Tesla and SpaceX Announce $16.8 Billion Terafab Semiconductor Factory in Texas
AI compute capacity expands with major datacenter deals and a new semiconductor fab, as hyperscalers commit billions to infrastructure and power solutions.
The story
The physical build-out of AI infrastructure saw significant movement this week, led by Tesla and SpaceX's official confirmation of their Terafab semiconductor factory in Grimes County, Texas. This massive facility, slated to be over 4 miles long and span more than 100 million square feet, represents an initial investment of $16.8 billion. Construction is planned to begin on December 1, 2026, with completion expected by the end of 2028. The Terafab aims to integrate logic chips, memory, packaging, and testing on a single site to produce AI chips at scale for both terrestrial and space applications, powering Tesla's Optimus robots and Cybercabs, as well as SpaceX's planned space-based data centers.
Elsewhere, Anthropic secured a substantial $45 billion, six-year agreement with Nscale for approximately 460 megawatts of compute capacity at the Monarch Compute Campus in Mason County, West Virginia. This deal grants Anthropic access to the first of three planned buildings at the 2,250-acre campus. Microsoft, meanwhile, received the first phase of an AI data center in Texas from IREN, featuring direct-to-chip liquid cooling, with IREN targeting 480 MW of AI cloud capacity in 2026. These developments underscore the industry's rapid scaling and the increasing focus on integrated power and specialized hardware for AI workloads.
