SpaceX and Tesla are co-investing $16.8 billion in a Texas chip facility called Terafab to secure dedicated silicon for AI, robotics, and space-based data centers — one of the largest announced private semiconductor investments in the US.

Details

SpaceX and Tesla are jointly committing $16.8 billion to a chip manufacturing facility in Texas called Terafab, according to AI Business. The stated goal is to secure dedicated chip capacity for AI workloads, robotics, and space-based data center applications across Elon Musk's portfolio of companies. The source article provides limited detail beyond the headline investment figure and stated rationale. It is not confirmed whether Terafab will operate as a fabless design house partnering with TSMC or GlobalFoundries, or whether it involves on-site fabrication. At $16.8B, the scale is comparable to major national semiconductor investments by Intel or Samsung under fab-expansion programs. If confirmed at this scale, Terafab would represent a significant move toward chip supply independence for xAI, Tesla's FSD stack, and Starlink's ground processing — reducing dependency on NVIDIA and AMD. The article does not confirm xAI's inclusion in the investment or provide a timeline for the facility. Given the thin source content, specific details should be verified against primary announcements.
