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.
He sees something much bigger than "buying chips." Lay out the cards in his hand: Tesla has millions of vehicles and robots on the ground. xAI has the Grok large model. SpaceX has rockets to send things into space. Starlink has a global satellite network to beam data back to Earth from the sky. Now Terafab adds the final piece—chip manufacturing.
Elon Musk has announced the construction of Terafab, a $25 billion chip manufacturing facility aimed at challenging NVIDIA's dominance in the AI chip market. The facility will produce 2-nanometer chips, with the first product, the Tesla AI5, ...
... 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.
Developed in partnership with SpaceX and xAI, the project aims to produce advanced two-nanometer (2nm) chips in-house, marking a bold push toward full vertical integration of AI infrastructure.
An example is his recently unveiled Terafab project to build a massive chip factory that will require the efforts of Tesla, SpaceX, and xAI. Merging SpaceX with xAI will enable Musk to consolidate the two companies' efforts and more easily unify ...
Musk's TeraFab dream meets Nvidia reality check on chip manufacturing limits

After criticizing leading chipmakers for slow capacity expansion and claiming his companies need 100 – 200 billion AI processors annually, Elon Musk last week unveiled
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.
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.
Development Elon Musk announces 'largest chip manufacturing facility' Terafab coming to Austin
Ives calls the Terafab the "first step" toward full operational integration between the two companies.
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.
The company was forced to reintroduce human labor at critical steps. Battery manufacturing provides an even closer parallel. Despite ambitious targets set at Battery Day 2020, progress on 4680 cells has been slower and more difficult than expected. Manufacturing, particularly at scale, resists simplification. Semiconductor fabrication is more complex still. Comparing TeraFab to a conventional fab and concluding that it fails misses the point.
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.
NVIDIA’s CEO Jensen Huang cautioned that constructing advanced fabs is “extremely hard”—not merely assembling equipment but mastering complex physics, process control, and yield engineering developed over decades[4]. Meanwhile, some ...
On March 23, 2026, Reuters reported that CEO Elon Musk said the day before that Tesla, Inc. (NASDAQ:TSLA) and SpaceX aim to establish two advanced chip factories in Austin, Texas, as part of the “Terafab” project.
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....
The survey identifies three primary blockers: data preparation/availability for AI (74%), governance and compliance concerns (48%), and software interoperability challenges (42%).
A modern leading-edge 2nm-class logic fab costs roughly $25 billion to $35 billion. And while the economies of scale drive costs down, we are still talking about a $30 billion ballpark per fab, which means about $3.15 trillion for logic fabs ...
