Elon Musk has announced plans for a massive semiconductor manufacturing project in Austin, Texas, aimed at boosting chip production for his companies, including Tesla and SpaceX. The initiative, dubbed Terafab, could be valued at nearly $25 billion and span an enormous 100 million square feet.

The proposed development will include two fabrication plants designed to produce advanced chips for both terrestrial and space applications. These chips are expected to power everything from autonomous vehicles and humanoid robots to next-generation space technologies.
During a livestream presentation, Musk emphasized the growing gap between global chip production and the needs of emerging technologies. He pointed out that current output levels fall far short of what is required to support advancements in artificial intelligence and robotics.
“We’re very grateful to our existing supply chain — to Samsung, [Taiwan Semiconductor Manufacturing Co.], Micron and others — and we would like them to expand as quickly as they can, and we will buy all of their chips,” Musk said. “But there’s a maximum rate at which they’re comfortable expanding, and that rate is much less than we would like.”
“We need the chips, so we’re going to build the Terafab,” he added.
The Terafab complex is expected to integrate all stages of chip production under one roof, including lithography mask creation, chip fabrication, testing, and packaging. This vertically integrated approach is intended to accelerate innovation and improve design efficiency.
Roughly 20% of the facility’s production capacity will be dedicated to terrestrial uses, such as powering Tesla’s Full Self-Driving systems and Optimus robots. The remaining 80% will support space-related applications, including ambitious plans for orbital data centers.
Musk also highlighted the potential benefits of shifting computing infrastructure into space, citing reduced environmental concerns and scalability advantages.
“As soon as the cost to orbit drops to a low number, it immediately makes extremely compelling sense to put AI in space,” Musk said during his presentation. “Nobody wants the thing in their backyard.”
The Terafab project comes at a time when U.S. semiconductor manufacturing is expanding, with companies like Taiwan Semiconductor Manufacturing Co. and Intel ramping up domestic production. However, Musk’s initiative stands out for its scale and integration across multiple industries, including automotive, aerospace, and artificial intelligence.
The Terafab project reflects a broader trend of vertical integration among tech giants seeking greater control over supply chains. By producing chips in-house, Musk’s companies aim to reduce dependency on external suppliers and mitigate risks associated with global shortages.
Austin, already a growing tech hub, is likely to see significant economic benefits from the project, including job creation, infrastructure investment, and increased demand for skilled labor in semiconductor manufacturing and construction.
The development could also reshape the competitive landscape of the chip industry, positioning Musk’s ventures as major players in both terrestrial and space-based computing markets.
If realized at full scale, Terafab would not only address immediate chip shortages but also lay the groundwork for future innovations in AI, robotics, and space technology.
