On July 27, Oklo Inc. rose 5.61% in regular trading, trading at $42.36/share, with turnover of $57.63 million. The stock rebounded after a 5.7% decline on July 24, when profit-taking followed the formal announcement of DOE startup authorization for its Groves Isotope Test Reactor.

On the news front, Oklo announced on July 24 that its Groves Isotope Test Reactor (GITR) received startup authorization from the U.S. Department of Energy, clearing the path for fuel loading, startup testing, and full operation. The company emphasized the project was entirely privately funded and built on private land, demonstrating a scalable commercial model for advanced nuclear reactor development. CEO Jacob DeWitte stated the achievement proves advanced nuclear energy can advance far faster than market expectations.

The broader Electric Utilities sector showed slight weakness, with NextEra down 0.04%, Southern down 0.09%, Constellation Energy down 1.2%, Duke down 0.55%, and Exelon down 0.33%, making Oklo a clear outperformer. The rebound follows a period in which the stock gained over 13% from July 21-22 on nuclear sector catalysts including participation in a Trump administration-led next-generation nuclear power plan targeting AI data center energy demand.
