The Commerce Department signed seven letters of intent under the CHIPS research and development programme on 29 July, worth $874 million in total. The structural news is not the money. It is that the government is taking equity.
The GlobalFoundries terms
GlobalFoundries signed for $300 million to accelerate US silicon photonics, covering work at Malta, New York and Burlington, Vermont. In exchange, Commerce takes roughly 1% of the company. Silicon photonics matters here for a specific reason: as accelerator clusters grow, the interconnect between chips becomes the bottleneck, and moving that interconnect from copper to light is the main answer on offer.
The other two disclosed
Kepler takes $245 million for AI memory — the category the current shortage has made strategically acute. Extropic takes $75 million for thermodynamic sampling units, a genuinely unconventional bet: hardware that computes with physical noise rather than suppressing it, aimed at probabilistic workloads.
What a letter of intent is not
These are not disbursements. A letter of intent precedes negotiated definitive agreements, and CHIPS awards have historically taken months to close and have been restructured between announcement and signature. Nothing here has been paid.
The precedent
Taking equity converts industrial policy into a shareholding, and a US government position on the capitalisation table of a foundry it also regulates and buys from. That is a different instrument from a grant, with a different set of conflicts — and having been used once at this scale, it becomes the template for what follows.
