into a broader trend of financial firms and wealthy individuals leaving New York for lower-tax states. According to reports, New York has lost firms managing over $1 trillion in assets in the last few years, with many relocating to Florida and Texas. Private equity giant Apollo Global Management, for example, recently announced plans to open a "second headquarters" outside of New York, with CEO Mark Rowan stating that "New York does not have a monopoly on talent." Mayor Mamdani’s office has defended the policy and the video. The mayor argued that wealthier New Yorkers must contribute more to the city’s finances and noted that other properties subject to the proposed tax include luxury condos owned by a “Saudi prince” and a “Russian auto dealer.” In a statement, Mamdani’s press secretary, Joe Calvello, described the city's current tax system as "fundamentally broken" and "unsustainable and unjust." While defending his policy, Mamdani also attempted to extend an olive branch, stating, "I want New Yorkers to succeed. I want them to build businesses, to grow our economy and to create good paying jobs. And Ken Griffin has been a part of that as an important employer and business leader in our city." The public feud between Mayor Mamdani and Ken Griffin is more than just political theater; it's a clear signal to business owners about the operational risks in New York. In our experience, when political rhetoric becomes openly hostile towards wealth creation, it creates a chilling effect that goes far beyond the specific tax being proposed. For every high-profile firm like Citadel that publicly reconsiders its footprint, we see dozens of mid-sized companies quietly accelerating their plans to relocate to more business-friendly states like Florida or Texas. The decision isn't just about the tax rate; it's about stability, predictability, and feeling valued by local government. An environment perceived as antagonistic can be the final push for a company already weighing the costs and benefits of staying.

As the debate continues, the New York business community will be closely watching whether the pied-à-terre tax proposal advances and if other major employers follow through on threats to scale back their presence in the city. The long-term consequences of this increasingly fraught relationship between the mayor's office and the city's financial engine remain a critical question for New York's economic future.
