The U.S. Census Bureau released long-delayed October 2025 construction spending data on Friday, providing the first official look at the construction sector's performance since a 43-day government shutdown halted data collection. The report showed total construction spending rose 0.5% in October to a seasonally adjusted annual rate of $2.175 trillion—a modest gain that masks significant variation beneath the surface.
The most striking finding: spending on data center and power infrastructure projects has surged fivefold since 2024, driven almost entirely by artificial intelligence-related demand. This AI-fueled building boom is reshaping the construction landscape and providing a growth engine that offsets weakness in other sectors, particularly residential construction.
The Delayed Data
Friday's release was highly anticipated after a prolonged data drought:
Shutdown Impact
The 43-day government shutdown that began in late November 2025 and stretched into early January 2026 halted most federal statistical reporting. The Census Bureau's monthly construction spending report, normally released on the first business day of each month, was among the delayed releases.
Catch-Up Mode
The Bureau is now working to release backlogged data, with November figures expected in early February. The delays have complicated economic analysis, leaving policymakers and investors flying partially blind during a critical period.
What October Showed
The October data depicted an economy adapting to elevated interest rates and shifting priorities:
- Total construction: $2.175 trillion annualized, up 0.5% from September
- Private residential: Down 0.3%, reflecting mortgage rate sensitivity
- Private nonresidential: Up 1.2%, led by manufacturing and data centers
- Public construction: Up 0.1%, with highway spending flat
The AI Data Center Boom
The headline story in construction isn't houses or highways—it's the explosive growth in data center construction driven by artificial intelligence:
Fivefold Increase
According to ConstructConnect data, data center construction spending reached $27.8 billion in 2026 projections, rebounding dramatically from $16.5 billion in 2025 and representing a fivefold increase from 2024 levels. This surge reflects the massive infrastructure requirements of AI training and inference.
Geographic Concentration
Data center construction has concentrated in regions with favorable power costs, land availability, and fiber connectivity:
- Northern Virginia: The world's largest data center market continues expanding
- Phoenix area: Low power costs attract hyperscale facilities
- Texas: Abundant power and business-friendly environment
- Midwest: Emerging markets in Ohio, Indiana, and Illinois
Power Infrastructure
Data centers require enormous power supplies, driving parallel investment in electrical infrastructure. Power generation and transmission projects are growing at the fastest rate in decades as utilities race to meet AI-driven demand.
"The AI infrastructure buildout is the most significant driver of construction activity we've seen since the post-war housing boom. Every major technology company is racing to build capacity."

Residential Construction Weakness
In contrast to booming data centers, residential construction continues to struggle:
Mortgage Rate Impact
With mortgage rates hovering near 6%, demand for new homes has softened from pandemic-era peaks. Builders have responded by slowing starts and focusing on entry-level price points where demand remains relatively stronger.
Renovation Strength
One bright spot: renovation and remodeling spending has held up better than new construction. Homeowners locked into low mortgage rates are choosing to improve existing homes rather than move, supporting renovation contractors.
Regional Variation
Residential construction patterns vary significantly by region:
- Sun Belt: Texas and Florida continue seeing relatively stronger activity
- California: High costs and regulations constrain new building
- Midwest: Affordable markets show resilience
- Northeast: Limited land and high costs limit new construction
Infrastructure Act Spending
Federal infrastructure spending from the 2021 Infrastructure Investment and Jobs Act continues flowing through the construction sector:
Road and Bridge Projects
Highway construction ran at a $141.6 billion annual rate in October, roughly flat from September. Major reconstruction projects for aging bridges and Interstate highways are underway across the country.
Expiration Concerns
Authorization under the Infrastructure Act expires in October 2026. If Congress fails to reauthorize, the pace of new infrastructure project awards could slow significantly. The construction industry is urging early action to avoid uncertainty.
Water and Wastewater
Investments in water infrastructure—replacing lead pipes, upgrading treatment plants, improving stormwater management—remain active, though at a slower pace than road construction.
Manufacturing Construction
The reshoring trend continues driving manufacturing facility construction:
Semiconductor Plants
CHIPS Act-funded semiconductor fabrication plants represent some of the largest construction projects in American history. Intel, TSMC, and Samsung facilities in Arizona, Ohio, and Texas are in various stages of construction.
Battery Factories
Electric vehicle battery plants are under construction across the South and Midwest, though some projects have been delayed or scaled back as EV demand growth has slowed.
Pharmaceutical Facilities
Drug manufacturing reshoring—accelerated by supply chain concerns during the pandemic—continues driving facility construction.
Labor and Material Costs
The construction sector continues grappling with elevated costs:
Labor Shortages
Skilled labor remains in short supply, particularly for electrical and specialty trades. The AI data center boom has intensified competition for workers with relevant expertise.
Material Costs
While some material costs have moderated from 2022 peaks, overall construction costs remain elevated. Copper, electrical equipment, and concrete show particular strength reflecting infrastructure demand.
Productivity Investments
Contractors are increasingly investing in technology—prefabrication, modular construction, robotics—to improve productivity and offset labor constraints.
2026 Outlook
Industry forecasts suggest modest overall growth with significant sector variation:
- Overall spending: Expected to grow 0.4% in 2026, following a 4.7% decline in 2025
- Data centers: Continued strong growth, potentially 30-40% increases
- Residential: Flat to slightly positive, dependent on mortgage rates
- Infrastructure: Stable through October 2026, uncertain thereafter
- Manufacturing: Strong but moderating from 2024-2025 peaks
Investment Implications
The construction data offers insights for investors:
Winners
- Electrical contractors: Data center and power infrastructure exposure
- Equipment makers: Caterpillar, Deere benefit from activity
- Materials suppliers: Aggregates, cement, and steel demand remains solid
- Engineering firms: Design work for complex facilities
Challenged
- Homebuilders: Rate sensitivity limits upside
- Office construction: Remote work reduces demand
- Retail construction: E-commerce continues shifting activity
The Bottom Line
October's construction spending data, though delayed, confirms the sector's ongoing transformation. AI-related data center construction is providing a powerful growth engine that partially offsets residential weakness and infrastructure spending uncertainty.
For the economy, the construction sector remains a significant employer and economic contributor. The AI infrastructure buildout ensures activity will remain elevated for years, even as traditional construction categories face headwinds.
For investors and policymakers alike, the message is clear: the AI revolution isn't just changing how we work and communicate—it's reshaping the physical landscape of American construction.
