Data Centers, Not Offices, Are Driving America's Construction Boom

Overall U.S. construction spending fell 0.1 percent in June, missing forecasts of 0.3 percent growth, according to the Census Bureau. May's number got revised down too, from 0.1 percent growth to flat. Compared to a year ago, total construction spending is down 3.2 percent.

Buried inside that soft headline number is a category growing at a remarkable rate: office construction, up 2.8 percent in June alone, up 7.3 percent year-to-date, and up 15.1 percent compared to June of last year.

Remote work is still widespread. Workforce growth is slow. No major corporate headquarters are being built at a 15 percent annual clip in 2026.

They're not. According to Breitbart's analysis of the Census Bureau's detailed construction data, general office construction, the traditional stuff, is actually down 12.1 percent from a year earlier and fell 2.2 percent in June. Financial-sector office spending is a rounding error, just $2.7 billion annualized against $115.8 billion in total private office spending.

The growth is data centers. Data center construction jumped 7 percent in June alone and is up 45.8 percent from a year ago, running at a $68.3 billion annualized pace. That's now bigger than traditional office construction, which sits at $44.2 billion annualized.

The pace of change here is unusual. The Census Bureau didn't even break out data centers as their own line item until it released May 2024 data. That year data center spending grew 74 percent, jumping from just under $20 billion to $34.8 billion. Looking back further, from 2014 to 2021 data center spending grew from $1.8 billion to around $10 billion, a 27.7 percent annualized rate that was already fast. Since 2022, the growth rate has accelerated to roughly 58 percent annualized. June's pace is more than five times the entire 2022 total.

An earlier snapshot of the same data, from April, showed the same pattern. AI data center construction was up 28.1 percent year-over-year to $50.7 billion, now 52 percent of all private office construction, up from 44.5 percent a year earlier and just 32.9 percent two years earlier. That is a category more than doubling its share of the pie in two years.

The electricity buildout tells the same story from a different angle. Private power construction hit a $148.7 billion annualized rate in April, up 6 percent year-over-year, and the electric subcategory specifically, covering substations, transformers, and backup systems, climbed to $127.1 billion, up 7.3 percent from a year earlier. Electric now makes up 85.4 percent of private power construction spending, the highest share on record in this comparison. An economy trying to power thousands of AI server farms simultaneously requires enormous infrastructure investment.
