ASML chief warns of possible supply disruptions as Musk's Terafab joins the queue

ASML is the world's only maker of EUV lithography systems, without which advanced semiconductors cannot be produced. CEO Christophe Fouquet has publicly warned that growing demand from new large-scale projects, including Elon Musk's Terafab, creates a real risk of equipment supply disruptions.

A monopoly with no workaround

ASML holds a unique position in the global technology supply chain. It is the only company that builds EUV (Extreme Ultraviolet) lithography machines. Without this equipment, chips at 3 nm and below cannot be made, and every modern AI accelerator is built on such nodes, including NVIDIA's H100 and B200.

ASML's production capacity is tightly limited. One High-NA EUV machine costs about $370 million, and the company ships only a few dozen of them a year. Each contains roughly 100,000 components from hundreds of suppliers around the world. Any disruption in that chain delays the whole queue of customers. Output cannot be scaled up in a year or two: the entire cycle, from Carl Zeiss precision optics to laser sources, takes years to retool.

Terafab and the fight for equipment

Terafab is Elon Musk's ambitious project to build a large-scale AI chip manufacturing hub. Unlike most AI companies, which rent capacity at TSMC or Samsung fabs, Terafab envisions its own semiconductor production. That means ordering EUV machines directly from ASML and joining an already overloaded queue.

Launching a fab of this scale requires:

• Several dozen High-NA EUV machines, with multi-year approval and delivery cycles
• Long-term contracts with highly specialized suppliers of laser sources, precision optics and control systems
• Export licenses: EUV technology falls under US restrictions as a dual-use product
• Thousands of engineers with rare semiconductor manufacturing skills

Terafab is also competing for ASML's resources with TSMC (building a fab in Arizona), Intel (the IDM 2.0 program), Samsung, and government programs in Japan, South Korea and the EU. Global demand for EUV equipment today far exceeds the company's production capacity.

What Fouquet actually said

The ASML CEO did not criticize Terafab as a project and did not refuse to work with Musk. His words were measured: a management signal to investors and partners that production load must be kept under control.

"We must make sure we don't run into supply limitations while serving new projects like Terafab,"

Fouquet said.

The subtext for the market is clear: signing a contract with ASML does not mean getting equipment on time. At current levels of global demand, EUV delivery slots have become a strategic asset alongside capital and technology. Companies that did not secure a place in the queue early risk losing years in the AI infrastructure race.

What this means

Fouquet's warning exposes a structural limit of the current AI race. The bottleneck is not cloud providers' capacity, software platforms, or even the volume of investment. It sits in a few dozen production lines at a single Dutch company, which cannot be scaled up quickly. Anyone who did not order EUV equipment early risks waiting in line while competitors are already producing next-generation chips.
