Billionaire Ken Griffin criticized New York Mayor Zohran Mamdani’s “tax-the-rich” targeting, saying it pushed his shift to Miami.
Ken Griffin’s decision to relocate Citadel to Miami took another turn into the public spotlight after he described a New York political attack as personally unsettling.
Speaking at the Milken conference in Los Angeles. Griffin. the founder of Citadel and Citadel Securities. said being targeted by New York Mayor Zohran Mamdani is “triggering” trauma he associates with his time in Chicago.. He also criticized Mamdani’s “tax-the-rich” video filmed outside his apartment. calling it “creepy and weird. ” and said the experience made his choice of Miami over New York feel unmistakably right.
This kind of political pressure matters to major financial firms because location decisions are not only about taxes or access to talent, but also about day-to-day operating stability, security concerns, and the broader business climate.
Griffin said Citadel previously ran out of Chicago before moving to Miami during the pandemic period.. He framed his broader relocation decision around frustrations with leadership in Chicago and Illinois. and he used Tuesday’s remarks to reinforce that Miami is where he believes the environment is more supportive of business and education policies.
He also addressed how the firm is managing its footprint in New York.. Citadel had been positioned to redevelop an office building on Park Avenue. but Griffin said Tuesday that the project’s direction remains under discussion.. At the same time, he said the company revised its Miami building plan and is pursuing a larger headquarters.
For investors and market participants, these kinds of signals can translate into more than corporate pride. Real estate shifts and redevelopments often reflect longer-term bets on where a firm expects growth, regulatory friction, and talent ecosystems to be more favorable.
Griffin’s comments extended beyond infrastructure to the personal networks that often follow big institutional moves.. He described attending an event for Palantir after the technology company relocated to Miami. and he said he has continued to socialize with friends who moved from Chicago to Florida.. “We get together and eat pizza and play cards,” he said.
At the core of Griffin’s remarks is a concern about targeting and escalation. He said he watched the mayor’s video multiple times and described it as more frightening with repetition, referencing broader concerns about extremism aimed at politicians and prominent business leaders.
In that context, the episode highlights how political communication can ripple into high-stakes business decisions, especially when global firms operate with heightened sensitivity around safety, reputation, and operating continuity.
