Elon Musk Announces TeraFab Project: Joint SpaceX, xAI and Tesla Initiative Targets Terawatt-Scale AI Compute

Elon Musk has unveiled the TeraFab, described as the most epic chip-building exercise in history and a project that will “take things to the next level” by orders of magnitude. The initiative is a collaborative effort between SpaceX, xAI and Tesla to deliver one terawatt of compute per year, an ambitious milestone positioned as essential for scaling civilization into a multi-planet and ultimately galactic species.

Current global AI compute output stands at roughly 20 gigawatts per year. According to Musk, the combined output of all existing semiconductor fabs on Earth represents only about 2 percent of the capacity required for the TeraFab target. While expressing gratitude to the existing supply chain including Samsung, TSMC and Micron and committing to purchase every chip they produce, Musk noted that their maximum comfortable expansion rate falls far short of the project’s needs. “We either build the TeraFab, or we don’t have the chips,” he stated. “And we need the chips, so we’re going to build the TeraFab.”

Construction begins with an advanced technology fab at Giga Texas in Austin. The facility will house, in a singl...
