Oklo and X-energy will join a $200 million, Trump administration–led program with Microsoft and Nvidia to accelerate the construction of new nuclear power plants for AI data centers, aiming to dramatically shorten design, licensing and build timelines while reducing the required workforce. The initiative, likely to be announced at a Department of Energy AI energy summit, is part of a broader federal push to expand nuclear capacity and address rising electricity costs from AI-driven data-center growth, with stock moves reflecting investor interest.
