Billionaire hedge fund founder Ken Griffin, Vornado Realty Trust, and Rudin have finalized a joint venture to develop a 66-story Manhattan office skyscraper at 350 Park Avenue, securing a $3.3 billion construction loan for the project [1]. Under the joint venture structure, an affiliate of Griffin (Citadel Enterprise Americas LLC) will own 60% of the project, while Vornado holds 36% and Rudin retains 4% [1]. The multibillion-dollar construction loan is being provided by seven financial institutions: Wells Fargo, JPMorgan Chase, Bank of America, BMO Bank, ING Capital, PNC Bank, and Standard Chartered Bank [1].
The 1.9 million-square-foot tower, designed by architecture firm Foster + Partners, will rise approximately 1,400 feet above Park Avenue and feature luxury amenities [1]. Notably, Citadel Enterprise Americas LLC has already signed a lease for 1.05 million square feet of office space in the skyscraper, representing more than half of the building's planned office space, while approximately 850,000 square feet of office space on the upper floors will be available for lease [1]. Construction is already underway [1].
The project moves forward despite earlier controversy between Griffin and New York City Mayor Zohran Mamdani [1]. In April, Mamdani recorded a video calling out Griffin as a wealthy hedge fund owner subject to the city's pied-à-terre tax on high-value residential properties whose owners don't live in the city full-time [1]. Griffin responded by calling the personal attack "creepy and weird" and stating it demonstrated a "profound lack of judgment" [1]. Citadel executives had suggested the new office space could become a casualty of Mamdani's policies, though Mamdani eventually softened his rhetoric and thanked Griffin for his contributions to the city [1].
The development includes financial contributions tied to New York City's Greater East Midtown rezoning initiative, with the project contributing a combined $150 million toward the maintenance of St. Patrick's Cathedral and Saint Bartholomew's Church through the purchase of development rights [1].
CONCLUSION
Ken Griffin's $3.3 billion financing for the 350 Park Avenue office tower represents a significant real estate investment and demonstrates confidence in Manhattan's office market despite recent challenges [1]. The project's completion is bolstered by Citadel's substantial pre-lease commitment of over half the building's office space, providing substantial revenue certainty for the joint venture partners [1].
