Oklo and NuScale Power Have Shed a Combined 85.3% This Year. Why Are Nuclear Stocks Falling?

Oklo (OKLO) and NuScale Power (SMR) have collapsed a combined 85.3% in 2026, unwinding last year's small modular reactor euphoria despite a $10 trillion nuclear energy opportunity tied to AI power demand.

The selloff stems from four concrete headwinds. First, investor risk appetite shifted away from speculative plays. Second, neither company expects meaningful cash flows until 2030–2040, leaving a decade-long commercialization gap. Third, ongoing shareholder dilution has eroded equity value. Fourth, both names entered the year overvalued after SMR hype peaked in late 2025.

The AI-driven nuclear thesis remains intact—data centers and AI workloads require reliable baseload power that modular reactors promise to deliver at scale. But the market is no longer willing to pay for a story two election cycles away. Investors who bought the narrative at the top are now facing the reality of negative free cash flow, equity raises, and regulatory timelines that stretch well into the next decade.

The Motley Fool notes the 2030–2040 commercialization window as the central problem: these are pre-revenue growth stories trading on hope, not fundamentals.
