Altman's Helion Bet Draws Scrutiny as OpenAI Trial Unveils Wealth

In testimony for OpenAI’s for-profit trial, Sam Altman disclosed his stake in Helion Energy is worth over $1.6 billion as of late 2025 (about one-third of the company), after investing since 2015; the court exhibit also shows sizable holdings in Stripe ($632 million) and Retro Biosciences ($258 million), plus smaller stakes in Trialspark and Cerebras. Altman said he recused himself from a planned Helion–OpenAI power deal and stepped down as Helion chair in March 2026 amid questions from Elon Musk’s side about conflicts of interest and Altman’s broader investments, including Reddit shares.

Microsoft invests in nuclear fusion with Helion power purchase deal.

Microsoft has signed a power purchase agreement with Helion Energy, a private US nuclear fusion company, to provide electricity in about five years. Helion's plant is expected to be online by 2028 and will target power generation of 50 megawatts or greater after a one-year ramp-up period. Fusion could one day help the world slash emissions linked to climate change. Unlike today's fission reactors, it could generate power without producing long-lasting radioactive waste.

Microsoft partners with Helion Energy for fusion power in 2028.

Helion Energy has announced an agreement to provide Microsoft with electricity from its first fusion power plant, with Constellation serving as the power marketer and managing the transmission for the project. Helion's plant is expected to be online by 2028 and has a power generation target of 50MW, or greater, with a one-year ramp-up period. Fusion produces next to no waste or radioactivity while processing and is far less risky than fission.

Microsoft's Big Bet on Fusion Power from Helion by 2028.

Microsoft has signed a power purchase agreement with nuclear fusion startup Helion Energy to buy electricity from it in 2028. The deal is a notable vote of confidence for fusion, which holds promise of being able to generate nearly unlimited clean power, if it can be harnessed and commercialized on earth. Helion's deal with Microsoft is the first time a fusion company has inked a deal to sell electricity. Helion was founded in 2013 and currently has about 150 employees, with headquarters in Everett, Wash.

Microsoft's Big Bet on Nuclear Fusion Power with Helion's Electricity Purchase Deal.

Microsoft has signed a power purchase agreement with Helion Energy to purchase electricity from a nuclear fusion generator, which could potentially provide a limitless source of clean energy. Helion Energy aims to plug in the world's first commercial fusion generator to a power grid in Washington by 2028, generating at least 50 megawatts of power. The company uses a plasma accelerator to heat deuterium and helium-3 into a plasma and then uses pulsed magnetic fields to compress the plasma until fusion happens. However, experts remain skeptical about the feasibility of achieving this breakthrough in such a short span of time and making it cost-competitive with other energy sources.
