Uncommon card · No. 137443

Oklo Inc. is a publicly traded American nuclear power company based in Santa Clara, California. The company develops a small modular nuclear reactor, the Aurora Powerhouse, and intends to sell both electricity and radioisotopes produced by their Aurora reactors. The company's name is derived from Oklo, a region in the country of Gabon, Africa, where self-sustaining nuclear fission reactions occurred approximately 1.7 billion years ago. Founded in 2013 by Jacob and Caroline DeWitte, Oklo Inc. focuses on fast-fission power plants. OpenAI co-founder Sam Altman served as Chairman of the Board of Directors, but stepped down in April 2025 to "avoid a conflict of interest ahead of talks between his company and the nuclear start-up on an energy supply agreement."
