Helion has reached a $15.5B valuation with $465M in new capital as it aims to sell off the merger this decade.
Helion Energy, the first race to sell fusion power, announced $465 million in new funding on Thursday, bringing its total funding to more than $1.5 billion. The Everett, Wash.-based company said it is now valued at $15.5 billion.
The company aims to be the first in the world to do fusion, replicating the reactions that power the sun and stars to produce nearly unlimited clean energy. In a statement, Helion founder and CEO David Kirtley said his company is in the best position to produce hybrid electricity this decade.
Helion is working under the industry’s most important timeline, signing an agreement with Microsoft to provide power to the Central Washington data center by 2028. The company broke ground on a 50-megawatt plant, called Orion, last July in Malaga, Wash.
Many experts say significant hurdles remain before any company can achieve commercial consolidation. Helion’s critics also raise concerns about the startup’s secrecy and limited scientific publications, making it difficult for independent researchers to test its methodology.
Helion leaders acknowledge that significant technical issues still need to be resolved in the final designs of its assembly plant. The company is conducting tests in Everett on the Polaris, its seventh-generation 60-foot-tall merging device, and recently revealed it is building another device called the Tiny Merge, which is about one-eighth the size of the Polaris.
“With this aging testbed, we’ll be able to test new ideas with much less energy and fewer resource requirements, meaning we can iterate faster than we can on full-scale missions like Polaris,” Michael Hua, Helion’s senior director of radiation safety and nuclear science, recently told GeekWire.
Commonwealth Fusion Systems is also striving to be the first to use fusion, targeting the early 2030s. The Massachusetts-based company has raised about $3 billion. On Wednesday, the company announced that five peer-reviewed scientific papers have confirmed the physics behind its energy synthesis method.
The Helion Series G round was led by Thrive Capital, with participation from additional new investors including Alta Park Capital, Anti Fund, BoxGroup, Lux Capital, Peak XV Partners and Ford Motor Company Chairman Bill Ford.

Existing backers also participated, including Capricorn Technology Impact Funds, Lightspeed Venture Partners, Mithril Capital, Dustin Moskovitz through Good Ventures Foundation, SoftBank Vision Fund 2 and the university’s endowment fund.
It marks the largest fundraising in the Pacific Northwest so far this year, according to GeekWire’s funding list. (Sedron Technologies, a wastewater treatment startup, raised $500 million in a private equity buyout in April).
Helion sits at No. 1 on the GeekWire 200, a Pacific Northwest startup ranking.
OpenAI CEO Sam Altman is a major investor in Helion and revealed during the recent Musk v. Altman that owns about one third of the company. OpenAI has reportedly explored a power purchase agreement with Helion, although Altman says he was not part of those discussions. He resigned from Helion’s board in March.
