Tesla opens 'Terafab' tomorrow
Tesla’s 'Terafab' AI‑chip fab is slated to launch tomorrow in Austin — Elon Musk said fabs are 'hard' but necessary for AI5/Dojo/FSD and indicated the project needs $100M+ in capex (x.com) (x.com). The move underscores Tesla’s push for vertical control of its silicon stack rather than relying entirely on external ASIC vendors (x.com).
Elon Musk posted “Terafab Project launches in 7 days” on March 14, setting a March 21, 2026 start tied to Tesla’s Austin Gigafactory north‑campus expansion. (tomshardware.com)) Industry reporting and analyst notes say the March 21 event is the project’s public launch or groundbreaking rather than a fully operational semiconductor fab, with commercial wafer production expected years later. (forbes.com)) Multiple outlets peg the full build cost in the tens of billions: several reports cite a $20–$25 billion estimate while one Morgan Stanley analysis published in media pegged potential capex at $35–$40 billion. (fintechweekly.com)) Tesla’s stated production goals include as many as 100–200 billion custom AI and memory chips per year and an ambition to reach advanced process nodes such as 2‑nanometer for future AI5 class chips. (forbes.com)) Elon Musk has publicly discussed existing supply deals and potential partners — Samsung has been mentioned in prior talks and Musk has hinted at possible cooperation with Intel on manufacturing or packaging — according to industry reporting. (electronicsweekly.com)) Tesla first disclosed Terafab on its January 28, 2026 earnings call and company filings show CFO Vaibhav Taneja acknowledged the full Terafab cost was not fully included in the company’s then‑announced 2026 capex plan. (fintechweekly.com)) Financial markets reacted to the launch news with Tesla shares rising roughly 0.6% in early trading, a move reported alongside commentary that investors are pricing in the long‑term scale implications of in‑house silicon.
