Elon Musk’s aerospace and automotive companies plan to invest at least $55 billion in a new semiconductor fabrication plant in Texas, officials said Wednesday. The project, called “Terafab,” will be a joint venture between SpaceX and Tesla and is slated to produce chips for artificial‑intelligence (AI) applications, robotics and data‑center operations in space.
The Texas facility will be located in Grimes County, roughly 70 miles (110 km) northwest of Houston. A public‑hearing notice filed with the Grimes County commissioners court states that the initial capital outlay is $55 billion, with potential expansion raising total investment to $119 billion. The commissioners are scheduled to meet on 3 June to consider a property‑tax abatement for the development.
According to the notice, Terafab “would represent a transformative investment in domestic semiconductor manufacturing capacity.” While Musk has no prior experience in chip production, he argues that the combined demand from Tesla’s electric‑vehicle fleet and SpaceX’s launch and satellite operations will soon outstrip the supply capabilities of existing global chip manufacturers.
The plant’s long‑term objective is to manufacture semiconductors capable of supporting 100 to 200 gigawatts of computing power on Earth and a terawatt of processing capacity in space. If realized, the facility would significantly bolster U.S. semiconductor independence and could reduce reliance on overseas supply chains that have faced disruptions in recent years.
The announcement follows broader industry trends, as governments and private firms intensify efforts to secure domestic chip production amid growing AI workloads and geopolitical tensions. The United States has recently enacted subsidies and tax incentives to encourage advanced‑technology manufacturing on American soil, and Musk’s proposal aligns with those policy objectives.
Stakeholders will now await the outcome of the Grimes County tax‑abatement hearing. Approval could accelerate construction timelines, which have not yet been disclosed. The project’s scale and ambition make it one of the largest private investments in U.S. semiconductor infrastructure to date, underscoring the strategic importance of next‑generation computing hardware for both terrestrial and space‑based applications.
