Two AI Companies Ink Full-Floor Deals at 61 West 23rd Street

Via Commercial Observer · September 21, 2026

Why this matters

Office continues to trade in two distinct markets: trophy assets in walkable submarkets that are leasing at or near record rents, and commodity Class B and C buildings where the basis is still resetting. Underwriting on the latter has moved toward replacement-cost-minus, with credit underwriting now leaning on tenant covenant and remaining lease term rather than mark-to-market expectations. New York continues to bifurcate sharply: trophy office leasing at record rents, commodity Class B in conversion discussions or court-supervised processes. Rent-stabilized multifamily remains supply-constrained and tightly held. For LP-positioned capital, the read-through is that the bifurcation is now a structural feature of the sector, not a cycle to wait out.
