AI Capex Surge Drives New Demand for Nuclear Power
Alphabet, the parent of Google, lifted its 2026 capital-expenditure outlook from $180-$190 billion to $195-$205 billion. Amazon raised its annual capex estimate from $200 billion to $220 billion, and Meta is financing additional AI spending through new debt. The three firms’ expanded budgets signal that AI-related investment is accelerating rather than slowing, a trend that benefits companies supplying the electricity needed for AI data centers.
Background: AI Data Centers and the Push for Low-Carbon Electricity
Large-scale AI models require massive, reliable power. The United States Nuclear Regulatory Commission reports that many reactors originally licensed for 40 years are operating up to 80 years, and newer designs promise even longer lifespans. Partnerships are emerging between tech firms and utilities: in late 2024 Microsoft and Constellation Energy announced plans to restart an idle reactor at Pennsylvania’s Three Mile Island to power a Microsoft data center, while Vistra is collaborating with Amazon and Meta to deliver nuclear electricity to their AI facilities. These developments illustrate a shift from a simple customer-provider model to joint ventures aimed at securing low-carbon, high-capacity energy.
Cameco’s Position in the Growing Uranium Market
Cameco Ltd., a Saskatchewan-based uranium miner, reported sales of 33 million pounds of triuranium octoxide last year and holds a 49 % stake in Westinghouse Electric, which services more than 90 reactors in 21 countries. The company posted $3.5 billion in revenue and $627 million in adjusted net earnings, up from 2024 figures. The World Nuclear Association projects that global nuclear capacity could double by 2050, while Goldman Sachs forecasts the number of operating reactors could rise from roughly 440 today to 500 by 2030, with an additional 400-plus reactors proposed or planned.
Outlook and Potential Impact
Because constructing new nuclear plants takes years, the immediate surge in AI data-center electricity demand is likely to be met by existing gas-turbine solutions such as those from GE Vernova. Over the longer term, however, the expanding reactor fleet is expected to increase uranium consumption, positioning Cameco to benefit from sustained AI-driven power needs. Analysts suggest that while short-term stock performance has been muted, the “second act” of nuclear expansion could separate winners from losers, with Cameco poised as a probable winner once new reactors become operational.
