Nuclear Stocks in 2026: How to Invest in Nuclear Energy (Updated Weekly)
- The five segments of the nuclear trade and which tickers actually sit in each one
- Live prices on the ten names the category is searched on, refreshed weekly
- What the filings say about revenue, cash and share count, which is where these stories diverge hardest from the narrative
- The options layer: where implied volatility sits across the sector and why that matters more than picking a direction
- A trade we named publicly on OKLO that did not work, and what it taught us
Nuclear went from a stranded asset to the most crowded energy story in the market, and the reason is not sentiment. It is load growth. Datacenters need firm, always on power that a wind farm cannot promise, and nuclear is the only zero carbon source that runs at better than 90 percent capacity factor. That single fact is why hyperscalers started signing twenty year power purchase agreements with reactor operators, and why a shuttered plant on the Susquehanna River is being brought back to life.
The problem for anyone trying to trade it is that "nuclear stocks" is not one trade. It is five, and they behave nothing alike. A uranium miner and a pre revenue reactor developer respond to completely different news, carry completely different risk, and price their options completely differently. Lumping them into a single list is how people end up holding the wrong instrument at the wrong time.
The Five Segments of the Nuclear Trade
Work down the fuel cycle. Every nuclear ticker sits in exactly one of these five buckets, and knowing which bucket a name belongs to tells you more about how it will trade than any price target ever will.
Fuel and Mining
Digs uranium out of the ground and sells it under long term contracts. Revenue exists today. Moves on the uranium price and on contracting cycles.
Enrichment and Fuel Cycle
Turns raw uranium into reactor grade fuel. A separate bottleneck from mining, and the one the Russian import ban made strategic.
Reactor Developers
Designing small modular and advanced reactors. Mostly pre revenue. Funded by issuing shares, which is the single most important thing to understand about them.
Operators
Own and run reactors that are generating power and cash right now. This is where the datacenter power purchase agreements are being signed.
Components and Services
Builds the hardware and fuel for existing reactors and the naval fleet. The least speculative way to hold sector exposure.

-
OKLOOklo Inc$39.88▼ -6.32% todayMKT CAP $7.42BP/E N/A52W $37-194◎ BEST PLAY: Defined-risk debit spread · 30-45 DTEAdvanced fission developer. First revenue ever in Q2 2026 ($1.21M, engineering and consulting, no power sales) against a $48.5M quarterly loss. Roughly $3.0B liquidity, funded by heavy ATM issuance. Rich IV, wide markets: size small and define risk.
-
SMRNuScale Power$10.21▼ -5.55% todayMKT CAP $4.19BP/E N/A52W $7-57◎ BEST PLAY: Defined-risk debit spread · 30-45 DTE
The only SMR design with US regulatory approval. Q2 2026 revenue fell to $75K after the RoPower FEED work completed. About $1.9B cash, no meaningful debt, and a new $750M ATM launched August 2026. A licensing-timeline bet, not an earnings bet.
-
NNENANO Nuclear Energy$17.36▼ -4.46% todayMKT CAP $932MP/E N/A52W $15-61◎ BEST PLAY: Long calls (small size) · 21-30 DTE
The most speculative name on the board. Trailing revenue of $214K comes entirely from an acquired nuclear-logistics business, not reactors. Share count up about 88% in 26 months. Highest IV in the group: position size does the risk management here.
-
LEUCentrus Energy$165.87▼ -8.61% todayMKT CAP $3.31BP/E 87.852W $142-464◎ BEST PLAY: Debit spread · 30-45 DTE
The enrichment bottleneck, and a real revenue business: Q2 2026 revenue of $176.1M. Watch the backlog definition, $4.5B headline versus roughly $0.8B of ASC 606 performance obligations. FY27 DOE budget does not fund further HALEU cascade operation.
-
CCJCameco$97.42▼ -2.98% todayMKT CAP $42.43BP/E 168.052W $78-135◎ BEST PLAY: Covered call / debit spread · 30-45 DTE
The liquid way to own the mining side. Q2 2026 revenue of $814M and adjusted EBITDA of $391M, with 2026 production guidance reaffirmed at 19.5-21.5M lbs. Contract book supports over 28M lbs a year through 2030. Half the IV of the developers.
