Elon Musk’s companies announce a joint $16.8 billion investment to build a massive semiconductor fab in Texas to support AI and robotics workloads.
Tesla and SpaceX have announced a joint $16.8 billion investment to build a new semiconductor fabrication plant, dubbed “Terafab,” in Texas.
Why a Terafab?
Both companies say the facility will produce high‑performance chips designed for artificial‑intelligence inference, autonomous‑driving workloads, and advanced robotics, reducing reliance on external suppliers.
Location and scale
The fab will be sited near Austin, leveraging Texas’ existing aerospace and automotive ecosystem, a skilled workforce, and favorable tax incentives.
Initial plans call for a 1.2‑million‑square‑foot campus capable of producing several hundred thousand wafers per month once fully operational.
Strategic benefits for Tesla and SpaceX
Tesla expects the in‑house chips to accelerate its Full Self‑Driving (FSD) stack and improve energy efficiency in its vehicle line‑up.
SpaceX aims to use the same silicon to power next‑generation Starlink satellites and onboard AI for autonomous spacecraft navigation.
Key technology focus
The Terafab will specialize in advanced node processes, including 3‑nm and emerging 2‑nm technologies, with an emphasis on low‑latency, high‑throughput AI accelerators.
- Custom AI inference cores for autonomous driving
- Radiation‑hardened processors for space applications
- Energy‑efficient chips for edge robotics
Construction is slated to begin later this year, with chip production expected to start in 2029.
