Oklo shares rose about 4% and X-Energy gained roughly 3% on Wednesday after a report said the advanced nuclear developers are participating in a $200 million Trump administration-backed program designed to speed deployment of nuclear power for AI data centers. Oklo and X-Energy are expected to work alongside Microsoft and Nvidia under the initiative, which is intended to streamline the design, licensing and construction of advanced nuclear reactors while lowering development and operating costs. The program comes as electricity demand from artificial intelligence infrastructure continues to increase, driving interest in next-generation nuclear technologies capable of supplying reliable, carbon-free power to large-scale data centers.
