other · 2026-05-06

Elon Musk's SpaceX, which also includes his AI venture xAI, is exploring the possibility of establishing a semiconductor manufacturing plant in Grimes County, Texas. This initiative, known as 'Terafab,' could start with an investment of $55 billion and reach a total of $119 billion. It is envisioned as a multi-phase facility for advanced computing and vertically integrated semiconductor production. Musk has previously discussed collaborations with Tesla and Intel to create chips for various applications, including AI servers and autonomous vehicles. The goal is to generate 1 terawatt of power annually through chip production. Musk indicated that Grimes County is among several potential sites, as he aims to meet the computing demands for xAI’s Grok AI models. The combined valuation of SpaceX and xAI is $1.25 trillion, with plans for a public offering in June.
