Helion and CFS give U.S. government equity stakes for $260M in CHIPS Act funding

What the funding includes

The U.S. Department of Commerce has awarded a total of $260 million to two fusion energy startups, Helion and Commonwealth Fusion Systems (CFS), under the CHIPS and Science Act. Helion received $175 million, while CFS secured $85 million. In exchange for the awards, both companies have agreed to grant the government non-voting equity stakes.

Equity stakes and valuations

Helion’s equity stake for the government is approximately 1%, based on the company’s Series G valuation of $15.5 billion. The stake is non-voting, meaning it does not confer control or decision-making authority to the government. CFS’s valuation for its government stake has not been disclosed, but it follows the same non-voting structure.

This approach aligns the financial interests of the government and the startups, as noted by Helion CEO David Kirtley: the government’s stake allows U.S. taxpayers to benefit from the company’s commercial success in exchange for funding research and development.

A shift in government funding models

Government funding for fusion energy has historically been non-dilutive, meaning startups did not have to surrender equity. This latest round of awards marks a departure from that model, introducing equity stakes as a condition for public funding. The Fusion Industry Association had previously called for a $10 billion federal infusion into the sector, with $5.4 billion earmarked for startups, but the equity-based approach was not part of that proposal.

The U.S. is not alone in exploring equity-based public funding. In Germany, Proxima Fusion has accepted investments from government-backed funds like SPRIND and Deutsche Climate Tech Fonds (DCTF), placing both the German government and the European Union on its cap table. Similarly, U.S. companies like MP Materials and USA Rare Earth have granted equity stakes to the government in exchange for funding awards.

Broader context: Why fusion energy?

This funding shift comes as governments race to secure leadership in fusion energy, a sector with the potential to reshape global energy markets. The U.S. and China are competing aggressively to commercialize fusion technology, and the CHIPS and Science Act reflects a broader U.S. strategy to counter China’s advances in critical industries. Earlier reporting on Intel’s resumption of stalled U.S. chip plant expansions highlights a similar focus on reviving domestic manufacturing in strategic sectors.

The U.S. and Germany are also collaborating on deeptech and AI infrastructure, as seen in recent initiatives to create industrial tech corridors. Proxima Fusion’s inclusion of German and EU investors underscores Europe’s parallel efforts to build a competitive fusion energy ecosystem.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

This funding shift reflects a broader trend of public-private partnerships where governments take a direct—albeit non-voting—stake in high-risk, high-reward industries. For founders, it signals two things: first, that fusion energy remains a strategic priority for U.S. policymakers, and second, that accessing public funds may now require conceding equity, even if it doesn’t dilute control. The model isn’t entirely new—companies like MP Materials and USA Rare Earth have done the same—but its application to fusion startups could set a precedent for other deeptech sectors. Operators should weigh the long-term implications of sharing equity with taxpayers, particularly if future funding rounds or exits become more complex.

Key takeaways

• Founders in capital-intensive industries like fusion energy may face increasing pressure to offer equity stakes to secure government funding.
• The U.S. government’s equity-based approach could influence other countries to adopt similar models, particularly in sectors where China is seen as a competitor.
• Non-voting equity reduces immediate control risks but may complicate future fundraising or strategic decisions.
• This funding structure aligns government and private interests, potentially accelerating commercialization but also tying startups more closely to policy shifts.
