General Atlantic anchors Related's 625 Madison with five floors

General Atlantic has signed a long-term lease for more than 150,000 square feet at Related Cos.' under-construction 625 Madison Ave., Connect CRE reports, and will occupy five floors as anchor tenant when the 53-story tower opens in 2029, using the space as its global headquarters for a New York team of more than 330 professionals.

Five floors and more than 150,000 square feet put General Atlantic's average occupancy above 30,000 square feet per floor, the kind of full-floor layout that column-free plates are built to serve, so the scale of the commitment tells the quality story as clearly as the renderings do. The building itself, designed by Foster + Partners between 58th and 59th Streets, is being sold on Central Park views, an all-electric LEED Platinum shell, and restaurant and luxury retail at its base. Related bought the site in 2024 and demolished a 1956-vintage structure that had once been headquarters for Nabisco and for Related itself, so the developer is starting the property's next life with none of the compromises of a retrofitted office asset.

The 2029 delivery date matters as much as the tenant's name. General Atlantic is not stepping into a recently emptied tower and taking space at a discount; it is committing years before completion to a building that is still under construction. That makes the transaction a forward commitment on future trophy supply rather than a leasing event inside a stressed asset, and Related, led by CEO Jeff Blau, holds a $100 billion portfolio of assets owned or under development, including Hudson Yards, a track record that suggests it can carry that schedule.

The 150,000-square-foot commitment shifts the underwriting from spec to credit-tenant, as PWD's prior coverage of the tower noted. Related now has a single named institutional credit on a 53-story building that will not deliver for years, and the leases that follow will be measured against that marker rather than against the distressed rents in the rest of Midtown. A single pre-lease does not tighten today's vacancy picture, but it does give Related a negotiating position no legacy landlord has: no vacant floors to carry and no reason to discount before delivery. The office market's clearing price will therefore come from the other side of the stack, the older buildings without Central Park views or 30,000-square-foot column-free floors, where landlords are the ones waiting on tenants. The 2029 opening at 625 Madison will arrive long before that segment has cleared.
