The facility will develop space‑hardened chips, which are essential for satellite technology that must withstand extreme conditions such as high radiation levels and intense heat.
40 percent of everything ever launched from Earth is a SpaceX satellite currently in orbit. And then there’s the TeraFab. The Austin facility will house equipment for logic, memory, packaging, testing, and lithography mask production in a single building in order to produce chips for Tesla's vehicles and Optimus humanoid robots, plus higher-power chips hardened for the space environment.
Elon Musk took the stage over the weekend to announce a new partnership between Tesla, SpaceX and xAI to build a $25 billion chip-making factory in Austin, Texas, called Terafab. Acknowledging Samsung, TSMC and other chipmakers, Musk said the ...
On the night of March 21, 2026, ... tonight around 8pm CT. The goal is to produce over a TERAWATT of compute per year (logic, memory & packaging) with ~80% for space and ~20% for the ground.”...
Global AI compute capacity today sits at approximately 20 gigawatts per year across all facilities worldwide. TERAFAB’s one-terawatt target is 50 times that figure, a scale that surpasses every semiconductor fab on the planet combined, which currently accounts for roughly 2% of TERAFAB’s annual compute goal.
Speaking in Austin, Musk described the Terafab concept as an effort to materially expand computing supply for artificial intelligence, robotics and space applications, areas he indicated may require far more silicon than is currently available. Estimates referenced by analysts suggest the project could involve $5 trillion to $13 trillion in capital spending, supporting hundreds of fabrication plants and targeting up to one terawatt of annual compute capacity, a scale that may rival or exceed tod

Positive Sentiment: TeraFab / AI chip narrative draws bullish analyst support — Wedbush and others continue to call Tesla an emerging AI/semiconductor play after the Terafab chip-factory effort, which boosts the company’s long-term “physical AI” thesis. Dan Ives: Terafab Upside
Elon Musk unveiled an ambitious plan Saturday night to build what he calls the world’s largest semiconductor manufacturing complex in Austin, Texas — a joint venture between Tesla, SpaceX and xAI he is calling “Terafab.”
Terafab is expected to accelerate Tesla and SpaceX's AI development by ensuring chip and memory supply, helping the companies overcome current constraints and enabling ambitious AI projects like FSD, Cybercab, and Optimus.
ASML, Applied Materials, Lam Research, and KLA dominate critical manufacturing process steps. Additionally, Micron, Samsung, and SK Hynix provide advanced memory dies. Therefore, TeraFab must place multi-billion-dollar orders years in advance. So far, public filings show no firm purchase orders for EUV or immersion lithography tools.
Musk admitted that partners like Samsung and TSMC couldn't meet the scaling speed requirements. Therefore, Tesla decided to build its own TeraFab to ensure a reliable chip supply. Experts warn the project faces major challenges, particularly the supply of EUV lithography machines from ASML ...
A 2nm fab requires multiple High-NA EUV lithography systems from ASML. These machines cost hundreds of millions of dollars and have waitlists that span years. We have not seen any confirmed orders from Tesla in the ASML backlog yet. The clock for a fab does not start when a press release is issued; it starts when the equipment slots are secured. Furthermore, a facility like Terafab requires thousands of specialized engineers.
A recently issued research note ... by 2027. Ives argues that the groundwork is already actively being laid and points to the newly announced Terafab project as the ultimate catalyst for this historic combination....
Positive Sentiment: Wedbush analyst Daniel Ives reiterates a bullish view on Tesla and calls the Terafab chip push “an emerging AI powerhouse,” supporting upside thesis for Tesla’s AI/robotics roadmap and the stock’s re-rating.
Musk concluded his Terafab presentation with a video showing future data center satellites being built on the Moon and launched using the electromagnetic mass driver.
Terafab is a $25 billion chip manufacturing facility that Musk said will be capable of producing 1 terawatt per year in computing power. At that rate of output, it would be the largest semiconductor fab in the world, by a lot.
