In a time when investors are looking to diversify their portfolios into tech, AI, and crypto stocks, nuclear energy stocks are also contenders. Nuclear energy is emerging as a critical solution due to a surge in global energy demand. There is also an ongoing search for cleaner available alternatives in energy, with nuclear energy seen as a reliable and larger-quantity alternative. Experts believe that nuclear power could bridge the supply-demand gap and drive the transition to a greener future, meaning solid profits for early stock investors.
The global nuclear power market was valued at $38.84 billion in 2024 and is projected to reach $44.71 billion by 2029. This projected growth is fueled by significant investments, including $7 billion in nuclear fusion in 2024. Additionally, the International Atomic Energy Agency (IAEA) forecasts a potential 2.5x increase in global nuclear capacity by 2050, highlighting its importance as energy demand rises.
With that being said, here are some of the best nuclear energy-focused stock options in 2025.
3 Nuclear Energy Stocks to Buy Now
Constellation Energy (CEG)
Constellation Energy (CEG) is the largest nuclear power plant operator in the United States. It produces about 10% of the nation’s total clean energy. The company is crucial for providing stable, carbon-free electricity in the US.
In the past year, CEG stock is up 140% and 28% already YTD. Looking ahead, Constellation is investing in expanding its nuclear energy capacity to meet the growing energy needs. The company plans to upgrade its existing plants, potentially adding up to one gigawatt of new clean energy capacity over the next decade. Additionally, it is exploring next-generation nuclear technologies, which could enhance efficiency and sustainability.

Dominion Energy (D)
Dominion Energy Inc (D) is another top provider in the US nuclear power sector. Its portfolio includes key nuclear assets like North Anna and Surry in Virginia, as well as VC Summer in South Carolina. Dominion has been operating for over 50 years, making it a favorable and reliable option for investment in the nuclear energy stock field.
Dominion is up 2% YTD and nearly 21% in the past year. The company is actively investing in the future of nuclear energy, particularly through the exploration of Small Modular Reactor (SMR) technology. As AI-driven data centers rapidly increase electricity consumption, Dominion’s nuclear power assets offer a scalable, around-the-clock, zero-carbon solution to support this surge in demand. The company is also in discussions with other major energy consumers to expand SMR adoption, further positioning itself as a key enabler of next-generation nuclear energy solutions.
NexGen Energy
Unlike Dominion and Constellation, NextGen Energy is based out of Canada. With nuclear energy gaining traction as a reliable and low-carbon power source, NexGen is well-placed to meet rising demand. Its flagship Rook I Project in Saskatchewan is the largest development-stage uranium deposit in Canada. Rook I is also positioned to become the world’s most cost-efficient uranium mine.

NexGen’s Arrow Deposit within Rook I is projected to produce nearly 30 million pounds of uranium per year, around 25% of today’s global supply. This output could triple Canada’s uranium production, elevating NexGen to a dominant position in the nuclear fuel market. Investors who are looking to buy in on a potentially dominant nuclear stock should look at NexGen as a considerable option.
