Report Says Tesla and SpaceX Plan a $55 Billion Texas Chip Factory Tied to Robotics, Taxi Plans, and Space-Based AI

Tesla and SpaceX are reportedly planning a large semiconductor factory in Texas that could cost about $55 billion, as part of a broader push to build compute capacity for robotics, autonomous vehicles, and AI operations in space. The plan is described in a report carried by Yahoo Finance that points to a concept known as “Terafab.”

Semiconductors are the specialized computer chips that power everything from vehicle controllers to data centers and AI accelerators. For carmakers moving toward software-defined vehicles and on-board autonomy, chip supply and the ability to tailor compute to specific workloads can become as important as manufacturing scale in vehicles themselves.

According to the report, the Terafab concept is positioned to support Tesla’s efforts tied to Optimus, a humanoid robot program Tesla has discussed in public for several years, as well as Cybercab initiatives, which the company has described as part of its longer-term strategy for an autonomous, ride-hailing style vehicle. The report also links the chip factory concept to “orbital AI,” an idea associated with processing or running AI-related functions using systems deployed in space.

The reported figure of $55 billion reflects an ambition to build at a scale described as “factory” rather than a standard production facility. However, the report itself frames the effort as contingent on a broader, higher-level vision estimated at $119 billion, implying that the chip project would be one element of a larger capital plan rather than a fully defined near-term buildout.

What remains unclear from the reporting is whether either company has filed permits, entered binding supply agreements, or made a formal investment decision publicly. The concept also raises questions about the chip types involved, whether the plan would include leading-edge fabrication, and how the resulting components would be allocated between vehicle, robotics, and space-related deployments.

From a sector perspective, the automotive and aerospace ecosystems are increasingly converging around the supply of advanced chips. Tesla’s business depends on specialized compute for driver-assistance and vehicle software, while robotics programs require real-time sensing and control. Space-based AI ambitions, if pursued operationally, would also demand substantial compute capacity and reliability.

The companies have not, in the material referenced by the Yahoo Finance-linked report, provided additional specifics about the Terafab timeline, location particulars inside Texas, expected production start dates, or how costs and responsibilities would be divided between Tesla and SpaceX. Without those details, it is not possible to determine how much of the concept is already funded and engineered versus what is still in planning discussions.
