Key Takeaways
- Elon Musk revealed the Terafab project will officially begin operations in 7 days at Tesla’s Austin Gigafactory campus
- The chip production facility aims to prevent a potential semiconductor shortage that Musk believes could constrain Tesla’s expansion within 3–4 years
- Meeting Tesla’s ambitious Optimus humanoid robot goals could necessitate over 200 million chips annually — approximately 50 times current requirements
- According to Morgan Stanley’s Andrew Percoco, the fabrication plant could demand investments between $35B–$40B with chip production starting around 2028
- Domestic chip manufacturing is driven by geopolitical supply chain concerns, according to Musk
Shares of Tesla climbed 0.6% during early Wednesday market activity, reaching $401.75, following CEO Elon Musk’s confirmation that the company’s “Terafab” semiconductor manufacturing plant will commence operations on March 21 at the Austin, Texas Gigafactory complex.
The project was initially teased by Musk during a January 2026 earnings call with investors, with the Austin site being confirmed through a March 14 social media post on X. The semiconductor facility will be integrated into Tesla’s massive 2,500-acre Gigafactory Texas property.
The AI industry is about to run out of chips. The world's largest foundries are maxed out and the demand curve is still going vertical.
Tesla’s TeraFab is a bet on a solution no other company in the world has been ambitious enough to try…. build the chips yourself

The fundamental rationale is straightforward: Musk anticipates a chip supply crisis for Tesla. “When I look ahead and say what’s the limiting factor for Tesla growth, if you go 3 or 4 years out, I think it actually is chip production,” he explained to investors during the January call.
He additionally highlighted concerns about memory capacity and AI processing power. “Is there enough AI logic and enough memory, enough RAM for our volume?” Musk questioned during the discussion.
The Strategic Rationale Behind Tesla’s Chip Manufacturing
Morgan Stanley’s Andrew Percoco broke down the calculations. Should Tesla achieve its ambitious Optimus humanoid robot production goal of 100 million-plus units annually, the company would require in excess of 200 million chips each year. This represents more than a 50-fold increase compared to Tesla’s present chip consumption across its vehicle and autonomous taxi operations.
According to Percoco, Tesla’s move toward in-house chip production stems from two primary factors: geopolitical vulnerabilities and the Optimus initiative. Company leadership indicated that AI computational capacity could become a critical constraint within a three-to-four-year timeframe.
Musk addressed the geopolitical dimension explicitly. He emphasized the Terafab must encompass “logic, memory and packaging domestically” as protection against supply chain disruptions. “I think people may be underweighting some of the geopolitical risks,” he stated.
Constructing a semiconductor fabrication facility requires substantial investment and time. As a comparison, Micron’s memory chip plant in Boise began construction in 2022 and won’t reach production capacity until 2027.
Financial Investment and Timeline Projections
Percoco projects Tesla may need to allocate between $35 billion and $40 billion to develop its proprietary chip fabrication capabilities. Under the most favorable circumstances, he anticipates chip manufacturing wouldn’t begin until 2028.
This represents a significant departure from Tesla’s historical capital expenditure patterns. The automaker typically invests less than $10 billion annually on manufacturing facilities and equipment, although the company has announced plans to increase spending to $20 billion in 2026 to support its robotics expansion.
Percoco characterized the fabrication plant as a “Herculean task” and suggested Tesla might alternatively pursue partnerships with established semiconductor manufacturers instead of pursuing independent development. His current rating on Tesla stock is Hold with a $415 price target.
Tesla shares entered Wednesday’s trading session down 11% year-to-date but maintaining a 77% gain over the trailing 12-month period. Both S&P 500 and Dow Jones futures showed modest gains for the day.
The official Terafab launch is scheduled for March 21.
