Elon Musk is building the largest AI chip factory ever conceived — and it could cost $119 billion

This proposed AI chip fabrication facility, codenamed TeraFab, represents a significant expansion of Elon Musk's industrial ambitions beyond his existing automotive and aerospace ventures. The sheer scale of the project, envisioned as a sprawling complex in Texas exceeding 100 million square feet, suggests a monumental undertaking in semiconductor manufacturing. The aim is to produce AI chips internally, potentially for use across Musk's various companies like Tesla and SpaceX, which increasingly rely on advanced computing for autonomous driving, rocket guidance, and other sophisticated technologies.

The potential cost of $119 billion highlights the immense capital required for such an endeavor, positioning it as one of the largest manufacturing investments in history. Establishing such a significant domestic chip production capability could have far-reaching implications for the semiconductor industry, potentially altering supply chains and driving innovation in AI hardware. This move signifies a strategic effort to secure proprietary chip supply and exert greater control over the development of artificial intelligence across Musk's diverse enterprises.
