Meta announced deals with three nuclear power providers on Friday, including one backed by OpenAI CEO Sam Altman, as part of its efforts to secure the resources needed for its AI ambitions.
Arrangements with VistraTerraPower and Okloall of which work on nuclear power technologies, are for Meta’s Prometheus supercluster computing system, being built at a data center in New Albany, Ohio. No financial terms were disclosed.
Shares of Vistra and Oklo soared following the news, rising 10% and 8%, respectively. Meta shares closed up 1%.
Meta CEO Mark Zuckerberg announced Prometheus in July, describing the system as one of the keys to expanding the company’s advanced artificial intelligence efforts. Meta said it expects Prometheus to go live sometime in 2026.
Working with the three companies on energy production, Meta said the projects are expected to add 6.6 gigawatts of electricity by 2035, surpassing New Hampshire’s total demand.

“State-of-the-art data centers and AI infrastructure are critical to securing America’s position as a global leader in AI,” Joel Kaplan, Meta’s chief policy officer, said in a statement.
The company said it would help finance Vistra’s nuclear power plants in Ohio and Pennsylvania, extending the life of those facilities and increasing their energy output. The nuclear projects of the other two companies are still in development.
Meta expects the deals to create “thousands of construction jobs and hundreds of long-term operational jobs.”
The deals mark Meta’s latest efforts to secure the energy needed to power its AI infrastructure, as the company moves toward Zuckerberg’s goal of developing superintelligence, a term used to describe AI that can far exceed the capabilities of humans on many tasks.
Meta’s large-cap rivals are also turning to nuclear power to power their AI work. Meta, Amazon And Google signed a commitment in March to triple global nuclear power production by 2050.
In June, Meta announced a 20-year agreement with Constellation Energy to purchase nuclear power from the company’s Clinton Clean Energy Center in Illinois starting in 2027.
Meta’s deal with TerraPower will finance two of the energy company’s nuclear projects under development that could begin producing electricity by 2032, according to Friday’s announcement. Meta said it could obtain rights to more energy from up to six other TerraPower nuclear power projects scheduled for delivery by 2035.
Meanwhile, the Oklo Advanced Nuclear Technology Campus is expected to come online as early as 2030 in Pike County, Ohio, Meta said.
OpenAI’s Altman is one of Oklo’s largest investors, owning a 4.3% stake worth about $650 million as of Thursday’s close, according to FactSet. Oklo went public in 2024 through a special purpose acquisition company co-founded by Altman.
Altman resigned as chairman of Oklo’s board in April to help the company secure more customers from companies competing with OpenAI.
