Helion, founded in 2013 and based in Everett, Washington, develops fusion generators and says it is "Building the world's first fusion power plant." Its FAQ says its Polaris machine has begun operating, and its first commercial plant, Orion, is under construction in Malaga, Washington, to supply electricity to Microsoft.

The Washington Department of Health. It issued Orion's Radioactive Materials License and Radioactive Air Emissions License in June 2026. At the federal level, the Nuclear Regulatory Commission decided in 2023 to regulate fusion under its byproduct material program, Congress codified that approach in the ADVANCE Act of 2024, and the NRC published a proposed rule to implement it in February 2026. Washington, as an Agreement State, does the licensing. Land use at the site is governed by Chelan County's Conditional Use Permit.

Helion's October 15, 2025 release says Chelan County granted a Conditional Use Permit for a High Impact Utility Facility, decided by the county hearing examiner after a public notice and comment period. The permit, county file CUP 25-201, covers fusion-based power generation at the Orion site in Malaga. The hearing examiner heard the application on October 1, 2025, and the Everett Herald reported approval on October 14, 2025.

Helion's FAQ says the company has a power purchase agreement with Microsoft for its first commercial plant, and links Axios coverage describing it as at least 50 megawatts beginning in 2028. Helion's October 15, 2025 release says the 2023 agreement calls for delivery by the end of 2028, that Constellation Energy is the power marketer, and that Helion remained on track. CEO David Kirtley told CNBC in 2023 that Helion faces financial penalties if it cannot deliver. The power is to come from Orion, which is still under construction.

On October 22, 2026 Helion announced a letter of intent with the U.S. Department of Commerce's CHIPS Research and Development Office for up to $175 million in federal funds, plus $50 million in private investment, to develop high-voltage semiconductors for its fusion systems. Helion says Commerce would receive a $175 million non-voting interest in the company once a definitive award agreement is signed; until then the award is not final.

One federal case names Helion Energy, Inc.: Andrews Cooper Technology v. Helion Energy, No. 2:25-cv-00323 (W.D. Wash.), a breach of contract suit filed in February 2025 that ended by stipulation and order on November 13, 2025. CourtListener lists no case naming Helion One. To look up a case, search the party name Helion Energy, Inc., and project companies such as Helion One, LLC, which may be named separately, in federal court records on PACER or CourtListener, and in Washington state court records through the Washington Courts case search. Helion came up during the 2026 Musk v. Altman trial because of Sam Altman's stake in the company. Helion's website Terms of Use say claims concerning the website or those terms proceed "solely on an individual, not class action or representative basis, in binding arbitration" under American Arbitration Association rules; that clause is limited to the website and its terms.

Trustpilot has an unclaimed page for helionenergy.com, but its three reviews name Hellio, a French energy-savings company, and concern heat pumps, solar and energy-savings premiums, none of which Helion offers.

Helion's website lists no phone number, and numbers shown for it on directory sites do not come from that website. The email address in its Privacy Policy and Terms of Use is [email protected], and its Contact page has a web form with a General topic.

Helion Energy, Inc. is a private fusion company in Everett, Washington. The Washington Department of Health issued radioactive materials and air emissions licenses for its Orion plant in June 2026, and its $500 million Series G round, closed in September 2026, was led by Thrive Capital. Its fusion results, including the Polaris temperature figure, are the company's own announcements, and they do not report electricity from fusion, which its FAQ gives as the goal for Polaris. Orion is still under construction, so its electricity for Microsoft, targeted for 2028, has not been delivered.

David Kirtley, a co-founder, is the CEO. Helion is privately held and its site names no single owner. Sam Altman, who first invested in 2015 and left the board on March 23, 2026, testified in the Musk v. Altman trial in May 2026 that he owns roughly one-third of the company; financial disclosures in the case valued the stake at about $1.65 billion as of late 2025. Other investors the company has named include Dustin Moskovitz, Reid Hoffman, SoftBank Vision Fund 2, Lightspeed Venture Partners, Thrive Capital and Nucor.
