News Summary:

On May 1, 2026, Ken Griffin, founder and CEO of Citadel, criticized socialism, asserting that "soaking the rich doesn't work" and questioning its viability in American society, after New York City Mayor Zohran Mamdani, a Democratic socialist, singled out Griffin's $238 million penthouse. Earlier the same day, wealthy New Yorkers protested an initiative by Mayor Mamdani and Governor Kathy Hochul to introduce a tax on second homes valued at $5 million or more. Concurrently, Citadel is accelerating its Brickell tower expansion in Miami, pushing for a larger office footprint for its headquarters, which will house Citadel and Citadel Securities in a redesigned 54-story, 1.7 million-square-foot office tower. Also on May 1, Citadel Energy Marketing, the merchant trading arm of Ken Griffin’s Citadel, expanded its natural gas pipeline transportation capacity on a key interstate conduit from the Rocky Mountains to Arizona by 37%, positioning itself for anticipated growth in Southwest gas demand. This followed an April 30 meeting between Griffin and Governor Hochul, during which he labeled the proposed pied-à-terre tax a "profound lack of judgment."
