Key Highlights

Elon Musk revealed “Terafab,” an ambitious semiconductor manufacturing venture in Austin, Texas, uniting Tesla, SpaceX, and xAI
Two distinct chips will be manufactured — one for Tesla’s cars and Optimus robots, another for space-based AI satellites
According to Musk, current worldwide chip production satisfies merely 3% of his companies’ projected requirements
First chips expected in late 2027, with full-scale manufacturing planned for 2028
Tesla shares declined approximately 2–3% during premarket hours following the revelation

Elon Musk revealed ambitious plans for a substantial semiconductor manufacturing operation dubbed “Terafab” over the weekend, confirming it as a collaborative effort among Tesla, SpaceX, and xAI. The disclosure triggered a decline in Tesla’s stock price during Monday’s premarket session.

The announcement took place at a decommissioned power facility in Austin, Texas. Musk characterized Terafab as comprising two distinct manufacturing plants, each dedicated to producing a unique chip architecture.

The first chip will serve Tesla’s automotive fleet and the Optimus humanoid robot platform. The second will support AI processing in orbital environments, engineered to withstand extreme conditions and elevated operating temperatures.

According to Musk, current worldwide semiconductor manufacturing capacity would fulfill just 3% of what his enterprises will ultimately require. While acknowledging Samsung, TSMC, and Micron as existing suppliers, he emphasized that future demand will surpass total global production capabilities.

The “Terafab” designation reflects Musk’s ambition to manufacture chips requiring one terawatt of power consumption — approximately equal to one billion Nvidia Blackwell processors annually.

SpaceX’s participation came as a surprise to many observers. The aerospace company, which recently consolidated with xAI, is gearing up for a public offering that analysts estimate could reach a $1.75 trillion valuation.

Financial Investment and Production Timeline

Early-stage development will demand tens of billions in capital expenditure. Tesla has already earmarked approximately $20 billion for new equipment purchases in 2026, a significant increase from the sub-$9 billion spent in 2025. Terafab investments are separate from these existing allocations.

Musk’s timeline calls for initial chip production in late 2027, ramping to maximum output throughout 2028. As reference, semiconductor fabrication plants generally require roughly three years from construction start to volume production.

Musk indicated Terafab will ultimately deliver one terawatt of computational power annually. To put this in perspective, the entire U.S. currently generates approximately half that capacity.

Space-Based Computing Takes Priority

One notable revelation: Musk projects that 80% of Terafab’s production will support space-based artificial intelligence computing. SpaceX intends to replicate in orbit what cloud computing giants currently perform in terrestrial data centers.

The facility will concentrate on two-nanometer process technology, representing the cutting edge of current semiconductor manufacturing.

Tesla’s stock price fell roughly 3.2% on Monday. The company entered the week with an 18% year-to-date decline, though maintaining a 48% gain over the trailing twelve months.

Shares currently trade at approximately 190 times projected 2026 earnings, with market valuations incorporating anticipated AI-driven revenue from autonomous taxi services and robotics divisions.

Tesla initiated its robo-taxi program in Austin during June but has yet to expand operations to additional markets. The company is simultaneously developing a third-generation Optimus robot.

Musk has not announced a specific construction start date for Terafab.
