Castle Hook lease sets new peak for Manhattan office rents
Demand for top-tier office space in Manhattan is pushing rents to new highs as financial firms compete for premium locations and amenities. Castle Hook Partners has agreed to lease the top two floors at 625 Madison Avenue for up to $21.2 million a year, underscoring the strength of the luxury end of New York's office market.
Highlights
- Castle Hook signed a 15-year lease for 53,000 sq ft of penthouse space at 625 Madison Avenue at $350–$400 per sq ft, setting a new Manhattan office rent record.
- Related Companies pivoted from luxury residential to high-end office use for 625 Madison after its 2024 acquisition, achieving 67% pre-leasing—primarily from financial services tenants such as General Atlantic.
- Strong demand from hedge funds for premium office space, driven by talent competition and industry gains—macro funds up 6.8% YTD through August—continues to propel luxury leasing despite political concerns.
Record lease terms at 625 Madison
As reported by Financial Times, citing the New York Business Journal, the 15-year tenancy agreement gives Castle Hook 53,000 square feet of penthouse space at Related Companies' 625 Madison Avenue tower, with annual rent of between $350 and $400 per square foot. The hedge fund is due to move into the building in the second half of 2029.The deal surpasses the previous reported office rent record set earlier this year, when a private international family office signed a 10-year lease averaging $327.50 per square foot in a Midtown tower owned by Soloviev Group. The value of Castle Hook's lease had not previously been reported.
Related had initially planned a luxury residential tower for the site, which it bought from SL Green in early 2024, but shifted to offices instead. Chief executive Jeff Blau says the developer sees a strong premium for new, high-end office space with extensive amenities and prominent views.
The 53-storey tower overlooking Central Park is designed by British architect Lord Norman Foster and includes private dining facilities and wraparound terraces on its penthouse and amenity floor. By the end of the year, the building is expected to be 67% leased, mostly to financial services tenants, with General Atlantic taking five floors as the anchor tenant.
Finance sector demand lifts luxury offices
Castle Hook, founded in 2016 by Soros Fund Management alumnus David Rogers, currently has its headquarters in the General Motors Building on Fifth Avenue. The firm manages about $11 billion with 35 employees, according to its most recent regulatory filing, and counts Stanley Druckenmiller among its early investors.The firm operates in global macro investing, trading broad economic trends across currencies, commodities, bonds and stocks. That strategy has benefited from volatile markets, with macro funds up 6.8% for the year through the end of August, according to PivotalPath research, while Castle Hook has reportedly posted gains of about 50% last year and more than 60% the year before.
Competition for talent among hedge funds and other financial groups is helping drive demand for lavish offices as employers try to attract and retain top investors while bringing staff back to desks. New York's latest generation of office towers is responding with wellness centres, dining options and other amenities, a trend reinforced by projects such as JPMorgan Chase's headquarters unveiled in 2025.
The leasing momentum also comes despite investor concerns about local politics and the city's property outlook. Blau says tenants continue to back New York's long-term future, even as some Wall Street executives have warned that political shifts could push financial firms to consider other locations.
