Executive Summary: Office leasing just posted its best quarter in years. CBRE reports leasing activity up 16% YoY in Q2 2026, prime vacancy down 40 bps to 12.3%, and Midtown Manhattan prime vacancy at 2.2%. JLL confirms a third consecutive quarter of positive net absorption. But the recovery is narrow — concentrated in prime/trophy assets — and rewards whichever landlord can act first on a renewal, expansion, or blend-and-extend. The bottleneck isn't demand; it's whether an asset manager can answer, in minutes, exactly what's in every lease across a portfolio.
CBRE's Q2 2026 report puts U.S. office leasing activity at 62.4 million sq ft, up 16% YoY, with trailing 12-month volume up 4% to 243 million sq ft — CBRE expects full-year leasing to surpass 2022, the strongest year on record. Vacancy fell 30 bps to 18.3%, the sharpest quarterly decline since 2015. Prime vacancy dropped 40 bps to 12.3%; Midtown Manhattan prime space sits at 2.2% vacancy, effectively sold out. JLL shows net absorption positive for a third straight quarter, with 3.5 million sq ft of quarterly occupancy gains. This is a flight-to-quality land grab in the top decile of the market, not a broad recovery.
A rebound this concentrated turns every existing lease into a live negotiation. Tenants with expansion rights are exercising them before competitors grab adjacent space. Landlords who can't immediately confirm renewal notice deadlines, escalation schedules, or exclusive-use restrictions lose leverage — or lose the deal to a sublease down the block. Most CRE portfolios still hold their most valuable leasing intelligence scattered across PDFs and disconnected systems, turning "what can this tenant do in the next 18 months" into days of manual review during a cycle where days decide who signs.
A few numbers put the stakes in context:
None of that AI investment matters if the lease terms it reasons over are wrong or buried. AI for CRE is only as valuable as the data feeding it.
Prophia customers lean on lease abstraction pairing AI extraction with human validation across an entire portfolio, so a renewal-rights question is a lookup, not a research project. Prophia represents 600M+ sq ft of CRE and has surfaced millions in lease discrepancies manual review missed. See Customers.
The gap between prime and secondary office assets will widen before it narrows, and the landlords who close it will treat lease data as operating infrastructure, not paperwork. That's already visible in the 2.2% number out of Midtown. The rebound is here — the question is which portfolios actually know what they're sitting on.