-
CEGConstellation Energy$285.97▼ -2.70% todayMKT CAP $101.32BP/E 28.052W $229-413◎ BEST PLAY: Covered call / debit spread · 30-45 DTE
The cash-flowing centre of the nuclear trade. Q2 2026 adjusted operating EPS of $2.55, FY guidance raised to $11.50-$12.50. Signed about 920 MW of new long-term nuclear PPAs at 18.5 years average. Deepest options chain in the sector.
-
VSTVistra$147.05▼ -2.68% todayMKT CAP $49.36BP/E 24.852W $133-220◎ BEST PLAY: Debit spread / covered call · 30-45 DTE
Independent power producer with a nuclear fleet, levered to the same datacenter load-growth story as CEG but with a different generation mix. Liquid chain, moderate IV, behaves like a utility rather than a story stock.
-
TLNTalen Energy$311.54▼ -2.54% todayMKT CAP $14.93BP/E N/A52W $289-451◎ BEST PLAY: Debit spread · 30-45 DTE
Owns Susquehanna and sits at the centre of the datacenter power thesis. Carries no meaningful P/E because trailing earnings are negative, with a TTM net loss of $185M. High share price means contract sizing needs care.
-
BWXTBWX Technologies$152.49▼ -2.69% todayMKT CAP $13.97BP/E 39.552W $148-242◎ BEST PLAY: Covered call / debit spread · 30-45 DTE
Builds naval reactors and nuclear components, and supplies fuel. The least speculative way to hold sector exposure: real revenue, government contracts, and a chart that moves on backlog rather than on headlines.
-
UUUUEnergy Fuels$13.63▼ -6.32% todayMKT CAP $3.61BP/E N/A52W $11-28◎ BEST PLAY: Long calls (small size) · 21-30 DTE
US uranium producer that also processes rare earths, which makes it a two-thesis stock. Smaller and more volatile than CCJ, and it moves hard on both uranium and critical-minerals policy news.

Reactor Developers: Read the Share Count, Not the Story
This is where the retail attention is, and it is where the filings tell the least flattering version of the story. These companies are building something real. They are also funding it by selling stock, and every share sold is a claim on the same future.
Oklo (OKLO) recorded the first revenue in company history in Q2 2026: $1.210 million, against zero in the year ago quarter. None of it was power sales. It broke down as $800 thousand of engineering and consulting, $168 thousand of manufacturing and fabrication, and $242 thousand of other. In the same quarter the company posted a net loss of $48.536 million on operating expenses of $74.400 million. It is extremely well funded: about $3.006 billion of total liquidity at June 30, 2026 between cash and marketable securities.
That funding came from somewhere. Oklo issued 23,088,406 shares through at the market programs in the first half of 2026 alone, raising $1.880 billion gross at an average net price of $81.44. Share count reached 186,017,650 Class A shares as of August 4, 2026, against a weighted average of 140,085,498 in Q2 2025. The 2025 program sold at an average of $96.95 and the 2026 program at $63.51, which tells you the company sold stock into strength and kept selling as the price came down.
NuScale Power (SMR) is the only small modular reactor design with US regulatory approval, and its revenue went the other direction. Q2 2026 revenue was $75 thousand, down $8.0 million year over year, after Fluor completed FEED Phase 2 work for the RoPower project in Romania in late 2025. First half revenue was $640 thousand against $21.4 million a year earlier. The company ended the quarter with roughly $1.9 billion in cash and investments and essentially no debt, and Class A shares outstanding rose to 410.4 million from 318.5 million at year end 2025. On August 11, 2026 it launched a new at the market program to sell up to $750 million more.
NANO Nuclear (NNE) is the most speculative of the three. Trailing twelve month revenue is $214,042, generated entirely by Secured Transportation Services, a nuclear logistics business it acquired in May 2026. The reactor business has produced nothing. It holds roughly $580 million in cash and short term investments. Share count went from 28,569,513 in June 2024 to 53,698,146 by August 2026, an increase of about 88 percent in roughly 26 months.
Lightbridge (LTBR) is pre revenue with $0 in sales, a first half 2026 net loss of $12.1 million, and share count up about 160 percent in 26 months, from 14,434,480 to 37,458,091.
