Citadel is a privately owned company headquartered in the US. Founded in 1990, the company employs approximately 4060 individuals, specializing in financial services. Functioning as a hedge fund and financial services company, Citadel managed over $39 billion in assets as of 2021.
On July 23, 2026, the City of Miami agreed to sell Ken Griffin a historic site across the street from the planned Citadel headquarters in the Brickell financial district, completing the billionaire’s goal of owning the entire square block. Earlier on the same day, Miami commissioners approved the no-bid sale of a 121-year-old publicly owned cottage and its lot near the Brickell waterfront to Griffin for $3 million, a decision passed without meaningful discussion. This approval ensures Griffin will own the entire block. The Dade Heritage Trust, which leases the cottage, supports the deal, with executive director Christine Rupp stating the sale provides an "amazing opportunity" for the organization to own its building and land, as the cottage and the land underneath are city-owned. This follows a July 22, 2026, announcement that the 121-year-old cottage near Griffin’s future Citadel headquarters would be relocated to Coconut Grove, as Dade Heritage Trust planned to move its headquarters from the city-owned land.
