Data Center Infrastructure Grew 27 Percent, and Permits Are Now the Bottleneck

Data center infrastructure grew 27 percent in one quarter

The worldwide data center physical infrastructure market grew 27 percent year over year to 14 billion dollars in manufacturer revenue in the second quarter of 2026, according to Dell'Oro Group's report published on October 14, 2026. The quarter extended a run of growth above 20 percent, driven by AI data center demand that continues to outpace supply. The modest slowdown from the first quarter of 2026 reflects a tougher comparison, not softer demand, according to the report.

The more important finding is not the growth rate. It is what Dell'Oro says is now holding the buildout back: not cancellations, but permits. Power availability, long-lead equipment, and community opposition are stretching project timelines, and the report calls siting and permitting the most serious near-term brake on the market. In other words, the industry can sell the capacity, but it cannot always plug it in.

Data center infrastructure growth, in numbers

Thermal management was the fastest-growing segment, expanding more than 40 percent year over year and matching its record share of revenue. Liquid cooling, led by direct liquid cooling, and heat rejection, the chillers that push heat outside the building, both outpaced the segment. That detail tells you what AI hardware actually demands: denser racks produce more heat, and air cooling alone no longer keeps up.

Dell'Oro also introduced a new five-segment customer structure in this report, breaking out hyperscalers, other cloud providers including neoclouds, colocation, telecom, and enterprise. That split matters because the buyers are no longer just the big cloud companies. Neoclouds and colocation providers are a growing share of demand, which spreads the buildout across more operators, more sites, and more local permitting fights.

Permits are the new bottleneck

The permitting story is playing out in public across the industry. AWS is sold out through 2027 as AI demand outruns the buildout. Denmark pushed datacenters to the back of the grid queue as requests hit 60GW. Data center demand doubled in six months, and permits became the bottleneck. Dell'Oro's report ties those threads together with a number: 14 billion dollars of infrastructure sold in a single quarter, into a system that cannot approve and connect sites fast enough to absorb it.

That mismatch has consequences beyond construction schedules. Delayed permits mean delayed capacity, which means higher prices for the capacity that exists, which is part of why cloud providers are sold out and why AI companies are signing power deals years ahead. It also means local communities have real leverage. A project that needs grid capacity, water for cooling, and local approval cannot simply be willed into existence by a hyperscaler's capital budget.

What operators should do about it

For operators, the practical response is to treat permitting as a first-class project risk, not an administrative afterthought. That means engaging grid operators and local authorities earlier, designing for liquid cooling and heat reuse from the start, and building realistic timelines that assume interconnection delays. It also means diversifying sites: a portfolio spread across grids and jurisdictions is less exposed to any single permitting logjam than a single mega-campus.

For everyone else, the Dell'Oro numbers are a useful reality check on AI hype. The buildout is real, the money is real, and the constraint is not demand or technology. It is the unglamorous work of getting permission to build, power to run, and cooling to keep the whole thing from overheating. Until that work speeds up, expect more headlines about sold-out capacity, delayed projects, and record infrastructure sales happening at the same time.
