Summary
Castle Hook Partners, a hedge fund founded by Soros Fund Management alumnus David Rogers in 2016, has secured what JLL describes as a record lease rate for Manhattan office space. The firm signed a deal for 53,000 square feet spanning the penthouse and top two floors of 625 Madison Avenue, a 53-story Midtown tower owned by Related Companies. The lease commits Castle Hook to annual rent between $350 and $400 per square foot, translating to up to $21.2 million annually. The fund will relocate from its current headquarters in the General Motors Building on Fifth Avenue, with occupancy expected in the second half of 2029.
The lease represents a material increase over the prior 2026 record of $327.50 per square foot, achieved when an international family office signed a 10-year lease in a Soloviev Group–owned Midtown property. The new deal underscores accelerating demand at the ultra-premium end of Manhattan's office market, where tenants are willing to pay unprecedented rates for newly constructed, highly amenitized Class A space. The building, designed by British architect Lord Norman Foster in collaboration with Gensler, will feature private dining facilities, wraparound terraces, and panoramic Central Park views—amenities that command premium valuations in the current environment.
Related Companies' decision to develop office space rather than pursue its original plan for luxury residential reflects a strategic bet on sustained institutional demand. Chief Executive Jeff Blau cited the existence of "real premium" pricing for "new, properly amenitised, high-end office with incredible views," positioning the company to capture value from financial services and technology sector competition for talent and office quality. This leasing momentum extends across the broader Manhattan market: 313 office leases at $100 per square foot or higher were signed in 2025, substantially exceeding 2024's record of 212 such leases, indicating that high-end office demand remains robust despite broader office market headwinds elsewhere in the city.
