Everything’s bigger in Texas: Musk’s planned $16.8 billion chip factory is five times bigger than the world’s current largest building

Elon Musk is betting that the next phase of his sprawling technology empire will require a building on a scale that has never existed before. SpaceX and Tesla are building Terafab, a 100-million-square-foot semiconductor manufacturing facility in Grimes County, Texas, more than five times the size of the world’s largest building.

“Terafab Texas will be the largest and most valuable building on Earth by far. And it will be stunningly beautiful,” Musk wrote on X. 

With about 18.9 million square feet of floor space, the New Century Global Center in Chengdu, China, currently holds the record for the world’s largest building. But Terafab is expected to exceed that quickly: “The first phase of the Terafab project represents a capital investment of more than $16.8 billion and will create 3,000 new jobs,” Texas Gov. Greg Abbott wrote in a press release.
