Data centers have become one of the fastest-growing parts of commercial real estate, but square footage no longer tells you much about the market.

Power does.

A developer can find hundreds of acres, secure zoning, and design a large campus, yet the project may still wait years for enough electricity to operate. At the same time, tenants continue to lease capacity before construction finishes, pushing vacancy close to zero in several established markets.

The data center market 2026 reflects both conditions. Demand remains strong, new supply continues to grow, and investors can still finance large projects. However, access to power, transmission capacity, development timelines, and local regulation increasingly determine where projects can move forward.

That changes the way you analyze the property. With an office or industrial building, you might begin with square feet, rent, occupancy, and comparable sales. For a data center, megawatts, power delivery dates, tenant credit, cooling requirements, fiber connectivity, and the cost of bringing the site online can matter just as much as the land and building.

Data Center Market 2026 at a Glance

Market measure	Latest reading	What it measures
Vacancy in four largest U.S. markets	Near historic lows in Q1 2026	Available operating capacity
Northern Virginia vacancy	0.3%	Q1 2026
Atlanta vacancy	1.0%	Q1 2026
Dallas-Fort Worth vacancy	1.8%	Q1 2026
Chicago vacancy	2.2%	Q1 2026
North American vacancy	About 1%	Midyear 2026
North American capacity under construction	More than 66 GW	Midyear 2026
Share of construction in frontier markets	77%	Midyear 2026
U.S. data center electricity use, 2030 reference case	649 TWh	LBNL estimate
Share of total U.S. electricity, 2030 reference case	11.8%	LBNL estimate
Data center securitization volume	$17 billion, H1 2026	SASB/CMBS + ABS

These measures describe different parts of the business. Vacancy and rent show conditions in operating facilities, while megawatts under construction measure future capacity. Electricity forecasts tell you how much power the sector may require, not how much real estate will actually reach completion.

Vacancy Is Extremely Low Despite Rapid Construction

The CBRE Global Data Center Trends 2026 report shows just how tight the major U.S. markets became during the first quarter. Inventory across Northern Virginia, Atlanta, Dallas-Fort Worth, and Chicago increased 33% from a year earlier, yet vacancy still fell to record or near-record lows.

That combination deserves attention.

Normally, a large increase in supply gives tenants more choices and puts pressure on rents. In the current data center market, new capacity has arrived while tenants have continued to absorb it.

Across those four markets, Q1 net absorption reached 2,236.2 MW, up 34% from a year earlier. Northern Virginia alone accounted for 1,148.3 MW.

Available capacity also remained scarce. Northern Virginia had only 10.8 MW available in Q1, Chicago had 19.8 MW, and Atlanta had 14.5 MW. Dallas-Fort Worth added almost 380 MW of inventory over the year, but available supply increased by only 1.4 MW.

In other words, developers have added capacity without creating much slack in the market.

Power Demand Is Changing Data Center Real Estate

A data center is both a real estate asset and a very large electrical load.

The Lawrence Berkeley National Laboratory 2025 update to the U.S. Data Center Energy Usage Report estimates that data centers could consume 649 terawatt-hours of electricity in 2030 under its reference case. That would equal approximately 11.8% of total U.S. electricity consumption. The report gives a wider range of 521 to 843 TWh, or 9.5% to 15.3% of U.S. electricity use, depending on equipment installations, AI-chip use, utilization, and other assumptions.

Those estimates help explain why utilities and grid operators now play such a large role in site selection.

The Energy Information Administration looks at the issue from another angle. Its Annual Energy Outlook 2026 analysis of server electricity use estimates that data center servers alone accounted for about 7% of commercial-sector electricity consumption in 2025. EIA expects server electricity use to keep growing even as computing equipment becomes more efficient in some scenarios.

For property investors, the practical question is no longer simply whether electricity is nearby. You need to know how much firm power the utility can deliver, when it can deliver it, what upgrades the project requires, and who pays for them.

