Summary
Billionaire hedge fund manager Bill Ackman escalated his public opposition to New York City Mayor Zohran Mamdani, describing the mayor's policies as fundamentally misguided for the city's economic health. Speaking on the podcast "Money Rehab," Ackman stated: "I'm not a fan. He's very smart, very charismatic, very good at politics, but I think the decisions he's making are very bad for New York."
The core of Ackman's criticism centers on Mamdani's taxation strategy targeting high-net-worth individuals. Ackman highlighted the April 15 video in which Mamdani promoted a pied-à-terre tax on luxury second homes, filming himself outside Citadel founder Ken Griffin's $220 Central Park South property. Ackman argued this confrontational approach toward wealthy residents creates a counterproductive dynamic, stating: "All the various things that Mamdani wants to pay for require revenues from the likes of people like Ken Griffin. So if you scare away Ken Griffin or discourage the Ken Griffins of the world from being in New York City, it's a disaster for New York."
Ackman characterized Griffin as "a massive driver of New York City economic value," noting that Griffin is now "increasing his presence in Miami and diminishing his presence in New York"—a pattern he warned would accelerate if current policies continue. Rather than endorsing tax increases to address fiscal challenges, Ackman positioned himself as favoring efficiency improvements, stating: "I don't think the country or New York City has a revenue problem. I think we have an efficiency and waste problem."
When asked whether he would consider running for mayor himself, Ackman offered a measured non-commitment, saying: "I would say possibly, but I think I could achieve a lot more by helping a very talented person do that job." This statement positions Ackman as a potential kingmaker in future NYC politics while maintaining distance from direct candidacy. The exchange reflects the escalating friction between New York's financial elite and Mamdani's administration over competing visions for urban fiscal policy and economic competitiveness.
