Samsung Electronics plans to produce the STM32V8 microcontroller used on SpaceX’s Starlink satellites at its plant in Austin, Texas, the Seoul Economic Daily reported on 15 November, citing the semiconductor industry and the US Commerce Department. The paper said Samsung is investing $1.9 billion, about 2.7 trillion won, to expand the Austin facility.
That $1.9 billion is at most 5.1% of the over $37 billion Samsung is expected to invest in Central Texas, and 40% of its up to $4.745 billion CHIPS Act award, by our arithmetic from the Commerce Department’s NIST project page. Samsung told the paper it is difficult to officially confirm contracts with individual customers.
Business Pill · Lead Time
A short explainer on lead time: why the wait for capacity is part of its price. It teaches the general idea and does not discuss Samsung, ST, SpaceX or the Austin plant.
The key insight: As we read it, the reported Austin plan would add a US site for a chip ST already makes with Samsung Foundry, at a fab the CHIPS award earmarks for FD-SOI. The $1.9 billion the Seoul Economic Daily reported is at most 5.1% of Samsung’s $37 billion-plus Texas plan, by our arithmetic.
The paper described the STM32V8 as a high-performance microcontroller built on an 18-nanometre fully depleted silicon-on-insulator (FD-SOI) process that Samsung and France’s STMicroelectronics developed together, designed to hold its performance in harsh environments such as space.
It reported that Samsung plans to make at Austin the STM32V8 volume currently produced in France, and gave a target operation date of 2030. The paper said the Austin plant runs mature processes from 65 nanometres to 14 nanometres, a range that includes the chip’s 18-nanometre process.
An industry official told the paper, in our translation from Korean, that “the likelihood has grown that the Starlink chips will also be produced at the Austin fab at the customer’s request”. The official also said Samsung’s Korean foundry lines have reached full capacity, which is speeding up its US expansion.

Samsung plans to work with STMicroelectronics to mass-produce satellite chips for SpaceX in Austin, Texas, according to Korean media reports.
Samsung reportedly plans to invest $1.9 billion to expand its Austin fab and aims to bring the new capacity online in 2030.
The account @jukan05 posted this at 10:45 UTC on 15 November, citing Korean media reports and linking the Seoul Economic Daily article: Samsung plans to work with STMicroelectronics to mass-produce satellite chips for SpaceX in Austin, and reportedly plans a $1.9 billion expansion aimed at 2030.
What ST and SpaceX Said About the Chip
STMicroelectronics launched the STM32V8 on 18 November 2025 and said in its release: “It is manufactured in ST’s 300mm fab in Crolles, France, and also in collaboration with Samsung Foundry”. ST said SpaceX selected the chip for Starlink, using it in a mini laser system that links satellites in low Earth orbit.
Michael Nicolls, vice president of Starlink engineering at SpaceX, said in the release: “The successful deployment of the Starlink mini laser system in space, which uses ST’s STM32V8 microcontroller, marks a significant milestone in advancing high-speed connectivity across the Starlink network”.
He added: “We look forward to integrating the STM32V8 into other products and leveraging its capabilities for next-generation advanced applications”. ST said the chip runs at up to 800 MHz and that key OEMs would have it from the first quarter of 2026. Starlink is the core of how SpaceX makes money.
ST’s role in Starlink runs wider than this chip. In a joint release with SpaceX on 15 December 2025, ST said its panel-level packaging had reached “a delivery run rate of over 5 million chips per day” for Starlink, over 1.8 billion a year by our arithmetic, and that Starlink uses STM32, secure elements and GNSS parts across its satellites, ground infrastructure and terminals.
That release said Starlink products are manufactured in fabs located in France and packaged and tested in Malaysia and Malta. Gwynne Shotwell, SpaceX’s president and COO, said in it: “Our partnership with STMicroelectronics has been instrumental in enabling the scale and performance of Starlink”.
