Helion adds $50M private investment alongside $175M federal chip award
What's the deal? Fusion startup Helion Energy has raised $50 million in a late-stage private round, announced October 22, alongside a $175 million federal award from the US Department of CommerceDealroom has a profile for this one. Try Dealroom → to develop advanced semiconductors for its fusion power plants. The company did not disclose the investor behind the private round.
Why now? Helion is racing to meet a 2028 deadline to supply Microsoft with electricity from Orion, its first power plant, under a 2023 agreement — the first power purchase deal for fusion energy. The federal money, awarded over three years under the CHIPS Act, will fund automated semiconductor production in Washington State, the first US line to make this class of chip.
What's the endgame? Helion harvests electricity directly from fusion reactions rather than heating steam to spin a turbine, making power electronics central to its design. Current devices lose 5% to 10% of the electricity passing through them. "If we can cut that loss in half, that's actually twice the power output of the fusion system," co-founder and chief executive officer David Kirtley told TechCrunch.
More than $100 million of the federal award goes to semiconductor and packaging research in Washington State, with roughly $80 million for work in Vermont with GlobalFoundries. Helion has now raised more than $3.2 billion, making it the second-best-funded fusion startup.
What could go wrong? Kirtley acknowledged the research won't reach Orion before launch, as federal contracts take months to negotiate; the gains are meant for later plants. The 2028 target remains a substantial execution challenge, and the chip work's value depends on proving the efficiency gain in an operating system.
The signal: The round adds to a fusion financing wave — Helion raised $465 million in June, Commonwealth Fusion Systems $1 billion in July, and Type One Energy $200 million in October. The money reflects rising investor appetite, but also the enormous capital needed to move from experimental machines to commercial power plants.
