Tesla chief executive Elon Musk unveils plan for vast Terafab chip facility
Elon Musk unveils Terafab, a US$20 billion plan to build what he claims will be the world’s largest chip manufacturing facility.
Elon Musk has revealed plans for a new semiconductor venture called Terafab, which he describes as the largest chip manufacturing facility ever proposed. The project is a joint effort involving Tesla, SpaceX and xAI. It is intended to address what Musk sees as a critical shortage of computing capacity for his companies’ future ambitions.

The announcement was made during a livestream on X, where Musk outlined an expansive vision for scaling chip production. He framed the initiative as essential to advancing technologies ranging from artificial intelligence to space infrastructure, while also linking it to broader ambitions of building what he described as a “galactic civilisation”.
A response to growing demand for computing power
Musk said the Terafab project is driven by rapidly increasing demand for advanced chips across his companies. Tesla’s work on autonomous driving systems and humanoid robots, alongside SpaceX’s space-based operations, requires significant computing resources that current suppliers may struggle to meet.
He acknowledged existing partnerships with major semiconductor manufacturers, including Samsung, TSMC and Micron, noting their importance in supporting current operations. However, Musk claimed that their combined capacity would only meet a small fraction of the company’s future requirements.
“We either build the Terafab, or we don’t have the chips,” Musk said during the livestream. “And we need the chips, so we’re going to build the Terafab.”
The proposed facility aims to produce up to a terawatt of computing power annually, a scale that far exceeds typical chip manufacturing output. Musk suggested that achieving this level of production is necessary to sustain advancements in artificial intelligence and other high-performance computing applications.
Project scope, location and investment
The Terafab initiative is expected to require at least US$20 billion in investment, making it one of the most expensive semiconductor projects ever proposed. The first phase will begin with the construction of an Advanced Technology Fab in Austin, Texas, where Tesla already maintains its headquarters.
Musk outlined plans for the facility to produce two main categories of chips. The first will support terrestrial applications, including Tesla’s Full Self-Driving technology and its Optimus humanoid robot programme. The second will focus on more robust and high-performance chips designed for use in space environments.
These space-grade chips are expected to play a role in SpaceX’s longer-term ambitions. Earlier this year, the company filed an application with the US Federal Communications Commission to deploy up to one million satellites, forming what Musk described as an “orbital data centre”. The Terafab facility could provide the processing hardware needed to support such a network.
The scale and scope of the project reflect Musk’s broader strategy of vertical integration, reducing reliance on external suppliers while gaining greater control over critical technologies.
Ambition tempered by past challenges
While the Terafab project represents a bold step, it also comes against the backdrop of Musk’s history of ambitious announcements that have not always materialised as initially described. Previous initiatives, such as the Hyperloop transport concept and earlier promises around fully autonomous driving, have faced delays or remain incomplete.
Tesla’s Cybertruck, once promoted at a significantly lower price point, has also seen its market positioning change since its initial unveiling. These examples have led some industry observers to approach new announcements with caution.
Despite this, Musk continues to position Terafab as a necessary and transformative project. By addressing what he perceives as a looming shortage of advanced chips, he argues that the facility will enable continued innovation across multiple sectors, from automotive technology to space exploration.
The semiconductor industry is already under pressure globally, with demand for advanced chips outpacing supply in recent years. If realised, Terafab could become a major new player in this space, though its success will depend on execution, funding, and the ability to scale production to unprecedented levels.
For now, the project remains in its early stages, with timelines and partnerships yet to be confirmed.
