Terafab will be 50× the size of the Pentagon when complete

Posted Aug 7 2026, quoting a size-comparison image of xAI's planned 'Terafab' — a massive semiconductor fabrication megastructure to supply the company's AI-compute and robotics chips. The Pentagon covers ~6.5 million sq ft of floor area, so 50× implies a facility on the order of 300+ million sq ft when complete. No completion date has been given, so this is tracked as a no-deadline forward claim resolving whenever Terafab is built out.
