AI Tenants Are Rewriting the Rules of Office Leasing
Something is happening in Manhattan’s office market that is unlike anything most veterans of the industry have seen before. A new class of tenant has arrived — well-capitalized, urgency-driven, and completely uninterested in the slow, deliberate leasing process that defined the industry for decades.
As covered in The Real Deal’s June 2026 issue, AI startups are snapping up office space at a pace that has stunned landlords and advisors alike — and in doing so, rewriting nearly every convention of how leasing is supposed to work.
Speed Is Now the Primary Metric
The most visible shift is pace. Deals that once took months now happen in fewer than 30 days, as the office becomes the manifestation of sky-high aspirations, hiring goals, and funding. In one documented case, an AI marketing firm submitted a letter of intent on an 18,800 square foot Chelsea space less than 36 hours after the first tour.
Brandon Charnas has observed this urgency firsthand across Current Real Estate Advisors’ growing roster of AI and technology clients. The calculation these companies are making is straightforward: losing the right space to a competitor is a more expensive mistake than moving quickly on imperfect information.
“The priority for a lot of these firms is speed and certainty — not chasing every last dollar and penny-pinching,” Adam Henick, co-founder of Current Real Estate Advisors, noted in The Real Deal. “They’d rather lock down the right space immediately than risk losing it, negotiating over what someone else may consider minor economics.”
The Office Is No Longer Just an Expense Line
What separates AI tenants from prior generations of office occupiers isn’t just their pace — it’s their frame of reference. For these companies, the office is a recruiting tool, a culture signal, and often a direct physical expression of where the company is heading.
In the first quarter of 2026, AI tenants accounted for more than a third of the tech sector’s demand in Manhattan, with 670,000 square feet leased — a sharp jump from their 12 percent share in 2025. These companies are competing for talent as aggressively as they are competing for market share, and the office has become a front line in that competition.
That calculus is forcing everyone involved in a transaction to operate differently. Landlords are being forced to size up AI tenants on an accelerated timeline, reviewing financials and learning about their businesses far faster than in a typical leasing process. Advisors are clearing schedules and moving in real time. The traditional “getting to know each other” phase that once defined early-stage lease negotiations has essentially disappeared.
What This Means for Landlords and Tenants Alike
The rise of AI as a dominant leasing force has created both opportunity and exposure depending on which side of the market you’re on — and how prepared you are.
For landlords, the upside is significant. AI’s footprint in San Francisco alone is predicted to double by 2030 to 14 million square feet, per JLL projections. The companies that sign shorter leases today are often the ones that triple their footprint in 18 months. Getting in early, even on flexible terms, can position a building for a transformative long-term tenant.
For tenants, the message is equally clear. The companies that hesitate — that wait for more certainty, more options, or a slightly better economic package — are consistently the ones losing the spaces they wanted to the companies that moved faster.
Brandon Charnas works with both sides of this dynamic at Current Real Estate Advisors. The AI leasing moment is real, it is accelerating, and the professionals who understand its logic are the ones structuring the transactions that will define this market over the next decade.
