Top Nuclear Stocks For October 2026
Europe’s power demand is climbing again as electric vehicles, air conditioning and data centers lean harder on the grid, which puts long term electricity supply in the spotlight. That kind of pressure can focus attention on nuclear energy stocks that aim to provide round the clock, low carbon power. This article walks through three nuclear focused companies from our screener that many investors are watching right now.
The three stocks highlighted here offer a compelling starting point if you want exposure to nuclear energy producers, enrichment providers and reactor operators delivering reliable low carbon power. However, if you want the standouts, these 16 nuclear renaissance stocks are the most outstanding.
NuScale Power (SMR)
NuScale Power is one of the purest plays in the Nuclear Energy Stocks screener. Its small modular reactor technology targets utilities that want grid scale, low carbon baseload power without committing to a full size nuclear plant from day one.
NuScale Power develops and supports its 77 MWe NuScale Power Module small modular reactors for electric utilities. It earns about US$11 million from electric utility services and related support in the United States, and the business is valued at roughly US$2.5b by the market.
For investors focused on nuclear buildout, NuScale Power ties into the theme through its licensed small modular reactors and a broad suite of lifecycle services that span design, licensing, construction and long term operations for utilities and industrial customers.
"NuScale's involvement in the RoPower 6-module small modular reactor (SMR) power plant in Romania indicates future meaningful revenue and cash flow through its partnership in the Fluor-led Front-End Engineering and Design (FEED) Phase 2."
What matters next is how one unresolved piece of the commercial puzzle ultimately shapes NuScale Power's growth path and potential margins.
That unresolved piece is exactly what the full full narrative for NuScale Power unpacks, explaining how NuScale Power’s commercial path could either accelerate or stall as contracts and costs become clearer.
Constellation Energy (CEG)
Constellation Energy runs a large fleet of generation assets in the United States, with nuclear plants providing round-the-clock, carbon-free baseload power that aligns directly with the Nuclear Energy Stocks theme. Nearly all of its revenue, about US$31.3b, comes from its Generation segment, and the company is valued at roughly US$96.1b.
Constellation Energy matters here because it couples one of the largest nuclear fleets in the country with customers that increasingly want reliable, low-carbon electricity on multi-decade terms, which is exactly where this theme becomes more tangible.
"Growing demand for carbon-free, reliable power from large-scale customers such as data centers and large corporates is now translating into roughly 920 MW of long-duration nuclear power contracts with investment-grade buyers on an average 18.5-year term. These contracts can support more visible revenue and earnings for Constellation Energy as additional load is signed over time."
A key consideration for Constellation Energy is how one evolving source of demand ultimately influences pricing power and long-term profit margins.
That pricing question is exactly what the full full narrative for Constellation Energy unpacks, revealing how data center demand, contract mix and policy could accelerate or cap earnings power for Constellation Energy.
Oklo (OKLO)
Oklo focuses on its Aurora Powerhouse small modular reactors that aim to provide on site nuclear electricity between 15 and 75 megawatts, along with fuel recycling and fabrication that can turn used nuclear material into fresh fuel. The business is valued at about US$5.2b.
Oklo plugs into the Nuclear Energy Stocks theme through compact fission plants and fuel recycling that both target reliable, low carbon power for industrial and data center customers. The next step in that story hinges on a key regulatory milestone.
"Just had a major regulatory hurdle overcome, NRC (Nuclear Regulatory Commission) just approved Oklo’s Principal Design Criteria for Aurora. Reactors still aren’t fully licensed / approved, but this has a significant positive impact on uncertainty."
What really matters from here is how one long term funding and commercialization test reshapes the odds that Oklo’s nuclear projects reach scale.
That funding test is exactly where the full full narrative for Oklo steps in, mapping how capital, regulation and partnerships could turn Oklo’s Aurora concept into accelerating deployment.
