On June 18, Oklo Inc. rose 5.34% in regular trading, trading at $61.97/share, with turnover of $236 million. The rally was driven by the announcement that Oklo and Centrus Energy have signed a letter of intent covering the supply of high-assay low-enriched uranium (HALEU) to support Oklo's planned 1.2-gigawatt campus in southern Ohio.

Under the agreement, Centrus will supply domestic HALEU from its American Centrifuge plant in Pike County, Ohio, with deliveries slated to begin in 2029. The supply volume is sufficient to power up to five Aurora powerhouses for several years, and the LOI may include prepayments from Oklo to Centrus to support fuel supply for the campus buildout.

This development adds to a series of recent catalysts: the U.S. Department of Energy's Idaho Operations Office formally approved the preliminary documented safety analysis for Oklo's Aurora powerhouse on June 11, covering hazard analysis, accident analysis, safety controls, and design commitments. Additionally, Oklo signed a memorandum of understanding with Standard Nuclear to explore nuclear fuel recycling and advanced fuel manufacturing. The convergence of fuel supply security, regulatory milestones, and strategic partnerships continues to reinforce market confidence in Oklo's commercialization trajectory.
