Investors can approach the data center boom through companies that own and operate facilities, supply computing technology, or provide electricity and grid infrastructure. But rising demand is not a guarantee that announced projects will be built, earn expected returns, or make every related investment attractive. The key is to compare each business’s role in the buildout with its power access, project execution, financing needs, and valuation.
What is driving data center investment?
Artificial intelligence is accelerating demand for computing capacity, but data centers also support cloud computing and other digital services. More computing requires more facilities, servers, networking equipment, and reliable electricity. Power is both an essential input to growth and a constraint on how quickly new capacity can come online.
The International Energy Agency (IEA) reported in its 2025 Energy and AI executive summary that global investment in data centers nearly doubled from 2022 and reached half a trillion dollars in 2024. The same report estimated that data centers used 415 terawatt-hours (TWh) of electricity globally in 2024, about 1.5% of world electricity consumption.
The IEA’s 2026 Key Questions on Energy and AI update estimates that global data center electricity demand grew 17% in 2025, to 485 TWh. It projects demand could reach 950 TWh in 2030, roughly 3% of global electricity demand; AI-focused data center consumption grew 50% in 2025. These are estimates and projections, not measurements of future outcomes. The IEA also says buildout pace is sensitive to expected returns and macroeconomic and financing conditions.

What do the different investment and power forecasts mean?
These estimates have different geographies, methods, and forecast dates. They should not be blended into a single consensus number. In particular, investment spending is not the same measure as electricity consumption or power demand.
| Publisher and measure | Estimate | How to read it |
|---|---|---|
| IEA, global data center investment | Half a trillion dollars in 2024 | Reported in the IEA’s 2025 Energy and AI executive summary; global investment nearly doubled from 2022. |
| Federal Reserve researchers, U.S. data center investment | $370 billion annualized by 2026:Q2, mean estimate | A U.S.-specific project-level forecast, not the IEA’s global investment measure. |
| Federal Reserve researchers, U.S. data center investment | $360 billion to $930 billion in 2027 | A conditional range based on future project-plan flows of one-quarter to twice the 2024–2025 average pace. It is not a confidence interval; the researchers caution that forecasting at a turning point is potentially fraught. |
| IEA, global data center electricity consumption | 485 TWh in 2025; 950 TWh projected in 2030 | The IEA’s 2026 estimates and projection; electricity use, not investment spending. |
| Gartner, global data center electricity consumption | 447 TWh in 2025; 565 TWh forecast in 2026 | Gartner’s June 10, 2026 forecast. Its 2026 estimate differs from the IEA’s and should be treated as a separate forecast, not averaged with it. |
| Gartner, worldwide data center power demand | 132 gigawatts (GW) forecast in 2026 | A Gartner forecast of power demand, a different measure from annual electricity consumption. |
The range in the Federal Reserve researchers’ 2027 estimate illustrates how sensitive project-level forecasts are to assumptions about plans that have not yet become completed capacity. Gartner analyst Linglan Wang described power as a limiting factor for AI expansion: “Surging demand for compute-intensive AI workloads is driving unprecedented data center power growth, while AI capacity is now constrained by power availability, making data center power security the new battle ground for scaling and protecting margins in the global AI race.”
How can an investor get exposure to the data center economy?
Compare businesses by what they sell and which part of the buildout must succeed for them to benefit. These are analytical categories, not recommendations to buy particular securities.
| Exposure | What the business does | Questions to investigate |
|---|---|---|
| Data center property and digital infrastructure | Owns or operates facilities and sells access to data center capacity. | Are projects powered and completed? Is capacity occupied and revenue-producing? How concentrated are facilities in areas with constrained power or grid access? |
| Technology companies and equipment suppliers | Builds or rents computing capacity, or supplies technology used in data centers. | How much of the business depends on continued customer spending and utilization? Can it deliver the required equipment and capacity as planned? |
| Electricity and grid infrastructure | Provides generation, transmission, grid equipment, or related infrastructure needed to supply power. | Can new supply and grid connections arrive in time? What are the local market, fuel, policy, and project-financing exposures? |
Investors may encounter these businesses through individual company shares or funds, but a fund’s name alone does not establish its actual exposure. Check current holdings, concentration, fees, and whether the holdings are materially tied to data center growth. Direct or private infrastructure investments have different access, liquidity, and risk considerations from publicly traded securities; the reports cited here do not assess particular offerings.

