Why is NuScale Power stock surging today?

NuScale Power stock surged roughly 11.0% in morning trading today, with shares reaching as high as $10.77, as a fresh wave of investor appetite for small modular reactor names swept through the nuclear energy sector despite a broadly negative tape for U.S. equities. No single company-specific press release or analyst action was identified as the trigger, pointing instead to a sector-wide momentum move that has repeatedly lifted SMR stocks throughout 2026 on the back of structural demand themes including AI data center power consumption and bipartisan political support for advanced nuclear deployment.

The move carries the hallmarks of catch-up buying. NuScale had touched a 52-week low of $7.21 in July 2026, leaving it significantly more discounted than peers such as Oklo and Nano Nuclear Energy heading into today’s session. The company’s fundamental underpinning remains intact: as of the end of the second quarter of 2026, NuScale reported approximately $1.89 billion in cash and investments and carried zero debt, providing a long runway to commercialization even as revenue remains minimal and losses continue.

The broader market offered no tailwind today, with the S&P 500 off 0.3%, the Nasdaq slipping 0.3%, and the Dow declining 0.9% — underscoring that the SMR sector is moving on its own momentum rather than macro support. Peer companies in the SMR space have seen repeated sector-wide rallies this year, driven by milestones such as Oklo’s Groves reactor achieving first criticality in August 2026 and a growing pipeline of technology-sector power purchase agreements, all of which have kept nuclear sentiment constructive.

Taken together, NuScale’s deeply discounted valuation relative to its SMR peers, its unmatched regulatory position as the first and only NRC-certified SMR developer, and the persistent sector enthusiasm around next-generation nuclear power combined today to produce an outsized move that stands in sharp contrast to the broader market’s cautious tone.
