Billionaire Ken Griffin Diverts Jobs from New York to Miami Over Mayor's Tax Campaign
New York, Thursday, 7 May 2026.
Citadel CEO Ken Griffin is diverting New York jobs to Miami after Mayor Mamdani filmed a ‘tax the rich’ campaign outside Griffin’s $238 million penthouse, citing severe safety concerns.
A Costly Political Stunt
On April 15, 2026, New York City Mayor Zohran Mamdani released a social media video to coincide with Tax Day, advocating for a new pied-à-terre tax [3][4][5]. The proposed levy targets non-primary luxury residences valued at over $5 million and is projected to generate at least $500 million annually for the municipality [3][4][5][6]. To illustrate his policy agenda, Mamdani filmed the broadcast outside 220 Central Park South, specifically highlighting the penthouse purchased by Citadel CEO Ken Griffin in 2019 for $238 million [3][4][5][6]. The property remains the most expensive home ever purchased in the United States [4][7].
The Economic Ripple Effect on New York
The immediate economic fallout from this political friction is substantial. Griffin announced that Citadel will drastically scale back its planned job creation in New York City, shifting its focus southward [1][3]. Prior to this dispute, Citadel had been advancing a $6 billion redevelopment project at 350 Park Avenue, an ambitious office tower expected to create upwards of 15,000 permanent jobs [1][2][3][5][7]. While Griffin noted at the conference that he will “probably go through with the building” eventually, he confirmed the massive capital investment is now a “real topic of debate” internally [6][7].
Miami’s Gain and the Chicago Precedent
As New York’s competitive edge faces mounting scrutiny, Florida is poised to capture the diverted capital. Griffin stated that Citadel will add “far more jobs in Miami over the next decade” as an “immediate and direct consequence” of Mamdani’s video [1][3][6][7]. To accommodate this growth, Citadel has filed permits to expand its Miami headquarters by several hundred thousand square feet [6]. The firm recently scrapped plans for a hotel at its Brickell headquarters, opting instead to construct a 54-story, 1.7 million-square-foot (approximately 157935.1 square meters) all-office tower [6].
The Debate Over Wealth Taxation
In response to the escalating corporate exodus, Mayor Mamdani’s administration has doubled down on its fiscal philosophy [3][4]. On Wednesday, May 6, 2026, mayoral press secretary Joe Calvello issued a statement asserting that while the mayor wants all New Yorkers—including major employers like Griffin—to succeed, the current tax system remains “fundamentally broken” [3][4]. The administration argues that the status quo is “unsustainable and unjust,” rewarding extreme wealth while pushing working-class citizens to the financial brink [3][4]. Mamdani claims that his broader taxation agenda, which includes raising the corporate tax rate from 7.25 percent to 11.5 percent—an increase of 4.25 percentage points—could generate up to $9 billion for city initiatives [4].
