Griffin Calls Mamdani's Wealth‑Tax Video 'Creepy' and Shifts Focus to Miami

*TL;DR: Hedge‑fund billionaire Ken Griffin slammed Mayor Zohran Mamdani’s wealth‑tax video as “creepy and weird,” then announced he will double down on growing his operations in Miami rather than Manhattan.

Context Mayor Zohran Mamdani released a video outside Griffin’s $238 million New York penthouse to promote a proposed pied‑à‑terre tax. The tax would levy an annual fee on luxury homes valued over $5 million, a measure Mamdani says could raise at least $500 million for the city. Critics argue such a levy could push high‑net‑worth residents out of New York, harming the tax base.

Key Facts - Griffin described the video as “creepy and weird,” adding that it creates security risks after a nearby fatal shooting of UnitedHealthcare CEO Brian Thompson. - Mamdani’s proposal targets owners who keep wealth in New York real estate without residing there, aiming to generate $500 million annually. - At the Milken Institute Global Conference, Griffin pledged to “double down” on expanding his business interests in Miami, signaling a shift away from Manhattan. - The mayor’s office highlighted Griffin as a major employer and economic engine for the city, while maintaining that the current tax system is “fundamentally broken.”

What It Means Griffin’s public rebuke underscores the tension between New York’s effort to tax high‑value property and the city’s reliance on wealthy individuals for jobs and investment. By redirecting his growth strategy to Miami, Griffin signals that the proposed tax could influence where billionaires locate their assets and operations. If other affluent owners follow suit, New York may see a slowdown in luxury‑real‑estate demand, potentially reducing the projected $500 million revenue from the pied‑à‑terre tax.

The mayor’s broader fiscal plan includes raising the corporate tax rate from 7.25 % to 11.5 % and pursuing additional wealth‑tax measures that could bring up to $9 billion to the city budget. The success of these initiatives will hinge on whether the city can retain its high‑net‑worth residents while addressing calls for a more equitable tax system.

Looking ahead, watch how Miami’s business climate responds to Griffin’s investment push and whether New York adjusts its tax strategy to mitigate any exodus of wealthy individuals.
