Three Strategic Ways to Invest in Nuclear Energy in 2026

The global nuclear renaissance is accelerating. Driven by surging electricity demand from artificial intelligence infrastructure, corporate commitments to clean energy, and updated government policies prioritizing carbon-free power generation, nuclear energy is poised for significant expansion. Goldman Sachs projects that numerous countries will triple their nuclear capacity by 2050—a shift that creates distinct investment opportunities for those seeking exposure to this trend.

If you’re looking to build exposure to how to invest in nuclear energy, three companies offer compelling entry points, each with different risk-reward profiles. Let’s examine each investment path and what makes it unique for your portfolio.

The Innovation Play: Small Modular Reactor Technology

NuScale Power represents the cutting-edge technology bet in the nuclear space. The company is revolutionizing reactor design through small modular reactor (SMR) technology, which fundamentally changes how nuclear power plants are constructed and deployed.

Traditional nuclear plants are massive, site-specific, and require years of construction. NuScale’s approach flips this model: reactors are factory-built, modular, and can be transported to remote locations, industrial facilities, or positioned near population centers where power is needed most. This flexibility opens possibilities for data center operators, utilities in developing regions, and industries seeking reliable clean power without the mega-project overhead.

The regulatory path is advancing. NuScale holds U.S. Nuclear Regulatory Commission approvals for two SMR designs, positioning the company ahead of competitors. A Romanian utility, RoPower, is currently evaluating a six-reactor NuScale installation that would generate significant power through a chained configuration. A decision is anticipated within the coming year, and securing this first major customer would validate the technology and likely accelerate follow-on deals.

The trade-off: NuScale is still pre-revenue and cash-burn remains a concern. This is a growth-stage play best suited for investors with longer time horizons and higher risk tolerance. However, if SMRs capture even a fraction of the projected market, early believers could see substantial returns.

The Operator Play: Established Nuclear Leadership

Constellation Energy operates the nation’s largest fleet of nuclear power plants, positioning itself as the primary beneficiary of expanding nuclear demand from major technology companies. This is the “stable operator” entry point—less risky than pure-play technology bets.

Constellation’s strategy centers on leveraging its existing fleet to secure lucrative long-term power purchase agreements with tech giants. Microsoft committed to a 20-year contract for power from Three Mile Island Unit 1 when it restarts in 2028—835 megawatts flowing to Microsoft’s operations. Meta signed a similar 20-year agreement for 1.1 gigawatts from Constellation’s Clinton Clean Energy Center, beginning in June 2027. These aren’t speculative future contracts; they represent immediate, enforceable revenue streams.

The company projects adjusted operating earnings growth of over 13% annually through 2030—a robust rate for a utility. Management is also pursuing the $16.4 billion acquisition of Calpine, which would add natural gas and geothermal capacity to Constellation’s diversified fleet. This deal is projected to increase earnings per share by 20% next year alone, with an additional $2 per share contribution in subsequent years.

For investors seeking to invest in nuclear energy with less execution risk, Constellation offers established operations, contracted future revenues, and visible earnings growth. The company is almost certain to benefit from the nuclear resurgence.

The Resource Play: Uranium and Equipment Supply Chain

Cameco takes a different approach, profiting from nuclear expansion through two distinct pathways: uranium mining and nuclear equipment manufacturing.

First, Cameco is one of the world’s largest uranium miners. As nuclear reactor deployment accelerates globally—driven by data center operators, governments, and industrial users seeking carbon-free power—uranium demand will surge accordingly. Cameco has already secured commitments to deliver an average of 28 million pounds of uranium annually through 2029, locking in long-term revenue visibility. In its most recent quarter, the uranium division reported a 46% jump in pre-tax net income, reflecting both higher prices and increased sales volumes.

Second, Cameco holds a 49% stake in Westinghouse Electric, a major supplier of nuclear power plant equipment and fuel technologies. This division recently turned profitable, generating $126 million in pre-tax profits compared to a $47 million loss a year earlier. These earnings materialized from Westinghouse’s initial deliveries of fuel assemblies to nuclear plants in the Czech Republic. As reactor construction accelerates, Westinghouse’s equipment and services revenue will grow accordingly, flowing directly to Cameco’s bottom line.

Cameco’s stock reached nearly $83 per share in 2024, reflecting investor enthusiasm for nuclear resurgence. The company combines strong cash generation with a robust balance sheet that cushions it from uranium price volatility. For investors seeking nuclear energy exposure through commodity and supply-chain leverage rather than utility operations or emerging technology, Cameco offers one of the simplest paths forward.

Making Your Investment Decision

Each path reflects a different investment philosophy. NuScale suits investors betting on technological disruption and willing to accept higher volatility. Constellation appeals to those seeking lower-risk, contracted growth from established operations. Cameco attracts those wanting to play the resource and manufacturing boom underlying nuclear expansion.

The broader tailwind is certain: the convergence of AI electricity demand, climate commitments, and nuclear normalization creates a decade-long growth opportunity. Whether you invest in nuclear energy through technology innovation, operational leadership, or resource supply is ultimately a function of your risk tolerance and investment horizon. All three pathways offer genuine exposure to a sector positioned for sustained expansion through 2030 and beyond.
