In one sentence. Primary-market data-centre vacancy in North America sat at 1.4% at midyear 2026, essentially unchanged from year-end 2025 despite supply growing 33.7% year over year, because net absorption of 1,456 MW grew almost as fast.

Why it matters

This is the only part of commercial real estate where a landlord has unambiguous pricing power in 2026, and it is absorbing the capital, the crews and the electrical equipment that would otherwise go to industrial, office and residential construction. Any capital-allocation or contractor-capacity decision in this sector now has to be made relative to what data centres are doing, not independently of it.

What is happening

Primary-market data-centre vacancy in North America sat at 1.4% at midyear 2026, essentially unchanged from year-end 2025 despite supply growing 33.7% year over year, because net absorption of 1,456 MW grew almost as fast. Northern Virginia vacancy was 0.24% and Hillsboro 0.21%. Under-construction capacity in primary markets reached 7,481 MW, up 24.8%, and construction starts tracked by ConstructConnect hit $84.1bn year to date through July, roughly three times the prior year across 136 projects. Every other major US property type is either oversupplied, distressed or flat.

First observable signal. Data-centre vacancy first fell below 3% in primary US markets during 2023 as hyperscaler AI capex began landing in leasing; the crossing below 2% occurred during 2024-25 and has persisted through two subsequent reporting periods.

Evidence

Where sources disagree

• Data-centre capacity under construction in North America, mid-2026 — CBRE: 7,481 MW in primary markets vs JLL: more than 66 GW across North America. Likely reason: Definitional scope, not error. CBRE counts capacity physically under construction in its defined primary colocation markets; JLL counts a far broader universe including frontier markets, where it says 77% of the capacity sits, and earlier-stage or announced capacity. The roughly ninefold gap is the single best available measure of how much of the headline pipeline is contracted versus merely announced, and it should be reported as a range, never as a point estimate.
• Data-centre vacancy rate — CBRE: 1.4% primary markets vs JLL: 1% for the third consecutive year. Likely reason: Different market definitions and inventory bases. Both agree the market is functionally full; the 40bp gap is immaterial to the conclusion but illustrates that there is no authoritative vacancy figure for this asset class.

Companies. Digital Realty, Equinix, QTS (Blackstone), Vantage Data Centers, CyrusOne, Aligned Data Centers, Switch, STACK Infrastructure, Related Digital
Products. Wholesale colocation, Hyperscale build-to-suit, Powered shell, Retail colocation
Funding. Development capital is arriving as debt rather than equity: approximately $27.8bn of data-centre high-yield bond issuance across 12 offerings in H1 2026, $4.9bn of single-asset CMBS (9% of all SASB CMBS issuance), a $16bn Related Digital/Blackstone construction financing and a $5.7bn Meridian Arc financing priced at a 6.25% yield.

Impact

Industry. Beneficiaries: Data-centre REITs and developers, Landowners near transmission capacity, Electrical contractors and switchgear suppliers, Utilities with available interconnection. Losers: Industrial and manufacturing developers competing for the same crews and equipment, Ratepayers in constrained markets, Municipalities absorbing infrastructure cost without commensurate employment.
Consumer. Directly measurable and exceptional: 80.4% of all capacity under construction was preleased at H1 2026, up from 74.3% a year earlier, leaving under 1,500 MW available across primary markets - roughly six months of supply at the current absorption rate.
Regulatory. Rising and now binding in specific jurisdictions. New York imposed a one-year pause on state environmental permitting for projects requiring 50 MW or more in July 2026; Hillsboro, Oregon adopted a temporary land-use moratorium; Oregon HB 4084 restricted enterprise-zone property-tax eligibility; Arizona enacted a three-year pause on new data-centre sales-tax exemptions.
Geography. US, CA, EU, APAC

Risks and counter-forces

• Concentration: a small number of hyperscale tenants underwrite most of the preleasing, so counterparty risk is highly correlated
• Preleased does not mean delivered - power and equipment lead times can push deliveries past lease commencement dates
• Almost no equity transaction evidence exists to validate the valuations being lent against

Counter-trends. Municipal moratoria and local opposition constraining new sites, Power interconnection queues capping deliverable capacity regardless of land availability, A hyperscaler capex retrenchment, which would convert today's preleasing backlog into tomorrow's vacancy
