Data centers dominate the latest US construction economic report: Structural divergence under the wave of AI infrastructure

Data Centers: The Only Growth Engine in the Construction Economy

The U.S. construction economic report for May 2026 presents a paradoxical picture: overall indicators are improving, but nearly all the bright spots are concentrated in the data center sector. Planning activities rose month-over-month, the number of new project starts increased, contractors' backlog hit a new high since 2023, and job vacancies in the construction industry reached a 10-month peak. However, behind these figures lies a stark contrast between the AI-building frenzy and the weakness of ordinary private projects.

As Ken Simonson, Chief Economist of the Associated General Contractors of America, put it, contractors are facing a "double whammy"—material prices are rising at the fastest pace since the pandemic, while bid price growth is slowing. For contractors without data center projects, the market environment is actually more severe than the numbers suggest.

AI Capital Influx Reshapes Engineering Demand Structure

The explosive growth in data center demand directly stems from a sharp surge in artificial intelligence infrastructure investment. Tech giants and cloud service providers are investing in GPU clusters, cooling systems, and high-density power facilities at an unprecedented pace. According to Dodge Construction Network data, multiple hyperscale data center projects entered planning or broke ground in May alone, with individual project investments often reaching tens of billions of dollars.

This capital influx has completely reshaped the construction industry's order structure. Anirban Basu, Chief Economist of the Associated Builders and Contractors, pointed out that the highest job vacancy level in 10 months "reflects exceptional demand for key roles in data center construction," such as electrical engineers, cooling system installers, and data center project managers. Contractor reports show that companies holding data center orders have significantly fuller pipelines, while those relying on commercial real estate, office buildings, or retail projects face shrinking orders.

Cost Pressures and Supply Chain Bottlenecks

Despite strong demand, data center construction does not come without costs. In May 2026, the year-over-year increase in building material input prices hit a post-pandemic high, with copper, steel, and semiconductor-related components continuing to rise. In addition, lead times for specialized equipment (such as transformers and uninterruptible power supplies) have extended to over 18 months, forcing developers to lock in capacity early.

On the labor front, competition for skilled workers has shifted from traditional construction areas to data center installation and commissioning. Many projects have had to pay premium overtime rates or recruit skilled technicians from overseas, further driving up project costs. These cost pressures, in turn, suppress the willingness to launch projects in other non-AI sectors, creating a vicious cycle.

Long-Term Risks of Single-DependencyThe over-reliance of the U.S. construction economy on the data center industry is cause for concern. Historically, any single construction sector’s concentrated boom has led to subsequent overcapacity and cyclical downturns. Although the current data center surge is supported by real AI demand, if the technology path changes (e.g., new chips reduce power consumption) or AI capital spending slows, projects under construction may face delays or cancellations.

Furthermore, data centers are typically located in suburban areas with ample power supply and lower land costs, having little spillover effect on urban core commercial office, retail, or residential markets. This means the data center boom cannot drive broader urban renewal or public transportation construction, and the regional economic benefits are limited.