The Major U.S. Data Center Markets

Four markets stood at the top of CBRE’s U.S. inventory rankings in Q1 2026: Northern Virginia, Atlanta, Dallas-Fort Worth, and Chicago.

Market	Q1 2026 inventory	Q1 2026 vacancy	Notable trend
Northern Virginia	4,182.0 MW	0.3%	Largest global market
Atlanta	1,465.2 MW	1.0%	Tight vacancy despite new supply
Dallas-Fort Worth	1,249.4 MW	1.8%	Inventory +43.7% YoY
Chicago	910.6 MW	2.2%	Inventory +37.7% YoY

Each market has strong demand, but the reasons developers choose them—and the constraints they face—are different.

Northern Virginia: Still the Largest Data Center Market

Northern Virginia remains the country’s dominant data center cluster.

Wholesale inventory reached 4,182 MW in Q1 2026, an increase of 1,135.9 MW from the previous year. Despite that huge addition, vacancy fell from 0.8% to just 0.3%.

Net absorption reached 1,148.3 MW, the strongest result CBRE has recorded for a market since it began its current global report series.

Electricity data confirm how much data centers have changed the region. The U.S. Energy Information Administration reports that Virginia’s commercial electricity sales increased by nearly 30 million MWh between 2019 and 2025, with data center concentration driving much of that increase. PJM expects the Dominion zone to record the largest absolute increase in summer peak electricity demand between 2026 and 2030, largely because of data center growth.

However, Northern Virginia’s size now creates its own development problems.

Large sites have become harder to find in established locations such as Loudoun and Prince William counties. CBRE also reports that zoning, entitlement, and power constraints are pushing some developers farther south along I-95 and toward Richmond.

Rental pricing shows how little capacity remains. CBRE reported Q1 asking rents of approximately $190 to $235 per kW per month for requirements in the 250-to-500-kW range.

Northern Virginia still offers unmatched scale and connectivity, but a developer now has to solve site availability and power delivery before assuming the market’s strong demand will translate into a viable project.

Dallas-Fort Worth: Rapid Growth Meets a New Power Review

Dallas-Fort Worth moved up to become the nation’s third-largest colocation market during Q1.

Inventory increased 43.7% year over year to 1,249.4 MW. Meanwhile, 716.7 MW was under construction, and tenants had already preleased 88% of that capacity.

Those figures show strong demand. Still, the Texas development environment changed materially in August.

On August 3, 2026, the Office of the Texas Governor ordered a comprehensive audit of data centers seeking ERCOT interconnection. The state directed the Public Utility Commission of Texas and ERCOT to complete the review before projects move forward through the interconnection process. According to the governor’s office, ERCOT was considering more than 474 GW of connection requests, with data centers accounting for approximately 90% of new power requests.

The audit asks projects to document their expected electricity use, on-site generation, water requirements, cooling technology, incentives, and measures to reduce effects on surrounding communities.

EIA responded to the change in its August 2026 Short-Term Energy Outlook. The agency reduced its forecast for 2027 Texas electricity-load growth from 14% to 6%, citing the state’s review of new data center development.

That does not erase Dallas-Fort Worth’s existing demand. However, it adds another item to the development checklist: a project now needs to satisfy a changing state interconnection process as well as local zoning and utility requirements.

Atlanta: Supply Has Grown, but Tenants Keep Taking It

Atlanta has become one of the largest U.S. data center markets.

Inventory reached 1,465.2 MW in Q1 2026, up 14.5% from a year earlier. Even with that increase, vacancy dropped from 3.6% to 1.0%.

Available capacity fell sharply as well, from 45.7 MW to just 14.5 MW.

Atlanta offers several features that support continued development: fiber connectivity, available land in outer submarkets, and planned additions to Georgia’s power-generation system. At the same time, large-load customers face closer scrutiny over the infrastructure costs required to serve them.

For a developer, Atlanta shows why a market’s capacity pipeline and utility rules need to be studied together. Strong tenant demand can support a project, but the power agreement and development schedule still determine when the asset can begin producing revenue.

