Billionaire Ken Griffin, founder of Citadel and worth about $50 billion according to Forbes, is currently in a public dispute with New York City Mayor Zohran Mamdani over a proposed tax targeting ultra-wealthy property owners and concerns about rising crime rates in the city [1]. This conflict mirrors Griffin's previous break with Chicago, where he moved Citadel's global headquarters to Miami in 2022, citing crime and economic policy issues as major factors [1].
Griffin's departure from Chicago resulted in a significant reduction of Citadel's workforce in the city, dropping from roughly 1,300 employees to a few hundred, and led to a loss of high-paying finance jobs, shrinking office space, and the withdrawal of a major civic and cultural benefactor [1]. Griffin stated, 'Chicago, over the past six or seven years, has been engulfed in a series of problems,' highlighting crime as a key issue and noting that many employees were willing to relocate due to these challenges [1].
The current dispute in New York was triggered by Mamdani's viral April 15 video promoting a proposed annual tax on second homes worth more than $5 million, specifically targeting properties whose owners do not live full-time in the city [1]. The video was filmed outside Griffin’s 24,000-square-foot Central Park South penthouse, which he purchased for a record $238 million, and mentioned Griffin by name [1]. In response, Griffin criticized the video as 'creepy and weird' during a discussion at the Milken Institute [1].
The situation in New York is described as echoing the early stages of Griffin's conflict with Chicago's leadership, suggesting potential implications for the city's financial sector and civic landscape if the dispute escalates [1].
CONCLUSION
Ken Griffin's clash with Mayor Mamdani over proposed taxes and crime concerns in New York City closely resembles the circumstances that led to his high-profile exit from Chicago. The outcome of this dispute could have significant implications for New York's financial sector, workforce, and civic life, as seen in Chicago following Citadel's departure.
