Tesla·SpaceX Terafab semiconductor supply chain — 10 Korean firms under NDA · $16.8B Phase 1 · 100M sq ft Texas campus
Published · Updated · By Investus editorial desk (SUNRYU Partners)
Tesla and SpaceX are in talks with ~10 South Korean semiconductor suppliers for the Terafab manufacturing complex in Grimes County, Texas — more than half have already signed NDAs. Discussions cover chipmaking materials, process equipment, valves/piping, testing components, and advanced packaging. Terafab Phase 1: $16.8B+ investment, 100M sq ft semiconductor campus. Musk: 'output from a single building will rival the GDP of a top-20 country.'
What Happened
Tesla and SpaceX are in active talks with ~10 South Korean semiconductor suppliers to build the Terafab supply chain in Grimes County, Texas. More than half have signed NDAs. Topics: chipmaking materials, process equipment, valves and piping, testing components, advanced packaging.
Terafab overview: $16.8B+ Phase 1 investment; 100M sq ft semiconductor campus; 3,000+ jobs; Musk: 'The value of Terafab's output will place it in the top 20 of country GDP in a single building.' Groundbreaking imagery confirms the project is moving from planning to construction.
Korea was selected for its world-class capabilities in memory, advanced packaging, and process equipment — centered on Samsung and SK Hynix but extending to equipment and component suppliers.
More Context
Why both companies need their own chips:
- Tesla: Dojo supercomputer chips, FSD inference chips, Optimus AI processing
- SpaceX: Starlink satellite payloads, Starship flight control, SI AI inference infrastructure
A merged TSLA-SPCX would consolidate both demand streams into one Terafab sourcing funnel — maximizing scale economics and vertical integration from design through packaging. This reduces dependency on TSMC, Samsung Foundry, and other external fabs.
Key View
Terafab is the clearest signal that Tesla and SpaceX intend to build a self-contained industrial ecosystem spanning semiconductors, AI, robotics, and space. Korean supplier partnerships are the first stage of supply chain internalization. At $16.8B Phase 1, Terafab represents long-term option value embedded in TSLA and SPCX.
