Elon Musk announced that his Terafab project, a plan to manufacture custom chips for Tesla, SpaceX, and xAI, will be built in Austin, Texas. The facility will start with an 'advanced technology fab' that can produce chips of any kind and test them, before eventually scaling up to support a terawatt of computing power per year.
Why it matters
Musk's chip project is a bold move to address the semiconductor shortage that has impacted his companies' ability to meet their growing needs for computing power in areas like robotics, AI, and space data centers. If successful, it could help solidify Texas' status as a chipmaking hub and give Musk more control over his supply chain.
The details
The Terafab facility will initially produce chips optimized for edge computing and inference, primarily for Tesla's vehicles, robotaxis, and Optimus humanoid robots. It will also make high-power chips designed for space applications that could be used by SpaceX and xAI. Musk plans for the facility to eventually support a terawatt of computing power per year, a massive scale that would require significant investment and technological breakthroughs.
- Musk announced the Terafab project in a presentation in downtown Austin on March 22, 2026.
- SpaceX is expected to hold an IPO later this year to raise funds for building and launching AI data centers in space.
The players
Elon Musk
The CEO of Tesla and SpaceX, who is spearheading the Terafab chip project.
Tesla
Musk's electric vehicle company, which will jointly run the Terafab facility with SpaceX.
SpaceX
Musk's private space exploration company, which will also be involved in the Terafab project and is planning an IPO to fund its space-based AI data centers.
xAI
An AI company acquired by SpaceX in February 2026, which is expected to use the majority of the chips produced at the Terafab facility.
Greg Abbott
The Governor of Texas, who was present at Musk's announcement event in Austin.
What they’re saying
“We either build the Terafab or we don't have the chips, and we need the chips, so we build the Terafab.”
— Elon Musk, CEO, Tesla and SpaceX
“The future I want to see: I want us to live long enough to see the mass driver on the moon, because that's going to be incredibly epic.”
— Elon Musk, CEO, Tesla and SpaceX
What’s next
SpaceX is expected to hold an IPO later this year to raise funds for building and launching AI data centers in space.
The takeaway
Musk's ambitious Terafab chip project in Texas is a bold move to address the semiconductor shortage impacting his companies and give them more control over their supply chain. If successful, it could solidify Texas' status as a chipmaking hub and enable Musk's vision for advanced AI and space-based computing.
