New York City Mayor Zohran Mamdani refused to back down from his tax plan Wednesday, even as hedge fund billionaire Ken Griffin made clear he is redirecting investment dollars away from the city and toward Florida, a move that could cost New York thousands of construction jobs and billions in development.
At a Wednesday press conference, a reporter confronted Mamdani with Griffin's blunt assessment: the Citadel CEO and founder had called the mayor's earlier video "creepy" and "weird," said Mamdani's targeting of him was "very unfair," and announced he would be "doubling down" on investments in Florida rather than New York City.
Mamdani's response was a textbook exercise in progressive deflection. He acknowledged Griffin as "a major employer in our city", then pivoted straight back to class-warfare talking points, as Breitbart News reported.
"I want all New Yorkers to succeed. That includes business owners and entrepreneurs, who creating good paying jobs who make this city the economic engine, not just of our state, but frankly of our country. That also includes Ken Griffin, who is a major employer in our city. That does not negate the fact, however, that our tax system is fundamentally broken. It rewards extreme wealth, while working people are pushed to the brink."
In other words: I want you to succeed, I just want more of your money first.
The feud traces back to April, when Mamdani released a video announcing a pied-à-terre tax that featured Griffin's penthouse. The mayor singled out a specific private citizen, one of the largest employers in his own city, to sell a populist tax hike. That choice had consequences.
Griffin did not take it quietly. Speaking at the Milken Global Conference, the billionaire drew a sharp line between New York and the state that welcomed his firm's relocation from Chicago.
"When we moved from Chicago, there was a debate between New York and Miami; it's unquestionably true that we made the right choice. I'll leave it at that. And now, what the Mayor of New York has made clear to my partners, and principally, my New York partners, is that we need to double-down on our bet in Miami because we want to be in a state that embraces business, that embraces education, that embraces personal freedom and liberty, and that embraces the opportunity for people to live in the American dream and a dream of earned success, not a dream of redistributive handouts that leave people dependent on government for their lives."
That is not a vague threat. That is a CEO explaining his capital allocation strategy to a room full of investors, and explaining it as a direct response to the mayor's conduct.
Griffin had previously been reported to be considering backing out of a $6 billion project in New York City, one that would help create roughly 6,000 highly paid construction jobs. The scale of that potential loss should give any city leader pause.
Mamdani showed no such pause. The reporter at Wednesday's press conference asked directly about potential job losses and whether the mayor was "looking at ways to build up." Mamdani offered no specifics on job creation or economic development. He offered rhetoric about "meaningful tax reform that includes the wealthiest New Yorkers paying their fair share."
The pattern is familiar for anyone who has followed Mamdani's early tenure in City Hall. Big promises, bold language, and a conspicuous lack of attention to downstream consequences.
Gerald Beeson, Citadel's chief operating officer, told the Daily Mail that the mayor's decision to name Griffin in the video was "shameful."
"It is shameful that he used Ken's name as the example of those who supposedly aren't carrying their fair share."
Beeson's use of "supposedly" is worth noting. The Citadel executive did not concede the premise that Griffin or other wealthy New Yorkers are undertaxed. He challenged it. And his boss followed through, not with a press release, but with investment decisions that carry real weight.
This is the part of the equation that progressive politicians routinely miscalculate. Capital moves. People move. Businesses move. Florida has no state income tax. New York's combined state and city tax burden is among the highest in the nation. When a mayor publicly targets a billionaire employer by name and announces new taxes on the wealthy, the billionaire does not sit still and absorb the hit. He moves his money to Miami.
Mamdani's approach to high-profile confrontations has become a defining feature of his administration. Whether the subject is federal law enforcement or hedge fund executives, the mayor appears to prefer the fight itself over any resolution that might follow.
The reporter's question Wednesday went to the heart of the matter: what conversations has the mayor had with Griffin since the video? Has he spoken with him? What about job losses?
Mamdani did not answer those questions directly. He said he wanted New York City "to be one that working people can actually afford to live in" and called for "meaningful tax reform." But he offered no evidence that he had engaged with Griffin, no plan to replace the jobs or investment at risk, and no acknowledgment that his own video may have accelerated the very capital flight he should be working to prevent.
That gap, between the mayor's stated concern for working people and his apparent indifference to the jobs those people might lose, is the story.
Griffin moved Citadel from Chicago to Miami. He chose Miami over New York once already. Now Mamdani has given him every reason to deepen that bet. And the construction workers who might have built a $6 billion project in New York City are the ones left holding the bag.
The mayor's instinct to frame problems in ideological terms rather than confront their practical dimensions is not new. It is a habit that costs real people real money.
Griffin's Milken Conference remarks were not just about Mamdani. They were about competing visions of governance. Griffin described Florida as a state that "embraces business," "embraces education," "embraces personal freedom and liberty," and offers "the opportunity for people to live in the American dream." He contrasted that with what he called "a dream of redistributive handouts that leave people dependent on government for their lives."
That framing is a direct indictment of the policy direction Mamdani represents. And it is backed by action: Griffin told his partners, specifically his New York partners, that they need to double down on Miami.
When a city's own mayor drives its largest private employers toward a rival city, the question is not whether the tax system is "fundamentally broken." The question is whether the mayor is breaking it further.
Mamdani's rising national profile, he has hinted his politics could go national, suggests he may view this fight as a feature, not a bug. Picking a public battle with a billionaire plays well on social media. It plays less well when the billionaire takes his billions elsewhere and the construction workers never get hired.
The mayor said he wants a city where "working people can actually afford to live." But working people need jobs. They need the kind of large-scale development projects that a $6 billion investment creates. They need employers who choose New York over Miami.
Mamdani's "Tax the Rich" plan may sound appealing in a campaign video. But the rich have options. They have accountants, lawyers, private jets, and standing invitations from governors in states with friendlier tax codes. The people who do not have those options are the ones Mamdani claims to champion, the workers, the small business owners, the families who cannot relocate on a whim.
When the wealthy leave, the tax base shrinks. Services get cut or debt rises. The cost lands on the people who stay. That is not theory. That is the documented history of every high-tax jurisdiction that pushed too hard and watched its top earners walk.
New York City has been through this before. It can ill afford to go through it again, especially not because its mayor wanted a viral moment more than he wanted a functioning economy.
You can tax the rich, or you can keep them. Mamdani seems determined to find out what happens when you try both at once.
