TL;DR
The physical fundamentals of nuclear's comeback keep strengthening — uranium term prices hit all-time highs and hyperscaler demand remains signed — but the equity complex is in a full-blown sentiment unwind, with every core name deep in drawdown and developers diluting into weakness. The market is no longer paying for political signals or non-binding frameworks; it wants signed PPAs and funded builds. The nearest binaries: FERC's ruling on Oklo's PJM complaint and a definitive TVA/ENTRA1 PPA for NuScale by year-end.
The Equity Unwind: Policy No Longer Moves the Tape
The nuclear equity complex is pricing execution risk, not demand — and even good political news can't buy a durable rally. When the House passed the Ratepayer Protection Act 417-3 on September 16, Oklo jumped 13% and NuScale 10% the next day; by September 18 the entire move had retraced. As 24/7 Wall St. put it:
"A single House vote sent nuclear stocks surging Thursday, but Friday's trading tells a very different story about how durable that enthusiasm really was." — Nuclear Stocks Hand Back the Vote Rally
The drawdowns are severe across the board: NuScale down 84.5% from its 52-week high, Oklo down 78.2%, Nano Nuclear down 72.2%, Cameco down 31.7% — and even regulated-utility Southern Company is off 12.3% (market views, Sept 21). The most telling signal of the AI-power premium unwinding is Holtec shelving its ~$900M IPO — the biggest nuclear IPO in years — explicitly tied to AI-trade sentiment (Reuters). With the 10-year Treasury at 4.94%, the rate backdrop is hostile to long-duration, pre-revenue stories (macro view).
What to watch: Whether the Oklo $1B and NuScale $750M dilution programs get consumed at these depressed levels — that is the marginal price of SMR capital right now (Oklo market view).
The Ratepayer Protection Act: A Real Tailwind, But the Senate Is the Gate
The political economy of data-center power is hardening in nuclear's favor — data centers are being told to pay their own way, which structurally favors dedicated generation deals. H.R. 9340 requires regulators to ensure cost recovery for the "full, incremental" cost of grid upgrades serving large loads, with a 100 MW threshold, and codifies the White House pledge signed by Amazon, Google, Meta, Microsoft, OpenAI, Oracle and xAI (Utility Dive). The logic for SMRs is direct, as FinanceFeeds noted:
"A data center facing the full cost of grid upgrades has a stronger reason to buy dedicated generation, and small modular reactor firms sell exactly that." — FinanceFeeds
But ClearView Energy Partners thinks the bill is "unlikely to pass the Senate before midterm elections in November," and warns that forcing data centers to bring their own new capacity "could extend the construction process of data centers by years" (Utility Dive). Meanwhile the political backlash is visible at the state level: Georgia's PSC — Southern Company's regulators — met in Savannah for the first time in over a century to face public criticism over data centers and rising bills, and Morgan Stanley cut Southern to Underweight (Southern market view).
What to watch: Senate action on H.R. 9340 — pre-election passage likely requires unanimous consent, leaving room for a block.
Uranium: Record Term Prices, Decoupled Equities
The uranium market is signaling structural deficit even as uranium equities sell off — the metal and the miners have decoupled. The long-term contract price closed August at $96.50/lb, above its 2007 peak and an all-time high (Crux Investor), while spot sits at $89.70/lb, up 16.65% year over year (Trading Economics). The ~$7/lb spot-term spread reflects utilities paying up for security of supply rather than chasing spot pounds.
Cameco is the sharpest expression of the divergence: a Q2 EPS of $0.13 against $0.26 consensus, earnings down 92.1% year over year, and the stock 31.7% off its high (Cameco market view). Yet institutions are buying the dip — Bank of America took a new 7.22M-share stake worth ~$735.5M, and Jefferies initiated at Buy with a C$190 target "citing strong demand for nuclear power" (Cameco market view).
What to watch: The unresolved Section 232 uranium import negotiations, past their July 13 deadline — any tariff or minimum-import-price outcome would directly benefit Western producers like Cameco.
NuScale and Oklo: The Binary Catalysts
Both flagship SMR developers are now diluting shareholders at 52-week lows while their defining catalysts remain unsigned. NuScale launched a $750M ATM in August with TTM revenue down 99.1% to $10.7M, and UBS's September 11 downgrade to Sell was headlined "This Slowdown Is Hard to Ignore" (TipRanks). The whole story hinges on the TVA/ENTRA1 framework for up to 6 GW — still non-binding, and structured so that "NuScale wouldn't own a reactor in the deal driving its stock" (Motley Fool).
Oklo's story has bifurcated similarly: demand keeps compounding — the Meta-backed 1.2 GW Ohio campus, a planned HALEU deconversion JV with Centrus at Piketon "co-located with Centrus' enrichment operations and adjacent to Oklo's planned 1.2 GW power campus" (Oklo press release) — but the company just announced a $1B share sale (~14% dilution) with $141.7M of quarterly free cash flow burn (Oklo market view). The FERC docket (EL26-101) over PJM dropping Oklo's 750-MW Virginia project remains unresolved, with PJM arguing its withdrawal "was final" (PJM answer).
What to watch: FERC's ruling on EL26-101 — the nearest-term binary for whether interconnection queues can absorb mixed-technology nuclear projects.
What surprised us
- Policy rallies now round-trip within 24 hours. A 417-3 House vote used to be a multi-week repricing event for this theme; Oklo and NuScale gave back the entire move by the next session (24/7 Wall St.). The buyer base for SMR equities has thinned dramatically.
- Institutions are treating the Cameco drawdown as entry, not exit. BofA's new $735.5M stake immediately after a 50% EPS miss is the strongest signal that large money still believes in the contract-book repricing story into a $96.50/lb term market (Cameco market view).
- The Oklo-PJM fight is about more than one project. The withdrawn project is a 750-MW mixed-technology facility — reactors, fuel cells, gas — and the dispute will test whether grid operators' standard review processes can handle hybrid nuclear projects at all (ANS).
