Opinion: AI Infrastructure Buildout Is Largely Fictional, Grid Data Shows

Only ~33% of 241GW disclosed US data center capacity is under active development

Drawing on Wood Mackenzie data, the article contends the remaining two-thirds of the pipeline consists of speculative land deals, uncleared permits, and capacity assumptions tied to power generation that does not yet exist. Economist Paul Kedrosky is cited in support of this framing.

US data center capacity pipeline additions halved from Q3 to Q4 2025

The article attributes this to persistent 'load-queue challenges' — the backlog of projects waiting for grid interconnection approval. The author reads this deceleration as early evidence that the buildout's momentum is already softening.

58% of committed data center capacity depends on wires-only utility arrangements with no confirmed generation source

In a wires-only arrangement, a utility agrees to deliver power to a site's fence line but takes no responsibility for generating that power. The article argues this means the majority of planned AI campuses have no confirmed path to the electricity they would need to operate.

PJM, one of the largest utility providers in America, has committed power to data centers at 3x the rate new generation capacity is coming online

The article frames this gap not as a minor timing lag but as a structural mismatch that cannot be resolved by optimism alone. It is presented as a concrete illustration of the broader argument that physical grid constraints will eventually override speculative planning.

Total US data center capex ~$948 billion; capex growth decelerated for first time since 2023

The author treats this deceleration as a leading indicator that the AI infrastructure boom is beginning to lose momentum, even before the harder collisions with grid and power constraints materialize.

Texas leads US data center pipeline; New Mexico, Indiana, Wyoming saw relative Q4 2025 growth

Geographic distribution data from the article provides context on where speculative and active development is concentrated, though the author's broader argument applies across all regions.

Author argues AI buildout sustained by collective belief in inevitability rather than executable infrastructure plans

The article's central thesis is that the industry operates on the assumption that obvious problems will resolve themselves — and that this faith cannot override the physics of power generation and grid capacity.
