Nuclear & SMR
AI's power crunch makes nuclear the decade's structural long
Thesis. Hyperscaler power demand has collided with a grid that cannot add reliable baseload fast enough, and nuclear is the only carbon-free, 24/7 supply the AI buildout will pay a premium for. The trade splits cleanly: established nuclear operators (CEG, VST) are cash-generative businesses selling scarce megawatts today, while SMR developers (OKLO, NNE, SMR) are pre-revenue call options on a fuel and regulatory path that won't produce electrons before the end of the decade. After a violent 30-45% derating across the group, valuations have reset from euphoria toward something ownable — but the two buckets require completely different underwriting. Own the operators for the earnings; size the developers for the binary.
Where we are in the cycle. Post-euphoria digestion. The 2024-25 melt-up priced SMRs for perfection; the subsequent 30-45% drawdown has washed out the momentum crowd and reset the group closer to fundamentals — early innings for the underlying demand story, mid-cycle for the sentiment.
Macro context
- Hyperscaler AI datacenter demand driving multi-decade PPAs at premium prices — nuclear is the only firm, carbon-free baseload that meets the 24/7 requirement
- Bipartisan policy support: NRC modernization, ADVANCE Act licensing reform, DOE loan guarantees and restart funding, plus explicit federal push for domestic SMR fuel (HALEU)
- Structural US grid supply shortfall — load growth is outrunning new firm generation for the first time in a generation, and gas turbine backlogs stretch to 2029+
- SMR economics remain unproven — no US commercial unit is operating, and NuScale's cancelled UAMPS project is a live reminder that cost inflation kills deals
- Rising long-end rates penalize both capital-intensive nuclear buildout and long-duration pre-revenue optionality
- Behind-the-meter and colocation rules (FERC) could throttle the exact hyperscaler-nuclear pairings the whole thesis is priced on
Top picks
Constellation (CEG, ACCUMULATE, $305) is the highest-conviction name — best-in-class merchant nuclear fleet, real cash flow, and now 42% off its high; you're buying the derating, not a broken thesis. Vistra (VST, ACCUMULATE, $200) is the levered merchant-power complement with Meta/AWS PPAs and 43% revenue growth into a 29% pullback. Both are businesses selling scarce megawatts today, not slideware — accumulate the operators before the developers.
| Ticker | Company | Rating | Target | Upside |
|---|---|---|---|---|
| NNE | NANO Nuclear Energy Inc. Pre-revenue SMR optionality backed by $570M net cash, near 52-week lows with NRC review live and UAE talks pending. | ACCUMULATE | $28.00 | +48.3% |
| OKLO | Oklo Inc. Fortress-balance-sheet SMR optionality at a fresh 52-week low — accumulate the derating, size for binary regulatory risk. | ACCUMULATE | $70.00 | +46.1% |
| VST | Vistra Corp. Best-in-class AI-power merchant with Cogentrix, Meta/AWS PPAs and 43% revenue growth — buy the 29% pullback into leverage and insider selling. | ACCUMULATE | $200.00 | +28.4% |
| CEG | Constellation Energy Corporation Best-in-class nuclear baseload for the AI-power decade, now 42% off its high — accumulate the derating, not the panic. | ACCUMULATE | $305.00 | +27.2% |
| SMR | NuScale Power Corporation Fortress balance sheet and AI-power narrative offset by zero commercial revenue, relentless cash burn and Fluor's exit — a thematic option, not a business. | HOLD | $10.50 | +17.2% |
Watch list
Oklo (OKLO, $70) and NANO Nuclear (NNE, $28) are the fortress-balance-sheet SMR options worth monitoring — pre-revenue optionality on live NRC pathways, sized small for binary regulatory risk. NuScale (SMR, HOLD) stays a thematic option, not a business, until commercial revenue and a post-Fluor path materialize.
Risks
- SMR licensing or first-of-a-kind cost overruns that push commercialization past the AI-demand window, deflating developer multiples
- A hyperscaler capex air-pocket or AI-spend digestion that reprices the entire power-demand narrative
- Regulatory reversal on behind-the-meter colocation (FERC) severing the direct nuclear-to-datacenter economics
- Pre-revenue developers (NNE, SMR, OKLO) burning through cash and diluting shareholders before any project reaches FID
Catalysts to watch
- H2 2026NRC review milestones for Oklo Aurora and NANO Nuclear designs
Any licensing progress or setback is the dominant binary driver for developer valuations.
- 2026FERC ruling on behind-the-meter / colocation load rules
Determines whether hyperscalers can plug directly into nuclear at the premium the sector is priced on.
- Ongoing through 2026New hyperscaler nuclear PPA / restart announcements (CEG, VST)
Each fresh long-dated contract re-rates operator cash-flow durability and pricing power.
- Q3 2026Q2/Q3 2026 earnings — operator FCF vs. developer cash burn
Widens the fundamental gap between cash-generative utilities and optionality names.
Verdict
Buy the barbell, not the basket. Accumulate the cash-generative operators — CEG and VST — into their derating as the highest-conviction way to own AI-driven power scarcity, and hold a small, deliberately sized book of SMR optionality (OKLO, NNE) for the developer upside while treating NuScale as a hold until it proves it's a business. This is a structural multi-year long that just handed you a better entry; add on regulatory-driven weakness, don't chase strength.