Chicago: Strong Demand, Long Power Timelines

Chicago reached 910.6 MW of wholesale inventory in Q1, up 37.7% from a year earlier.

Vacancy fell to 2.2%, while available inventory dropped to 19.8 MW. Chicago also recorded some of the highest quoted rents among the four major markets, with CBRE reporting approximately $200 to $230 per kW per month for 250-to-500-kW requirements.

Power delivery, however, presents a major hurdle. CBRE reports that ComEd timelines for some projects stretch to 2032 or later.

Developers have responded by looking farther west into submarkets such as Elk Grove, Northlake, and Hoffman Estates, where power and fiber conditions may support additional growth.

Chicago’s situation is a reminder that current vacancy and future development capacity can tell very different stories. A market may have almost no available space today while projects proposed now face years of waiting for power.

Development Is Moving Beyond the Established Markets

The next stage of data center growth is not limited to the four largest clusters.

JLL’s North America Data Center Report Midyear 2026 estimates that more than 66 GW of capacity is under construction across North America. More strikingly, 77% of that capacity is in frontier markets rather than the established hubs.

West Texas has attracted some of the largest projects, while Ohio, Louisiana, Indiana, and the Carolinas have also gained development.

Why move outside the major markets?

In many cases, developers can find larger sites and pursue power arrangements that would take longer or cost more in Northern Virginia, Chicago, or another established cluster. Land cost matters, but it often ranks behind power availability when a project requires hundreds of megawatts.

Tennessee provides another example. CBRE reports that data center demand accounted for 18% of the state’s industrial electricity load in 2025 and could double by 2030, supported by more than 6 GW of new generation capacity.

That shift changes the real estate map. A location that barely registered as a data center market several years ago can become viable if developers secure large tracts, transmission access, fiber, and enough generation.

Power Interconnection Has Become Part of Development Risk

A data center developer cannot treat electricity service as a routine utility connection.

In June 2026, the Federal Energy Regulatory Commission directed all six regional grid operators under its jurisdiction to review or reform their rules for large-load interconnections. The action covers data centers as well as manufacturing facilities and other large electricity users.

FERC’s action shows how quickly large-load growth has moved from a local utility issue into regional grid planning.

For an investor, the consequences are practical. Before committing to a site, you need to understand:

• Available utility capacity
• Required transmission upgrades
• Interconnection-study timelines
• Deposits and financial guarantees
• Cost responsibility for upgrades
• Expected energization date
• Backup generation requirements
• On-site generation options
• Cooling system and water requirements
• Risks if the tenant or project does not proceed

A land contract may allow enough time for zoning and environmental work yet still fail to cover the period required to obtain firm power.

Rent Is Increasing, but Capacity Matters More Than Square Feet

Traditional CRE investors often compare rent per square foot.

Data center leasing works differently.

Operators commonly quote capacity in dollars per kilowatt per month because the amount of power available to the tenant is central to the lease. A building with more physical space does not necessarily produce more revenue if the site cannot support additional electrical load.

CBRE reported Q1 pricing of about $190 to $235 per kW per month in Northern Virginia and $200 to $230 in Chicago for smaller wholesale requirements. Across the four major U.S. markets, aggregate average asking rents increased by single digits from a year earlier.

Chicago recorded the largest year-over-year increase at 14.7%, while Atlanta rose 2%. Dallas-Fort Worth asking rents were essentially unchanged.

Those figures should not be turned into a national rent assumption. Contract size, power density, lease structure, redundancy, market, tenant credit, and facility specifications can all change pricing.

Financing Remains Available for Data Center Development

Unlike some CRE sectors, data centers continue to attract substantial debt capital.

JLL reported strong project-finance liquidity at midyear 2026. Construction loans for top-tier hyperscale tenants were pricing at credit spreads in the low-200-basis-point range, with leverage reaching as high as 85% loan-to-cost on some projects.

Deals involving tenants without investment-grade credit receive more scrutiny. JLL reported spreads roughly 200 to 300 basis points wider and leverage generally around 70% to 80% loan-to-cost for those transactions.

