The U.S. Department of Commerce announced on 22 October 2026 four letters of intent for up to US$389 million of research awards under the CHIPS and Science Act. Helion is in line for up to US$175 million, Commonwealth Fusion Systems up to US$85 million, Vertical Semiconductor up to US$73 million and Sibelco up to US$56 million. As a condition of each award, the department will receive a minority, non-controlling and non-voting equity stake in the company. These are letters of intent, not final awards: the release describes the final awards only prospectively. The US$389 million is the sum of four ceilings, not committed money.

The coverage led on the obvious point, and it is right: the two fusion developers account for up to US$260 million, two-thirds of the round. Helion's award is for high-voltage power semiconductors and advanced energy power modules to power, control and harvest energy from its fusion generators' magnets. Commonwealth Fusion Systems' covers chips for radio-frequency plasma heating, power electronics, fusion diagnostics and radiation-hardened electronics. The equity condition is not new either. The desk reported in July that the program has tied its awards to government equity since December. What has moved is the layer. A research authority written for the chip industry is now lined up to finance the electronics that run a fusion power plant.

The other two letters sharpen that read. Vertical Semiconductor's award is for vertical gallium nitride power semiconductors for efficient power delivery in advanced computing, including a demonstration for a 2.5 megawatt data-center rack. Sibelco's is for purification and finishing technologies for ultra-high-purity quartz used in crystal-growth crucibles and semiconductor hardware, which is a materials chokepoint upstream of the wafer rather than a chip at all. Taken together, the round is aimed at power conversion at both ends of the power chain: the generator and the data-center rack.

The release states the department's aims as reducing reliance on overseas manufacturing for the grid, data centers, defense systems and fusion energy. It does not state a value for any of the four equity stakes, or how the stakes will be priced when the letters become awards. For a program now taking or negotiating stakes across the chip, quantum and power-electronics layers, that is the recurring silence: the government publishes the ceiling of what it may pay and not the size of what it will own.

Washington is using the chip law to buy into the power supply of computing, and until the stakes carry a price, the public can see the subsidy but not the shareholding it purchases.

What would change this read: a final award that drops or prices the equity condition in a way that makes the stake nominal rather than a real position.
