$119B Elon Musk's Terafab Amazing Inside New Update!
9.4/10TL;DR
Elon Musk’s proposed Texas chip complex, known as Terrafab, could cost up to $119 billion and is being positioned as a vertically integrated semiconductor hub to supply AI chips for Tesla, SpaceX, robots, autonomous vehicles, and space systems, while Tesla is also scaling the Semi with lower operating-cost claims and a new Nevada factory.
KEY POINTS
A chip project on an unprecedented scale
Terrafab is being discussed as a semiconductor complex that could eventually exceed 100 million square feet in Grimes County, Texas, with a potential total investment of $119 billion. The announced first phase totals more than $16.8 billion and at least 3,000 jobs. At full scale, the site would be roughly 10 times the size of Gigafactory Texas, making it one of the most ambitious manufacturing proposals linked to Tesla and SpaceX.
Why Musk wants a giant fab
The project reflects expected chip demand far beyond cars. Tesla has outlined ambitions for millions of Optimus humanoid robots, potentially rising to tens of millions annually, while also pursuing a global robotaxi fleet. SpaceX is simultaneously expanding Starlink and orbital computing needs, raising the risk that outside chip supply from companies such as TSMC and Samsung could become a bottleneck.
What Terrafab is supposed to make
The site is planned as a vertically integrated semiconductor manufacturing facility, bringing logic, memory, advanced packaging and testing together. Three chip families have been identified for the initial phase: AI5, AI6 and D3. AI5 is aimed at Full Self-Driving and Optimus Gen 3, AI6 would support later robot generations, and D3 is described as a chip for space applications, where hardware must withstand radiation and extreme temperatures.
Manufacturing challenge and Intel’s role
Semiconductor fabrication is one of the hardest industrial processes to scale because small yield losses can destroy economics across millions of chips. Intel joined the project in April, and Gary Jang, a former Intel fab manager with nearly 18 years at the company, became project director. Reports indicate Terrafab could use Intel’s 14A process, giving the venture access to manufacturing know-how, process integration and advanced packaging experience that cannot be assembled quickly.
TSMC discussions shake the market
In October, Musk confirmed that Tesla and SpaceX were in discussions with TSMC about a possible role in Terrafab. No deal, timeline or ownership structure has been confirmed, but speculation alone pushed Intel shares down about 2.6% in one session while TSMC shares hit a record high. One scenario under discussion is that TSMC could operate the fab while Musk’s companies provide capital support or long-term purchase commitments.
Power, water and self-sufficiency
Terrafab is also designed around dedicated infrastructure rather than reliance on the local grid. Plans call for on-site generation centered on natural gas turbines plus large battery storage, with capacity described in the gigawatt range. Some project configurations point to more than 40 turbines of about 50 megawatts each, implying a theoretical total near 2 gigawatts, alongside industrial water sourced from Gibbons Creek Reservoir and on-site wastewater treatment.
Tesla Semi moves toward volume production
Separately, Tesla has built a 1.8 million-square-foot Semi factory in Nevada designed for up to 50,000 trucks a year, or roughly 1,000 per week at peak output. The company says it stamps steel, builds 4680 battery cells, drive axles, cooling modules and seats on site, extending the same vertically integrated model seen elsewhere in Tesla’s manufacturing strategy.
Performance, charging and economics
Tesla says the Semi can travel up to 500 miles at 82,000 pounds gross weight and nearly 600 miles at 60,000 pounds. Charging can restore about 60% of range in 30 minutes, with charging power shown around 1.2 megawatts. Based on cited operating figures, energy use of about 1.7 kilowatt-hours per mile at $0.12 per kilowatt-hour implies roughly $0.20 per mile, versus about $0.67 per mile for diesel at $5.35 per gallon, a gap that could translate to around $47,000 in annual fuel savings for a truck driving 100,000 miles.
Expansion beyond the United States
Deliveries are beginning to customers including PepsiCo, DHL, US Foods and Einride, while the Zetscale Alliance has ordered 2,500 trucks. Tesla also plans a European Semi variant with 550 kilometers of range at 40 tons, road tests in 2027, and first commercial European deliveries targeted for the end of 2027. Before the end of 2026, Tesla aims to open more than 30 Mega Charger stations with over 200 charging stalls.
CONCLUSION
Terrafab and the Semi expansion show Musk pushing deeper into industrial self-sufficiency, from chips to heavy trucks. The opportunity is vast, but so are the technical, financial and infrastructure risks that could determine whether these plans become a durable manufacturing advantage.
