Billionaires Threaten NYC Exodus Over Mamdani Mayoral Bid

Grocery magnate John Catsimatidis and hedge fund manager Bill Ackman are leading the charge against Mamdani, a state Assembly member currently polling second behind former Governor Andrew Cuomo. Ackman warned that a Mamdani victory would trigger a business flight, claiming the candidate’s proposals—which include rent freezes, municipal grocery stores, and a 2% flat tax on the wealthiest 1%—would erode the city's tax base. Catsimatidis explicitly cited the state’s 184-day residency rule, stating he would reduce his time in New York to avoid the proposed fiscal policies.

Critics of the billionaires suggest these threats merely illuminate the current reality of tax avoidance among the city's elite. Social scientist Justin Feldman noted that the wealthy already utilize tracking apps to ensure they spend fewer than 184 days in New York to minimize tax liabilities. Meanwhile, political observers argue the public warnings are backfiring, with legal scholar Alan Greene characterizing the threats as a compelling argument against wealth inequality rather than a critique of the candidate. As the primary approaches, the financial sector has doubled down on supporting Cuomo, with Ackman recently contributing $500,000 to the former governor’s super PAC to preserve the status quo.
