Top 10 Nuclear Power Stocks in the US Market for 2025

As the global energy landscape shifts toward cleaner, more sustainable solutions, nuclear power is experiencing a renaissance. With increasing demand for reliable, carbon-free energy—driven by AI data centers, net-zero goals, and supportive government policies—nuclear energy stocks are gaining significant attention. The U.S. is the world’s largest producer of nuclear energy, contributing about 30.9% of global nuclear electricity, and companies in this sector are well-positioned for growth in 2025 and beyond. Below is a curated list of the top 10 nuclear power stocks in the U.S. market, selected based on their market presence, operational scale, innovation in nuclear technology, and analyst upside potential.

1. Constellation Energy Corporation (NASDAQ: CEG)

Constellation Energy is the largest nuclear power plant operator in the U.S., managing over 20 reactors across the Midwest, Mid-Atlantic, and Northeast, producing roughly 10% of the nation’s clean energy. Its scale and strategic partnerships, such as a 20-year power purchase agreement with Microsoft to restart the Three Mile Island Unit 1, position it as a leader in meeting the energy demands of AI and tech sectors. Analysts project double-digit earnings growth, with a 10% increase expected in 2025 and 20% in 2026, supported by the Nuclear Production Tax Credit and its acquisition of Calpine, expanding its natural gas and geothermal capabilities.

2. Vistra Corp. (NYSE: VST)

Vistra is one of the largest power producers in the U.S., with a diverse portfolio including 41 gigawatts of nuclear, coal, natural gas, and solar generation. Its nuclear capacity, bolstered by the 2023 acquisition of Energy Harbor, makes it a key player in the sector. Vistra’s strong liquidity, with $905 million in cash and $2.5 billion in credit availability as of Q3 2024, and an active share repurchase program enhance its appeal. The stock has been the top performer in the S&P 500 in 2024, reflecting investor confidence in its ability to capitalize on rising energy demands.

3. BWX Technologies, Inc. (NYSE: BWXT)

BWX Technologies is a leading supplier of nuclear components and fuel, serving both commercial and government clients, including naval nuclear propulsion and nuclear medicine. Its work on small modular reactors (SMRs) and microreactors, in collaboration with GE Hitachi and NASA, positions it at the forefront of nuclear innovation. Analysts expect revenue growth of 11% in 2025 and 2026, with adjusted earnings rising by 5% and 13%, respectively. Trading at a 65% discount to its highs, BWXT offers a compelling valuation for growth-oriented investors.

4. NuScale Power Corporation (NYSE: SMR)

NuScale Power is a pioneer in small modular reactor (SMR) technology, offering scalable, cost-effective, and safer nuclear solutions. Its SMRs, the only ones with a Standard Design Approval from the U.S. Nuclear Regulatory Commission, are designed for rapid deployment. Despite challenges, such as the 2023 cancellation of an Idaho project due to cost overruns, NuScale’s potential deal with Romania’s RoPower for six SMRs could be a catalyst in 2025. Analysts project revenue growth from $23 million in 2023 to $193 million by 2027, making it a high-risk, high-reward pick.

5. Oklo Inc. (NYSE: OKLO)

Oklo is an emerging player developing microreactors, capable of powering remote locations and data centers with clean energy for over a decade without refueling. Backed by Sam Altman, Oklo has secured agreements with the U.S. Department of Energy and plans to bring its first reactor online by 2027. Its stock surged 23.1% following Trump’s nuclear-focused executive orders in May 2025, reflecting speculative interest. With an enterprise value of $6.2 billion, Oklo is a volatile but promising option for investors betting on next-generation nuclear technology.

6. Cameco Corporation (NYSE: CCJ)

Cameco, a Canadian company listed in the U.S., is one of the world’s largest uranium producers, supplying fuel for nuclear power plants globally. Its high-grade reserves in Canada and Kazakhstan, combined with its 2022 acquisition of a majority stake in Westinghouse (a leading U.S. nuclear plant builder), give it control over a significant portion of the nuclear supply chain. With uranium demand expected to rise 28% by 2030, Cameco’s stock, up nearly 45% in the past month, is a strong play on rising uranium prices and nuclear expansion.

7. Uranium Energy Corp. (NYSE American: UEC)

Uranium Energy is the largest U.S.-based uranium mining company, with projects in New Mexico, Arizona, and Wyoming. Its acquisition of Uranium One Americas and recent commissioning of the Christensen Ranch ISR mine strengthen its domestic production capacity. UEC’s stock jumped 19.6% after securing a Department of Energy contract in May 2025, reflecting its role in reducing reliance on foreign uranium. With Western nations prioritizing secure supply chains, UEC is well-positioned for growth.

8. Centrus Energy Corp. (NYSE American: LEU)

Centrus Energy specializes in enriched uranium fuel for commercial nuclear power plants and is the only U.S. company accredited to produce high-assay low-enriched uranium (HALEU) for advanced reactors. Its recent Department of Energy contract to expand HALEU production and a 21% stock surge in a single day underscore its strategic importance. As the U.S. aims to triple nuclear capacity by 2050, Centrus’s focus on fuel supply for SMRs and microreactors makes it a critical player.

9. NANO Nuclear Energy Inc. (NASDAQ: NNE)

NANO Nuclear is developing portable microreactors for applications like data centers, military bases, and space systems. Its stock soared 30% after Trump’s nuclear executive orders, driven by its innovative approach and partnerships, such as a loan agreement with TerraPower for HALEU supply. While still pre-revenue, NANO’s focus on next-generation nuclear solutions positions it as a speculative but high-potential investment for 2025.

10. GE Vernova Inc. (NYSE: GEV)

GE Vernova, a spin-off from General Electric, is a diversified clean energy company with a strong nuclear portfolio through its GE Hitachi division, which develops the BWRX-300 SMR. With permission granted in mid-2025 to build an SMR in Ontario, GE Vernova is poised to capitalize on the growing SMR market. Analysts forecast revenue growth from $1.4 billion in 2024 to $45 billion by 2028, driven by its nuclear, wind, and electrification businesses, making it a robust long-term investment.

Why Invest in Nuclear Power Stocks in 2025?

Nuclear energy is gaining momentum due to its reliability, low carbon emissions, and ability to meet the surging power demands of AI data centers and other high-consumption industries. The U.S. government’s push to triple nuclear capacity by 2050, coupled with executive orders to streamline regulations, creates a favorable environment for these companies. However, risks such as high capital costs, regulatory hurdles, and public perception challenges remain. Investors should carefully assess their risk tolerance, especially with speculative stocks like NuScale, Oklo, and NANO Nuclear.

Conclusion

The nuclear energy sector offers a compelling mix of established players like Constellation and Vistra, uranium suppliers like Cameco and Uranium Energy, and innovative disruptors like NuScale and Oklo. As the U.S. and global markets prioritize clean, reliable energy, these 10 stocks stand out for their growth potential in 2025. Always conduct thorough research and consider consulting a financial advisor before investing, as nuclear energy stocks carry unique risks alongside their opportunities.
