SpaceX and Tesla announce Terafab Texas, a $16.8 billion semiconductor manufacturing megaproject. Elon Musk describes it as 'the largest and most valuable building on Earth.'

Terafab is positioned to close the gap between today's chip production and the demand of the future, particularly as applications extend into space. Terafab Texas will be the largest and most valuable building on Earth by far, designed with striking architectural beauty.

Sequoia Capital's Shaun Maguire has underscored Terafab's significance for Tesla and Elon Musk's broader vision, noting that market participants are underestimating the likelihood of success. "People are assigning way too low of a probability that it will work. I feel confident that it will," Maguire stated. He emphasized that Terafab matters in part because it achieves supply chain ownership, providing visibility into production capabilities and direct control over a critical input.
