Elon Musk wants to build a chip factory that makes more semiconductors in a year than the entire world currently produces for artificial intelligence. Not modestly more. Fifty times more.
That is the explicit goal of Terafab, the AI chip manufacturing complex Musk announced in Austin on March 21, and it is the number most other outlets buried. Intel confirmed on Tuesday that it has joined the project, bringing its manufacturing expertise to what Musk has described as an effort to produce one terawatt of compute annually. One terawatt is roughly fifty times what all the world's major chipmakers combined currently produce each year specifically for AI applications, according to New Atlas. The partnership sent Intel's shares up nearly 3%.
Nobody else led with that number. Every other news organization led with the partnership and the stock pop. But the stock pop is noise. The terawatt figure is the signal, because it tells you whether Terafab is a real industrial bet or a Very Large Press Release.
The scale Musk is describing has no precedent in commercial semiconductor manufacturing. The world's most advanced fabs, operated by TSMC and Samsung, produce chips at a small fraction of that volume. A full-scale Terafab would aim for one million wafer starts per month, producing between 100 billion and 200 billion custom AI and memory chips per year, according to Wikipedia's compilation of Musk's stated targets. The initial prototype fab, to be built at Tesla's GigaTexas site in Austin, targets 100,000 wafer starts per month before scaling up. The project cost is estimated at $20 billion to $25 billion.
The chip at the center of this is Tesla's AI5, the fifth generation of its in-house silicon, which is among the first products the pilot facility will produce. Small-batch production is anticipated in 2026, with volume production targeted for 2027.
This is also, explicitly, a humanoid robot story. Musk has said he expects Tesla's Optimus robot to hit the market in 2027, and has projected that Tesla could eventually produce as many as 10 billion Optimus units per year. Barclays analysts forecast the broader humanoid robot market could grow from roughly $2 billion to $3 billion today to at least $40 billion by 2035, and potentially as much as $200 billion. Terafab is the chip supply chain Musk is building to make that vision physically possible, not just financially plausible.
Intel's role is specific: the company will help Terafab refactor the technology inside a chip factory, a process stage that makes chips more powerful or reliable, Bloomberg reported. Intel is not providing capital. It is providing expertise, at a moment when its own position in the semiconductor industry is precarious. CEO Lip-Bu Tan is pursuing aggressive restructuring that includes cutting approximately 21,000 to 25,000 positions, roughly 15% to 25% of its core workforce, according to Fortune. The U.S. government is now Intel's largest shareholder, having poured billions into the company alongside Nvidia. Hosting Musk at its campus the weekend before Tuesday's announcement was a deliberate signal that Intel still has something the most ambitious chip project on earth wants.
There is a second number that almost nobody is discussing: $1.75 trillion. That is SpaceX's target valuation for its IPO, which Reuters reported on Tuesday with a listing expected around June 2026. SpaceX merged with Musk's AI company xAI in February 2026 at a combined valuation of $1.25 trillion. The $500 billion step-up in six months is partly a function of the Terafab announcement and the broader Musk empire across rockets, AI, and automotive. But it is also a number that will be stress-tested the moment the roadshow begins.
The terawatt figure is the most honest test of what Terafab actually represents. The goal is not incremental. It is a bet that global AI compute demand will grow enough to fill a factory that would itself reshape that demand. Whether 1 terawatt per year is a self-defining prophecy or a geometric miscalculation is the central question the next 18 months of chip production data will answer.
What to watch: whether TSMC or Samsung responds to Terafab's scale claims, and whether any independent semiconductor analyst is willing to put a number on how long 1 terawatt of annual AI compute would take to absorb into the market at current growth rates. Musk's track record on manufacturing timelines is not uniform. The stock pop is real. The terawatt claim is the reason the story is worth reading.
