Oklo Shares Rise 4% After Reactor Criticality

Oklo Reactor Achieves Criticality and Stock Gains

Oklo shares rose approximately 4% in pre‑market trading on Thursday after the United States announced that the company’s small modular nuclear reactor had reached criticality. Criticality denotes that the reactor has achieved a self‑sustaining nuclear chain reaction, marking a pivotal technical milestone for Oklo’s SMR technology.

The announcement underscores growing attention on the nuclear energy sector, particularly for clean baseload power solutions. Small modular reactors are promoted as more compact and potentially easier to deploy than conventional large‑scale nuclear plants, aligning with broader interest in clean energy deployment.

This market reaction reflects investor optimism regarding Oklo’s progress toward commercializing its SMR platform.
