Elon Musk’s chip factory, known as Terafab, is taking shape as one of the largest industrial projects ever announced. SpaceX and Tesla plan an initial investment exceeding $16.8 billion in Grimes County, Texas, according to customreceipt.com.
Sources and original reporting: SpaceX, Office of Texas Governor Greg Abbott and Reuters. Texas officials confirmed 3,000 planned jobs and more than $16.8 billion for the first phase.
Why Elon Musk is building Terafab in Texas
The semiconductor plant is designed to supply advanced chips for Tesla, SpaceX and their growing AI operations. Demand will come from autonomous vehicles, Optimus humanoid robots and computing infrastructure.
The project targets several functions under one roof:
- semiconductor manufacturing;
- logic and memory production;
- advanced chip packaging;
- semiconductor testing.
Tesla job listings describe Terafab as a vertically integrated semiconductor factory covering these processes within one operation.
That strategy could give Musk’s companies greater control over chip supply and production schedules. It also reduces dependence on separate suppliers for critical manufacturing stages.
How big will Elon Musk’s chip factory be?
SpaceX says Terafab will provide more than 100 million square feet of manufacturing space. Musk has described it as potentially the largest building on Earth.
The main announced figures show the unprecedented scale:
| Project detail | Announced figure |
|---|---|
| Initial investment | More than $16.8 billion |
| Manufacturing space | More than 100 million sq ft |
| New jobs | 3,000 |
| Location | Grimes County, Texas |
| Main users | Tesla and SpaceX |
These figures concern the project’s first announced phase. Future expansion could push total investment substantially higher than the current commitment.
What Terafab chips will be used for
Tesla needs increasingly powerful processors for autonomous driving systems and its Optimus robot program. SpaceX is also pursuing computing infrastructure connected with its broader space ambitions.
AI computing demand is therefore central to the Terafab project. The companies expect their future requirements to surpass one terawatt of compute.
Water for the complex is expected to come from Gibbons Creek Reservoir rather than local groundwater. The project is also receiving a $30 million Texas Enterprise Fund grant.
What happens next with the Terafab project?
The $16.8 billion commitment represents only the first construction phase. Development will now determine how quickly Musk can turn the enormous design into operating semiconductor capacity.
For Texas, the project brings thousands of jobs and another major technology investment. For Musk, Terafab represents something more ambitious: control over the chips powering his companies’ next generation of machines.
