Greek-American billionaire John Catsimatidis has threatened to leave New York and relocate his business to Florida following the election of Zohran Mamdani as mayor. Catsimatidis cited the incoming administration’s plans for affordable city-run grocery stores that would sell subsidized essentials to ease the cost-of-living crisis experienced by many in New York. The Red Apple Group owner, whose estimated net worth stands at $4. 8 billion, had initially vowed to move his operations to New Jersey but reversed course after Democrat Mikie Sherrill won the state’s gubernatorial race this week, according to Forbes. Who is Catsimatidis and why is he against Mamdani’s.
