The numbers describe an overshoot, not a collapse. Construction starts have already fallen hard — from roughly 13 million square feet in 2022 to about 3.2 million in 2025 — as the pipeline corrects. But the space built during the boom is still working through the system, and tenants are in no hurry.

Demand is concentrated and selective. Boston-Cambridge and the San Francisco Bay Area absorbed roughly 58% of recent deliveries and about 70% of leasing demand. The strongest tenants now have options — and a growing pool of discounted sublease space — so they're negotiating, not chasing.

This is a textbook lesson in underwriting specialized product. Lab space is among the most expensive square footage to build and the hardest to repurpose. When demand for highly specific product is underwritten on a single cycle's absorption curve, the downside isn't a soft patch — it's structural vacancy that can't be cured by dropping the rent on a generic floor plan.

The repricing will arrive in sequence: concessions and sublease discounts first, then headline rents, then valuations. The marginal landlord — the one who financed a speculative lab build at peak basis — is the exposed party. The institutional owner with leased, well-located product in a primary cluster is relatively insulated.

It also exposes the danger of a national average. A single "life sciences vacancy" figure blends a demand-rich Cambridge with a glutted secondary market. The real intelligence is in the submarket and the building, not the sector label — and the spread between trophy and commodity lab space is about to widen the way it did in office.

The broader read connects to the rest of today's package. Life sciences overbuilt; retail (a decade of building almost nothing) is now the tightest it's been in 20 years; data centers can't build fast enough because power, not capital, is the wall. The common thread isn't rates — it's supply discipline. In 2026, the asset classes winning and losing are sorted almost entirely by who got the supply curve right.

Stakeholder lens. Developers: stress-test specialized product against a thin tenant universe before committing capital to non-repurposable fit-out. Lenders: watch lab construction loans underwritten in 2021–2022 — the collateral is harder to re-tenant than a comparable office. Investors: the discount is real, but distinguish discounted-trophy (a buying opportunity) from cheap-and-stranded (a value trap).
