Key Highlights
- Elon Musk announced Terafab, a collaborative semiconductor initiative involving Tesla, SpaceX, and xAI, planned for construction at Giga Texas in Austin.
- The facility aims to produce 2-nanometer chips designed for Tesla’s FSD technology, Optimus robots, and SpaceX satellite systems.
- Projected initial expenditure ranges from $20–$25 billion, operating independently of Tesla’s established 2026 capital spending framework.
- Morgan Stanley analysts estimate overall investment may climb to $35–$45 billion, with initial chip manufacturing expected around mid-2028 at the earliest.
- Tesla shares finished Monday’s trading session up 3.5% at $380.85.
Elon Musk introduced Terafab during a Saturday evening presentation at a former power plant location in Austin, Texas. This collaborative initiative brings together Tesla, SpaceX, and xAI, with plans to consolidate all semiconductor manufacturing phases within a single facility.

Musk’s message was clear and direct: existing chipmakers such as TSMC and Samsung cannot match the production speed required for Tesla and SpaceX operations. “We either build the Terafab or we don’t have the chips,” he stated.
The manufacturing complex is designated for the North Campus area of Giga Texas, within a structure planned to exceed the dimensions of the current Giga Texas facility — already recognized as among the planet’s largest buildings.
Terafab will focus on manufacturing two distinct chip varieties. The first is an edge-inference processor designed for Tesla’s Full Self-Driving technology, Optimus robots, and Robotaxi operations. The second is a reinforced version engineered for space applications, powering SpaceX satellites and orbital computing facilities.
Tesla shares concluded Monday at $380.85, representing a 3.5% gain for the session. The S&P 500 advanced 1.2% and the Dow increased 1.4%, as broader markets rallied following President Trump’s announcement that the U.S. and Iran engaged in discussions aimed at reducing Middle East tensions.
Optimus Production Volumes Drive Chip Requirements
The projected figures for Optimus production are remarkable. Morgan Stanley analyst Andrew Percoco highlighted that Giga Texas is anticipated to achieve production capacity for 10 million humanoid robots annually. This volume would necessitate 20 million chips — approximately six times Tesla’s present chip requirements across its entire automotive portfolio.
Should Tesla achieve its extended-term objective of 100 million Optimus robots each year, chip demand would escalate to over 200 million units — exceeding 50 times its current combined requirements for automotive and Robotaxi applications.
Musk articulated his goal to generate more than one terawatt of AI computing capability annually. He anticipates 80% of Terafab’s production will ultimately serve space-based operations, where SpaceX intends to manage AI computing workloads that hyperscalers presently execute on Earth.
Wall Street Analysts Express Measured Optimism
Barclays analyst Dan Levy characterized the magnitude of Musk’s objectives as dramatically exceeding market expectations. “With a target of 1 terawatt of compute capacity, it would be 50 times current global AI compute,” Levy observed.
Morgan Stanley’s Percoco described Terafab as a sound strategic decision, while emphasizing the substantial financial commitment. He projects total capital requirements at $35–$45 billion. The preliminary $20–$25 billion estimate Musk referenced remains separate from Tesla’s existing 2026 capital expenditure roadmap.
Terafab will pursue 2-nanometer manufacturing technology — representing the most sophisticated production node available globally, which TSMC has only recently begun scaling. Morgan Stanley anticipates initial chip production would commence no earlier than mid-2028 under an accelerated development schedule.
Musk offered no definitive construction timeline or production benchmarks. He indicated the initiative would commence with prototyping phases and infrastructure validation.
Prior to Monday’s market session, Tesla stock had declined 18% year to date while gaining 48% over the trailing twelve months. The shares currently trade at approximately 190 times projected 2026 earnings.
SpaceX completed its merger with xAI earlier this year and may pursue an initial public offering as early as this spring.
