For years, nuclear energy was widely viewed as a declining industry. High costs, safety concerns, and the rapid growth of renewable energy pushed many governments and investors away from the sector. Several nuclear plants were shut down, uranium prices remained under pressure, and investment slowed. Then artificial intelligence changed the equation. AI data centers require enormous amounts of electricity that must be available around the clock, something solar and wind alone cannot consistently provide. As electricity demand surges, nuclear power is once again becoming a strategic part of the energy mix. Old reactors are being extended, new projects are gaining support, and companies across the nuclear value chain are attracting renewed investor interest. Watch the video below to understand why AI is driving a nuclear revival and which companies are positioned to benefit the most.
One of the biggest beneficiaries is Constellation Energy, which operates one of the largest nuclear power fleets in the United States. Unlike many clean-energy companies that are still developing future projects, Constellation already owns operating assets capable of delivering reliable, carbon-free electricity. This has become increasingly valuable as hyperscale AI data centers demand uninterrupted power. The company’s strong operating performance, high nuclear plant utilization, and long-term power agreements have strengthened its position as a critical supplier of electricity for the AI economy. A major milestone came through its long-term agreement with Microsoft to restart the Crane Clean Energy Center, highlighting how technology companies are actively securing dependable energy sources for future AI workloads.
Reliable electricity also depends on a stable nuclear fuel supply, which brings attention to Cameco and Centrus Energy. Cameco is one of the world’s largest uranium producers and has benefited from higher uranium prices and the growing use of long-term supply contracts as utilities prepare for rising nuclear demand. Its investment in Westinghouse also provides exposure to reactor servicing and life-extension projects. Centrus operates even deeper within the supply chain by specializing in uranium enrichment, one of the most critical bottlenecks in the industry. As the United States works to reduce dependence on foreign enrichment capacity, Centrus has emerged as a strategically important company supported by government initiatives to expand domestic production. Together, these businesses represent different stages of the nuclear fuel cycle, from mining uranium to preparing it for advanced reactors.
The final piece of the story is NuScale Power, which represents a long-term investment in the future of nuclear technology. Rather than operating existing reactors, NuScale is developing Small Modular Reactors (SMRs), designed to provide flexible and scalable nuclear power for industries such as AI data centers, semiconductor manufacturing, and advanced industrial facilities. Although the company remains in the early stages of commercialization, it has achieved important regulatory milestones and built a strong cash position to support future development. Unlike Constellation, Cameco, or Centrus, NuScale’s valuation is based largely on future potential rather than current earnings.
Together, these four companies illustrate the different layers of the nuclear ecosystem. Constellation supplies electricity, Cameco provides uranium fuel, Centrus controls a critical enrichment process, and NuScale is developing the next generation of nuclear technology. As AI continues to increase electricity demand, reliable power is becoming one of the world’s most valuable resources. While software and semiconductor companies remain at the center of the AI narrative, the infrastructure required to power that technology is creating a new investment theme. Nuclear energy is no longer just part of the clean-energy transition—it is increasingly becoming a key pillar of the AI infrastructure buildout.
