As New York City debates how to fix its budget shortfalls and rising costs, billionaire investor Bill Ackman has issued a warning that could reverberate far beyond the five boroughs.

He argues that aggressive tax policies targeting the ultra-wealthy risk driving away the very individuals who bankroll much of the city’s prosperity.

At the center of this growing tension is Zohran Mamdani, a state assemblyman pushing to significantly raise taxes on multimillionaires and billionaires. His proposals include a “pied-à-terre” tax aimed at secondary homes worth millions of dollars, such as Citadel CEO Ken Griffin’s $238 million Manhattan penthouse.

Mamdani’s message is blunt: the richest New Yorkers must pay more to fund city priorities like childcare and social programs.

Ackman, however, sees danger ahead. In a Bloomberg interview, he cautioned that by making political targets of people like Griffin, the city risks losing more than it could ever hope to collect from new taxes.

“If your goal is to make New York City financially solvent,” Ackman said, “what you don’t want to do is drive out the Ken Griffins of the world.”

Griffin himself has hinted at serious consequences. He told CNBC that being publicly singled out by Mamdani placed him and his family at risk. More importantly, he warned that the city’s stance is affecting his business decisions.

Griffin revealed to Fox Business that he is reconsidering major New York projects, including a multibillion-dollar development, and is leaning toward expanding operations in Miami instead.

“We need to double down on our bet in Miami,” Griffin said.

“We want to be in a state that embraces business, embraces education, embraces personal freedom and liberty.” His comments echo the sentiment behind a broader migration of capital and talent out of high-tax states.

Ackman, a longtime supporter of New York’s economic vitality, sees the current anti-wealth rhetoric as a self-inflicted wound. He emphasized that Griffin “is a major job creator of some of the highest-paid jobs in the city,” someone who has “spent a lot of money here” and given millions to local hospitals, museums and cultural institutions. Losing even a handful of such individuals, he said, could create a ripple effect across the city’s budget.

The math supports Ackman’s warning. According to research from the Empire Center for Public Policy and the Tax Foundation, the top 1 percent of New York taxpayers generated 40 percent of the city’s income tax revenue in 2022 and 41 percent of the state’s total.

Ackman estimates that the top 10 percent of New Yorkers are responsible for about three-quarters of all city tax revenue once property and income taxes are combined.

If even a small share of that group packs up and leaves, the city would face a steep fiscal imbalance. “You’re not going to make it more affordable by getting rid of the biggest drivers of tax revenues for the city,” Ackman noted.

The logic is simple: the fewer high earners remain, the heavier the tax burden on everyone else.

Mamdani and his supporters argue that their proposals correct systemic unfairness rather than punish success. They point to large wealth gaps and growing housing costs as proof that billionaires’ assets should fund relief for working-class families.

Yet the challenge lies in balancing that populist message with the reality that New York’s economy depends on keeping its biggest taxpayers in place.

Ackman cites California as a cautionary tale. Years of high taxes and escalating regulation have driven many business leaders and entertainers to more tax-friendly states like Texas and Florida.

Though motivations for relocation vary, the loss of those top earners has undeniable fiscal impact. Ackman claims that New York risks repeating that mistake if it prioritizes politics over pragmatism.

For now, Ackman maintains that he intends to stay and “fight to make sure New York City is a great city,” even as he criticizes policies that, in his view, undermine its economic foundation.

But his message to leaders like Mamdani could not be clearer: drive away top taxpayers and you jeopardize the financial health of every neighborhood, every public service, and every family that depends on a functioning city budget.

Whether the warning is heeded remains to be seen. If high earners begin to flee, New York could face declining tax receipts, service cuts, and a shrinking business base. If officials somehow strike a balance that raises fairness without triggering flight, the city might manage both growth and affordability.

Ackman and Griffin have come to symbolize that debate — one side warning of a fiscal cliff, the other demanding greater redistribution.

Either way, New York’s economic future may depend on how it navigates this widening divide between populist politics and the practical realities of wealth creation.
