Oklo Inc. (NYSE:OKLO) saw its stock rise 6.1% in premarket trading Monday after announcing a strategic partnership with Swedish nuclear company Blykalla AB, including a $5 million investment commitment.
Through this agreement, the U.S.-based Oklo will co-lead Blykalla’s upcoming funding round with the $5 million commitment, reinforcing transatlantic cooperation aimed at accelerating the commercialization of advanced nuclear technology. The partnership emphasizes technology collaboration, supply-chain alignment, and the exchange of regulatory expertise between the two firms.
A Joint Technology Development Agreement will see the companies sharing knowledge on materials, components, non-nuclear supply chain sourcing, fuel fabrication, and licensing best practices across the U.S. and Sweden. The collaboration seeks to reduce costs and mitigate schedule risks for both parties.
This initiative marks one of the first transatlantic partnerships in the advanced nuclear reactor sector. The firms will explore shared suppliers for reactor-agnostic equipment to enhance availability, timelines, and cost efficiency. Oklo may also provide select components for Blykalla’s operations and offer fuel fabrication services.
Oklo co-founder and CEO Jacob DeWitte said, “This partnership strengthens the growing advanced reactor ecosystem in the face of unprecedented global demand for power. By teaming up on suppliers, materials data, and licensing insights, we can shorten critical paths to deployment and stay focused on delivering reliable, clean power to customers, while recognizing that we have more to gain from cooperating than from competing.”
Oklo is developing sodium-cooled fast reactors with capacities of up to 75 MWe, targeting deployment at U.S. sites to serve industrial, defense, and data-center clients. Blykalla is working on a 55 MWe lead-cooled fast reactor, building on more than 25 years of research.
