Commerce Pledges $389M for AI and Fusion Power Semiconductor R&D

By Priya Raman

The U.S. Department of Commerce has pledged $389 million to Helion, Commonwealth Fusion Systems, Vertical Semiconductor and Sibelco for power-semiconductor work serving commercial fusion and AI data centers.

Commerce issued letters of intent to the four companies on October 22 under the CHIPS and Science Act, a 2022 law that Congress backed with a $10 billion semiconductor-research fund. According to the National Institute of Standards and Technology, the awards should fund semiconductor and materials technologies for power regulation, conversion and distribution in grid, defense and data-center applications.

Commerce Secretary Howard Lutnick said: “The Trump Administration is accelerating American semiconductor innovation to enhance our domestic energy and power resources.” Reuters, which first reported the awards, counted 19 similar R&D grants issued in recent months.

Where does the $389 million go?

• Helion: Up to $175 million for high-voltage power semiconductors and energy modules that create the magnetic field in its fusion reactors. The Everett, Washington, company also expects $50 million in private funding alongside a definitive award, bringing that package to $225 million.
• Commonwealth Fusion Systems: Up to $85 million for radio-frequency plasma-heating semiconductors, power electronics, fusion diagnostics and radiation-hardening technology. The Massachusetts company links the work to global fusion deployment.
• Vertical Semiconductor: Up to $73 million for vertical gallium-nitride power chips for AI server racks. The MIT spinout’s program includes the National Institute of Standards and Technology’s reported development of the first 2.5-megawatt data-center rack.
• Sibelco: Up to $56 million for high-purity quartz used in chip production.

Helion said Commerce would take a non-voting $175 million interest priced against its Series G, which valued the company at $15.5 billion; TechCrunch put the stake at about 1%. CEO David Kirtley said: “Deploying fusion power plants at scale will require that we accelerate the development of certain technologies, such as semiconductors.”

Commonwealth Fusion Systems CEO Bob Mumgaard said the funded innovations would be important to the company’s effort to build global deployment of fusion. The source provides detailed equity terms only for Helion, leaving the equivalent pricing for the other three recipients unspecified.

What does this mean for AI hosting?

Several Bitcoin miners have spent the last two years acquiring data-center space and electricity for AI clients, part of a broader revenue-diversification strategy built around high-performance computing. The source names no miners and gives no capital-spending, power-contract or deployment figures, so the scale of that shift remains unverified.

The connection to the awards operates on two timelines. Vertical Semiconductor’s gallium-nitride work concerns rack-level power conversion for current AI workloads; Helion’s fusion program targets a later source of competitively priced electricity. The source argues miners would be natural customers once commercial plants deliver it, but discloses no purchase agreement.

Bitcoin miners compete on cost per hashrate, while AI hosting carries comparable pressure on power efficiency and cooling. Better conversion chips and, later, fusion supply could reduce one of the largest costs shared by both enterprises. The source provides no measured efficiency gain, electricity price, plant schedule or customer contract, so those benefits remain projections rather than operating results.

Why do the equity stakes matter?

Each grant carries a non-controlling, non-voting federal equity interest. That condition breaks with earlier non-dilutive federal grants, which did not touch recipients’ capitalization tables, although Commerce used the same equity structure in deals with MP Materials, USA Rare Earth and Intel.

The new federal amounts remain small relative to private capital: Commonwealth has secured about $4 billion, Helion has $3.2 billion in committed capital, and TechCrunch reports more than $14 billion invested across the fusion sector.

The Fusion Industry Association has requested $10 billion in one-time government funding for the industry, including $5.4 billion for startups. For venture investors, the policy question is whether dilution is acceptable in exchange for a national strategic signal that fusion has become an important technology for the country. For miners, the commercial question is where grid economics move next.

What should R&D managers track?

Managers should separate the award announcements from validated performance. The source reports a 2.5-megawatt rack and several development targets, but no chip efficiency, yield, reliability, delivery schedule, plant output or contract price.

The next checkpoint is conversion of the October 22 letters of intent and award ceilings into funded programs with disclosed technical and commercial milestones.
