Griffin Says He’s Doubling Down on Miami Amid Mamdani Feud

Ken Griffin said he plans to make Citadel’s Miami tower even bigger after New York Mayor Zohran Mamdani name-checked the billionaire in his pledge to charge more taxes on second homes.

“We went to Miami and revised our building plan to make it a bigger office building,” Griffin said in an interview Tuesday at the Milken Institute Global Conference in Beverly Hills. “What the mayor of New York has made clear to my partners, and principally my New York partners, is that we need to double down on our bet in Miami.”
