Terafab is being developed by SpaceX, Tesla, and xAI, placing it at the centre of Musk’s push to connect artificial intelligence, computing power, and space infrastructure.
Elon Musk’s plan to build a major chipmaking facility in Texas, in the United States, has taken a clearer shape after SpaceX filed plans for a $55 billion (€46.8 billion) chipmaking facility on Wednesday.

Musk announced the Terafab project in March to produce more than one terawatt of artificial intelligence (AI) compute capacity per year.
At the launch, Musk framed the project as a response to future chip shortages, according to reports at the time.
He said he was grateful to existing chip suppliers such as Samsung and TSMC, but said demand from his companies would eventually exceed total global chip output.
What is Terafab?
The project, known as Terafab, would be built in Grimes County, in the US, and would focus on semiconductor manufacturing and advanced computing, two areas that are increasingly central to Musk’s artificial intelligence and space ambitions.
Local documents describe it as a multi-phase facility for semiconductor manufacturing and advanced computing.
Terafab would give Musk more control over the chips and computing power needed across SpaceX, Tesla, and xAI.
Tesla has made autonomous driving and robotics central to its strategy, SpaceX operates Starlink and other satellite systems, and xAI is developing large AI models that require significant computing capacity.
Why is he building this now?
The project comes as advanced chips have become one of the most important resources in the global technology race.
AI systems need specialised semiconductors to train models, process data, and run complex software.
Demand for those chips has surged as companies build larger AI systems, while governments in the US and Europe are trying to grow their own semiconductor industries and reduce reliance on supply chains concentrated in East Asia.
Terafab would bring those ambitions closer together by linking chipmaking, computing power, artificial intelligence, and space infrastructure.
The project is still at an early stage. Local officials in Texas are expected to discuss proposed incentives for the site at a public hearing in early June, and the facility remains subject to approvals, financing, and construction hurdles.
