Citadel seeks office space in New York as it awaits its new Park Avenue tower

• The hedge-fund giant Citadel is said to be in talks to lease office space on Fifth Avenue.
• The firm is awaiting the construction of its 62-story tower on Park Avenue.
• Citadel may not be able to move into the tower — its largest office location — until 2030.

Ken Griffin's Citadel is looking to lease a large office along Fifth Avenue in Manhattan, two people familiar with the transaction say.

The executives did not want to be identified because the deal is still in process and is considered confidential. The transaction may not be completed, one of the people said, noting that bargaining was not finished.

The firm, one of the largest and most successful hedge funds, is looking to take 365,000 square feet at 660 Fifth Ave., a 39-story midtown office tower that recently underwent a $400 million renovation by its landlord, Brookfield Properties.
