(Bloomberg) — Oklo Inc. and Vistra Corp. shares rallied, leading peers higher, after Meta Platforms Inc. agreed to a purchase nuclear power from the companies to run artificial-intelligence data centers.

Oklo shares gained as much as 19%, while Vistra shares rose as much as 16%. Peers NuScale Power Corp. also rose on the news as did uranium producers like Centrus Energy Corp. and Cameco Corp.

“This news is incrementally positive for the entire nuclear energy industry, including Oklo, as it reaffirms the commitment from hyperscalers to start leveraging new energy sources to fuel the AI Revolution with power being the biggest headwind to the industry,” Wedbush Securities analyst Dan Ives wrote in a note to clients.

Meta signed a 20-year power purchase agreement with Vistra at its two existing power plants and struck another deal with Sam Altman-backed Oklo that will advance its small modular reactor development. Small modular reactors have not yet been commercialized.

Tech giants and other data center developers are requiring large supplies of power to feed their increasingly bigger data centers. That has fueled a backlash against the tech companies as households and other businesses contend with rising energy bills.

The nuclear power industry, whose revival would allow the tech companies to tap into new supplies, had been experiencing declines, with soaring costs and reactors shutting down before AI revived the industry and sent stocks soaring. Oklo shares gained over 200% in 2025, while Vistra shares gained 17% in 2025 after rising over 200% in 2024.