For any route, examine whether growth is already reflected in the price. The IEA, Federal Reserve, EIA, and Gartner materials discussed here do not provide current company valuations, fund fees, or an assessment of individual investor suitability. Those questions require separate, current analysis.
Why can demand growth fail to become completed projects?
A project announcement is not operating capacity. The IEA’s 2026 analysis identifies electricity supply, grid connections, advanced chip manufacturing, and capital as potential bottlenecks. It also reports that high-bandwidth memory shortages were expected to persist through at least the end of 2027, as assessed in that report. Delays can defer revenue while costs continue; shortages or financing constraints can also change project economics.
Grid expansion moves on a longer timeline than many technology deployments. The IEA’s 2025 report estimated that around 20% of planned data center projects could be at risk of delay if grid risks are not addressed. It said transmission lines can take four to eight years to build in advanced economies and that wait times for critical grid components, including transformers and cables, had doubled over the prior three years. The report also found that 50% of U.S. data centers under development were in existing large clusters, increasing exposure to local bottlenecks.
Community opposition, affordability concerns, and environmental concerns can affect local approvals. For investors, the practical questions are whether a particular site can secure power and permits, when a connection is expected, whether customers have committed to capacity, and whether financing remains available through construction.

How could data center growth affect electricity prices?
Price impacts depend on location and on how quickly supply responds. In a March 12, 2026 analysis, the U.S. Energy Information Administration (EIA) modeled a high-demand scenario in which demand growth in regions with significant data center development was 50% above the February 2026 Short-Term Energy Outlook baseline in both 2026 and 2027. This was a scenario, not a forecast of guaranteed prices; EIA noted that results could differ from its later March outlook.
In that model, the 2027 wholesale electricity price in the Electric Reliability Council of Texas (ERCOT) region was $37 per megawatt-hour (MWh) above the February baseline. For other major covered hubs, the modeled average increase was $2.10/MWh above a $48/MWh baseline average. The much larger ERCOT response shows why a national demand story cannot establish a uniform local price outcome.
What energy sources may serve new data center demand?
Growth in data center electricity use does not imply that one energy source will supply it everywhere. The IEA’s 2025 supply analysis estimated that renewables provided about 27% of electricity physically consumed by data centers globally, natural gas 26%, nuclear 15%, and coal about 30%. These shares describe physical generation mix, not electricity that operators may claim through contractual procurement.
In its base case for 2024–2030, the IEA projects renewables generation will grow by an average of 22% annually and meet nearly half of data center demand growth. It also projects that natural gas and coal together will meet more than 40% of additional electricity demand through 2030. The mix varies by region: for the United States, the IEA expects gas to be the largest source of additional data center electricity through 2030, with renewables second, and projects low-emissions sources will exceed half of the U.S. supply mix by 2035 in its base case. Its expectation that nuclear, including small modular reactors, contributes more after 2030 is an outlook, not confirmation that projects will be completed.

A practical due-diligence checklist
- Identify the revenue link: Determine whether the company owns facilities, sells technology, builds or rents computing capacity, or supplies power and grid infrastructure.
- Test execution, not announcements: Look for evidence that projects can secure power, connections, equipment, customers, and financing on a workable timetable.
- Check geography: Assess local capacity, interconnection timelines, price exposure, and whether operations are concentrated in constrained hubs.
- Consider capital needs: Evaluate funding requirements, cost of capital, customer commitments, and sensitivity to weaker market sentiment.
- Review energy and policy exposure: Consider fuel availability, renewable procurement, grid investment, and the different timing of gas, renewables, and nuclear supply.
- Assess the investment itself: Check valuation, diversification, fees where relevant, liquidity, and fit with your financial circumstances. Sector growth alone cannot answer those questions.
