NYC Mayor Zohran Mamdani filmed a tax-the-rich announcement outside Ken Griffin's $238 million penthouse to promote the city's first-ever pied-à-terre tax on luxury second homes worth over $5 million. Griffin's Citadel hedge fund fired back with an internal memo calling the move shameful and suggesting it shows "ignorance and disdain" toward major economic contributors. The tax is projected to raise $500 million annually, and Citadel is now re-evaluating its $4.5 billion Park Avenue office development project. This is real political theater with genuine economic stakes — Griffin controls one of the largest development projects in Manhattan, and the public spat signals tension between populist tax policy and major business operations in the city.
