CBRE Q1 2026: Northern Virginia at 0.3% Vacancy. Why France's Available Capacity Changes the Equation.
CBRE's Q1 2026 global data center report documents what the AI infrastructure market has been signalling for 18 months: powered, grid-connected capacity in the world's largest markets has effectively disappeared. The vacancy data is the clearest quantification yet of a market where demand permanently outpaces supply — and where the next wave of capital has no choice but to look at markets that still have room.
Northern Virginia: 0.3% vacancy — the world's largest data center market, effectively full
Atlanta: 1.0% vacancy
Dallas-Ft. Worth: 1.8% vacancy — 716.7 MW under construction, 88% already preleased
Chicago: 2.2% vacancy
Net absorption (top 4 North American markets): 2,236 MW in Q1 2026 — up 34% YoY
Inventory growth: +33% YoY across top 4 North American markets
The paradox: supply is growing at 33% per year and vacancy is still collapsing. Every MW built is spoken for before it opens.
WHAT 0.3% VACANCY ACTUALLY MEANS
Northern Virginia's 0.3% vacancy rate is not a market statistic. It is a market closure notice. At 0.3%, the available space consists of partial suites, non-standard configurations, or capacity that is technically unoccupied but subject to contractual reservation. For a developer or hyperscaler looking to deploy 50 MW or more, Northern Virginia is closed. The capacity does not exist in any timeframe that matters for 2026–2028 deployment targets.
Dallas-Ft. Worth illustrates the pipeline problem equally well. 716.7 MW is under construction — a significant supply addition. But 88% of it is already preleased. That 716.7 MW will be absorbed before the first server is installed. The market is pre-selling capacity that does not yet exist, which means the vacancy rate in Dallas will remain near zero even as construction activity peaks.
The absorption numbers confirm the magnitude: 2,236 MW absorbed across the top 4 North American markets in a single quarter — up 34% year-on-year. That is the equivalent of adding a new Frankfurt-scale data center market every three months, and vacancy is still tightening.
THE PRICING SIGNAL — SCARCITY IN NUMBERS
Dallas-Ft. Worth: $115–160/kW-month — lowest major market
São Paulo: $110–170/kW-month
Amsterdam: $145–170/kW-month
Atlanta: $145–175/kW-month
Paris: $150–185/kW-month — competitive vs US majors
Northern Virginia: $170–215/kW-month
Frankfurt: $235–265/kW-month
Tokyo: $165–350/kW-month
Singapore: $310–450/kW-month
Annualised: $200/kW-month = $2.4M per MW per year
New-build capex: ~$10–12M per MW before land, power, delays, financing
Implied payback: 2–5 years gross rent/capex — which explains why scarcity drives lease rates higher
Paris at $150–185/kW-month is positioned competitively against Northern Virginia ($170–215) and well below Frankfurt ($235–265). This is not a secondary market pricing discount — it is a reflection of available capacity in a market that has not yet been fully absorbed. Paris has room. Northern Virginia does not.
THE EUROPEAN PICTURE — VACANCY AND OPPORTUNITY
Overall Europe vacancy: 7.3% — vs North America 0.9%
Europe net absorption Q1 2026: 572 MW
Emerging European market: Lisbon, Portugal
By city (estimated from CBRE data):
Frankfurt: ~4% vacancy — tightening rapidly
Paris: ~6% vacancy — available capacity with competitive pricing
London: ~7% vacancy — constrained by grid and planning
Amsterdam: ~8% vacancy — moratorium limiting new supply
Key insight: Europe's 7.3% overall vacancy is not uniform. Frankfurt and Paris are tightening. Amsterdam is constrained by moratorium, not demand. The available capacity is concentrated in markets with open grid processes — which in Western Europe means France above all others.
Europe's higher vacancy rate compared to North America reflects a different market structure, not lower demand. European markets are constrained by grid moratoria (Ireland, Netherlands) and planning complexity (Germany) rather than by lack of demand. The 572 MW absorbed in Europe in Q1 2026 represents genuine demand that could be higher if supply were available.
WHY FRANCE IS THE AVAILABLE-CAPACITY PLAY
The CBRE data identifies Paris as a major European market with available capacity and competitive pricing. But Paris is not the most important French opportunity for new AI data center development. It is the established market. The growth opportunity is in the broader France geography — specifically the brownfield HTB corridor in Hauts-de-France that Morgan Stanley named as a key secondary market driver in their June 15, 2026 report.
North of France combines three things that no other available-capacity market in Europe or North America currently offers simultaneously: open RTE grid connections at 12–24 months, nuclear baseload at €50–70/MWh and 51 gCO2e/kWh, and brownfield industrial sites with existing HV infrastructure that compress deployment to 18 months. The CBRE data shows where the capacity vacuum exists. RTE's fast-track programme shows where it can be filled fastest.
Northern Virginia vacancy: 0.3% — closed for new large loads
France (North) vacancy: Available — 4,800 MW RTE fast-track identified
Northern Virginia new supply: preleased before construction
France brownfield HTB: 18 months to first power — not yet fully allocated
Northern Virginia pricing: $170–215/kW-month
France colocation pricing (Paris): $150–185/kW-month
France grid connection cost (brownfield HTB): €2–20M total
France transformer: Efacec/Pauwels 20–32 months — ordered month 1
Microsoft Project Kilby cost to bypass ERCOT: $7 billion
Cost to connect brownfield HTB in France: €2–20 million
THE SIMPLE READ — AND WHAT IT MEANS FOR CAPITAL ALLOCATION
CBRE's Q1 2026 report tells a simple story: the market is adding capacity quickly, but usable, powered, AI-ready capacity is still scarce. That scarcity keeps rents firm and pushes growth into frontier markets with land, power, and faster interconnection.
For developers and infrastructure funds, the CBRE data converts the France grid thesis from a narrative into a market position. Northern Virginia at 0.3% vacancy is not a buying opportunity — it is a signal to look elsewhere. Paris at $150–185/kW-month with available capacity is an entry point. North of France with 4,800 MW of RTE fast-track capacity and brownfield sites at 18 months is a development opportunity that the CBRE data confirms is rational, timely, and increasingly scarce as the same capital that found Northern Virginia too late looks for the next deployable market.
NORTHERN VIRGINIA IS FULL. FRANCE IS NOT.
GridReadiness identifies brownfield HTB sites in France with existing grid connections, validates transformer procurement, and delivers a written Go/No-Go in 72 hours. The capacity CBRE is pointing toward is finite and depleting.
