Helion Talks to Power OpenAI
Reports say Sam Altman’s fusion startup Helion is in early discussions to supply power to OpenAI, and that Altman stepped down as Helion’s board chair amid those talks. (xix.ai). The items are preliminary, but they highlight a growing strategic problem for large AI labs: ensuring dedicated, high‑quality electricity as compute needs scale. (xix.ai)
OpenAI is not just hunting for more computer chips. It is now reportedly trying to lock down electricity itself, with talks to buy power from Helion, the fusion company backed by Sam Altman. (techcrunch.com) Altman said on March 23 that he stepped down from Helion’s board as OpenAI and Helion began exploring work together “at significant scale,” while keeping his financial stake and recusing himself from negotiations. (money.usnews.com) The reported numbers are enormous. Axios, cited by TechCrunch and Reuters pickups, said OpenAI could seek 5 gigawatts by 2030 and 50 gigawatts by 2035, equal to 12.5% of Helion’s projected output. (techcrunch.com) A gigawatt is utility-scale power, not office-building power. OpenAI said in September 2025 that its Stargate buildout with Oracle and SoftBank had nearly 7 gigawatts of planned data center capacity and was targeting 10 gigawatts overall, so power procurement is becoming as central as server procurement. (openai.com) Helion is not a normal power supplier. It is a fusion startup in Everett, Washington, and fusion is the long-promised idea of making electricity by fusing light atoms together, the same basic process that powers the sun. (helionenergy.com) Helion already has one landmark customer on paper. In May 2023, it announced a deal to provide Microsoft electricity from its first fusion plant, with a target of at least 50 megawatts and an online date of 2028 after a one-year ramp. (helionenergy.com) In July 2025, Helion said it had secured land and started construction on that first commercial plant in Malaga, Washington. The company said the project would keep it on track to deliver fusion-generated electricity to Microsoft by 2028. (helionenergy.com) That is why the OpenAI talks stand out. Moving from one 50-megawatt first plant to a possible 5-gigawatt supply for OpenAI by 2030 would mean scaling from tens of megawatts to thousands, and the later 50-gigawatt figure would be larger still. (helionenergy.com, techcrunch.com) Altman’s link to both sides is also unusually direct. Helion said in 2021 that Altman’s involvement as investor and chairman dated back to 2015, which is why his board exit became necessary once OpenAI started looking at Helion as a supplier. (helionenergy.com) The thread running through all of this is that artificial intelligence companies are starting to behave like heavy industry. When a model company is planning data centers in the multi-gigawatt range, the bottleneck stops being only chips and starts being land, substations, transmission lines, and firm electricity contracts. (openai.com) The deal is still preliminary, and Helion has not yet delivered commercial fusion power to anyone. But even the conversation shows where the next race is moving: from who can train the biggest model to who can secure the cleanest and most reliable power at the largest scale.
