The U.S. Department of Energy announced a $100 billion private investment plan to transform a decommissioned uranium enrichment site in western Kentucky into a facility being marketed as the Paducah American Energy Hub — a redevelopment effort that state officials characterise as one of the most extensive economic undertakings in the state's history.

Under the direction of Energy Secretary Chris Wright, a coalition drawn from the private sector is set to develop an AI and high-performance computing campus that would draw its power from newly built energy infrastructure. Across a buildout timeline stretching toward 2032, the project is anticipated to bring roughly 8,000 positions in construction along with around 600 roles tied to ongoing operations.

Brookfield Asset Management (NYSE: BAM) holds the development contract for constructing a 1.8 GW campus dedicated to AI and high-performance computing, while a separate assignment puts NextEra Energy (NYSE: NEE) in charge of bringing 2 GW of natural gas-fired generation online alongside 2.6 GW of battery-based energy storage capacity.

Built around dedicated power infrastructure with the capacity to push surplus electricity back into the wider regional network, the scheme aims to keep utility costs from climbing for households and businesses in the surrounding area. A closed-loop water-recirculation system, designed to keep water cycling internally rather than drawing from outside sources, is also set to be installed across the campus.

Facility administrators note that water use at the site runs well below the volumes the land's previous occupant — the Paducah Gaseous Diffusion Plant, a Cold War-era uranium enrichment operation — was designed to accommodate, given that the older plant had been built with the capacity to pull up to 30 million gallons a day from the Ohio River.

Questions about how much spending on artificial intelligence infrastructure the market will tolerate have resurfaced at a point when the Paducah project is already under way. At a joint appearance, Trump, Oracle's Larry Ellison, OpenAI's Sam Altman, and SoftBank's Masayoshi Son unveiled Stargate — a privately held venture committing up to $500 billion over four years toward building out large-scale AI data centres alongside the energy infrastructure needed to power them across the United States.

Supporters describe Stargate as an AI infrastructure undertaking without parallel in its category, designed to give the United States a leading position in the technology over competing nations. Built on Oracle's cloud and infrastructure technology, the venture draws its core technical backbone from that platform.

Groundwork for the project got underway in Abilene, Texas, where plans called for a cluster of data centre structures — each spanning roughly 500,000 square feet — intended to accommodate the computing infrastructure that next-generation AI models are expected to require.

Reports published in January indicated that JPMorgan Chase was encountering difficulty placing the $38 billion in construction financing it had underwritten for the Stargate AI data centre project, with institutional buyers pulling back amid concerns about concentrated exposure to the technology sector. For more than half a year, lenders worked to place the debt packages tied to the Stargate data-centre projects in Texas and Wisconsin, yet institutional buyers showed little appetite for instruments carrying concentrated exposure to single-tenant artificial-intelligence facilities of that scale.

Oracle holds the facilities under a lease arrangement, and a rating action by S&P in July pushed the company one notch down to BBB — leaving it a single step above the threshold between investment-grade and speculative territory — with data centre spending identified as the primary factor behind the move. Investors holding the debt sought a higher return before agreeing to absorb it, and the banks ended up selling at a discount to get the paper off their books.

OpenAI put its Stargate UK data centre plans on hold that April, with elevated industrial power costs and an unsettled regulatory environment given as the reasons behind the decision. Under the Stargate UK arrangement, hardware partners Nvidia and Nscale were set to supply a growing pool of AI processing units to locations across North-East England — among them Cobalt Park near Newcastle and a site at Blyth — with an initial deployment of 8,000 GPUs earmarked to expand progressively toward a ceiling of 31,000.

The work was put on hold rather than abandoned entirely, with the company indicating that a return to active development hinges on conditions that would support sustained infrastructure investment over the long term. Among those affected was Nscale, a UK infrastructure company founded by Josh Payne that had been growing its operations and exploring a potential stock market listing, alongside the country's broader ambitions to build out a domestically controlled AI capability.

Broadcasting reports placed Oracle's Project Jupiter — a New Mexico campus stretching across 1,400 acres with 2.45 gigawatts of planned generating capacity — in a holding pattern after the company did not obtain the necessary state and federal land-use authorisations for a proposed natural gas facility. A force majeure notice was delivered by Oracle to its lender, Blue Owl Capital. Following that announcement, the firm revealed a pivot toward solid oxide fuel cells — a form of SOFC technology whose deployment at anything approaching this scale had not previously been attempted.

Opposition to data centre development has taken hold in communities spanning the United States, Europe, and Asia, with residents and local groups raising concerns about the environmental toll and economic burden tied to AI infrastructure buildout. According to Gallup polling data, about seven in ten Americans do not want AI data centres built where they live. Across the country, opposition to data centre development has put more than $130 billion worth of projects on hold or under formal review, with tallies from available records pointing to upward of 500 localities having enacted bans or moratoriums on such construction.
