> SpaceX and Tesla just announced a semiconductor megafactory in Texas that would dwarf every building on Earth, but the gap between what is legally committed and what Elon Musk is promising raises a question worth asking before the groundbreaking.

_On August 6, 2026, **Tesla** ([NASDAQ:TSLA](https://finance.yahoo.com/quote/TSLA/)) and SpaceX formally confirmed Terafab, a jointly built semiconductor megafactory in Grimes County, Texas, just north of Houston. On X, Elon Musk called it “the largest and most valuable building on Earth by far.” The site plans exceed 100 million square feet of manufacturing space, more than five times China’s New Century Global Center and larger than the Pentagon, Apple Park, and Mall of America combined._

_The pitch is vertical integration at a scale nobody has attempted. Terafab will house manufacturing, packaging, and testing of advanced logic and memory chips in a single facility, aimed squarely at the bottleneck Musk keeps hitting: there are not enough chips on Earth to build the Optimus robots, Cybercabs, and space-based data centers he has pitched investors. SpaceX describes the plant as designed to “bridge the divide between current global chip supply and the compute demand of the future”, with a stated production goal of more than 1 terawatt of compute per year optimized for edge inference._
