# ASML The Dutch company that holds an absolute monopoly on extreme ultraviolet (EUV) lithography — the technology required to manufacture every advanced semiconductor chip in the world. ASML controls 100% of the global EUV market and approximately 83% of all lithography equipment sales. No EUV machine, no leading-edge chips. No leading-edge chips, no frontier AI models. ASML is the single most critical chokepoint in the global technology supply chain. Headquartered in Veldhoven, Netherlands, ASML's EUV machines cost over $200 million each, weigh 180 tons, require multiple Boeing 747s to ship, and take months to install. Each machine uses a tin-droplet plasma process to generate extreme ultraviolet light at 13.5 nanometers — a wavelength so short it must operate in a near-perfect vacuum and can only be directed by multilayer mirrors (not lenses). No other company on earth has replicated this capability. ASML spent over two decades and tens of billions of dollars developing it. ## The AI infrastructure bottleneck Every [[NVIDIA]] H100, H200, and Blackwell GPU — the chips powering the AI boom — is manufactured by [[TSMC]] using ASML's EUV lithography systems. Every [[Intel]] and [[Samsung]] leading-edge process node requires the same machines. ASML's 2026 revenue forecast is €36–40 billion, with projections reaching $71 billion by 2030, driven almost entirely by AI-related demand for advanced chips. This means ASML is the upstream dependency that every frontier AI lab, cloud provider, and defense contractor ultimately relies on. The company doesn't build the chips, train the models, or run the datacenters — it builds the machine that builds the machine that makes it all possible. Its monopoly position makes it arguably more strategically important than any individual chip designer or AI company. ## Export controls and the China question ASML sits at the center of the [[Chip Export Controls]] regime the vault tracks. The US, Netherlands, and Japan agreed in January 2023 to restrict exports of advanced lithography equipment to China — effectively preventing China from manufacturing leading-edge chips domestically. ASML stopped shipping its most advanced EUV systems (the Twinscan NXE and EXE series) to Chinese customers, and in 2025 expanded restrictions to cover some older deep ultraviolet (DUV) systems as well. The impact is visible in ASML's revenue: China's share dropped from 33% in 2025 to 19% in Q1 2026 — a deliberate policy outcome. The restriction is the single most effective technology denial measure in the current US-China competition, more consequential than any chip design ban, because it attacks the manufacturing capability rather than the end product. But the policy creates tension between the US and the Netherlands. In June 2026, Dutch Trade Minister Sjoerd Sjoerdsma lobbied US Commerce Secretary [[Howard Lutnick]] against expanding restrictions further, particularly the proposed MATCH Act (Multilateral Alignment of Technology Controls on Hardware) that would impose a blanket ban on semiconductor manufacturing equipment exports to all of China. The Netherlands is caught between alliance loyalty and the economic reality that ASML is the country's most valuable company and China was its largest customer. ASML's CEO has warned that tighter restrictions will push China toward developing competing lithography tools — a prospect that would take years but is not impossible, particularly with China's demonstrated willingness to spend unlimited resources on strategic technology independence. The export control debate around ASML is thus a real-time test of the [[Splinternet]] thesis: can technology denial work permanently, or does it merely delay and motivate the adversary? ## KB relevance ASML matters to the vault as the physical chokepoint underlying every AI-related technology restriction the vault tracks. The [[Chip Export Controls]] are enforcement mechanisms; ASML's monopoly is the leverage that makes them work. The [[Anthropic Model Export Directive]] restricted access to frontier AI models; ASML restrictions ensure China can't just build its own hardware to run equivalent models. The [[Dual-Use AI]] debate is ultimately constrained by who can manufacture the chips that run AI workloads — and that question passes through a single company in the south of the Netherlands. The company also connects to the Dutch intelligence agencies in the vault: the [[AIVD]] and [[MIVD]] are responsible for protecting ASML from espionage (Chinese intelligence collection targeting ASML's technology has been extensively documented) and for monitoring technology transfer risks. ## See Also - [[Chip Export Controls]] — the restriction regime ASML's monopoly enables - [[TSMC]] — the foundry that uses ASML machines to make the world's chips - [[NVIDIA]] — the AI chip designer whose products depend on ASML lithography - [[Dual-Use AI]] — the framework for technology serving both civilian and military purposes - [[Splinternet]] — the technology bifurcation ASML restrictions accelerate - [[AIVD]] — Dutch intelligence protecting ASML from espionage - [[Silicon Valley AI Ecosystem]] — the industry that depends on ASML's machines - [[US Government Technology Restrictions Timeline]] — the policy arc from crypto wars through chip controls
