Commonwealth Fusion lands $85M CHIPS Act award for fusion-ready chips
What's the deal? Commonwealth Fusion Systems (CFS) has signed a letter of intent for a proposed $85 million federal award from the US Department of CommerceDealroom has a profile for this one.

Try Dealroom → and grants the government a minority, non-voting stake in CFS.
What's the endgame? CFS is building Sparc, a demonstration reactor it aims to switch on next year, and the ARC commercial plant expected to deliver power to the grid in the early 2030s. The award backs five R&D efforts, including silicon carbide power electronics, radiation-hardened controls, and radio-frequency generators that heat fusion fuel.
Why now? Fusion startups are racing to complete first-of-a-kind reactors, but scaling to dozens of plants requires durable power electronics and a reliable supply chain. The grant targets both at once.
"Ultimately, that means a more capable, economical power plant and a stronger U.S. supply chain to build it," wrote Brandon Sorbom, co-founder and chief science officer at CFS.
By the numbers: The $85 million is part of a broader $389 million Commerce Department package for energy-related semiconductors, which also earmarks up to $175 million for Microsoft-backed fusion rival Helion. At that size, the award ranks among the largest 2% of all-time US deep tech grants.
What could go wrong? The award remains at the letter-of-intent stage and is not yet finalised. It supplements rather than drives CFS's balance sheet: the Google-backed company raised $1 billion in July and says it has raised roughly $4 billion overall.
The signal: Washington is backing the industrial supply chain, not just the reactor developers. By funding the chips, power electronics, and controls that commercial fusion plants will need, the government is betting on the ecosystem that could make fusion deployable at scale.
