Rising AI adoption is driving massive energy demand from data centers, positioning nuclear energy—particularly small modular reactors (SMRs)—as an ideal solution. NuScale Power and Oklo are two early-stage SMR companies positioned to benefit from this trend, though both face regulatory hurdles and commercialization risks. Major investment banks including Goldman Sachs, Bank of America, and Morgan Stanley are bullish on nuclear's renaissance.

Oklo is developing advanced fast reactors designed to utilize the U.S.'s accumulated 100,000 metric tons of spent nuclear fuel, potentially reducing waste and expanding domestic fuel supplies. The company is investing $1.7 billion in a Tennessee fuel recycling facility and has major projects underway, including a 75-MWe reactor at Idaho National Laboratory and a 1.2-GW clean energy campus for Meta in Ohio. However, the company faces regulatory risks and significant capital expenditures before achieving commercial viability.

SpaceX plans to launch orbital data centers by 2027 to address AI's massive energy demands, but NuScale Power's small modular reactors (SMRs) may offer a more feasible and proven alternative. With data centers projected to consume 9% of U.S. electricity by 2030, NuScale's SMRs require less land, shorter construction times, and can be co-located directly with data centers, positioning it as a compelling investment opportunity in the growing AI energy sector.

Nuclear energy stocks experienced significant volatility in the first half of 2026 after surging in 2025. While Oklo and NuScale Power have declined sharply due to lengthy development timelines, Cameco stands out as a mature company positioned to benefit from growing uranium demand and its stake in Westinghouse. The article recommends Cameco as the best nuclear stock to buy on the dip, citing its established operations and near-term revenue potential compared to early-stage competitors.

NuScale Power, a small modular reactor (SMR) developer, has seen its valuation drop from $20 billion to below $4 billion following project delays. However, the article suggests significant upside potential if the company secures a power purchasing agreement by end of 2026 for its major 6-gigawatt SMR project. Growing AI data center demand and a projected $10 trillion global nuclear market could drive long-term growth, though execution risks remain.

Oklo stock fell 22% in June despite securing major wins including DOE safety approval, partnerships with Standard Nuclear and Centrus Energy for fuel supplies, and acquisitions of Creative Engineers and ARMEC. The decline was driven by a $1 billion equity offering causing dilution concerns, a $33 million Q1 net loss, and investor concerns triggered by the DOE's $17.5 billion loan program for large-scale reactors, which spooked SMR investors despite validating the broader nuclear energy sector.

Nano Nuclear Energy is a pre-commercial nuclear startup developing microreactors and aiming to build a vertically integrated nuclear supply chain. While the company could deliver impressive long-term returns if successful, it faces enormous risks including regulatory approval and the need for widespread microreactor adoption. The stock is characterized as a highly speculative play rather than a guaranteed millionaire-maker, with success dependent on commercialization, cost-competitiveness, and strong market demand.

Oklo Inc., a small modular reactor (SMR) developer, has partnered with the Battelle Energy Alliance to use AI for designing and building next-generation nuclear reactors. The company benefits from dual AI exposure: its customer pipeline consists of AI companies needing energy for data centers, and it now uses AI to accelerate its own product development. Despite shares being down 70% from their summer highs, tailwinds from AI data center energy demands and government support position SMRs as a potential growth opportunity.

SpaceX's IPO prospectus reveals that over 90% of its $28.5 trillion addressable market opportunity is AI-focused, but the company faces a critical energy constraint. AI data centers require massive amounts of reliable power, prompting tech giants like Alphabet to explore nuclear energy. Small modular reactors (SMRs) are positioned as a solution to traditional nuclear plants' long construction times. NuScale Power and Oklo are highlighted as pure-play SMR stocks, though both remain unproven commercially.

A conservative investor explains why they prefer Brookfield Renewable over pure-play nuclear stocks like Oklo and NuScale Power to gain exposure to AI-driven nuclear power demand. Brookfield Renewable offers a diversified portfolio of clean energy assets, 50% ownership of Westinghouse, an attractive 4%+ dividend yield, and power supply deals with major tech companies, making it a lower-risk alternative to untested SMR startups.

Nano Nuclear Energy (NNE) has surged 15% in the past month following a bullish $45 price target from Roth Capital. The company is developing microreactors with ambitions for vertical integration in the nuclear supply chain. While the AI data center power narrative is compelling, the company remains years away from deploying its first reactor, and success is far from guaranteed. Investors should recognize that risks of failure are currently as likely as success.

Centrus Energy Group's stock surged 12% after announcing a letter of intent with small modular reactor company Oklo to supply high-assay low-enriched uranium (HALEU) for up to five Aurora powerhouses in Ohio starting in 2029. The deal, which supports Meta Platforms' AI data centers, highlights growing demand for domestically sourced nuclear fuel as the U.S. nuclear power sector expands.
