June Nonresidential Construction Spending Up on Strength of Data Centers

National nonresidential construction spending rose 0.1% in June, according to an Associated Builders and Contractors analysis of data published by the U.S. Census Bureau. On a seasonally adjusted annualized basis, nonresidential spending totaled $1.277 trillion.

Spending was up on a monthly basis in 8 of 16 nonresidential subcategories. Both public and private nonresidential spending were up 0.1% in June. Private nonresidential construction spending was down nearly 5% from a year ago.

“Through April 2025, private nonresidential construction spending ascended to $806.1 billion on a seasonally adjusted annual rate basis, an all-time high,” said ABC Chief Economist Anirban Basu. “Since then, that figure has expanded only three times over the past 14 months.

“Despite an ongoing data center construction boom, private nonresidential construction spending has declined to a seasonally adjusted annual rate of $745.3 billion since the April 2025 peak, which translates into a decline exceeding 7%,” said Basu. “Tellingly, private nonresidential construction spending excluding data centers fell 0.6% in June 2026 and is down 7.9% year over year.

“Meanwhile, data center construction was up 7% in June and up 46% from a year ago. Contractors working on data centers continue to benefit from this momentum. According to ABC’s latest Construction Backlog Indicator, the 13% of ABC members under contract to work on data centers have significantly higher backlog (11.0 months) than the 87% that are not (8.5 months).”
