Commerce Plans Up to $175 Million for Helion and $85 Million for Commonwealth Fusion Systems. It Is a Letter of Intent, Not an Award.

The U.S. Commerce Department announced on Oct. 22, 2026 that it signed four letters of intent for up to $389 million in research and development awards under the CHIPS and Science Act. Two of the four recipients are fusion energy companies, Helion and Commonwealth Fusion Systems (CFS), and the money is for a specific, unglamorous part of fusion: the chips and power electronics.

A letter of intent is a preliminary agreement. It says Commerce plans to make an award, and it does not commit the money until a final agreement is signed.

The Four Letters of Intent

According to the Commerce announcement as reported by Evertiq and Anadolu Agency:

• Helion: up to $175 million, for high-voltage power semiconductors and power modules for the high-peak-current pulsed power its fusion machines use.
• Commonwealth Fusion Systems: up to $85 million, for semiconductor R&D covering radio-frequency plasma heating, power electronics, embedded electronics for diagnostics, and radiation-hardened electronics.
• Vertical Semiconductor: up to $73 million, for vertical gallium nitride power chips for advanced computing, including a demonstration aimed at a 2.5-megawatt data center rack.
• Sibelco: up to $56 million, for purification technologies for ultra-high-purity quartz used in semiconductor manufacturing.

Commerce Secretary Howard Lutnick said the investments "expand domestic research, secure critical supply chains, and create high-paying American jobs." Bill Frauenhofer, the department's executive director of semiconductor investment and innovation, said the awards would help advance technologies for the grid, defense systems and fusion energy.

Helion's Details

Helion's own announcement says the expected award, up to $175 million, comes with $50 million in private investment, for a total of $225 million. The company says the high-voltage chips its pulsed power systems need are currently available only from overseas manufacturers, and the goal is to develop them domestically and move toward manufacturing, with higher efficiency, longer lifetimes and better cooling.

Helion's allocation, as it describes it:

• More than $100 million for semiconductor and advanced-packaging R&D in Everett, Washington, which the company says would bring more than 100 jobs and power module manufacturing capability to the state.
• About $80 million for tooling, design and process development with an industry partner in Burlington, Vermont.
• The remainder for packaging and manufacturing automation, with no amount given.

Helion CEO David Kirtley said building fusion power plants at scale "requires us to accelerate the development of technologies" such as these.

The Part That Is Easy to Miss: Equity

Helion's announcement says that once a definitive award agreement is signed, Commerce would receive a $175 million non-voting interest in Helion, priced from its most recent Series G valuation, as payment for the award. The Commerce description we read does not mention an equity stake, so we are relying on Helion's account of the structure. If accurate, this is closer to an investment than a conventional grant: the government would hold a financial interest in the company it funds.

CFS: What the Money Is For

CFS is building SPARC, a compact tokamak in Devens, Massachusetts, and has said it is targeting net fusion energy in 2027, as we covered in our fusion milestones guide. The $85 million would go to the electronics around the machine: the systems that heat plasma with radio waves, the sensors and control electronics, and parts built to survive radiation. The announcement we read gives no equity terms for CFS. Our report on CFS leading an AI digital twin of SPARC covers a separate federal award.

Why Chips

This section is analysis, not reporting.

Fusion headlines usually focus on plasma, magnets and lasers. But a pulsed fusion machine like Helion's repeatedly dumps large amounts of electrical energy, which makes power semiconductors a bottleneck. A supply chain that depends on overseas manufacturers for a critical part is a risk for any company planning to build power plants at scale, and Commerce is framing the awards in those terms. Placing the work in the Everett, Washington and Burlington, Vermont areas ties the money to local jobs, which is also part of the pitch.

Whether the chips deliver the efficiency gains Helion describes will only be known after the R&D is done. The funding pays for research, not for a finished product.

What We Cannot Conclude

We cannot say whether the letters of intent will become final awards, or on what terms. Helion's page gave no timeline beyond the announcement. Its funding history appears with two different numbers in the sources we read: Helion's announcement refers to a $500 million Series G, while a TechCrunch list reported $465 million raised in June. We did not resolve the difference. The sources we read do not give the locations or equity terms for the other recipients.

Why It Matters

• Fusion's bottleneck is hardware, not just physics. Power electronics are a critical, hard-to-source component.
• The government may become a shareholder. Helion's account of the structure includes a $175 million non-voting stake for Commerce.
• It is not final. Letters of intent can change before an agreement is signed.
• Two of the field's best-funded companies are in line. See our fusion company comparison.
