Elon Musk is spearheading the construction of Terafab, a $16.8 billion semiconductor manufacturing facility in Grimes County, Texas. The project, announced this week, will create 3,000 jobs and become the largest building on Earth by floor space, surpassing the current record holder in Chengdu, China. Terafab aims to produce over one terawatt of compute annually, serving SpaceX and Tesla’s future chip needs, according to a press release from Texas Governor Greg Abbott and Musk’s statements on X.
The Terafab project will span 100 million square feet, more than five times the size of the world’s largest existing building, the New Century Global Center. Musk described the facility as a vertically integrated chip factory combining logic, memory, and advanced packaging under one roof. The first phase involves a capital investment exceeding $16.8 billion. Musk emphasized the scale and ambition of the effort in a press release, calling it the most epic chip-building initiative to date.
This development marks a significant expansion in domestic semiconductor manufacturing capacity, addressing the growing demand for advanced chips in automotive and aerospace sectors. Terafab’s integration of multiple chip production processes under one roof is designed to close the gap between current chip supply and future requirements. The facility is expected to support both SpaceX’s space technology and Tesla’s electric vehicle production, positioning Musk’s companies to control critical chip supply chains amid global shortages.
Texas Governor Greg Abbott highlighted the project’s economic impact, noting the creation of 3,000 new jobs. Construction timelines and further investment phases have yet to be detailed, but the scale of Terafab positions it as a landmark in U.S. semiconductor manufacturing infrastructure. The project’s website and Musk’s public statements provide ongoing updates on progress and milestones.
