Musk unveils $20B TeraFab chip project

On March 22, 2026, Musk said Tesla and SpaceX want to build TeraFab, a joint semiconductor campus in Austin that would keep more of the chip stack on one site. He cast it as a way to feed Tesla vehicles, Optimus robots, and space compute, but gave no production timeline and said the companies will still buy chips from TSMC, Samsung, and Micron.

// ANALYSIS

Hot take: this is a vertical-integration moonshot first and a fab plan second. If TeraFab ever gets built, it could shorten chip iteration loops for Musk's hardware stack; if not, it still signals how badly Tesla and SpaceX want to control their AI silicon destiny.

–A single-campus flow from chip design through packaging and test would cut a lot of handoffs.
–The 100 to 200 GW terrestrial target, plus the space-compute vision, looks like a long-range aspiration, not a near-term schedule.
–The hard parts are process control, yields, tooling, and semiconductor talent; money alone does not solve those.
–Keeping TSMC, Samsung, and Micron in the mix makes TeraFab a hedge, not a replacement.
