The $119 Billion GigaFactory | Inside Elon Musk's New Terafab Revealed
9.4/10TL;DR
Tesla and SpaceX are pursuing Terrafab, a vast Texas semiconductor complex aimed at securing advanced chip supply for AI, robotics, vehicles and space computing, while Tesla is separately accelerating production and deployment of its steering wheel-free Cybercab.
KEY POINTS
Terrafab’s scale
Terrafab is planned as a semiconductor complex in Texas that could eventually reach 100 million square feet, roughly ten times the floor space of Gigafactory Texas and about 50 times the size of the Pentagon. Long-term plans discussed around the site point to output of as much as 1 million wafers per month, making it one of the most ambitious chip-manufacturing projects ever proposed in the United States.
Investment and location
The most expansive scenario discussed for the project reaches $119 billion, though that is not the amount already committed. An initial phase tied to Grimes County and land near the former Gibbons Creek Power Plant was announced at more than $16.8 billion, with at least 3,000 jobs expected.
Strategic reason for the project
The project is meant to reduce dependence on outside chip suppliers and close what Elon Musk has described as a severe supply gap for future products. The planned output would support processors and memory for Optimus humanoid robots, self-driving vehicle systems, and computing workloads linked to SpaceX, with internal demand framed as far beyond current available supply.
Aggressive timeline
The first experimental chips are targeted for May or June 2027, with mass production aimed for late 2028. That schedule is unusually aggressive for an advanced fab, where construction, equipment installation, process tuning and yield improvement typically take years.
Two-phase launch plan
Rather than waiting for the full Grimes County facility, the effort is split into two stages. Research, process development and prototype output would begin at a semiconductor lab on the grounds of Gigafactory Texas in Austin, while large-scale manufacturing would later move to the dedicated Terrafab site.
First chips and product roadmap
The first planned chip is an experimental SRAM device, intended to validate process stability and transistor fabrication before larger commitments are made. Longer term, the fab is expected to focus on three chip families: AI5 and AI6 for vehicle and robot AI workloads, and D3 for space-oriented computing.
Partners and technology questions
Intel and TSMC have both surfaced in discussions around the project. Intel brings manufacturing and packaging experience, and its 14A process has been mentioned as a possible technology option, while TSMC has been discussed as a potential partner rather than the owner or operator of the site. Tesla has also reportedly recruited veteran fab talent from Intel.
Equipment and utility demands
The complex would require leading-edge tools such as ASML extreme ultraviolet lithography systems, each costing hundreds of millions of dollars and requiring highly controlled installation. Power demand could be extraordinary, with plans discussing more than 40 natural-gas turbines at roughly 50 megawatts each, or close to 2 gigawatts in total, alongside battery storage to prevent even brief voltage drops from ruining wafers. Large industrial water use and on-site wastewater treatment are also part of the concept.
Big promises, major risks
Claims around 1 million wafers per month, more than 1 terawatt of annual computing capacity, and economic output comparable to a top-20 national economy remain aspirational rather than proven. The project still faces familiar semiconductor risks: delays, poor yields, supplier bottlenecks, talent shortages and the challenge of integrating logic, memory, packaging and testing in one giant facility.
Cybercab production surge
Separately, Tesla is ramping its two-seat autonomous Cybercab in Texas. The line reportedly uses about 25 automated stations, far fewer than conventional vehicle lines, with overall automation near 78% and full automation in body assembly. Installed capacity is said to exceed 125,000 vehicles per year, while modular assembly and color-integrated exterior panels reduce factory space and eliminate a traditional paint shop.
Fleet growth and economics
In Texas, registered Cybercabs have reportedly climbed to 544, above 57 Model Y robotaxis, for a total robotaxi fleet of about 1,151 vehicles. Tesla has said it wants to expand from Austin to Dallas in November 2026, with sightings in Houston and Miami fueling expectations of wider rollout. The vehicle is reported to target a price below $30,000, a service life of 500,000 miles, and operating economics of roughly 20 cents per mile, though those figures still need real-world validation.
CONCLUSION
Terrafab and Cybercab reflect a broader push by Tesla to control both the compute supply chain and the deployment platform for autonomous systems. The scale is extraordinary, but the central question is whether execution can match the ambition on manufacturing, cost and safety.
