Musk Launches Terafab Chip Fab Project

[Company Update] Musk announced that Tesla and SpaceX will jointly build two 2-nanometer chip fabs.

Core Development: In-House Wafer Fabs to Overcome Compute Bottlenecks

On March 22, 2026, Musk revealed on X that his companies will launch a high-end chip manufacturing initiative named Terafab in Austin, Texas, comprising two wafer fabs—one dedicated to Tesla vehicles/humanoid robots and the other to space-based AI data centers. He emphasized: “Build it, or face a future with no chips at all.”

Key Metrics: Demand Far Outstrips Global Supply

Musk stated that current global chip capacity meets only “a small fraction” of his future needs. Terafab aims to deliver 1 terawatt of computing power annually, with a projected budget of $20–25 billion. Although no timeline for completion has been disclosed, the move directly reflects deep concerns over reliance on foundries like TSMC and Samsung.

Strategic Foundation: Building a Vertically Integrated Compute Empire

The project seeks full-stack control—from chip design to interplanetary computing—to support Musk’s vision of a “multiplanetary civilization.” While expressing gratitude to existing suppliers, Musk bluntly asserted that his companies’ combined demand will eventually exceed total global chip production.
