- Musk’s Terafab aims to exceed global chip production fifty times
- Recursive manufacturing promises speed without making technical details clear
- New physics claims remain undefined despite Musk’s high confidence
Elon Musk has revealed plans for a massive expansion of computing capacity through a new facility called Terafab in Austin, Texas.
The plant aims to generate one terawatt of computing power a year, eclipsing chipmakers’ current global output of around 20 gigawatts each year.
Musk stated that Tesla, SpaceX and xAI will collaborate to achieve this scale, producing chips versatile enough for various applications, including lithography masks.

A production system focused on speed and iteration
The Terafab initiative is based on a recursive manufacturing process that enables rapid chip production along with iterative redesigns for better performance.
Musk refers to “some very interesting new physics” underpinning this approach, expressing confidence in its viability even if timelines remain unclear.
“We’re going to push the limits of physics in computing and do some crazy, crazy things,” Musk said during a recent presentation.
Two main types of chips emerge from this effort: one optimized for inference tasks on Earth.
The former will primarily power humanoid robots that are projected to reach sales volumes of between one billion and ten billion units annually, and the latter is designed for space computers on satellites, starting at 100 kilowatts per unit and scaling to megawatt levels over time.
Musk anticipates that robots could eventually outnumber humans in a single year at maximum production rates, raising questions about feasibility given resource constraints.
In space, satellites equipped with these chips require enormous launch volumes; Musk’s calculations aim to deploy 10 million tons of material a year, including computer hardware, solar panels and support structures.
Such ambitions require a larger Starship variant, capable of carrying 200 tons per flight; However, basic arithmetic indicates that approximately 50,000 launches per year, or 135 per day, are needed to reach the terawatt goal.
Such activity amplifies vulnerabilities, including helium outages that already hamper semiconductor factories by 30% due to the US-Israel war in Iran.
Elon Musk did not provide a roadmap for sourcing amid these shortages, and his track record invites scrutiny; Remember Musk’s million self-driving Tesla taxis? Only 200 test units were produced.
SpaceX is also facing delays, with Starship V3 launches postponed even as boosters prepare for action.
However, Musk counters skepticism by recalling how Tesla’s electric vehicles and SpaceX’s reusable rockets overcame initial doubts about viability and profitability.
“I think it’s important to consider the greatness of the universe and what we can do that is much greater than what we have done before, rather than worrying about petty disputes on Earth,” he told an enthusiastic crowd.
