At a time when the stock markets across the world are focusing on artificial intelligence, long-term players are also looking at sectors that will power the future of the AI space, most notably nuclear energy.
The year 2025 was massive for nuclear energy stocks, which saw exponential growth on the backs of AI boom and high-profile partnership.
Oklo stock (NYSE: OKLO) exploded nearly 379% in 2025 on soaring enthusiasm for small modular reactors, but is facing sharp headwinds next year in the form of regulatory approvals, dilution risks, and execution challenges.
As Oklo races against a July 2026 Department of Energy deadline and faces a fresh $1.5 billion share offering, 2026 will reveal whether the company’s promise is genuine or merely speculative froth.
Will Oklo stock clear the final hurdles?
Oklo’s entire business model hinges on clearing one of the nuclear industry’s most daunting challenges: winning approval from the Nuclear Regulatory Commission while delivering a first-of-a-kind reactor on time and on budget.
The company completed Phase 1 of the NRC’s pre-application readiness assessment in July and plans to submit its Combined Operating License Application by late 2025, but the real tests arrive in 2026.
The agency is expected to issue a draft evaluation of Oklo’s Principal Design Criteria in early 2026, a shortened timeline compared to traditional reviews, yet still unproven territory.
Any regulatory surprise or request for additional design modifications could cascade into months of delays, directly threatening the company’s stated goal of reaching commercial operation at Idaho National Laboratory by late 2027 or early 2028.
What amplifies the risk is that Oklo remains entirely pre-revenue and dependent on federal support.
Cash burn is accelerating, with operating losses widening from $17.8 million in Q2 2024 to $28 million in Q2 2025, even as the company boasts a $683 million cash buffer.
Sky-high valuation and the reversal risk
The market has priced in perfection. Oklo’s stock has swung wildly from a low of $17.42 to a peak of $193.84 in 2025.
Analyst price targets diverge sharply, ranging from $14 to $175, reflecting deep uncertainty about whether the company can justify a $16.3 billion market capitalization without any revenue streams visible before 2027 at the earliest.
In his latest article in The Motley Fool, analyst Adam Spatacco outlined that the nuclear energy sector has already priced in a lot of future optimism.
In 2026, I think investors will witness sharp corrections across a number of nuclear energy stocks, with Oklo being by far the most vulnerable in my opinion.
Oklo’s aggressive dilution, boosting share count by roughly 50% since 2024, creates a precarious scenario.
Even if the Aurora reactor succeeds, the accumulated shareholder dilution may offset long-term returns.
Investors should weigh Oklo’s long-term promise against the near-term gauntlet of approvals and capital raises.
