Nonresidential construction spending climbed 0.1% in June and is down 2.1% compared with June 2025, according to Associated Builders and Contractors.
For public construction, spending was up 0.1% for the month and is up 1.8% year to date. Private nonresidential spending increased 0.1% in June and is down 4.7% year to date. Spending was up for the month in eight of the 16 nonresidential subcategories.
“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%,” Basu continued. “Tellingly, private nonresidential construction spending excluding data centers fell 0.6% in June 2026 and is down 7.9% year over year.”
Basu said some contractors are benefiting from the data center boom.
“Data center construction was up 7% in June and up 46% from a year ago." Basu said. "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).”
