State of Nuclear Energy
Fission, SMR & fusion value-chain board — US-first, June 2026. AI-datacenter demand is real; the question is where the margin is durable vs. where the narrative is priced ahead of revenue.
Own the fuel-cycle and the incumbent operators; rent the SMR/fusion frontier via ETFs
The durable money in this cycle sits where the moat is structural and the cash flows are real: the enrichment/HALEU bottleneck (LEU), the diversified fuel-cycle leader (CCJ), the defense-anchored components incumbent (BWXT), and the nuclear-heavy utilities/IPPs already signing AI-datacenter PPAs (CEG, VST, TLN as reference arms) — own these. The SMR developers (OKLO ~$8.7B mcap pre-revenue, SMR/NuScale) and the entire fusion frontier (CFS, Helion, GFUZ, TAE, Tokamak, Zap) are real-option lottery tickets priced for perfection on 2028-2032 timelines that keep slipping — size them small, and for most investors rent the basket via NUKZ (renaissance/SMR) or URA/URNM/NLR rather than single-name the binaries. This is not financial advice; the fission economics are durable while a large share of the SMR/fusion narrative premium is hype that won't generate a kilowatt-hour of revenue this decade.
No single name dominates the whole chain. The closest things to franchise positions are LEU (effective US-licensed HALEU monopoly, $3.8B backlog to 2040), CCJ (largest Western fuel-cycle, ~230Mlb contract book + Westinghouse stake), and BWXT (sole-source naval reactor components, $8.65B backlog). On the operating side the diversified reference arms — CEG, VST, TLN — own the installed nuclear base that AI hyperscalers are actually contracting today. Fission incumbents dominate; SMR/fusion are contenders, not yet category-definers.
Full-stack value chain
Layers ranked by margin durability and cycle position, not by headline volume. The middle of the chain — enrichment/HALEU, fuel cycle, components — is where the moat is structural; the ends get the headlines.
The two layers generating the loudest narrative — SMR developers and fusion — are the two with the least durable near-term economics (pre-revenue, milestone-binary). The most durable margins sit quietly in the middle: enrichment/HALEU (LEU, a policy-protected US chokepoint), the integrated fuel cycle (CCJ), and defense-anchored components (BWXT). Own the bottleneck and the picks-and-shovels; rent the frontier. The fission economics are real today; a large share of the SMR/fusion premium is a bet on timelines that keep slipping.
