Terafab is a planned semiconductor fabrication plant jointly developed by Tesla, SpaceX, and Intel.[1][2] The venture was announced by Elon Musk on March 21, 2026, and centers on the construction of a vertically integrated large-scale facility designed to produce more than one terawatt (one trillion watts) of artificial intelligence (AI) compute capacity per year. It aims to produce integrated circuits, memory modules and multi-chip modules under one roof by consolidating every stage of the semiconductor device production process, including chip design, fabrication, memory production, advanced packaging, and testing.

Initial prototype fab operations are to be focused in Austin, Texas, in proximity to Tesla's existing Gigafactory Texas, with a permanent plant planned for Grimes County, Texas on the site of a former electric generating plant. County filings in May 2026 discussed an initial outlay of about US$55 billion and as much as $119 billion across all phases of the Grimes County facility.[3] In August 2026 Tesla and SpaceX said they would invest about $16.8 billion in a first phase at that site.[4]

Background and development

[edit]
AI chips for Tesla Autopilot are among the products planned for manufacture at Terafab.

The project was teased by Musk in early 2026 and officially announced on March 21, 2026, during a special event at the defunct Seaholm Power Plant in Austin, Texas.[5] Musk described Terafab as a pivotal step toward humanity becoming a galactic civilization, with the announcement accompanied by a live SpaceX broadcast on X and conceptual imagery of a prototype 100 kW "AI Sat Mini".[2]

Musk said that the global chip industry cannot expand quickly enough to meet the demand that Tesla will have for "edge inference compute" for Tesla vehicle and Optimus humanoid robot production, nor for the special semiconductor characteristics required for orbital AI infrastructure. Musk said all the current fabrication facilities on Earth produce only about 2% of what Tesla and SpaceX will need across all projects:[5] "We either build the Terafab, or we don't have the chips, and we need the chips, so we build the Terafab."[6] The project integrates efforts under the SpaceX/xAI umbrella with Tesla's existing silicon development.

In April 2026, Intel announced it would join the Terafab project to contribute manufacturing expertise.[7] As of 2026, Intel is one of three manufacturers worldwide who are producing sub-5 nanometer (nm) chips at scale, the other two being Taiwan Semiconductor Manufacturing Company (TSMC) and Samsung Electronics. In April 2026, Musk announced Intel's 14A (1.4 nm) manufacturing process would be used at the full-scale Terafab, saying that by the time Terafab scales up, the process "will be probably fairly mature or ready for prime time".[8] He also announced a division of labour, with Tesla focusing on the prototype fabrication and SpaceX in the lead on the initial part of the full-scale Terafab.[8]

In June, SpaceX presented a more detailed first-generation satellite design called AI1.[9]

In early September 2026, Texas government filings listed a planned construction start of December 1, 2026, and completion by the end of 2028 for the Grimes County facility.[10] SpaceX said the site would be powered by on-site natural-gas generation and large battery arrays rather than Tesla solar equipment.[11] SpaceX's May 2026 initial public offering registration stated that Terafab was in a very early stage and that Tesla and SpaceX had agreed to only a general framework, with financial terms, intellectual property rights, and Intel's and Tesla's continuing participation still subject to later agreements.[12]

Prototype fabrication facility

[edit]

Tesla is building a prototype "Advanced Technology Fabrication" facility at the existing Tesla GigaTexas site that will be capable of producing each of the parts of chip manufacturing in one facility in order to iterate rapidly—"make a chip, test it, revise the mask, and repeat without shipping wafers between sites"—a capability that does not currently exist in any other chip fabrication site globally. The aim is to manufacture chips for both AI edge inference and for AI model training with chips optimized for operation in space.[6]

In April 2026, Tesla broke ground on the prototype fab.

The project targets 2-nanometer process technology and an initial output of 100,000 wafer starts per month,[5] though this was later revised by Musk to "maybe a few thousand wafers per month, but it's really intended to try out ideas".[8] Tesla's fifth-generation AI chip, AI5, is among the first products the pilot facility will be designed to produce, with small-batch production anticipated in 2026 and volume production in 2027.[13]

Grimes County facility

[edit]

In June 2026, Grimes County commissioners approved a full property tax abatement package to bring Terafab to the former site of the Gibbons Creek Steam Electric Station,[7][14] adjacent to the Gibbons Creek Reservoir. Grimes County is located southeast of the Bryan-College Station metropolitan area, home of Texas A&M University; the Texas A&M University System is building a semiconductor institute at the RELLIS campus which is planned for completion in 2028.[15]

Once fully operational, the facility is expected to cover up to 100,000,000 square feet (9,300,000 square metres), which would make it one of the largest factories in the world. SpaceX has stated that at least 1,800 permanent jobs will be created.[16] Some county residents have expressed concern about the scale of the project, its potential impact on the rural population, and its environmental consequences.[17]

Musk said that the long-term goal is to have 1 million wafer starts per month and produce between 100 and 200 billion custom AI and memory chips per year at the full-scale facility.[5]

In August 2026, SpaceX and Tesla announced that Terafab would be built at the Grimes County facility. The companies announced an initial investment of approximately $16.8 billion. SpaceX and Tesla said the chips would support applications including Tesla's Optimus humanoid robots and Cybercab vehicles and SpaceX's planned space-based data centers.[4][18]
