The consensus on AI data centre construction costs is that the spending boom is unstoppable. The data make that harder to dismiss than the critics would like, but the constraints accumulating around that boom deserve more weight than the headline growth figures typically receive.
Construction spending on data centres hit a seasonally adjusted annual rate of $75 billion in July, up 6.2% month-over-month and 57% year-over-year, according to Census Bureau data cited by Wolf Street. Since the beginning of 2021, monthly construction spending on data centres has risen by 717%, tracing what Wolf Street describes as a near-exponential curve. The caveat, noted plainly in the same analysis: exponential curves eventually fizzle. The question is when, and from which direction the pressure arrives first.
New York’s Data Centre Moratorium and What It Signals
The regulatory pushback is moving faster than the construction-optimist narrative typically allows. On 4 June 2026, both houses of the New York State Legislature passed the Responsible Data Center Development Act (S10642/A11560), which would impose a one-year moratorium on the issuance of certain permits for large data centres, according to Harris Beach Murtha. If signed by Governor Kathy Hochul, New York would become the first state in the nation to enact a statewide data centre moratorium.
The grid pressure behind that move is not abstract. As of May 2026, nearly 12 gigawatts of data centre load requests were sitting in the New York Independent System Operator interconnection queue, with more than two-thirds of those capacity requests having entered the queue in 2025 alone, according to Sheppard. The grid cannot absorb that volume of demand instantaneously, and the Legislature’s response is to pause and rethink rather than simply approve and cope.
Under the legislation, the Empire State Development is directed to issue a Community Investment Framework within 60 days, providing guidance to local entities on infrastructure improvements, child care investments, and direct financial support for communities, according to the Governor of New York Official Site. That framing suggests the moratorium is not purely restrictive: it is also an attempt to structure how the buildout proceeds if and when it resumes. Whether that produces workable rules within the moratorium’s window, or simply delays the same pressure by a year, remains to be seen.
AI Data Centre Construction Costs Are Climbing Beyond the Build
The $75 billion annual rate covers only the buildings, surrounding improvements, and equipment integrated into those buildings, such as HVAC systems. It excludes the servers, racks, networking and optical equipment, power infrastructure, and generators: in other words, the most capital-intensive components of a functioning facility. The true cost envelope is considerably wider than the construction figures alone suggest.
Across the supply chain, AI data centre construction costs are rippling into broader inflation metrics. The Producer Price Index for construction materials, covering steel mill products, concrete, lumber, and gypsum, spiked by 10.5% year-over-year, the largest increase since June 2022. At the product level, the PPI for fabricated structural metal bar joists and concrete reinforcing bars rose by 17.7% year-over-year. Since January 2021, the construction materials PPI has risen 46%; since January 2020, by 58%.
The labour market is tightening alongside materials. Shortages of specialised workers, particularly electricians, have emerged as a binding constraint. Semiconductor prices have risen as memory chip shortages spread from AI servers into consumer electronics and from there into inflation data. On the power generation side, bottlenecks in gas turbine supply have led companies to repurpose retired jet engines. Musk acquired APR Energy in July to alleviate shortages for his own data centres, and separately confirmed that SpaceX will begin manufacturing turbine blades and vanes, the primary bottleneck for gas turbine producers.
The Revenue Question That Nobody Is Answering
Behind the construction data sits an unanswered commercial question. The investment thesis rests on AI generating trillions of dollars in new revenues. Nobody has yet demonstrated where those revenues come from or in what timeframe. The spending continues regardless, funded by corporate cash, debt, and equity issuance, with the knock-on effect of competing for the same pool of capital as government bonds and pushing yields higher.
The consensus may be overweighting the near-term momentum in construction spending and underweighting both the regulatory friction now codified in New York and the inflation feedback loop visible in the PPI data. A moratorium in the first state is not the end of data centre construction. But it is also not nothing: 12 gigawatts of queued demand meeting a one-year permit freeze in a major market is a stress test the bull case has not yet priced in.
