Key Takeaways:
Nuclear power has shifted from a contested energy source to a strategic imperative as surging electricity demand from artificial intelligence data centers and electrification drives a global reassessment of baseload generation capacity.
The global energy landscape is leaning toward an emphasis on security and sustainability, and nuclear power's role has evolved from a debated alternative to a strategic necessity. Bank of America analysts, in a new report on the sector, called nuclear energy a $10 trillion opportunity that could hold "the answer to the world's power shortages."
"Nuclear energy has, in many ways, been recently 'rediscovered' amid surging electricity demand," the bank's analysts wrote. "Compared with other energy sources, it offers reliable baseload power, a smaller carbon footprint, and a higher energy return on investment."
Morgan Stanley analysts broadly agree, though with slightly differing forecasts. Global nuclear capacity could more than double to 860 gigawatts by 2050, a recent Morgan Stanley report predicted, with investments in the nuclear value chain reaching $2.2 trillion over the next 25 years.
The catalyst behind the shift is unmistakable: U.S. electricity use hit new highs last year, with 2026 and 2027 also expected to reach record levels, driven largely by data centers dedicated to artificial intelligence, according to Reuters. Without nuclear, the AI and data center industries may struggle to source new power generation, limiting overall growth potential.
Oklo and the SMR Pipeline
Oklo (NYSE: OKLO), backed by OpenAI founder Sam Altman, is among the most direct nuclear plays for AI investors. The company specializes in small modular reactors, or SMRs — factory-built units typically under 300 megawatts electric that can be co-located with data center infrastructure. Oklo calls them "microreactors," and the company already has an agreement with Meta Platforms in its customer pipeline.
SMRs address a key constraint for data center operators: the multi-year construction timelines and massive land requirements of conventional nuclear plants. Oklo's design can operate for decades without refueling, eliminating the need for grid interconnection in remote locations. The company has not yet received NRC license approval for commercial operation, and no timeline for first power has been confirmed.
Grid-Scale Storage Meets AI Demand
Fluence Energy (NASDAQ: FLNC) is pursuing a different path to the same end market. Siemens and Nvidia recently announced a three-way collaboration with Fluence to create an AI data center reference architecture integrating Fluence's Smartstack battery platform to support power-intensive Nvidia DSX Vera Rubin "AI factory" designs.
While the blueprint does not represent firm orders, it positions Fluence's grid-scale storage at the center of how future AI data centers could manage grid constraints and reliability challenges. Fluence completed a $420 million follow-on equity raise in May 2026 to support liquidity and project execution, while reaffirming 2026 revenue guidance of $3.2 billion to $3.6 billion.
Investment Implications
For investors, the nuclear renaissance presents a multi-trillion-dollar opportunity spanning reactor developers, uranium miners, and grid infrastructure providers. Oklo trades on the promise of SMR deployment but carries execution risk tied to regulatory approval and construction timelines. Fluence offers a more immediate path to monetizing AI-driven power demand through battery storage, though the company remains unprofitable and recent equity raises have diluted existing shareholders.
Bank of America's $10 trillion estimate, if realized, would represent one of the largest capital deployment cycles in energy history. The key variable is timing: Morgan Stanley's 2050 horizon means the payoff for early investors could take decades, while near-term beneficiaries include uranium producers and companies with existing nuclear assets in regulated markets.
