Musk Wants to Build a $25B Chip Factory — and Send Most of It to Space

Elon Musk just announced something called TeraFab. It's a $25 billion project between Tesla, SpaceX, and xAI to build their own chip factory in Austin.

The basic idea: instead of buying chips from other companies, Musk wants to make his own. One giant facility that handles the whole process from start to finish. They're going for the smallest, most advanced chips you can currently make — the same level that companies like TSMC in Taiwan are just starting to produce.

Two types of chips are coming out of this thing. One goes into Tesla cars and those Optimus robots. The other is built specifically to survive in space — designed to handle radiation and extreme temperatures so it can run on satellites.

Here's the part that really caught my attention. Musk says 80% of what this factory produces is going to space. Not Earth. Space. His argument is that solar power up there is about 5x stronger than what we get on the ground, and it's actually easier to cool electronics in a vacuum than it is here. So instead of fighting for land and power grid access to build massive data centers on Earth, just put them in orbit.

To put the numbers in perspective: he's targeting a terawatt of computing power per year. The entire US power grid produces about 1.2 terawatts total. He's basically saying he wants to match the whole country's power output, but in computer chips floating in space.

Now, is this actually going to happen? Musk has a long track record of announcing massive plans and then either scaling them back or taking way longer than promised. There's no construction timeline yet. And making chips at this level is incredibly hard — companies that have been doing it for decades still struggle with it.

But even the skeptics have to admit: if even a fraction of this works out, it changes who controls the chips that power AI. Right now, basically every AI company on the planet depends on one company in Taiwan for their best chips. Musk building his own factory — even a smaller version of what he's promising — starts to break that dependency.

Whether you think it's visionary or just Musk being Musk, the direction is worth watching.
