Nuclear and Uranium Revival
AI power hunger, SMRs and a tight uranium supply drive a structural upswing in nuclear energy.
After decades of stagnation, nuclear power is seeing a broad revival because AI data centers demand stable low-carbon baseload power at an unprecedented scale. Hyperscalers such as Meta, Amazon and Microsoft are locking in the output of existing reactors via long-term power purchase agreements, while governments in the US, Europe and Asia back new capacity. At the same time the uranium market has slipped into a structural deficit after years of underinvestment, with the spot price near 86 US dollars per pound in 2026 after a brief spike above 100 dollars. The thesis spans the fuel, reactor technology and the utilities that sell the power.
Mechanism
US data center power demand could rise from around 176 to as much as 580 terawatt hours by 2028, outstripping available grid capacity in several regions. Nuclear provides round-the-clock baseload with no emissions, which is why tech firms contract reactor output directly and make operator cash flows more predictable. More reactors and license extensions raise uranium demand while supply stays sluggish after a decade of mine underinvestment, supporting prices and margins along the chain.
Catalysts
New and expanded power purchase agreements between hyperscalers and reactor operators, such as Meta deals with Constellation and Vistra. Progress and approvals on small modular reactors plus government programs supporting new capacity. Final investment decisions and construction starts at uranium mines such as Denison Phoenix project, plus a sustained high uranium price.
Risks
Valuations of many nuclear and uranium names are already high after the rally and price in a lot of growth, leaving them exposed to setbacks. New reactors and SMRs are capital intensive, carry long lead times and face regulatory and construction delays. The uranium price is volatile and can correct sharply, and any cooling of AI power demand or a safety incident could weigh on the whole thesis.
Time horizon
This is a multi-year structural thesis: operators of existing reactors already benefit from offtake deals today, while new SMRs and uranium mines such as Phoenix only deliver meaningfully around 2028. Investors should plan for a multi-year horizon and interim volatility.
