Oklo stock jumped more than 13% in mid-day trading on Tuesday after the U.S. Nuclear Regulatory Commission (NRC) approved a key design document for the company’s Aurora powerhouse reactor currently under construction in Idaho.

The stock hit an intraday high of $79.03 before pulling back slightly, trading around $78.45.

The NRC approved Oklo’s Principal Design Criteria (PDC) topical report on an accelerated review schedule. That schedule reflects the regulator’s push to modernize licensing pathways for advanced reactors.

The PDC approval sets out the fundamental safety, reliability, and performance requirements that will guide future reactor licensing and design work. It also means the report can be referenced in future applications, cutting down the need to re-review the same material.

Texas Capital Reiterates Buy

Texas Capital Securities analyst Nate Pendleton reiterated a Buy rating and $120 price target on Oklo after the news. Pendleton described the PDC approval as “another incremental step forward” while pointing to the “increasingly efficient regulatory path for advanced reactor solutions.”

Oklo currently holds a “Moderate Buy” consensus, supported by fresh coverage from both Tigress Financial and HSBC.

The accelerated NRC review ties directly to executive orders issued by President Trump in May 2025, aimed at clearing a faster route for advanced nuclear energy projects. It also aligns with the ADVANCE Act, which pushes for a more efficient deployment path for advanced nuclear technology.

The bear case for Oklo has long centered on the company failing to secure the necessary regulatory approvals. Tuesday’s NRC decision chips away at that thesis, though the company still needs further approvals before it can begin commercial operations.

Oklo is a pre-revenue company, so regulatory progress is closely watched by investors as a proxy for execution.

Nuclear Sector Rallies

The move wasn’t limited to Oklo. NuScale Power and Nano Nuclear also traded higher as the nuclear sector posted back-to-back rally sessions. The broader market was also supportive, with the S&P 500 up 1.08%, the Dow up 1.07%, and the Nasdaq up 1.46%.

Beyond the Idaho project, Oklo is working with Meta Platforms on a 1.2 gigawatt nuclear power project in Ohio to support Meta’s regional data centers.

Oklo’s Q1 2026 earnings call is scheduled for May 12.
