The U.S. Department of Commerce announced on October 22, 2026, four letters of intent for up to $389 million in CHIPS Act research funding. The proposed awards target power semiconductors for fusion energy and AI infrastructure, plus ultra-high-purity quartz essential to semiconductor manufacturing. These are proposed awards, not finalized or disbursed grants.

Key Takeaways

• Four companies signed letters of intent totaling up to $389 million.
• Fusion power electronics, vertical gallium nitride and semiconductor-grade quartz are the priorities.
• The government would receive minority, non-controlling, non-voting equity interests if final agreements are reached.
• Award amounts, schedules and technical outcomes remain conditional.

Four Proposed CHIPS Awards

Recipient	Proposed federal award	Research focus
Helion	Up to $175 million	High-voltage pulsed-power devices and fusion modules
Commonwealth Fusion Systems	Up to $85 million	Radio-frequency heating, control and fusion electronics
Vertical Semiconductor	Up to $73 million	Vertical GaN power transistors for advanced computing
Sibelco	Up to $56 million	Ultra-high-purity quartz processing and finishing

Why These Devices Matter

Helion requires precisely switched high currents to drive and recover energy from fusion magnets. Commonwealth Fusion Systems is developing electronics for plasma heating, diagnostics and plant control. Its earlier engineering update below illustrates its SPARC hardware; the video predates this funding announcement.

Vertical Semiconductor proposes vertical GaN technology for a claimed 2.5 MW AI rack demonstration—a development target, not a demonstrated commercial rack. Sibelco’s quartz research supports crystal-growth crucibles and precision manufacturing components.

Power conversion losses ultimately become heat. That makes semiconductor packaging, switching performance and supply materials relevant to data centers as well as experimental energy plants. See our reporting on GaN in servers, 800 V rack power, and atomic-scale chip manufacturing.

Inside Fusion Power Engineering

This earlier Helion technology explanation describes magnetic compression and energy recovery. Its official Polaris video provides engineering background, not evidence of commercial fusion electricity delivery or completion of the proposed chip research.

What Happens Next

Final awards require negotiations and approvals. The Commerce Department release says the government would take non-voting equity stakes in each recipient. The measurable milestones will be finalized terms, independently demonstrated semiconductor performance and domestic research or manufacturing capacity—not the announced dollar figures alone.

An October 22 public fusion-community discussion provides additional social context; the government and company releases remain the factual sources.
