The idea
I believe AI data centers and electrification are pushing baseload power demand past what the grid can add in firm, clean capacity, and nuclear is the only real fix. Most of the portfolio sits in existing fleet owners signing power deals and in the uranium and enrichment bottleneck created by years of underinvestment, with builders and components riding the construction cycle. A small slice is set aside for next-gen reactor developers as a long-dated option, and I keep some cash on hand. I'd rethink this if utilities start meeting demand with other firm capacity instead of nuclear.
What it owns
- Companies that already own nuclear plants are signing premium power contracts with data-center operators, turning nuclear capacity into a scarce, high-margin product. · Constellation EnergyIt operates the largest US nuclear fleet and pioneered the template for premium power deals with hyperscalers, making it the clearest large-cap bet on nuclear as a premium product., VistraIt owns multiple nuclear plants acquired at attractive prices and can capture both regulated returns on grid supply and unregulated upside from data-center power deals., Talen EnergyIt anchors a landmark data-center power agreement at a smaller scale than larger peers, offering more direct leverage to incremental deal flow., Public Service Enterprise GroupIt operates a regional nuclear fleet and is negotiating direct data-center supply contracts, offering regulated stability combined with exposure to the new demand story., Dominion EnergyIt serves the densest data-center market in the US, owns nuclear generation, and controls a site designated for SMR development, combining near-term and long-term nuclear exposure.35%
- Western uranium supply and enrichment capacity face rising demand while Russian sources are banned, creating a structural shortage that favors established producers and fuel makers. · CamecoIt is the dominant Western uranium producer with tier-one assets and holds a stake in a reactor supplier; utilities seeking non-Russian fuel sources turn to it first., Global X Uranium ETFIt provides diversified basket exposure across uranium miners and developers, capturing the fuel supply squeeze without concentration risk on any single asset., Centrus EnergyIt is the only US-licensed producer of advanced reactor fuel just as Russian enrichment is being excluded, making it the tightest supply constraint in the take., Uranium Energy CorpIt is restarting domestic US uranium production with no hedges, providing maximum exposure to both rising uranium prices and policy support for domestic fuel supply., NexGen EnergyIt owns the highest-grade undeveloped uranium deposit in the world, appreciating in value as the supply squeeze persists and development timelines move closer.27%
- Reactor construction, maintenance, and component supply chains generate steady revenue across the entire build cycle regardless of which reactor design ultimately dominates. · GE VernovaIt supplies turbines and services to existing reactors and owns an SMR design with utility orders, generating revenue across fleet maintenance and new builds., BWX TechnologiesIt holds a monopoly on US naval reactor supply and is growing commercial fuel fabrication for advanced reactor types, winning under every build scenario., Curtiss-WrightIt supplies critical components to all major reactor types, from current plants to next-generation designs, capturing revenue across maintenance and new construction.17%
- Small modular reactors represent a longer-term expansion path; positions are sized to capture upside if deployment accelerates without overstating near-term uncertainty. · OkloIt develops advanced reactors with a build-own-operate model and a customer base concentrated in data centers, offering binary upside if deployment timelines hold., NuScale PowerIt holds the only SMR design with full regulatory approval and is pursuing its first commercial orders; sized as an option given execution and dilution risk.9%
