Record-Breaking Rents and Rapid Deal Cycles

The urgency of AI growth is compressing the traditional real estate timeline. Landlords report that AI startups often tour and sign documents within two weeks—a process that typically takes months. This demand is concentrated at the very top of the market:

Nscale: The Nvidia-backed infrastructure firm signed the second-most-expensive lease in NYC history, paying $320 per SF at SL Green’s One Vanderbilt.

Harvey AI: The legal AI startup doubled its footprint to 185K SF at One Madison Avenue following an $11 billion valuation.

Leasing Size: The average deal size for AI companies has more than doubled, jumping from 16,600 SF to 34,500 SF.
