US Manufacturing Construction Spending Plateaus in 2026 After Historic Surge
U.S. manufacturing construction spending has entered a clear period of consolidation and decline in 2026, marking a transition from the initial megaproject shell-building phase to equipment installation.1 According to the U.S. Census Bureau and FRED economic data, total spending on manufacturing construction has fallen significantly from its 2025 peak, a phenomenon increasingly described as the "CHIPS Sunset Effect."
In June 2026, the seasonally adjusted annual rate (SAAR) of manufacturing construction spending fell to $172.67 billion, continuing a steady month-over-month decline from $181.88 billion in February 2026. For the first half of 2026 (January through June), total manufacturing construction spending amounted to $87.01 billion, representing a sharp 22.1% decline compared to the $111.75 billion recorded during the first half of 2025.
This deceleration is particularly visible in private manufacturing construction. In May 2026, private manufacturing construction spending was recorded at $174.76 billion, down 21.9% from approximately $224 billion in May 2025.
While this pullback indicates that the peak of raw physical factory shell construction has passed, it does not represent a failure of the reshoring thesis. Instead, capital expenditure is shifting from civil engineering and concrete pouring to high-margin electrical, mechanical, and automation equipment fit-out inside these newly built structures2, as evidenced by the record backlogs and order surges at specialty contractors and power management firms like Specialty Contractors Reap High-Margin Rewards of Reshoring and Data Center Capex and Eaton Rides Massive Wave of Data Center and Megaproject Orders in Q2 2026.
