Elon Musk’s SpaceX has submitted documentation for the establishment of its ambitious Terafab chip fabrication facility, outlining an initial investment of $55 billion. As reported by Reuters, the plans filed with Grimes County, Texas, suggest that the overall expenditure could reach as high as $119 billion if all development phases are completed. This initiative represents a collaborative effort between SpaceX and Musk’s other enterprise, Tesla.
According to a notice on Grimes County’s website, the facility will be a multi-phase, vertically integrated semiconductor manufacturing and advanced computing site. It aims to significantly enhance domestic semiconductor production capacity, and a commissioners’ meeting has been called for June 3 to discuss a property tax abatement for the project.
The Terafab project is strategically critical for Musk, as it is expected to advance the artificial intelligence (AI) aspirations of Tesla, SpaceX, xAI, and other associated ventures. By consolidating every part of the semiconductor production process—including design, fabrication, memory production, and packaging—under one roof, Terafab seeks to streamline operations to meet the growing demands of AI and robotics.
Musk has described Terafab as “the most epic chip-building exercise in history,” citing frustrations with traditional chip manufacturers such as TSMC and Samsung, who are currently unable to meet the rapid chip demand of his companies. He voiced that building the Terafab is essential to secure the necessary chips for their projects, suggesting that the existing manufacturing capacity falls significantly short of their requirements.
He emphasised that the current AI compute output is around 20 gigawatts per year, while global production is only about 2% of what his companies actually need, highlighting a severe supply shortage.
The facility will focus on two primary chip types: an edge-inference processor intended for Tesla’s Full Self-Driving systems, Optimus humanoid robots, and Robotaxi fleets, alongside a high-power variant designed for space, which will support SpaceX satellites, orbital data centres, and xAI projects.
In a notable shift from his typical ‘do-it-all’ philosophy, Musk indicated last month during Tesla’s first-quarter earnings call that Terafab will employ Intel’s 14A process for manufacturing chips, reflecting a willingness to incorporate external expertise in the undertaking.
The timing of the Terafab announcement is particularly intriguing, especially as there is speculation that SpaceX might consider going public as early as this summer. However, according to Morgan Stanley, the production of chips at Terafab may not commence until around mid-2028, even with an aggressive build-out strategy.
Terafab promises to be a transformative player in the semiconductor landscape, potentially positioning Musk’s ventures at the forefront of AI and robotics innovation, but there remain significant hurdles to overcome before the facility can begin operations.
