Key Points

Invest in fusion energy for clean, always-on power without environmental risks.
Major tech and energy firms like Alphabet and Chevron are backing fusion start-ups.
Fusion energy could hit commercial markets by the 2030s, with Helion leading early attempts.

Fusion energy stocks are publicly traded companies that are investing in fusion energy. Fusion energy is a powerful force. It's the same process that the sun and other stars use to make energy. If we could harness the power of fusion energy for commercial applications, it would be a truly groundbreaking achievement. Fusion could provide a nearly limitless source of continual clean energy. Even better, fusion energy doesn't come with the safety concerns of nuclear power, the environmental issues of fossil fuels, or the intermittency problems of renewable energy.

Technology titan Alphabet's (GOOG +0.47%)(GOOGL +0.49%) search arm, Google, has partnered with TAE Technologies for more than a decade to help develop fusion energy to power its artificial intelligence (AI) and computing power needs one day. The nuclear fusion start-up has a bold goal to develop a commercial-scale fusion reactor that can deliver energy to the grid by the early 2030s. Google subsequently invested directly in TAE Technologies in 2022 to provide it with capital to help commercialize its fusion energy technology. It also invested directly in Commonwealth Fusion Systems in 2021. It deepened its relationship with Commonwealth in 2025 by increasing its stake in the company and signing a power purchase agreement to buy 200 megawatts of electricity from its first ARC power plant in Virginia, which should start producing in the early 2030s.

Global oil and gas giant Chevron (CVX +1.16%) has been slowly investing in the future of energy. The company formed Chevron Technology Ventures (CTV) to invest in new technologies that could enhance the company's operations. In 2020, CTV invested in Zap Energy, which is developing a next-generation nuclear reactor with an innovative approach to advance commercially scalable fusion energy. The oil company followed that up in 2022 by joining Google and investing in nuclear fusion start-up TAE Technologies. Both companies provided additional capital to TAE in 2025.

Steelmaker Nucor (NUE -2.83%) unveiled a collaboration with nuclear fusion start-up Helion in 2023. Helion plans to develop a 500-megawatt fusion power plant to supply zero-carbon electricity from fusion directly to a Nucor steel plant. They're working to get the plant online as soon as possible, with a target of 2030. Nucor made a $35 million direct investment into Helion as part of the partnership to help accelerate the deployment of fusion energy.

Technology giant Microsoft hasn't made a direct equity investment in fusion energy. However, it was the first company to agree to buy fusion power from Helion Energy's inaugural plant, which it expects will come online in 2028. The 50-megawatt contract will enable Helion to commercialize the project, which will help meet Microsoft's almost insatiable demand for energy to power its AI and cloud computing operations. It could be the first of many agreements Microsoft signs to buy fusion power to support its clean energy needs.

Italian energy company Eni (E +2.43%) has invested $50 million into Commonwealth Fusion Systems (CFS), a spinoff of the Massachusetts Institute of Technology (MIT). The companies are collaborating to help accelerate the industrial development of CFS' magnetic confinement fusion technology. CFS has already reached a key milestone in developing its technology, putting it in a solid position to develop the first plant capable of producing fusion energy and feeding it to the power grid.

A very promising technology

Fusion energy could be the silver-bullet technology that enables the world to produce enough power to meet its growing needs without causing any additional harm to the environment. While many companies are working on fusion energy, the promising power technology isn't yet at the stage where it can produce commercially viable electricity for the grid. It will require continued investment to reach that point, which could be many years away. So, while the technology holds immense promise, it can't fuel returns for investors in the near term. In the meantime, investors can consider companies that have invested in the sector in hopes they find the key to unlocking the immense potential of this promising energy source.
