Elon Musk has finally unveiled one of his most ambitious ventures yet—the TeraFab—which the entrepreneur claims signifies the next monumental phase toward achieving a “galactic civilization.” The CEO of Tesla pointed out that only 2% of the required global computational capacity is currently being met on Earth, and this is precisely where TeraFab steps in.
The TeraFab facility is slated for construction in Austin, Texas, and will integrate the resources of Musk’s existing companies: Tesla, SpaceX, and xAI. Musk asserted that this factory will far surpass all current microchip production facilities:
“If you aggregate the output of every microchip fabrication plant currently operating on Earth, their combined production amounts to roughly only 2% of what TeraFab will be capable of manufacturing.”
TeraFab is planned to employ a 2-nanometer process technology and adhere to a principle of “rapid, recursive improvement,” wherein the design, fabrication, testing, and packaging of chips will all occur on unified production lines. Musk elaborated that, to his knowledge, no other facility globally integrates every stage—from logic and memory development through packaging, testing, and the creation and refinement of photomasks—in a single location. This integration allows for the establishment of a closed-loop, exceptionally fast cycle for chip enhancement.
According to Musk, 80% of the factory’s compute power will be allocated for space utilization, facilitated by Starship delivery systems and powered by solar energy. The initial high-volume product will be the AI5 chips designed for Tesla’s FSD systems, Robotaxi fleet, and Optimus humanoid robots. The remaining 80% of the off-world computing resources will be provided by the recently introduced D3 chips, engineered specifically for operation in harsh orbital environments. While acknowledging the vital role of existing suppliers, Musk highlighted the constraints on their current capabilities.
The revelation has garnered considerable industry attention, although many analysts harbor skepticism regarding the feasibility of the scale Musk has announced, given worldwide demand for lithography equipment and existing manufacturer bottlenecks. Among the technological pathways being rumored, a potential licensing agreement with Samsung for 2nm chip production is under discussion, though precise terms remain undisclosed.
