Elon Musk’s Terafab construction plan puts a $16.8 billion chip factory at the center of Grimes County, Texas, where SpaceX and Tesla are building it right now. Terafab spans about 100 million square feet, which makes it more than five times larger than the world’s current largest building, and it also combines logic, memory, and advanced packaging all under one roof. The SpaceX chip factory should create 3,000 jobs in its first phase alone, and that number could grow as later phases get underway.

Elon Musk’s Terafab Construction Plan Drives SpaceX Chip Ambitions


A Building Larger Than Any On Earth
Elon Musk’s Terafab construction plan calls for a site that beats anything else on the planet in size, at least at the time of writing. Right now the New Century Global Center in Chengdu holds the record, at around 18.9 million square feet, but Terafab Texas should beat that record once it opens. Nobody has really attempted a jump in scale like this before, and that also explains why the announcement drew so much attention.
Musk said:
Terafab Texas will be the largest and most valuable building on Earth by far. And it will be stunningly beautiful.
That kind of talk is fairly typical for Musk, but the numbers behind the Elon Musk Terafab construction plan back it up, at least on paper.

Vertical Integration Behind The Terafab Construction Plan
The Terafab construction effort relies on vertical integration, so fabrication, packaging, and testing all happen inside one site instead of spreading production across separate plants. This also sets the Elon Musk Terafab construction plan apart from a fairly typical chip fab announcement.
Musk said:
We’re now embarking on the most epic chip-building effort, combining logic, memory, and advanced packaging all under one roof, in Grimes County, Texas. The Terafab is bringing cutting-edge manufacturing to America, creating thousands of high-paying jobs in the Lone Star State, and enabling us to produce AI chips at scale for use on Earth and in space.
State Money And Political Backing For Terafab Texas
Public funding ties closely into the Elon Musk Terafab construction plan and into the SpaceX chip factory itself. The company filed eight tax incentive applications with local school districts, seeking to freeze maintenance and operations taxes near 48 percent of appraised value for a decade per phase, and it also wants the state to cover the difference through the Texas JETI program.
The filing stated:
Absent the limitation, the project IRR would fall below the minimum investment threshold, and competing jurisdictions (e.g., Arizona) would present a more favorable after-tax return, in which case the project would likely be relocated outside Texas.
Governor Greg Abbott said:
The first phase of the Terafab project represents a capital investment of more than $16.8 billion and will create 3,000 new jobs.
Abbott also said:
Texas is where big ideas grow even bigger.
SpaceX and the governor’s office have not answered requests for further comment, and at the time of writing nobody has set a confirmed date for when construction will actually break ground. The SpaceX chip factory, also known simply as Terafab Texas, still counts as one of the largest single building projects announced anywhere in the world this year, and it is one that Musk clearly wants people to keep watching.
