Overview
Ken Griffin told the Milken Institute Global Conference he will "double down" on Miami, filing a permit and adding several hundred thousand square feet of space, and said Mayor Mamdani's video prompted the move.
Mayor Zohran Mamdani posted an April video outside Griffin's 220 Central Park South penthouse promoting a pied-à-terre tax on properties worth more than $5 million that he said would raise at least $500 million.
Business leaders including Vornado CEO Steven Roth and Citadel COO Gerald Beeson sharply criticized the video, while Mamdani's press secretary Joe Calvello said the mayor wants all New Yorkers, including Griffin, to succeed.
Officials cited differing fiscal estimates, with Mamdani saying wealth taxes could provide as much as $9 billion and the city comptroller estimating roughly 11,200 second homes would yield about $500 million annually.
Mamdani said the city needs meaningful tax reform, while Griffin said Citadel may proceed with a more-than-$6 billion Park Avenue redevelopment that variously was described as creating roughly 6,000 to more than 15,000 jobs.
Analysis
Center-leaning sources frame the story around Ken Griffin's perspective by foregrounding his reaction and quotes, emphasizing business consequences and personal risk, while presenting Mamdani's tax rationale secondarily. Editorial choices—selection, placement, and inclusion of pricey penthouse detail—prioritize the billionaire’s viewpoint and omit independent policy or relocation verification.
