Oklo, X-Energy Tapped for $200M US Nuclear-AI Program

Advanced-reactor developers Oklo and X-Energy are being pulled into a $200 million federal push to speed nuclear power for AI data centers, Bloomberg reported on July 21. Microsoft and Nvidia are named alongside them as partners, with details expected to be unveiled at a Department of Energy AI energy summit as soon as Wednesday.

The structure, as reported, has $60 million over three years flowing to several DOE national laboratories and academic institutions including the University of Texas at Austin. The stated goals are practical rather than exotic: shorten how long it takes to design, license and build a new plant, and reduce the number of staff needed to run one. That framing reads as an admission that the current cost and timeline of American nuclear is not compatible with the pace at which hyperscalers want new gigawatts.

Markets took the report at face value. Oklo climbed as much as 9.9% in extended trading and X-Energy rose as much as 12%, according to the same reporting, per a Seeking Alpha writeup of the Bloomberg story. That is a large move for a program whose formal terms had not yet been announced, which is a fair signal of how starved investors are for a credible policy path from AI power demand to actual electrons on the grid.

The honest caveat is that this is a scoop about a program that had not been formally unveiled at the time of publication, so the split of the $200 million across the four named participants, the specific regulatory relief on offer, and which AI facility gets powered first are all things the reporting does not answer. Energy Secretary Chris Wright has been publicly framing nuclear as the natural companion to AI's power appetite, so the direction of travel is clear even if the plumbing is not.

The forward-looking part is who benefits if this holds together: two named reactor vendors get federal cover and validation, hyperscalers get a subsidized path to firm compute power, and the SMR competitors not on the list will have to explain to their boards why they were not chosen.
