Elon put it plainly: “We either build the Terafab, or we don’t have the chips… and we need the chips, so we build the Terafab.” Today’s global chip industry is growing at only about 20% per year — nowhere near enough to support millions of Optimus robots (each needing far more chips than a car) and orbital AI data centers.
Massive investments are now going into: ✔️ Fully autonomous Cybercab robotaxis (production starting 2026) (维基百科) ✔️ AI & robotics (Optimus humanoid robot) ✔️ Next-gen AI chip production (Terafab project)
Wedbush analyst Dan Ives (one of the more credible voices covering Musk’s empire) has publicly predicted that Tesla and SpaceX will fully merge by 2027, calling Terafab the first step toward full integration.
This includes designing and manufacturing its own chips to power autonomous systems and robotics. At the center of this initiative is Physical AI Hardware, enabling tighter integration between software intelligence and real-world execution.
TERAFAB was announced publicly on March 21, 2026, in Austin, described as an unprecedented chip-building effort. Construction activity has been reported at the Giga Texas North Campus, with site preparation compared to early Gigafactory build phases.
According to Tesla's disclosure, the TERAFAB project is planned to have an annual production capacity of up to 100 billion to 200 billion advanced AI and storage chips, equivalent to a monthly wafer input of approximately 100,000 wafers.
... He said the so-called "Terafab" will have two facilities: one focused on AI chips for Tesla's electric vehicles and Optimus humanoid robots; while the other will be focused on AI chips for space-based data centers made by SpaceX.

Then there is advanced packaging, the facilities that stack HBM onto processors using 2.5D and 3D integration. These run $2 to $3.5 billion per phase, and TeraFab would need tens to hundreds of them.
The Terafab facility is projected to become the largest semiconductor manufacturing plant globally, significantly enhancing domestic chip production. The initiative aligns with the goals established by the CHIPS Act of 2022, which has prompted ...
It comes amid intensifying national efforts to reshore semiconductor manufacturing to the United States, driven by the CHIPS and Science Act signed into law in 2022, which allocated $52.7 billion in subsidies and incentives to domestic chip production. TSMC, Intel, and Samsung have all broken ...

When Elon Musk unveiled plans for a new semiconductor manufacturing facility he called 'Terafab', he promised it would be the 'most epic chip-building exercise in history.' However, industry experts are doubtful that Musk can actually execute on the scale and scope he described, which would require up to $13 trillion in capital spending to build 140-360 new chip factories.
By vertically integrating chip production, Musk can ensure a reliable supply of the specialized semiconductors needed to push the boundaries of self-driving capabilities. Musk’s vision for Terafab includes powering a network of satellite-based data centers, which could potentially render traditional, land-based data centers obsolete.
The goal of Terafab is to produce 1 terawatt of computing power annually, while the current global annual output of AI computing power is about 20 gigawatts. That is to say, Terafab's goal is 50 times that amount. Musk's logic is straightforward - if Samsung, TSMC, and Micron expand production at full capacity, he is willing to "buy all the chips".
The CHIPS and Science Act aims to bring manufacturing back to the U.S. by offering incentives to chipmakers. That’s brought new investments from TSMC, Intel, and Micron, plus projects like TSMC’s Arizona fabs and Elon Musk’s private Terafab ventures.
