The other day when the US's stake in Intel was announced, people assumed it was a political stunt. I suspected it was because of national security interests. The CHIPS act probably didn't get the result US Defense wanted quickly enough. Some details that were glossed over include that there was a chip shortage a few years ago as a result of COVID and TSMC supply chain disruptions that led to a shortage in electronics…
The real reason is simple, if you've been following IFS: Intel's foundry has no large customers. The free market has spoken and almost every single customer prefers TSMC or Samsung silicon. America was boxed-out of serious world-class chip manufacturing ever since Intel swerved on EULV. If it was for natsec reasons then I doubt the fed would waste their time taking a passive seat when they could claim Intel as eminent domain.
It's not about national security whatsoever; this is part of a last-ditch effort to force Apple and Nvidia to buy American silicon.
