The US says ASML's top chip tool may be in China. ASML says it isn't
There's a commercial logic that cuts against the idea that ASML would risk its export license to arm a Chinese customer. Commerce Secretary Howard Lutnick has, in a series of recent meetings, told senior ASML executives he's concerned that one of the Dutch chipmaker's extreme ultraviolet lithography machines - the EUV systems that are the only tools on Earth capable of printing the most advanced semiconductor patterns - may have ended up in China . That would be a major breach of export controls that have barred ASML from selling EUV to China since the first Trump administration.
Key Takeaways
- Senior administration officials told Bloomberg they have evidence that ASML shipped EUV-related components and transport equipment to China, though they've declined, repeatedly, to show it - to Bloomberg or, apparently, to ASML itself.
The company says no such machine exists in China and has never existed there.
- ASML is a Dutch company most people have never heard of, but it is, by a wide margin, the most important company in the global AI buildout that isn't named Nvidia or one of the hyperscalers.
It makes the only machines on the planet capable of EUV lithography - the process of printing the microscopic circuit patterns that define the most advanced chips.
- That scale is exactly why the China question matters so much.
If even one EUV machine made it into Chinese hands, it would represent one of the most consequential breaches of the export-control regime the U.
- He argued the only reason ASML could build an EUV machine at all was that 80% of it already existed from decades of prior knowledge, and that solving the one genuinely new problem - generating EUV light itself - took 20 years on its own.
His broader point seemed to be that you can't reverse-engineer a machine you've never had, and nobody in China has had one.
- ASML expects roughly 20% of its 2026 revenue to come from already-permitted sales to China.
Stats & Key Facts
- #That monopoly has made ASML Europe's most valuable public company, with a market capitalization that has been trading in the neighborhood of $700 billion as of this week, up sharply over the past year on the back of insatiable AI-driven chip demand.

The Commerce Department didn't respond to Bloomberg's questions about whether it has evidence of an actual EUV system on Chinese soil.
You might think this isn't worth paying attention to if you're outside the chip industry, but it is. ASML is a Dutch company most people have never heard of, but it is, by a wide margin, the most important company in the global AI buildout that isn't named Nvidia or one of the hyperscalers. It makes the only machines on the planet capable of EUV lithography - the process of printing the microscopic circuit patterns that define the most advanced chips.
Every cutting-edge processor made by TSMC, the foundry behind Nvidia's and Apple's chips, depends on ASML tools that took the company roughly two decades and untold billions to develop. There is, at present, no second supplier. That monopoly has made ASML Europe's most valuable public company, with a market capitalization that has been trading in the neighborhood of $700 billion as of this week, up sharply over the past year on the back of insatiable AI-driven chip demand.
