Oklo Inc., backed by Sam Altman, sparked a rally after revealing talks to join a US Department of Energy program that supplies nuclear fuel.

The company said it seeks participation in an initiative designed to ease bottlenecks that could slow fission power deployment. By aligning with the federal effort, Oklo positions itself to secure a steady supply chain for its reactor technology.

Market watchers note that the move could elevate Oklo’s valuation, as investors prize early access to government contracts in a sector facing supply constraints. A partnership with the DOE would also signal confidence in the company’s design, potentially attracting further capital.

The announcement lifted Oklo’s stock sharply, reflecting investors’ belief that the deal could unlock new revenue streams and reinforce the company’s standing in the competitive nuclear landscape.
