Helion and CFS Trade Equity for $260 Million in Federal Awards

Helion and Commonwealth Fusion Systems accepted $260 million in federal awards last week — and paid for them with equity. The Department of Commerce, acting under the CHIPS and Science Act of 2022, awarded Helion $175 million and Commonwealth Fusion Systems $85 million to develop advanced semiconductors that power and control their reactors. Both companies agreed to hand the government non-voting shares in return.

The dollar amounts are small change for these two. CFS has raised roughly $4 billion; Helion sits close behind with $3.2 billion in committed capital. The real story is the structure. Washington is no longer just writing checks to boost American innovation — it wants a piece of the upside when it picks a winner.

How big are the government's stakes?

Helion said the government will receive $175 million in non-voting equity pegged to its Series G round, which valued the company at $15.5 billion. That works out to roughly 1% of the company. CFS's stake will also be non-voting and based on its most recent valuation — a number CFS has never disclosed publicly. So nobody outside the company knows how large the government's slice actually is.

"This type of structure has become more common in large U.S. government investments in recent years," David Kirtley, co-founder and CEO of Helion, told TechCrunch in a statement. "This approach aligns the interests of Helion and the U.S. taxpayer around our commercial success."

CFS echoed the framing. "This U.S. equity stake will enable the U.S. taxpayer to participate in the upside of our commercial success in exchange for investing in important research and development that supports the growth of an American commercial fusion industry," a company spokesperson said.

What does this change for startups and their investors?

For decades, a government award meant non-dilutive capital — free money that padded a startup's war chest without shrinking existing investors' ownership. VCs loved those deals: more cash, no dilution. The Trump administration has been pushing to change that calculus, and the fusion sector just became the latest to feel it.

The precedent is already crowded. Last year, critical minerals supplier MP Materials gave the government a 15% stake in exchange for a $400 million investment, a $150 million loan, offtake agreements and profit sharing. USA Rare Earth gave up 10% for a $277 million award and a $1.3 billion loan. Intel's case may be the most awkward: the Biden administration had awarded the chipmaker $8.9 billion that hadn't yet been paid out, and last year the Trump administration converted it into a roughly 10% stake.

The pattern isn't uniquely American, either. Germany's Proxima Fusion confirmed that the German government and the European Union sit on its cap table, alongside equity investments from government-backed funds SPRIND (the federal agency for disruptive innovation) and Deutsche Climate Tech Fonds.

Not every fusion startup has gone along. Thea Energy and Avalanche Energy, which hold federal awards and contracts, and Pacific Fusion, which partners with federal labs, confirmed they have not given the government a stake. Inertia Enterprises — which has a public-private partnership with Lawrence Livermore National Laboratory to commercialize fusion technology developed there — also said it has surrendered no equity.

Why the money matters more than the size

Fusion — generating power by fusing atoms together, as the sun does — demands exotic materials, sophisticated computer modeling and complex manufacturing. Private investors have bet more than $14 billion over the past decade that at least one company can put a fusion plant on the grid.

The Fusion Industry Association, the sector's trade group, says that's still not enough to win the race. Last year it asked the federal government for a one-time $10 billion infusion, with $5.4 billion earmarked for fusion startups. "Other nations are moving aggressively to accelerate their commercial fusion industries, pouring billions in state-backed efforts to win the race to fusion power," the CFS spokesperson said. "The $10 billion ask is designed to build out the research infrastructure in the DOE's Fusion Roadmap and be catalytic for the U.S. domestic fusion industry to compete with China."

Federal support had been a trickle until now. The Biden administration's Milestone Based Fusion Development Program at the Department of Energy pays companies as they hit technical goals, but it distributed less than $50 million in its first couple of years. Later awards grew slightly, yet stayed far short of the trade group's ask. Notably, the Fusion Industry Association's lobbying campaign never included equity-for-awards conversations, according to a person familiar with the matter — the stakes arrived as an unrequested condition, and the money flows from Commerce, not the research budget the group targeted.

So the lobbying is partly paying off: $260 million beats a trickle. But the equity strings weren't in the pitch, and VCs now face a harder calculation. A government stake could boost investor confidence in fusion as a strategic priority, or chill private money. Founders will have to weigh dilution, and cap tables get messy fast — who gets priority in pay-to-play rounds or a wind-down? Fusion companies have raised billions, but they'll need billions more to deliver. Federal awards used to be no-brainers at scale-up time. Now every founder and board has to run the math.
