Summary
Ken Griffin is advancing a transformational office development at 350 Park Avenue in Manhattan, with the project moving through municipal approval processes and financing stages. The 62-story supertall tower, designed by Foster + Partners, will deliver 1.8 million square feet of commercial office space and is slated for completion in 2032. The City Council unanimously approved the 1,600-foot structure, clearing a major regulatory hurdle for the initiative.
Citadel and Citadel Securities, both Griffin-controlled entities, have committed as anchor tenants for approximately 850,000 to 900,000 square feet—representing roughly half the tower's rentable space. This substantial internal commitment provides significant revenue stability and underscores Griffin's conviction in the project's viability as a flagship headquarters for his financial services operations. The $4.5 billion development carries substantial financial backing, with the development team actively closing a $3.3 billion construction loan—the largest single construction loan for a Manhattan office tower, according to project communications.
The 350 Park Avenue project is positioned to achieve the city's second-highest office rents upon lease-up, reflecting both the building's premium location on Park Avenue and its institutional-grade specifications. To maximize the development footprint, Griffin acquired additional land at 51st Street for $40 million, demonstrating strategic commitment to the project's scale and market positioning. The tower will include a new public concourse, meeting municipal requirements for public benefit in exchange for zoning approvals.
The development proceeds despite broader headwinds in the Manhattan office market and concurrent municipal dynamics in New York City governance. The project represents a significant capital deployment in New York's commercial real estate sector and serves as a bellwether for institutional investor confidence in premium Manhattan office space anchored by creditworthy, long-term occupants.