Operators: The Part of Nuclear That Already Makes Money
If the developers are a bet on reactors that do not exist yet, the operators are a bet on reactors running today at rising power prices. Constellation Energy (CEG) reported Q2 2026 adjusted operating earnings of $2.55 per share, up from $1.91 a year earlier, and raised full year guidance to $11.50 to $12.50 per share. It signed roughly 920 megawatts of new long term nuclear power purchase agreements in the quarter, at an average duration of 18.5 years.
Constellation also completed its acquisition of Calpine on January 7, 2026, paying 50 million newly issued shares plus $4.5 billion in cash, creating a combined portfolio of roughly 55 gigawatts. And it is restarting Three Mile Island Unit 1 as the Crane Clean Energy Center, restoring about 835 megawatts under a twenty year agreement with Microsoft. That restart is now expected as early as 2027, ahead of the original 2028 target, with a license extension being pursued to at least 2054.
Vistra (VST) and Talen (TLN) are the other two ways to own this. Talen is worth a caution: it carries no meaningful price to earnings ratio because trailing earnings are negative, with a trailing twelve month net loss of $185 million. A stock can be a fine business story and still be an awkward options underlying when the earnings line is negative.
Uranium and Enrichment: The Bottleneck Nobody Sees
Uranium is not exchange traded the way equities are. Roughly 85 percent of volume moves through privately negotiated long term contracts, so every price you see quoted is a consultant assessment, not a settlement. Cameco published an industry monthly average spot price of $89.68 per pound for August 2026, with a long term price of $96.50. Different indices differ by a few dollars, so always check which one a number came from.
The structural story is contracting, not spot. Roughly 37 million pounds had been contracted globally in 2026 as of mid August, putting the market on track for a fourteenth consecutive year of below replacement contracting. Kazakhstan supplies 39 percent of global production, and US domestic production accounted for only 7 percent of US utility deliveries in 2025. That concentration is the reason enrichment became a policy priority.
Cameco (CCJ) is the liquid way to own the mining side. It reported Q2 2026 revenue of $814 million, adjusted EBITDA of $391 million, and reaffirmed 2026 production guidance of 19.5 to 21.5 million pounds despite unplanned disruptions at Key Lake, McArthur River and Cigar Lake. Its long term contract book supports average deliveries of over 28 million pounds a year through 2030. One thing to watch: its share of Westinghouse swung to a $10 million net loss in Q2 2026 from $126 million of earnings a year earlier, largely on the Czech Dukovany project.
Centrus Energy (LEU) is the enrichment play, and it comes with the single most misread number in the sector. Centrus reports backlog of $4.5 billion extending to 2040. Its remaining performance obligations under ASC 606, which is the stricter accounting measure of contracted work, were approximately $0.8 billion as of June 30, 2026. The gap is not fraud, it is definitional: about $3.0 billion of the LEU segment backlog is contingent commitments, of which $2.4 billion sit under definitive agreements. Anyone quoting the $4.5 billion figure without that context is quoting a headline, not an obligation.
What the Options Market Is Actually Charging
Here is the part a stock listicle cannot give you. On September 4, 2026 the sector split into two clean volatility tiers, and the split maps exactly onto the segment map above.
| Ticker | Segment | 30-day IV | 3-month median IV |
|---|---|---|---|
| NNE | Developer | 74.8% | 100.4% |
| SMR | Developer | 73.5% | 98.2% |
| OKLO | Developer | 72.6% | 89.9% |
| LEU | Enrichment | 68.2% | 85.7% |
| CCJ | Mining | 44.8% | Lower tier |
| CEG | Operator | 42.4% | Lower tier |
Two readings come out of that table. First, the developers and the enricher carry 68 to 75 percent implied volatility while the miner and the operator carry 42 to 45 percent. You are being charged roughly 1.7 times as much, in volatility terms, to express a view on a company with no revenue. That is the market pricing exactly the risk the filings describe.
Second, and less obvious: every one of those six names sat in the bottom quarter of its own trailing three month implied volatility range on that date. The small caps in particular were far below their own medians. Volatility compressing after a large drawdown is a genuine structural condition, and it changes which instrument makes sense. When implied volatility is cheap relative to its own recent history, defined risk debit structures cost less to put on than they did. When it is rich, selling premium is compensated better. Neither is a directional call.
