Citadel Pushback: Mamdani's Targeting of Griffin Prompts NYC Redevelopment Pause Hint

New York City Mayor Zohran Mamdani targets Ken Griffin with a pied-à-terre tax on non-primary homes over $5 million, prompting a Citadel memo that calls the move 'shameful' and hints the firm could pause its $6 billion redevelopment of 350 Park Avenue, a project expected to create thousands of construction and permanent jobs. Griffin, a major GOP donor who moved Citadel’s HQ to Miami, has long supported NYC through taxes and philanthropy; the memo defends Citadel's contributions while noting the potential economic impact of delaying the project.
