Tesla and SpaceX are “holding talks with South Korean semiconductor materials, components and equipment suppliers to secure a supply chain for their Terafab chip manufacturing project”, the Korean trade outlet THE ELEC reported on 20 October. Terafab representatives visited booths run by about 10 Korean companies on the opening day of SEMICON West.
THE ELEC puts the goal at a fab “capable of processing 1 million wafers a month within 10 years”, and says industry observers expect an initial facility of 100,000 wafers a month before 2030. By our arithmetic, that first phase is 10% of the goal.
Business Pill · VERTICAL INTEGRATION
A short explainer on vertical integration, when a company makes the inputs it used to buy. It teaches the general idea only and says nothing about Terafab or its suppliers.
The key insight: THE ELEC reports Terafab is in talks with about 10 Korean suppliers for a fab aimed at 1 million wafers a month within 10 years; the 100,000-wafer initial facility industry observers expect before 2030 is 10% of that goal, by our arithmetic.
THE ELEC names ENF Technology, Dongjin Semichem, Asflow, BMT, GnG Intech, Unisem, MiCo and Hanmi Semiconductor among the companies Terafab visited on 13 October. It reports that “Several companies have already signed nondisclosure agreements (NDAs) and advanced to discussions over specific products”.
The report says KoMiCo, MiCo’s cleaning subsidiary, “signed a three-party NDA with Tesla and SpaceX about a month ago”, that Hanmi Semiconductor is discussing thermocompression bonders, and that HPSP “has agreed to supply one high-pressure hydrogen annealing (HPA) system for Terafabโs R&D line”.
Outside Korea, THE ELEC writes that Fujifilm “holds regular meetings with Terafabโs procurement team”, and that Lam Research and Applied Materials “are also understood to have established dedicated Terafab teams”.
Terafab wafer capacity as reported by THE ELEC (20 October 2026): an initial facility of 100,000 wafers a month that industry observers expect before 2030, and a goal of 1 million wafers a month within 10 years. 10% is our arithmetic.
The Fabs Musk Reportedly Tried to Buy
THE ELEC quotes an official at an overseas equipment supplier: “My understanding is that Musk initially considered acquiring manufacturing facilities from Intel, TSMC and Micron, but shifted toward partnerships after being turned down”. The report says the companies “are working with Intel on logic semiconductors and are also in discussions with TSMC”.
On price, the report quotes a Korean equipment official: “Excluding China, there arenโt many suppliers, and Japanese companies are expensive”. It adds that Tesla and SpaceX do not do business with Chinese suppliers. We covered Musk saying his companies will build and run Terafab on 11 October.
What a Follow-Up Reportedly Adds
On 31 October the X account @jukan05 posted a summary of what it called a follow-up report by THE ELEC. We could not find that follow-up article, so these points are the account’s summary: that “Terafab is reportedly working with Samsung as well as Intel and TSMC”, that “Micron reportedly declined to participate in Terafab”, and that “SK hynix will eventually end up working with Terafab as well”.
The same post says “Fabs across Texas are reportedly losing substantial numbers of employees to Terafab”, naming NXP and Samsung. We have not verified these points against THE ELEC’s text.
The Business Lever: A Supply Chain Before a Fab
THE ELEC puts Terafab’s initial investment at an estimated $16.8 billion, with more than 3,000 jobs expected, and says SpaceX “signed a tax abatement agreement with Texas earlier this month and began construction”. It says most companies in talks are existing suppliers to Tesla or SpaceX, and that former Intel personnel overseeing Terafab “have also brought Intel suppliers into the project”. We covered the Texas plant and its natural gas power in August.
The Structural Read
As we read THE ELEC’s report, supplier talks span materials, piping, cleaning, environmental equipment and bonders, several already under NDA, while construction in Texas has begun.
As we read it, the report’s account that Musk first considered buying fabs from Intel, TSMC and Micron rests on one unnamed overseas supplier official.
As we read @jukan05’s summary of a follow-up we could not find, Samsung is reportedly working with Terafab and Micron reportedly declined; we have not checked those points against THE ELEC’s text.

“Iโve never seen this level of execution speed elsewhere in the semiconductor industry.”
Three Implications
FOR KOREAN SUPPLIERS THE ELEC reports that several have signed NDAs and that HPSP has agreed to supply one annealing system for Terafab’s R&D line.
FOR INTEL AND TSMC THE ELEC reports Terafab is working with Intel on logic chips and is in discussions with TSMC; it does not give terms.
FOR SPACEX THE ELEC reports SpaceX signed a tax abatement agreement with Texas and began construction; it does not disclose a separate Terafab entity.
The framework says “The job of any operator, investor, or builder is to know which layer they are operating inside and which layer the binding constraint is rotating toward next.”
As we read it, Terafab is an attempt to own the chip-making layer that Tesla and SpaceX otherwise buy from others. The framework predates THE ELEC’s report and does not discuss Terafab.
What Is Not Established
THE ELEC does not give contract values, and Tesla and SpaceX, it says, “have not disclosed a separate corporate entity or ownership structure”. The account of fabs being turned down comes from one unnamed official. The Samsung, SK hynix and Micron points come from @jukan05’s summary, not from an article we read.
This Week In The AI Supercycle
Execution Fault Lines, Concentrated Demand, and Geopolitical Firewalls
This week’s issue: the AI build is not short of demand for its parts. It is short of cheap money, and its end revenue rests on a narrow base of large, often venture-funded buyers.
THE ELEC reports Terafab is in talks with about 10 Korean suppliers, several under NDA, for a fab aimed at 1 million wafers a month within 10 years. The initial 100,000-wafer facility industry observers expect before 2030 is 10% of that goal, by our arithmetic.
A note on sourcing. The supplier talks and figures are reported by THE ELEC, a Korean trade outlet, citing company and industry officials. The Samsung, SK hynix and Micron points come from a summary posted on X of a follow-up report we could not find. We did not contact Tesla, SpaceX or the suppliers named. Figures labelled our arithmetic are our own.
