Market intelligence / Q1 2026

Compare the four largest U.S. colocation markets.

Northern Virginia, Atlanta, Dallas-Fort Worth, and Chicago hold roughly 7.8 GW of combined inventory. Each has deep infrastructure, tight capacity, and a different answer to the power, timing, network, and cost question.

The market shortlist

Start with business fit, then verify deployable capacity.

Published inventory shows market scale. It does not tell you whether the right power block, density, network ecosystem, and delivery date exist for your deployment.

No. 1 U.S. market
Northern Virginia

Ashburn and Data Center Alley

4,182 MWinventory
0.3%vacancy
10.8 MWavailable

The deepest ecosystem and tightest vacancy. Strongest when interconnection density and East Coast cloud access justify the pricing and capacity competition.

Dallas-Fort Worth

1,249 MWinventory
1.8%vacancy
43.7%annual growth

The fastest-growing top-four market, with central geography and a huge construction pipeline. Power interconnection and preleasing still shape real delivery options.

How to choose the right market

The right market is the one that meets the workload's latency, connectivity, risk, staffing, compliance, and budget requirements with a credible delivery path. Market rank alone should not decide it.

  1. Map users, applications, cloud regions, partners, and network dependencies.
  2. Define required power, rack density, cooling, and growth by date.
  3. Set disaster-recovery distance, climate, utility, and operational risk requirements.
  4. Compare existing capacity separately from planned or utility-dependent capacity.
  5. Normalize facility, network, migration, support, escalator, and renewal costs.
  6. Run at least two markets in parallel when the delivery date or power block is critical.
The practical rule

A second market is not only a fallback. It creates leverage, exposes hidden requirements, and shows the real cost of choosing ecosystem depth, geographic proximity, or faster delivery.

Shop by deployment

Move from market research to a qualified requirement.

GPU and high-density

10 to 100+ kW racks, liquid cooling and AI cluster readiness.

Private cages

Secure four to 20-rack footprints with expansion planning.

Wholesale capacity

Private suites and power blocks from 250 kW to 5 MW.

RFP checklist

An ungated template for a comparable provider response.

Build a verified shortlist

Compare facilities across markets, not marketing claims.

A scout can turn one requirement into a normalized search across the markets that can realistically serve it.
