Shares jumped +5% to $71.80 after the U.S. Nuclear Regulatory Commission approved the Principal Design Criteria for Oklo's small nuclear reactor in Idaho — a milestone that validates the company's core technology on a faster-than-normal government timeline and feeds directly into the AI-powered energy boom narrative.
The NRC Gave Its Blessing Faster Than Usual — And That Matters
The NRC approved the design criteria report for Oklo's reactor currently under construction in Idaho on an accelerated review schedule, reflecting the regulator's push to modernize licensing for advanced reactors.
Oklo's original submission was accepted in just 15 days, compared to a typical 30–60 day window.
The approval clears the path for the report to be referenced in future applications and reduces the need to re-review established material — meaning every subsequent reactor project could get licensed faster. For investors, velocity through the regulatory pipeline is the product right now.
A $12 Billion Valuation With Zero Revenue Is the Elephant in the Room
As of April 2026, Oklo has a market cap of $12.01 billion.
Oklo remains pre-revenue and faces multiyear regulatory and construction timelines, meaning execution risk is real and near-term cash flows are highly unlikely.
Commercial operations are targeted for late 2027 to early 2028. The stock is priced entirely on faith that AI data centers will need so much carbon-free electricity that a company burning cash today will mint profits tomorrow.
Big-Name Partners Are Lending Credibility — Not Cash
Oklo announced an agreement with NVIDIA and Los Alamos National Laboratory to advance nuclear infrastructure and AI-enabled research.
The agreement is centered on research rather than hardware purchase orders. Separately, Oklo signed a deal with Meta Platforms to develop a 1.2-gigawatt power-generation campus in Pike County, Ohio, to provide power to Meta's data centers. These partnerships boost the story but generate no revenue yet.
The Reactor Is Real, But So Is the Long Road Ahead
The Aurora is a 75-megawatt liquid metal–cooled fast reactor — small enough to sit near a data center. The NRC denied Oklo's first license application in 2022 due to lack of information , a stumble the company has since worked to overcome. Oklo has signed a DOE agreement to support the design, construction, and operation of its first reactor at Idaho National Laboratory under the government's Reactor Pilot Program. The question is whether execution matches the market's pricing: $12 billion for a company that has never sold a watt of electricity.
