One of Wall Street’s most influential figures has unveiled his response to New York City Mayor Zohran Mamdani, following the release of what he described as a “creepy and weird” video filmed outside his $238 million penthouse.
Ken Griffin, the billionaire who founded Citadel, expressed his intention to bolster his investments in Miami rather than New York. This decision comes after Mamdani targeted Griffin in a campaign advocating for increased taxes on luxury second homes valued at over $5 million.
Griffin characterized the mayor’s video as not only “creepy” but also “frightening,” evoking memories of the political challenges that prompted his departure from Chicago.
Previously, Griffin had hinted that Citadel might reconsider its plans to redevelop 350 Park Avenue following Mamdani’s contentious social media presence.
At the Milken Institute Global Conference on Tuesday, Griffin elaborated on his strategy during a panel discussion, stating, “We moved to Miami and reconfigured our building plans to expand our office space there.”
He further explained, “The actions of New York’s mayor have conveyed to my partners, especially those in New York, that Miami is where we need to concentrate our efforts.”
‘Looking at what Mamdani did to me and more broadly is doing to the city of New York is triggering the trauma I went through in Chicago.’
Miami is already the headquarters of Citadel, which was famously moved from Chicago in 2022, citing the city’s dysfunctional government and rising crime.
Citadel has recently suggested it may rethink its expansion plans. At the conference, Griffin said Mamdani’s pointed remarks have forced him to at least scale back the firm’s New York City footprint and expand its build-out of the Miami hub.

Ken Griffin, who runs Citadel Investment, has said he is reconsidering a planned redevelopment of 350 Park Avenue in response to Mamdani’s controversial social media post
In an internal email to staff obtained by the Daily Mail in late April, Citadel’s chief operating officer, Gerald Beeson, said the firm may not proceed.
‘We are about to commence the redevelopment of 350 Park Avenue, creating 6,000 highly paid construction jobs and supporting the creation of more than 15,000 permanent jobs in mid-town New York,’ he wrote.
‘The project – if we move forward – will entail more than $6 billion dollars of spending.’
The dispute was triggered by a video posted by Mamdani promoting a so-called ‘pied-à-terre tax’ on luxury second homes.
Standing outside Griffin’s $238 million penthouse at 220 Central Park South, the socialist mayor outlined his new tax scheme, which would introduce an annual surcharge on all luxury homes in the Big Apple valued at over $5 million if they are being used as a second home.
It is projected to generate around $500 million annually in a bid to help close the city’s budget deficit.
Mamdani pointed up to Griffin’s lavish apartment as he announced the policy, stating it would specifically hit high-value residences ‘like this penthouse.’
Griffin broke the record for the most expensive home purchase in the US when he snapped up the Manhattan penthouse in 2019, but his primary residence is in Miami, Florida after relocating his hedge fund in 2022.

Griffin conceded that the video had gotten to him, saying he watched it three times in disbelief.
‘I mean like you literally look at the first time, you’re like, you gotta be kidding me. Okay?’ Griffin said at the conference.
‘And then the second time you’re like, you know what this is? Actually, this has gone from creepy to actually not really creepy; this has gone frightening.’
He’s not the only Citadel powerhouse who took issue with the video. Beeson also called out Mamdani for using the billionaire as an example in his email.
‘It is shameful that he used Ken’s name as the example of those who supposedly aren’t carrying their fair share,’ he wrote.
‘The Mayor has once again manifested the ignorance and disdain of the elite political class.’
The Citadel COO said its employees and partners have paid nearly $2.3 billion in city and state taxes over the past five years.
And its planned development would span close to 2 million square feet and support thousands of construction and permanent jobs.

On top of Citadel’s financial contributions to New York, Beeson highlighted the firm’s broader charitable involvement, noting that around 200 team members serve on the boards of local nonprofit and cultural institutions.
Meanwhile, he applauded Griffin’s personal philanthropy, saying he has directed around $650 million to causes in New York City, including the Success Academy charter schools and leading institutions such as Memorial Sloan Kettering, Weill Cornell, and NYU Langone.
Beeson isn’t the only one who has questioned Mamdani’s tactics.
After Mamdani’s clip circulated on social media, CNBC anchor Sara Eisen slammed the Democrat for calling out a private citizen and ‘demonizing’ Griffin to promote his tax policy.
‘Ken Griffin employs thousands of people in NYC and is planning to build the tallest office tower on Park Ave., investing billions more and creating thousands more jobs,’ Eisen said in defense of the billionaire.
The proposed pied-à-terre tax still needs approval from the state legislature and is expected to face strong opposition from the real estate industry.
Similar measures have been introduced in the past and ultimately failed to pass, most recently in 2019.
Any decision by Citadel on the latest plans would affect one of the largest office projects currently proposed in Manhattan.
Beeson concluded in his email: ‘For more than 25 years, our New York offices have been a vital hub of dynamism in the financial life of the city – and our country.
‘We have nearly 2,500 colleagues who have chosen to build their careers here – drawn by the opportunity to do meaningful work at the center of the world’s financial capital.
‘We understand that our hard work and success will, on occasion, make us targets for political rhetoric.
‘But it should not diminish the pride we take in building firms that will continue to help New York City thrive for decades ahead. ‘
