One Factory to Rule Them All: How Musk’s Terafab Could Rewrite the Scale of U.S. Chip Production

The global race for artificial intelligence supremacy is rapidly becoming a race for semiconductor manufacturing capacity. AI models require vast amounts of computing power, data centers are consuming more chips than ever, and governments are increasingly viewing semiconductor production as a matter of national security. 

Against that backdrop, Elon Musk has unveiled perhaps the most ambitious manufacturing proposal yet: a single U.S. facility capable of dramatically expanding domestic chip output at a scale the industry has never seriously attempted in one location. If it works, it could reshape the competitive landscape for decades.

A Factory Designed Around Extreme Scale

According to Musk, the proposed Terafab facility would span roughly 100 million square feet. To put that into perspective, that’s about 10 times larger than Gigafactory Texas, already one of the world’s largest manufacturing facilities. Musk has framed the project as a direct answer to structural semiconductor constraints, stating that “fundamentally, Terafab is about scale.”

Yet, the scale extends far beyond the building itself. Musk says the facility would generate 1 terawatt of chip output annually. From a logic chip perspective, that translates to approximately 1 billion chips per year. But that’s just the high-performance compute chips produced. Ultimately, the goal is to be producing a mind-boggling 100 billion to 200 billion total chips annually when operating at full scale.

Musk suggested current U.S. fabrication capacity sits at roughly 0.5 “terawatt-equivalent” of chip output annually. In that framing, a fully scaled Terafab could double national production from a single site in Texas.

That would place the facility in direct competition with global leaders in advanced manufacturing, including Taiwan Semiconductor Manufacturing (NYSE:TSM | TSM Price Prediction), Samsung Electronics, and a reshaping Intel (NASDAQ:INTC), which is already partnered in early discussions around Terafab development.

Supply Is Not the Only Constraint

AI infrastructure demand continues to scale aggressively, with hyperscalers expanding training clusters and inference capacity across cloud platforms. Tesla’s autonomy stack, SpaceX’s satellite network, and Musk’s xAI efforts all represent internal demand channels that could absorb substantial portions of production.

According to Musk, all the current fabrication facilities on Earth only produce about 2% of what his conglomerate of projects need, “and we need the chips, so we’re going to build the Terafab.”

That creates a structural difference from past chip cycles. Instead of relying purely on external customers, Terafab is designed to serve Musk’s vertically integrated ecosystem spanning vehicles, robotics, AI training, and potentially long-duration compute systems tied to Musk’s emerging “data centers in space” concept.

Is It Achievable?

The enormity of such an undertaking is difficult to grasp, yet there do seem to be a number of practical roadblocks — at least today. Cost could be the primary one. Estimates from Bernstein analysts suggest building enough chip capacity for one terawatt of annual compute would cost between $5 trillion and $13 trillion. Raising even $5 trillion would not be easy.

Of course, Musk isn’t talking about producing 100 billion chips annually right away. Not even 1 billion chips. Initial output is targeting 100,000 wafers per month to start. Still, it might have difficulty finding the necessary labor, materials, and equipment to operate the facility.

For example, a 100,000 wafer starts per month leading-edge fab typically requires about 20 extreme ultraviolet lithography (EUV) machines that only ASML (NASDAQ:ASML) makes. Terafab might require 50 to 100 EUV machines for the suggested 1 billion chips a year, and if fully scaled, possibly as many as 400 machines. 

Last year, ASML sold 48 EUV lithography machines. It is looking to sell 60 machines this year, and 80 next year.

Key Takeaway

In short, the Terafab story is not about a single factory doubling U.S. chip production — it is about redefining what “production” means when logic equivalence, total chip volume, and vertically integrated demand all collide.

For investors, the signal is clear even if the execution is uncertain. Musk is not positioning Terafab as a participant in the semiconductor market. He is positioning it as an attempt to rebuild the supply chain around his own technology ecosystem. Whether that becomes a structural shift in global chip economics — or an overextended ambition constrained by physics and capital — will depend entirely on execution over the next decade.
