Question
How much data center capacity is still available in North American primary markets?
Short answer
Under 1,500 MW across all primary markets as of H1 2026 — roughly six months of demand at the current absorption rate. Primary-market vacancy is 1.4% and 80.4% of capacity under construction is already preleased.
Market-wide position
The figures below are the market-wide findings published in CBRE's H1 2026 report. They describe colocation and wholesale supply in primary markets, not utility load availability for a self-built campus.
| Indicator | Value | Note |
|---|---|---|
| Primary market vacancy rate | 1.4% | Record low across primary markets. |
| Share of under-construction capacity preleased | 80.4% | Capacity is committed before delivery. |
| Future capacity available, all primary markets | Under 1,500 MW | Roughly six months of demand at the current absorption rate. |
| Investor survey selection, CBRE 2026 | Dallas-Fort Worth, 78% | Northern Virginia second at 72%. |

What this means for a site search
With vacancy near zero and most construction preleased, a requirement that cannot be met from existing leased supply depends on new utility load service. That is set by the serving utility's large-load tariff and study queue, which this dataset does not measure.
Metro-level power indicators — industrial retail price, SAIDI and SAIFI, grid market — are shown in the Power & Energy section of each scorecard.
