Nuclear energy stocks have posted extraordinary gains, fueled by soaring demand for AI-driven power and supportive government policies. Small modular reactors (SMRs) promise flexibility, but they face hurdles including long lead times, cost risks, and licensing challenges. Investors are advised to focus on key milestones such as binding contracts, regulatory approvals, and credible project financing.
A Surge in Nuclear Sector Interest
Jacob Falkencrone, Chief Investment Strategist at Saxo, notes that nuclear energy stocks have rarely risen as sharply as they are now. Oklo’s shares soared more than 1,000% in the past year, including a stunning 63% jump last week. NuScale gained 26%, while Nano Nuclear climbed nearly 40%. Uranium producers also advanced, with Cameco and Uranium Energy each rising over 10%.
The drivers are clear: Washington and London announced new nuclear cooperation, the White House accelerated licensing and fuel security efforts, and the U.S. Department of Energy launched new pilot programs. This rare combination of political backing and technological momentum has electrified the market.
Yet some players are cashing in. Oklo’s CFO filed to sell $9 million worth of shares, while Fluor, NuScale’s largest shareholder, trimmed its stake. This suggests valuations may be running ahead of construction timelines.
Why AI Has Revived Nuclear Interest
Nuclear’s resurgence isn’t ideological—it’s physical. AI consumes electricity at a pace grids were never designed to handle. The International Energy Agency estimates that by 2030, global data centers could use as much power as an entire country like Japan. That equates to adding the annual demand of New York City every year.
Renewables alone cannot shoulder this load. Nuclear offers something unique: carbon-free, 24/7 baseload power with uptime above 90%, far surpassing wind, solar, or gas.
Tech giants are responding. Google agreed to source nuclear power for AI workloads, Microsoft is weighing reopening shuttered U.S. nuclear plants, and Meta partnered with Constellation. While still pilot projects, they highlight growing ties between Silicon Valley and the nuclear industry.
“AI has made nuclear power relevant again—it’s one of the few sources that can run continuously, 24/7, for decades,” says Falkencrone.
The Promise—and Peril—of SMRs
Much of the excitement centers on small modular reactors and microreactors—compact units built in factories and shipped by truck rather than constructed onsite over many years. Dozens of U.S. and European startups are pursuing them, while China is already deploying its first units.
The idea is compelling: lower costs, faster builds, and flexible siting. But profitability remains unproven. No SMR has yet been completed in the U.S., and pioneer projects often blow past budgets and schedules. Licensing remains slow, advanced fuel supply chains are incomplete, and without binding offtake agreements, financing is nearly impossible.
A Narrow but Growing Investment Space
Scarcity is the sector’s hidden asset. Currently, only three pure-play nuclear developers trade publicly in the U.S.—Oklo, NuScale, and Nano Nuclear—and their limited availability has boosted investor demand. All three listed via SPAC mergers, a vehicle that disappointed in many sectors but delivered outsized returns in nuclear.
Now more are lining up. Terra Innovatum, Terrestrial Energy, and Eagle Energy Metals are preparing SPAC listings this year. Their approaches vary—miniature modules, molten salt tech, hybrid mining-development models—but all remain far from commercial launch.
For risk-averse investors, alternatives exist. Regulated utilities extending the life of existing plants provide steadier cash flows. Uranium miners and enrichment firms benefit from efforts to reduce reliance on Russian supply. Engineering and component suppliers could also emerge as “winners” in nuclear infrastructure buildouts.
Risks Investors Cannot Ignore
Despite vast potential, nuclear carries serious risks:
- Construction risk: Average costs exceed budgets by over 100%, and delays are common.
- Regulatory risk: Approvals remain slow, and political winds can shift quickly.
- Community opposition: Local resistance has derailed projects before.
- Supply chain fragility: Uranium enrichment remains heavily dependent on Russia.
- Market psychology: Gains have been fueled by optimism and hype; insider selling suggests caution even from industry leaders.
What to Watch Next
Investors should seek tangible proof, not just press releases: binding power purchase agreements with disclosed prices and terms, regulatory progress on certifications and siting permits, secured advanced fuel supply chains, credible financing packages, and evidence that subsequent units can be delivered faster and cheaper than the first.
The calendar is filling fast. The U.S. Department of Energy will soon announce pilot program awards. Legislatures in Illinois and New York are debating lifting moratoriums on new nuclear plants. Several nuclear SPACs face shareholder votes. And the start of the first credible SMR build in North America could shift sentiment dramatically.
How Investors Should View the Opportunity
The nuclear rally is powered by three converging forces: AI’s massive electricity appetite, supportive U.S.–UK policy, and limited investable options. But hype often runs ahead of reality.
“For investors, balance is key. Uranium producers and regulated utilities offer steadier, lower-risk exposure. SMR developers and new SPACs are higher risk, potentially lucrative but volatile. The wisest approach is to track core milestones and treat nuclear as a long-term story, not a quick trade,” Falkencrone concludes.