Capital markets activity also increased. Data center SASB/CMBS and ABS issuance reached $17 billion during the first half of 2026, up 29% from the prior year.

Tenant quality therefore affects far more than leasing risk. It can influence construction leverage, debt pricing, permanent financing, and ultimately the amount an investor can pay for the site.

Land Alone Does Not Make a Data Center Site

Large data center campuses can require hundreds of acres, but acreage only solves one part of the development problem.

Before treating an industrial parcel as data center land, check:

• Firm power capacity
• Transmission and substation access
• Expected energization date
• Fiber routes and carrier diversity
• Water availability where the cooling system requires it
• Zoning and permitted use
• Noise limits and setbacks
• Backup-generation rules
• Flood and environmental risk
• Site grading and geotechnical conditions
• Local incentives
• Property-tax treatment
• Community opposition
• Construction labor availability

Power should come early in that review.

A large parcel with attractive zoning can have little data center value if the utility cannot supply enough electricity for years. Conversely, land farther from an established cluster may command attention if it offers a realistic path to several hundred megawatts.

Preleasing Changes the Development Math

Data center tenants often commit to capacity long before construction finishes.

Dallas-Fort Worth illustrates the scale of that practice: tenants had already preleased 88% of the market’s 716.7 MW under construction in Q1.

Preleasing can reduce lease-up risk and make financing easier, especially when the tenant has strong credit. However, the lease does not remove construction, interconnection, or delivery risk.

A delayed energization date can postpone rent even when the space has a committed tenant. Construction costs can also change while a developer waits for utility work.

As a result, investors need to pay close attention to lease commencement conditions, delivery obligations, extension rights, termination provisions, and responsibility for utility delays.

What to Watch Through the Rest of 2026

Several measures will show whether the current data center market 2026 conditions continue.

Vacancy matters, but watch available megawatts as well. A market can report a low vacancy rate while the remaining capacity is too fragmented for a large tenant.

Next, follow preleasing and construction. A large pipeline means less if most projects lack firm power dates.

Electricity policy deserves just as much attention. Texas has already shown how quickly a state can change the near-term development process when connection requests exceed what the grid can reasonably accommodate.

Financing also needs regular review. Strong debt liquidity supports development today, but lenders still differentiate sharply between top-tier hyperscalers and weaker tenant credit.

For individual projects, keep track of:

• Existing inventory
• Available MW
• Vacancy
• Net absorption
• Capacity under construction
• Percentage preleased
• Asking rent per kW
• Power-delivery timelines
• Transmission upgrades
• Utility deposits and guarantees
• Tenant credit
• Construction costs
• Cooling and water requirements
• Local zoning
• Tax incentives
• Financing terms
• Lease commencement requirements

These figures give you a much better picture than square footage alone.

What the 2026 Data Center Market Shows So Far

Demand remains strong in the largest U.S. data center markets.

Northern Virginia added more than a gigawatt of inventory in a year and still finished Q1 with only 0.3% vacancy. Dallas-Fort Worth expanded inventory by almost 44%, yet tenants had already committed to most of the capacity under construction. Atlanta and Chicago also added supply while vacancy moved lower.

Meanwhile, development is spreading into markets that offer more land and, in some cases, a better path to power. JLL now places most North American capacity under construction outside the established hubs.

The main constraint is becoming easier to identify. Electricity demand from data centers is growing fast enough to affect utility planning, state policy, and federal regulation. LBNL’s 2030 estimates show how large the sector’s share of U.S. electricity consumption could become, while FERC’s 2026 actions show that grid operators now need new procedures for connecting very large loads.

For a CRE investor, that changes the order of the questions.

Don’t begin with, “How many acres can I buy?”

Start with: How much power can this site get, when can it get it, and who is willing to lease the capacity once it arrives?

After that, the land, building cost, rent, financing, and return assumptions can be tested against a project that has a realistic chance of getting built.