The OKLO Trade We Named, and Why It Failed
In May 2026 we published an alert on OKLO: a May 6 call at the $110 strike, entered at $5.15. It reached a maximum opportunity of about 17 percent and we graded it a Miss. In the same published cohort, a QCOM alert ran to more than 1,500 percent. We publish both, because a track record with the losses removed is not a track record.
The lesson was structural rather than directional. OKLO was a breakout that failed, and the position was a long call with a fixed expiry, which means the thesis needed to be right about direction and about timing, in a name whose implied volatility was near the top of its range at entry. Buying a rich option on a pre revenue developer requires the move to be big enough and fast enough to beat both the decay and the volatility coming back down. It was neither.
That is the trade this page exists to help you avoid repeating. The full case study on that OKLO breakout is here.
How to Invest in Nuclear Energy Without Guessing
Three questions, in order, before any nuclear position:
1. Which segment am I actually buying? Look it up on the map above. If it is a developer, you are buying a license timeline funded by share issuance. If it is an operator, you are buying contracted electricity. The news that moves one barely touches the other.
2. What does the latest 10-Q cover page say about share count? For anything in segment 3 this is the number that matters most, and it is free to check. A company that grew its share count 88 percent in 26 months is telling you how it intends to keep the lights on.
3. What is implied volatility doing relative to its own history? Not whether it is high in absolute terms, but where it sits in its own recent range. That determines whether you are better served buying a defined risk spread or selling premium, and it is the question almost nobody asks before clicking buy. You can work the numbers on any of these tickers with our options profit calculator.
For broader exposure without single name risk, sector ETFs exist and spread the license timeline risk across many holdings. That is a different trade with a different risk profile, and it will not deliver the moves that draw people to this sector in the first place.

Frequently Asked Questions
What are the best nuclear stocks to buy right now?
We do not publish buy calls, and any site that names one without knowing your timeline or risk tolerance is guessing on your behalf. The more useful framing is segment fit. If you want revenue and dividends today, that lives in operators and miners like CEG, VST and CCJ. If you want exposure to reactor deployment and can accept pre revenue risk plus ongoing share issuance, that is OKLO, SMR and NNE. The segment map above is built to make that choice explicit.
Why is Oklo stock dropping?
Two mechanical reasons show up in the filings rather than the headlines. Oklo has been funding itself through at the market share sales, issuing 23,088,406 shares in the first half of 2026 alone, which increases the claim count on the same future. And its first ever revenue, $1.210 million in Q2 2026, was engineering and consulting work rather than power sales, against a $48.536 million quarterly net loss. When a stock has run a long way ahead of its filings, any gap between the two tends to close through the price.
Is Oklo or NuScale the better small modular reactor stock?
They are not the same bet. NuScale has the only small modular reactor design with US regulatory approval, but its revenue fell to $75 thousand in Q2 2026 after the RoPower FEED work completed, and it launched a $750 million at the market program in August 2026. Oklo has more liquidity, about $3.0 billion, a different reactor concept and a different customer model. Both are pre revenue in any meaningful sense and both fund themselves by issuing stock. The comparison that matters is license timeline against cash runway against dilution rate, and all three are in the filings.
Are uranium stocks the same trade as nuclear stocks?
No, and the two have diverged sharply. As of July 31, 2026, uranium mining equities were down 10.82 percent year to date and junior miners down 13.33 percent, while U3O8 spot was up 5.96 percent. The commodity going up does not automatically carry the equities with it, because miners carry operational risk, contract timing and cost inflation that the raw material does not.
Which nuclear stocks have the most liquid options?
Broadly, the larger and older the company, the deeper the chain. CEG and CCJ carry the most institutional participation and the tightest spreads of the names on this page. The developers have active chains but noticeably wider markets and much higher implied volatility, which means the cost of being wrong is larger even when the position size looks identical.
When do the nuclear companies next report earnings?
As of September 8, 2026, Q3 dates had not been formally announced for OKLO, SMR, LEU or CEG. Their prior year Q3 filings landed on November 6, 2025 for SMR and LEU, November 7 for CEG and November 12 for OKLO, which puts the November 20, 2026 monthly expiry as the first listed expiry likely to contain Q3 results for OKLO, SMR and CEG. Cameco lists an upcoming investor item dated October 30, 2026. Confirm against each company's investor relations page before trading an earnings expiry.
