Terafab could become the largest factory on the planet—or Elon Musk’s biggest failure

The SpaceX and Tesla CEO sells the future in units of epic. The reveal of his 100-million-square-foot factory in Texas is his most ambitious vision yet. At last, we know how Elon Musk’s fabled Terafab will look. Tesla and SpaceX showed a video rendering of their jointly developed advanced chip factory on Thursday. It will occupy 100 million square feet in Grimes County, Texas, about 45 miles northwest of downtown Houston. The sci-fi-looking building is so vast that you could fit six of them in Manhattan. Musk, the CEO of both companies, took to X on Thursday to declare it “the largest and most valuable building on Earth by far.”
