Data center construction is expanding at such a rapid pace across North America that the majority of new build in the sector is now expanding beyond the initial, traditional markets. Texas is about to unseat Virginia as the world’s largest data market, according to a new report from JLL, which calls it an “inflection point.” About 64% of the 35-gigawatt construction pipeline now extends beyond so-called mature markets, like Virginia, which has long been the largest data center market. Data center vacancies at the end of 2025 remained at a historic low of 1% for the second year in a row. “The data center sector has officially entered hyperdrive,” said Andy Cvengros, executive managing director and co-lead of U.S. data center markets at JLL. “Record-low vacancy sustained over two consecutive years provides compelling evidence against bubble concerns, especially when nearly all our massive construction pipeline is already pre-committed by investment-grade tenants.” Almost all, 92%, of the capacity currently under construction is pre-committed, which indicates that vacancy is likely to remain quite low at least through 2030, according to JLL. The demand is now being driven by hyperscalers and artificial intelligence, and headwinds to new development are keeping construction less robust than it could be. JLL also noted that the top five hyperscalers have $710 billion in planned capital expenditures in 2026 to build out necessary infrastructure. Lenders appear to be eager to get in on that, with a record $75 billion in total financing last year. Nuveen, a global real estate development firm, is taking a short-term approach to the sector, capitalizing on the current strong demand but following a build-and-sell model to mitigate risk. “There really is quite a bit of demand, and we think that in the next five years there’s not an oversupply situation,” said Chad Phillips, global head of Nuveen Real Estate, adding that the long term is less predictable. “There’s going to be evolution pretty quickly, and so that’s why we’re looking at sort of shorter-term builds and then sells.” There is, of course, considerable risk surrounding infrastructure constraints, specifically power. Grid connection timelines average about four years or even longer. As a result, major tenants need to secure capacity many years in advance. That is driving the expansion into new markets that have more of that power available. “A lot of companies are considering building onsite power generation,” said Andrew Batson, global head of data center research at JLL. “It reduces risk. Ultimately, though, the overwhelming majority of operators want grid connectivity long term.”
