Data Center Projects Account for All Nonresidential Construction Spending Growth, Masking Sector-Wide Decline

Inside the U.S. Census Bureau headquarters in Suitland, Maryland, on Tuesday morning, the July 2026 construction spending report revealed a stark divide in the American built environment. Overall construction spending slipped 0.5% to a seasonally adjusted annual rate of $2.157 trillion, dragged down by a residential sector still constrained by high borrowing costs. Yet nonresidential construction managed to inch up 0.1% to $1.286 trillion. That microscopic gain, however, masked a massive structural shift: every single dollar of that nonresidential growth came from the explosive expansion of artificial intelligence data centers.[2][4]

For a regional developer planning a new medical clinic or a logistics company trying to build a regional warehouse, this statistical quirk translates into a tangible local bottleneck. The sheer scale of tech infrastructure projects is absorbing regional labor pools, monopolizing heavy electrical components, and keeping commercial construction costs elevated even as demand for traditional real estate cools.

While national indices show a booming construction sector, the reality on the ground is a two-tiered market where hyperscale tech projects command the resources, leaving conventional commercial builds competing for whatever labor and materials remain.[8]

The concentration of capital is unprecedented in recent commercial real estate history. "The increase in nonresidential construction spending that occurred in July was entirely due to data centers," Anirban Basu, chief economist at Associated Builders and Contractors, said in a statement reviewing the Census Bureau figures.

"Excluding that booming category, nonresidential spending fell for the second straight month and is down to the lowest level since September 2023." Across the 16 nonresidential subcategories tracked by the government, spending declined in eight of them during July, including a 1.0% drop in manufacturing facilities, a 0.5% decline in transportation infrastructure, and a 0.5% pullback in healthcare construction.[1][2]

The financial footprint of the artificial intelligence rollout is staggering. According to an analysis of the Census Bureau data by Piedmont Crescent Capital, data center construction accounted for $37.2 billion in spending during the first seven months of 2026. That represents a 34.8% surge compared to the same period in 2025.

Consequently, data centers now constitute 57% of all private office construction in the United States, up from 47% a year earlier. Meanwhile, spending on every other type of traditional office building fell by 9.5% over the same seven-month window, reflecting a permanent shift in how corporate America utilizes physical space.[1][6]

The ripple effects of this digital infrastructure boom are also propping up the utility sector. Data centers require immense amounts of electricity, prompting a parallel surge in energy infrastructure development. "Nonresidential activity is even more concentrated given that the power category, which has been boosted by the electricity needs of data centers, has also grown substantially over the past year," Basu noted.

Spending in the power sector increased 5.3% year-over-year in July, as utility providers scrambled to build new substations, transmission lines, and generation facilities to feed the gigawatt-scale demands of modern server farms.[1][3]

Beyond tech and power, the only other bright spot in the July 2026 data was publicly funded infrastructure. "Only three categories are propping up construction spending: data centers, power and highway projects," Ken Simonson, chief economist for the Associated General Contractors of America, observed following the data release.

Highway and street construction spending increased 4.5% year-over-year, buoyed by the continued rollout of federal funds from the 2021 Infrastructure Investment and Jobs Act. However, public construction overall still dipped 0.2% for the month, pulled down by a 0.4% decline in residential public building and a 1.4% drop in conservation and development projects.[2][4]

The weakness in the broader commercial market is mirrored in the residential sector, where high mortgage rates continue to suppress new development. Private residential construction fell 1.3% in July to an annualized rate of $859.0 billion, marking the fourth consecutive monthly decline.

Single-family home building took the hardest hit, dropping 3.2% for the month and sitting 6.5% lower than in July 2025. For prospective homebuyers, the slowdown in single-family construction means housing inventory will likely remain tight through the end of 2026, keeping upward pressure on existing home prices even if the Federal Reserve begins to ease interest rates.[4]

The trajectory of the U.S. construction industry now hinges almost entirely on the capital expenditure budgets of a handful of hyperscale technology companies. If firms like Amazon, Microsoft, and Alphabet maintain their aggressive artificial intelligence buildouts, the headline construction figures will likely remain stable through the fourth quarter of 2026.

However, if that tech spending plateaus, the underlying fragility of the traditional commercial and residential markets will become impossible to hide. The next crucial indicator will arrive in late October, when third-quarter corporate earnings reports reveal whether the tech sector's appetite for new server space is finally beginning to match the physical limits of the construction industry.[5][7]
