On a Saturday night time in Austin, standing inside a defunct energy plant, Elon Musk delivered a message that lower straight to the guts of the AI chip scarcity: His firms can not get the chips they want, so they will construct their very own.
Musk shared on March 21 that Tesla, SpaceX, and xAI are launching a three way partnership known as Terafab, a semiconductor fabrication facility to be constructed adjoining to Tesla’s Giga Texas campus in Austin. The mission is estimated to price between $20 billion and $25 billion, in response to Electrek.
“We either build the Terafab, or we don’t have the chips, and we need the chips, so we build the Terafab,” Musk mentioned throughout a livestream broadcast on X (the previous Twitter).
What Terafab is designed to do
The ability goals to provide chips consuming 1 terawatt of compute energy per 12 months, making it by far the most important semiconductor manufacturing ambition ever deliberate.
Musk outlined two kinds of chips the ability would produce.
One is optimized for edge inference and designed to energy Tesla’s Full Self-Driving software program and its Optimus humanoid robots. The opposite is hardened for the house surroundings and meant for SpaceX’s deliberate community of orbital knowledge facilities, in response to Knowledge Middle Dynamics.

When it comes to compute output, Musk projected 100 to 200 gigawatts per 12 months on the terrestrial facet, with the rest of the 1 terawatt goal going to space-based AI compute aboard solar-powered satellites.
The ability targets 2-nanometer course of know-how, presently the forefront of the semiconductor business, and is designed to consolidate chip design, lithography, fabrication, reminiscence manufacturing, superior packaging, and testing underneath a single roof.
Preliminary output is about at 100,000 wafer begins monthly. The total-scale goal is 1 million wafer begins monthly, which Electrek famous would characterize roughly 70% of TSMC’s whole present international output, from a facility operated by firms which have by no means fabricated a chip.
Why Musk says he has no selection however to construct semiconductor fabrication facility
Musk’s argument facilities on scale. He mentioned all the present fabrication amenities on Earth produce solely about 2% of what Tesla and SpaceX will ultimately want for autonomous autos, humanoid robots, AI coaching clusters, and space-based compute programs.
He described the worldwide chip business as unable to increase shortly sufficient to fulfill demand, whereas expressing gratitude to present companions, together with TSMC, Samsung, and Micron, saying he would really like them to increase as shortly as they will, in response to Knowledge Middle Dynamics.
Tesla’s AI5 chip is among the many first merchandise the pilot facility is designed to provide, with small-batch manufacturing anticipated in 2026 and quantity manufacturing in 2027.
Key Terafab specs unveiled:
- Location: Adjoining to Giga Texas, japanese Travis County, Austin
- Estimated price: $20 billion to $25 billion, in response to Electrek
- Goal output: 100 to 200 gigawatts per 12 months of terrestrial chips; as much as 1 terawatt together with house chips
- Course of node: 2-nanometer know-how
- Preliminary wafer begins: 100,000 monthly, scaling to 1 million at full capability
- First product: Tesla’s AI5 chip, small-batch 2026, quantity manufacturing 2027

The Terafabquestions Musk has not answered
The Terafab plan drew vital skepticism from business analysts. Musk has no background in semiconductor manufacturing, a area that’s notoriously complicated and capital-intensive. No timeline was given for when the full-scale facility could be operational.
Analysts at Bernstein estimated that producing 1 terawatt of AI silicon per 12 months would require processing the equal of greater than 22 million GPU wafers yearly, implying a complete capital requirement of $4 trillion to $5 trillion, in response to Tom’s {Hardware}.
A single, trendy modern 2nm fab prices roughly $25 billion to $35 billion to construct, and takes roughly 38 months to assemble within the U.S., in response to Electrek. For context, TSMC has spent many years and tons of of billions of {dollars} constructing its 2nm functionality.
Tesla’s CFO acknowledged the complete Terafab price will not be but included into Tesla’s 2026 capital expenditure plan, which already exceeds $20 billion, Electrek mentioned.
The announcement additionally comes as Tesla’s auto enterprise faces stress. The corporate’s gross sales declined for the second consecutive 12 months in 2025, with declines in each Europe and China, Electrek added.
Musk has a historical past of bold bulletins with timelines that show overly bold. Whether or not Terafab follows that sample or represents a real turning level in how AI firms take into consideration chip provide is one thing the business shall be watching carefully for years to return.
