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.

Constellation Energy Corporatio CEG Winner Conviction: high
Constellation Energy runs the largest US nuclear fleet and is the core play in this thesis. Long-term power purchase agreements such as the 1.1-gigawatt Meta deal for the Clinton plant turn existing reactors into predictable cash flow machines for the AI era.
Vistra Corp. VST Winner Conviction: medium
Vistra combines a nuclear fleet with broad power generation, giving leveraged exposure to AI power demand. It has signed power purchase agreements with Meta for several reactors in Ohio and Pennsylvania, including an option on a new 300-megawatt SMR.
BWX Technologies, Inc. BWXT Winner Conviction: medium
BWX Technologies manufactures nuclear reactor components and is positioned in both the SMR and defense markets. It is expanding its US manufacturing capacity, including via a strategic acquisition in 2026, and benefits from the build-out of new reactors rather than just ongoing operation.
Denison Mines DNN Winner Conviction: low
Denison Mines is a speculative miner highly leveraged to the uranium price. It has made the final investment decision on its Phoenix ISR project, with production only starting around 2028, so the stock hinges mainly on rising uranium prices and project execution. Speculative.
