National nonresidential construction spending slid 1.5% in May, according to a new analysis of data published by the U.S. Census Bureau by Associated Builders and Contractors (ABC). On a seasonally adjusted annualized basis, nonresidential spending totaled $1.267 trillion.
“Private nonresidential construction spending shrank for the seventh consecutive month in May and is now down 6.6% on a year-over-year basis,” said ABC Chief Economist Anirban Basu. “This weakness is largely due to the ongoing decline in manufacturing-related construction spending as CHIPS Act-supported projects wind down, yet overall there are few sources of momentum in the segment.”
Spending was up on a monthly basis in 11 of the 16 nonresidential subcategories. Private nonresidential spending was down 0.3%, while public nonresidential construction spending was up 0.4% in May.
“Yes, the amusement and recreation category continues to grow at a healthy pace, and the religious category has rebounded meaningfully over the past year,” Basu said. “But those modestly sized segments are far too small to carry the broader nonresidential market, especially given the weakness in larger categories. For instance, warehouse construction spending, which appeared to stabilize at the start of 2026, has now fallen for three consecutive months and is down 8.5% year over year, while the general office category remains in a state of freefall, down 11.9% since May 2025.
“For now, momentum remains largely concentrated in the data center segment,” he continued. “As seen in ABC’s most recent Construction Backlog Indicator release, those fortunate enough to have data center work have significantly longer backlogs (11.6 months) than those that do not (8.6 months).”
