Nuclear Energy Stocks Retail Investors Are Watching For AI Power Demand

With oil prices held up by risks around the Strait of Hormuz, energy security is again front of mind for policymakers and investors. Reliable baseload power starts to look more valuable when fuel supplies look fragile. That is where nuclear energy stocks come in, offering exposure to companies tied to uranium, enrichment and reactors. This article highlights 3 nuclear energy stocks from our screener that stand out at the moment.

The three nuclear energy stocks covered below are only a starting sample, and the full screen surfaced 298 more companies with narratives that are just as compelling but not covered in this article. To go deeper into this theme, head straight to the Nuclear Energy Stocks screener to identify, filter and analyze the nuclear energy opportunities that best fit your portfolio.

NANO Nuclear Energy (NNE)

Overview: NANO Nuclear Energy is a New York based nuclear energy company developing several microreactor concepts, including the 15 megawatt KRONOS MMR for baseload power, the compact LOKI MMR for remote sites, the ZEUS solid core battery reactor and the ODIN low pressure salt coolant reactor. The company is also planning a high assay low enriched uranium fuel processing and transport business.

Market Cap: $1.0 billion

NANO Nuclear Energy provides targeted exposure to microreactors at a time when AI data centers, industrial users and governments are all looking for firm, low carbon power located close to demand. Progress on the KRONOS MMR prototype at the University of Illinois and recent U.S. Air Force SBIR funding indicate the technology is moving from concept toward potential deployment. The company’s push into enrichment, TRISO fuel and transport is aimed at securing a full fuel cycle. At the same time, NANO remains pre revenue, reports ongoing losses and relies on higher risk funding sources, so the high growth outlook is paired with execution, regulatory and dilution risks that investors need to weigh carefully.

Microreactors, enrichment plans and pre revenue losses make NANO Nuclear Energy a complex story that many investors only see in headline form. Read the 1 key reward and 5 important warning signs (2 are major!) and see what might be hiding in plain sight

Duke Energy (DUK)

Overview: Duke Energy is a large US regulated utility that generates and delivers electricity and natural gas through its Electric Utilities and Infrastructure segment and its Gas Utilities and Infrastructure segment, serving customers across the Southeast and Midwest. Its power mix includes coal, natural gas, oil, renewables and one of the largest regulated nuclear fleets in the country, along with gas distribution, pipelines and storage.

Operations: Duke Energy generates most of its roughly US$33.0b in revenue from Electric Utilities and Infrastructure at about US$30.2b, with Gas Utilities and Infrastructure contributing about US$3.2b, almost all from within the United States.

Market Cap: US$97.3b

Investors looking at nuclear energy as part of the grid backbone may find Duke Energy interesting because it combines a large regulated nuclear fleet with a growing queue of long term data center power contracts. Recent updates in 2026 highlight plans for significant capital investment in grid upgrades and generation, including nuclear uprates. Earnings growth expectations remain in the single digits, with a P/E below the US utilities average and a 3.52% dividend yield. That comes with meaningful trade offs. High external borrowing, upcoming equity issuance of about US$10b and exposure to natural gas and coal create funding and transition risks. The full story sits in how these growth projects, regulatory decisions and funding plans interact over the next few years.

Duke Energy’s steady nuclear backbone and data center demand story can look straightforward, yet the real twist may lie in how growth, funding plans and regulation fit together in the analysis report for Duke Energy

Fluor (FLR)

Overview: Fluor provides engineering, procurement, construction and project management services across energy, infrastructure, advanced manufacturing and government contracts, with a growing focus on nuclear power, low carbon projects and complex mission support work. The company also runs a staffing arm that supplies technical and craft workers on contract and permanent placements.

Operations: Fluor generates most of its roughly US$15.5b in revenue from Urban Solutions at about US$10.3b, with Energy Solutions and Mission Solutions contributing about US$2.6b each.

Market Cap: US$7.6b

Fluor offers exposure to large scale energy transition and infrastructure projects, as well as nuclear services for governments and commercial clients. It trades on a low P/S compared with construction peers. Expectations for the business include a shift toward profitability over the next few years, with factors such as a sizeable backlog, recent contract wins such as Aramco’s global capital projects program, and an active buyback that has already reduced the share count. On the other hand, the company is currently loss making, relies on higher risk external funding and has a relatively new management team. Execution and cash flow are therefore key considerations for anyone looking at Fluor today.

Fluor’s push toward profitability, a sizeable backlog and recent contract wins hint at a story investors may be underestimating. Learn how the analyst forecasts for Fluor aligns with its risks, cash flow swing factors and potential upcoming developments.
