Musk Announces a $20B Tesla and SpaceX Chip Factory in Austin
Elon Musk made a splash on Saturday, with the unveiling of Terafab, a joint chip manufacturing factory located in Austin, Texas and owned by Tesla, SpaceX, and xAI. It has, in fact, two factories — one for the chip on a Tesla vehicle and Optimus robot and another for AI satellites in space. Terafab is driving toward 2-nanometer chip tech and plans to manufacture one terawatt of compute per year. The project is expected to cost between $20 and $25 billion. No confirmation has been given on a construction timeline. Musk said existing chip suppliers are unable to scale fast enough to meet demand for all of his companies.
Elon Musk announced Terafab, a $20-$25 billion space factory in Austin, Texas, in partnership with Tesla, SpaceX, and xAI. It will manufacture 2-nanometer ships for land, vehicles, autonomous robots, and AI satellites for space deployment.
Key Highlights
- Elon Musk officially unveiled Terafab, a joint chip factory of Tesla, SpaceX, and xAI in Austin, Texas.
- Terafab will consist of two factories, one for car and robot chips, the other for AI satellites in space.
- The facility is designed for 2-nanometer chips and to produce one terawatt of computing power annually.
- The project will cost $20 to $25 billion, with a construction schedule yet to be provided.
Musk Debuts Terafab at Late-Night Austin Event
On Saturday night, at the old Seaholm Power Plant in downtown Austin, Elon Musk took the stage to announce what is likely one of his most ambitious manufacturing projects. He named it Terafab, a chip-manufacturing project that he called “by far the most epic chip-building exercise in history.”
Why Musk Says He Has No Choice But to Build Chips Himself
For years, Musk has been purchasing chips from TSMC, Samsung and Micron. He thanked all three at the event but said they are limited in how quickly they will expand, and that limit is well below what he needs.
This was his over-simplified view: “We either build the Terafab or we don’t get the chips, and we want the chips, which is why we build the Terafab.” The total AI computing output across the planet today is about 20 gigawatts a year, he said, but everything available now constitutes just 2% of what he requires in his companies.
What Terafab Will Actually Build
Terafab will combine two distinct factories in a single room, each factory producing only one chip design. One is for Tesla’s vehicles and Optimus humanoid robots. The other is a chip made specifically for AI satellites in space, engineered to withstand higher temperatures and harsher conditions than standard chips.
By placing design, fabrication, memory, packaging and testing all in one facility, all to produce 2-nanometer technology, which is the most advanced level entering commercialisation today. It eventually hopes to output one terawatt of computing power each year, roughly double the amount produced by the entire United States today.
The Money and the Doubts
Tesla’s chief financial officer confirmed the $20 to $25 billion cost estimate but said it was not yet included in Tesla’s existing 2026 spending plan, which already tops that figure at over $20 billion. No construction timetable has been made publicly available.
Musk has no background in chip manufacturing, and building one from the ground up is extremely difficult. TSMC spent years and more than $165 billion on its Arizona factories, which won’t have working 2-nanometer production until 2029. For context, Tesla’s AI5 chip is expected to enter small-batch production in 2026 (volume production was already delayed to mid-2027 before this announcement).
FAQs
- What is Terafab?
A joint chip factory in Austin, Texas, operated by Tesla, SpaceX, and xAI, is manufacturing two chips: one for cars and robots, and another for AI satellites.
- How much will it cost?
$20 to $25 billion, which are excluded from Tesla’s existing spending plan.
- Why is Musk is making his own chip factory?
He says TSMC, Samsung and Micron cannot grow quickly enough to serve him across all of his companies.
- What technology will it use?
2-nanometer chips, the most advanced chipmaking process in the world to go into commercial production.
