Summary
Billionaire Ken Griffin is clashing with New York City Mayor Zohran Mamdani over taxes targeting the ultra-wealthy and intensifying crime, reviving tensions that drove him to pull his business and billions out of Chicago. Griffin moved his firm’s global headquarters from Chicago to Miami in 2022, a departure that showed how quickly jobs, investment, and influence can follow when a major financial player leaves. The move marked Griffin’s break from Chicago, where he built one of the world’s most powerful hedge fund and market-making operations.
Our Reading
As expected, the matter has reached another stage.
Ken Griffin and Zohran Mamdani are locked in an escalating fight, echoing the early stages of Griffin’s break with Chicago. Griffin criticized Mamdani’s viral video promoting a proposed tax on second homes worth more than $5 million as “creepy and weird.” Mamdani’s video singled out Griffin’s 24,000-square-foot Central Park South penthouse, purchased for a record $238 million. Griffin is reassessing Citadel’s plans for a $6 billion office tower at 350 Park Avenue, while doubling down on its expansion in Miami.
Griffin’s departure from Chicago has been followed by a steady erosion of one of its most prominent corporate anchors. The dynamic is now resurfacing in New York.
The clash highlights a widening divide between progressive ambitions in major cities and the financial leaders who help drive their economies.
Griffin’s ability to relocate his business and influence has become a familiar pattern.
