Oklo Plans Aurora Microreactor Criticality Test by July 4, 2026 Under DOE Program
Oklo is building its first Aurora microreactor at Idaho National Laboratory, expected to achieve criticality by July 4, 2026, under a DOE oversight program. The pre-revenue company carries an approximately $12 billion market cap and must secure NRC approval for commercial reactor operations before generating any revenue.
1. Company Overview and Market Performance
Oklo is a pioneer in the design of advanced small modular reactors intended to serve the growing energy demands of AI data centers. Backed by Sam Altman as a significant investor and former board chairman, the company’s valuation has swelled to approximately $11 billion despite having no commercial revenue to date. Shares more than tripled over the past year, reflecting strong investor enthusiasm for next-generation nuclear technology even as Oklo remains in the pre-revenue stage.
2. Technology Milestones and DOE Partnership
The firm is currently constructing its first demonstration unit, the Aurora powerhouse, at the Idaho National Laboratory under a Department of Energy oversight agreement. This facility is slated to achieve criticality by July 4, 2026, a key technical milestone that would validate the microreactor’s operational design. Successful demonstration would position Oklo to scale its technology for continuous power delivery to industrial and data-center environments requiring stable, high-density energy sources.
3. Regulatory Path and Future Outlook
A critical next step for Oklo is obtaining a commercial operating license from the U.S. Nuclear Regulatory Commission. Without this approval, the company cannot commence revenue generation, and cash expenditures on development and testing will continue. Management projects that, upon licensing, commercial deployments could begin within two to three years, creating a pathway to revenue and potential profitability. Investors should weigh the speculative nature of pre-approval operations against the long-term upside of securing a position in the evolving nuclear energy landscape.
