NYC Mayor Stands by Griffin Criticism as $6B Citadel Project Hangs in the Balance

New York City Mayor Zohran Mamdani is refusing to walk back his public criticism of billionaire hedge fund executive Ken Griffin, even as Griffin’s firm signals it could scrap a massive $6 billion development project in Manhattan, according to the New York Post.

The dispute stems from a viral video in which Mamdani highlighted Griffin’s record-setting $238 million penthouse overlooking Central Park to promote a proposed “pied-à-terre” tax targeting ultra-wealthy property owners. As the New York Post reported, Mamdani used the luxury residence as an example of high-end homes that sit largely unused while the city grapples with affordability challenges.

Despite sharp backlash from Citadel, Mamdani has doubled down on his remarks, insisting the proposal is aimed at ensuring the wealthiest New Yorkers contribute more to the city’s finances—not at personally targeting Griffin. He has framed the measure as part of a broader effort to address budget pressures and housing inequality, the Post reported.

Citadel executives, however, have pushed back forcefully. The firm’s leadership criticized the mayor’s comments as unfair and warned that the escalating rhetoric could jeopardize its planned redevelopment of 350 Park Avenue—a project expected to generate thousands of jobs and inject billions into the local economy.

According to the New York Post, Citadel’s chief operating officer, Gerald Beeson, signaled that the company is reconsidering its commitment to the project amid concerns about the city’s political and business climate.

The standoff highlights growing tension between progressive tax proposals and major financial players with significant investments in New York. Griffin, whose firm has already shifted its headquarters to Miami in recent years, has been backed by prominent business figures who warn that policies perceived as hostile to wealth could drive investment out of the city.

Still, Mamdani has indicated he remains open to discussions with business leaders while maintaining that his policy goals will not change. As the New York Post reported, the mayor continues to argue that targeted taxation on luxury, non-primary residences is necessary to make the city more affordable and fiscally stable.

With billions in potential development and thousands of jobs at stake, the clash between City Hall and one of the world’s most influential hedge funds is now emerging as a major flashpoint in New York’s economic future.
