The US says ASML’s top chip tool may be in China. ASML says it isn’t

According to Bloomberg, U.S. Commerce Secretary Howard Lutnick has, successful a bid of caller meetings, told elder ASML executives he’s acrophobic that 1 of the Dutch chipmaker’s utmost ultraviolet lithography machines — the EUV systems that are the lone tools connected Earth susceptible of printing the astir precocious semiconductor patterns — may person ended up successful China. That would beryllium a large breach of export controls that person barred ASML from selling EUV to China since the archetypal Trump administration.

It’s a superior claim. Senior medication officials told Bloomberg they person grounds that ASML shipped EUV-related components and transport instrumentality to China, though they’ve declined, repeatedly, to amusement it — to Bloomberg or, apparently, to ASML itself. The institution says nary specified instrumentality exists successful China and has ne'er existed there. The Commerce Department didn’t respond to Bloomberg’s questions astir whether it has grounds of an existent EUV strategy connected Chinese soil.

You mightiness deliberation this isn’t worthy paying attraction to if you’re extracurricular the spot industry, but it is. ASML is simply a Dutch institution astir radical person ne'er heard of, but it is, by a wide margin, the astir important institution successful the planetary AI buildout that isn’t named Nvidia oregon 1 of the hyperscalers. It makes the lone machines connected the satellite susceptible of EUV lithography — the process of printing the microscopic circuit patterns that specify the astir precocious chips.

Every cutting-edge processor made by TSMC, the foundry down Nvidia’s and Apple’s chips, depends connected ASML tools that took the institution astir 2 decades and untold billions to develop. There is, astatine present, nary 2nd supplier. That monopoly has made ASML Europe’s astir invaluable nationalist company, with a marketplace capitalization that has been trading successful the vicinity of $700 cardinal arsenic of this week, up sharply implicit the past twelvemonth connected the backmost of insatiable AI-driven spot demand.

That standard is precisely wherefore the China question matters truthful much. If adjacent 1 EUV instrumentality made it into Chinese hands, it would correspond 1 of the astir consequential breaches of the export-control authorities the U.S. has built implicit the past respective years to support precocious AI capableness retired of Beijing’s subject and concern base.

I sat down with ASML CEO Christophe Fouquet six weeks ago, good earlier this communicative broke, and asked him straight astir the China question.

Fouquet told maine ASML tracks each instrumentality it has ever shipped — they’re either successful progressive usage with monitored customers oregon person been dismantled and returned to the company. He said the steadfast built an interior firewall years ago: employees who tin entree EUV technology, documentation, and grooming are walled disconnected from those who can’t, and ASML’s China-based unit beryllium connected the incorrect broadside of that partition by design. He argued the lone crushed ASML could physique an EUV instrumentality astatine each was that 80% of it already existed from decades of anterior knowledge, and that solving the 1 genuinely caller occupation — generating EUV airy itself — took 20 years connected its own. His broader constituent seemed to beryllium that you can’t reverse-engineer a instrumentality you’ve ne'er had, and cipher successful China has had one.

There’s besides a simpler commercialized logic that cuts against the thought that ASML would hazard its export licence to softly limb a Chinese customer. ASML does merchantability older-generation heavy ultraviolet tools to China — cogwheel it archetypal shipped a decennary agone — but Fouquet framed that explicitly arsenic a protective calculation, not a loophole. The idea, helium suggested, is that it keeps capable of a generational spread that customers tin inactive bash concern — but without manufacturing its ain aboriginal competitor. ASML expects astir 20% of its 2026 gross to travel from already-permitted income to China. Risking the EUV prohibition wholly would enactment that revenue, and the company’s lasting arsenic the astir invaluable monopoly successful European industry, connected the enactment implicit a azygous amerciable sale.

None of this proves the allegations are false. The authorities hasn’t yet made its grounds public, and it’s worthy withholding judgement until it does.

The Commerce Department, nether Lutnick’s leadership, agreed precocious past twelvemonth to enactment up to $150 cardinal of payer money into xLight, a startup processing a next-generation light-source exertion that’s been written astir arsenic a semipermanent situation to the halfway of ASML’s EUV monopoly. xLight’s ain CEO told maine past year that the institution sees itself arsenic a aboriginal spouse to ASML, not a rival, gathering hardware meant to plug into ASML’s machines alternatively than regenerate them. When I enactment that framing to Fouquet successful May, helium was polite astir it but unconvinced; ASML, helium made clear, doesn’t spot itself arsenic needing xLight’s exertion to support its lead.

Does that person thing to bash with wherefore Lutnick is abruptly pressing ASML connected EUV? Nothing nationalist connects the two. It could beryllium wholly unrelated. But a national authoritative scrutinizing a monopoly portion his ain bureau has wealth riding connected a startup angling to amended that monopoly’s halfway exertion is worthy examining.

xLight isn’t the lone extracurricular stake connected the aboriginal of lithography. Peter Thiel — who has his ain long-running ties to Trump’s governmental orbit — has backed Substrate, a abstracted startup explicitly pursuing its ain EUV-rival technology, with ambitions to vie with ASML much straight than xLight says it intends to.

As Bloomberg notes, a bipartisan measure moving done Congress would spell overmuch further than EUV — it calls for an effectual prohibition connected each of ASML’s heavy ultraviolet (DUV) shipments to China, the little precocious lithography tools that relationship for astir a 5th of the company’s expected 2026 revenue. The measure cleared a cardinal committee successful April, and the Trump medication hasn’t taken a ceremonial presumption connected it.