What the CHIPS Award Says About Austin
The NIST page says the Commerce Department awarded Samsung Austin Semiconductor up to $4.745 billion in direct funding, against expected capital expenditure of over $37 billion across Taylor and Austin. For Austin it lists an expansion “to support the production of leading fully depleted silicon-on-insulator (FD-SOI) process technologies for critical U.S. industries, including aerospace, defense, and automotive”.
The page adds that the Austin investment includes commitments to collaborate with the US Department of Defense, and that “All facilities are expected to be operational by 2030”. The Taylor half covers two 2nm logic fabs and an R&D fab; the first Taylor fab is eyeing December trial runs.
The Structural Read
As we read the sources, the pieces were public before this report: ST’s release says the STM32V8 is made in Crolles and with Samsung Foundry, and the NIST page says Austin’s expansion is for FD-SOI. The new element in the paper is the Austin site for the Starlink volume and the $1.9 billion figure.
As we read the NIST page, Austin is the smaller, mature-node half of a Texas build whose Taylor half covers two 2nm logic fabs and an R&D fab; the $1.9 billion equals 40% of the up to $4.745 billion award, by our arithmetic, but the page does not split the award by site.
Michael Nicolls, SpaceX, in ST’s release of 18 November 2025
“The STM32V8’s high computing performance and integration of large embedded memory and digital features were critical in meeting our demanding real-time processing requirements”
Three Implications
FOR SPACEX ST says SpaceX uses the STM32V8 in the Starlink mini laser system; the paper reports a plan to add Austin production to the volume made in France.
FOR SAMSUNG FOUNDRY The paper says Austin runs 65 to 14 nanometre processes and that Samsung’s Korean foundry lines are at full capacity, per an industry official.
FOR THE CHIPS AWARD NIST lists Austin’s FD-SOI expansion for aerospace, defense and automotive, with all facilities expected to be operational by 2030.
The framework opens: “The digital economy rests on a physical foundation that most people in that economy never see.”
As we read it, a microcontroller made on a mature-node line sits under Starlink’s laser links, and the reported plan moves part of that physical layer to Texas. The framework predates this report and does not discuss Samsung, ST or SpaceX.
What Is Not Established
Samsung did not confirm a SpaceX or STMicroelectronics contract, and the paper attributes the plan to the industry and the Commerce Department. The NIST page we read names FD-SOI for aerospace, defense and automotive but does not name SpaceX, STMicroelectronics or the STM32V8, and it does not break out an Austin dollar figure.
The $1.9 billion is the paper’s figure. The paper dated SpaceX’s statement on the chip to last December; the SpaceX quote on the STM32V8 we found is in ST’s release of 18 November 2025, and the joint ST and SpaceX release is dated 15 December 2025. We did not contact Samsung, STMicroelectronics or SpaceX for this piece.
This Week In The AI Supercycle
AI Lost Its Central Banker, the Lab Oligopoly, and the Future of Open Source
This week’s issue: the Nvidia leadership change, read as the AI build-out losing its central banker: who now finances the GPU landlords, backstops the data centres and sponsors open models, and why two labs are becoming the bank.
Samsung plans to make the Starlink microcontroller STM32V8 in Austin, backed by a $1.9 billion expansion, the Seoul Economic Daily reported. ST already says the chip is made with Samsung Foundry, and the CHIPS award earmarks Austin for FD-SOI by 2030; the $1.9 billion is at most 5.1% of the $37 billion-plus Texas plan, by our arithmetic.
A note on sourcing. The production plan, the $1.9 billion figure, the 65 to 14 nanometre range and the 2030 target are from the Seoul Economic Daily article of 15 November 2026, which we read in full in Korean; the industry official’s quote is our translation. The chip’s manufacturing sites, SpaceX’s selection and Michael Nicolls’ words are quoted from STMicroelectronics’ release of 18 November 2025.
ST’s Starlink run rate, manufacturing sites and Gwynne Shotwell’s words are from the ST and SpaceX release of 15 December 2025. The award, investment and Austin FD-SOI scope are from the NIST CHIPS for America project page. Shares are our arithmetic. We did not contact Samsung, STMicroelectronics or SpaceX; the story reached us through a post on X by @jukan05 that cited the paper.
