Elon Musk Says Tesla and SpaceX Plan Austin AI Chip Facility
The proposed "Terafab" in Austin would include separate fabrication sites for Tesla’s AI needs and SpaceX’s space-based data center plans, according to Elon Musk.
Fact Check
The statement accurately reflects a major announcement made by Elon Musk on March 21, 2026. Multiple news outlets (Electrek, Fortune, Reuters) confirm the 'Terafab' project in Austin, the $20-25 billion investment, and the joint involvement of Tesla and SpaceX to produce AI chips for terrestrial and space-based applications. The detail regarding 'separate fabrication sites' aligns with reports of a massive complex (100 million square feet) housing distinct production lines for the different companies' specific chip architectures (e.g., Tesla's AI5/AI6 vs. SpaceX's D3 orbital chips).
