One would serve Tesla's AI needs for its vehicles and Optimus robots. The other would target space-based data centers under SpaceX's vision. Ives calls the Terafab the "first step" toward full operational integration between the two companies.
On March 17, 2026, Tesla announced plans to pursue semiconductor manufacturing through its "Terafab" initiative, carrying an estimated $25-40 billion price tag — potentially marking the company's first capital raise via stock offering since ...
Ives calls the Terafab the "first step" toward full operational integration between the two companies.
Wedbush analyst Dan Ives predicts a merger between Tesla and SpaceX by 2027, noting that the Terafab project is the first step toward a unified AI empire.
He lays his cards on the table: 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 transmit data from the sky back to the ground. Now Terafab fills in the last piece—chip manufacturing.
The ambitious Terafab project, initiated by Elon Musk through a collaboration between Tesla, SpaceX, and xAI, is a colossal investment with an estimated cost ranging between $20 to $25 billion.
Tesla, SpaceX, and xAI, under the helm of Elon Musk, have announced the Terafab project, a $20-25 billion mega chip fabrication facility set to be built in Austin, Texas by March 2026.
Tesla Inc. surged to the forefront ... billion semiconductor manufacturing project in Austin, Texas. Developed as a joint venture between Tesla, SpaceX, and xAI, this initiative aims to produce advanced two nanometer technology ...
Elon Musk launched Tesla's "Terafab Project" today, kicking off what the company describes as a vertically integrated semiconductor fabrication operation designed to produce Tesla's next-generation AI chips and reduce dependence on outside foundries.
Last week, Elon Musk unveiled his plans for a “Terafab”—a facility capable of producing 1 terawatt (TW) of AI chips per year when complete and ~50x larger than current global available new compute in a single site.
According to a report from Yahoo Finance, Elon Musk has introduced a new project named Terafab, focusing on semiconductor production. This initiative represents his latest major manufacturing challenge.
The first set of chips from TeraFab will focus on AI inference, chips designed to run AI models quickly and efficiently. These chips will power Tesla’s self-driving cars, robotaxi fleet and the Optimus humanoid robot. ... The chips are expected to be built on a 2nm process, one of the most ...
TrendingAI Expo Memory chips Nvidia AI Search NTN Convergence Robotics Report Advanced Packaging · Trending · SUBSCRIBE · CONNECT WITH US · Home Tech Semiconductors · Amanda Liang, Taipei Mar 30, 2026, 11:38 0 · Credit: AFP · Elon Musk recently announced the launch of the "Terafab" project, aiming to expand compute production capacity to 1 TW per year, which is about 50 times the current global compute supply of around 20 GW.
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.
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.
The Terafab chip factory announced March 21 is designed to produce custom D3 radiation-hardened processors specifically for these orbital satellites — with 80% of Terafab’s production allocated to space applications.
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".
That’s what 80% of Terafab produces. Not chips to compete with TSMC on Earth.
The logic behind it is strikingly simple: Tesla needs chips for autonomous vehicles, for the humanoid robot Optimus, and for AI inference; SpaceX requires radiation-proof space chips for a planned orbital data center infrastructure; and xAI, according to Musk himself, will claim the majority of the total capacity. Since existing suppliers like TSMC and Micron Technology can no longer fully meet the steadily growing demand, Musk sees no other way: "We either build the Terafab or we don'
💸 Critics warn that Terafab could become a trillion-dollar boondoggle if costs, logistics, and legal frameworks aren't right. 🧠 Proponents see it as a stroke of genius that pushes the boundaries of energy, scalability, and sustainability.
