1 Madison Avenue has reached full occupancy after Harvey AI signed for the last available space, marking the completion of a multi‑tenant leasing push at the Midtown South tower.

The building’s repositioning has already attracted major names: anchor tenants include Franklin Templeton and Coinbase, among others, a lineup that helped rebrand the property as a premium office asset.

Owners are moving into a roughly $1.7 billion refinancing tied to the redevelopment, a financing step tied to the building’s new, fully leased status. Details on lenders and pricing were not disclosed in the reporting available.

The transaction and refinancing underscore a trend seen in recent New York leasing: demand concentrating in a relatively small set of highly upgraded, well‑located buildings that can command tenants seeking modern space and amenities.

What remains unclear is how much this single building will move broader Midtown South vacancy and rent metrics. Still, 1 Madison’s outcome is one more data point suggesting selective strength at the top end of the market rather than a broad recovery across all office stock.
