Oklo posted its second-quarter 2026 financial results on August 7, and the company brought in $1.21 million in revenue during the quarter while recording a net loss of $48.5 million.
For context, Oklo reported zero revenue in Q2 2025. A million dollars is not exactly a windfall, but it is a line on the income statement that did not exist a year ago.
The financials, unpacked
The $48.5 million net loss is a meaningful step up from the $33.1 million loss Oklo posted in Q1 2026, suggesting the company is accelerating spending rather than pulling back.
AI meets nuclear: the Pluto reactor and Prometheus platform
Oklo is developing the Pluto reactor system, which is built around plutonium-bearing fuels, and it is applying an AI platform called Prometheus to that work.
Oklo’s partnership with Idaho National Laboratory, established in May 2026, is central to this effort. The collaboration gives Oklo access to institutional expertise as it refines the Pluto reactor’s fuel system design. The company has also worked with NVIDIA and Los Alamos National Laboratory on nuclear fuel validation.
Regulatory wins that actually matter
Oklo secured the first Department of Energy site use permit ever issued for a commercial advanced fission plant. Oklo also submitted the first custom combined license application to the Nuclear Regulatory Commission.
The bigger picture: nuclear’s moment
Electricity demand in the United States is rising, driven largely by data centers, AI computing infrastructure, and the broader electrification of industry. Advanced nuclear startups, Oklo included, have become the focus of serious policy attention and private capital as a result.
