ASML Denies US Allegation That EUV Machine Reached China
TL;DR
- Lutnick told ASML executives US officials hold evidence of EUV-related component shipments to China but declined to share the underlying records.
- ASML circulated a lobbying document titled 'No indication of any ASML EUV System in China,' cataloguing all 314 machines with none in China.
- Lutnick's Commerce Department separately invested $150 million in xLight, a US startup developing competing EUV technology, creating a direct conflict of interest.
ASML holds a monopoly so complete that for practical purposes there is no advanced semiconductor industry without it. The Dutch company is the sole source of extreme ultraviolet lithography machines, the equipment that makes it physically possible to manufacture the chips inside every high-end AI accelerator and smartphone processor. That concentration of indispensability is why a claim now circulating at the highest levels of US trade policy carries the weight it does: as TechCrunch reports citing Bloomberg, US Commerce Secretary Howard Lutnick has raised concerns directly with ASML executives that one of those machines may have reached China, in violation of export controls in place since the first Trump administration.
ASML's denial is categorical. CEO Christophe Fouquet has said the company tracks every machine it ships, and that no EUV system exists in China or has ever existed there. The company maintains an internal firewall that keeps China-based employees on the restricted side of EUV access, a structural control it cites as evidence of ongoing compliance. Senior US administration officials, per the reporting, claim to possess evidence that ASML shipped EUV-related components and transport equipment to China, though that evidence has not been publicly disclosed.
The commercial stakes around ASML's China relationship are already under pressure on a separate track. The company reportedly expects roughly 20% of its 2026 revenue from already-permitted sales to China, which cover older DUV machines rather than EUV. A bipartisan congressional bill that would ban those DUV shipments too cleared a key committee in April. Adding an unresolved EUV allegation to that legislative pressure creates real risk to a revenue line the company clearly wants to protect.
The honest caveat is that everything downstream of the Bloomberg scoop is unresolved. No evidence has been made public, no regulatory action has been announced, and ASML's denial is firm. This is an allegation, not a finding, and ASML has a substantial financial incentive to have stayed on the right side of the rules. Take the specifics as reported rather than settled, and watch whether the Commerce Department moves beyond a private conversation to an actual enforcement posture.
What the episode does clarify is the logic behind the US government's parallel bet on alternatives. The Commerce Department has invested up to $150 million in xLight, a startup working on next-generation light-source technology that could eventually challenge ASML's approach. Peter Thiel has backed Substrate, a separate effort in the same space. Whether or not the current allegations resolve into anything concrete, the US clearly wants a world where a single Dutch company is not the chokepoint for every advanced chip on earth, and this story is likely to accelerate funding and urgency on that front.
