Overview
- Musk unveiled the joint Tesla–SpaceX–xAI Terafab concept in Austin on Saturday, pitching a vertically integrated chip complex with two fabs, 2‑nanometer targets, and dedicated AI5 chips for cars and robots plus D3 chips for space.
- Bernstein on Thursday estimated that reaching Musk’s 1 terawatt‑per‑year compute ambition could require hundreds of fabs and roughly $5 trillion, far beyond his $20–25 billion figure.
- Tesla’s CFO said the $20–25 billion estimate is not in the company’s 2026 capital plan and no construction timeline was provided, while independent estimates such as Morgan Stanley’s place likely costs closer to $35–45 billion.
- Analyst reaction split the Street, with Wedbush’s Daniel Ives calling Terafab a first step toward a Tesla–SpaceX merger he expects in 2027 as Barclays’ Dan Levy warned spending could run many multiples above even a $50 billion bull case.
- Musk has floated a footprint about 10 times Giga Texas that would need thousands of acres, and he clarified a smaller Austin building shown in slides is only an advanced R&D fab as several full‑site locations remain under review.
