Have you ever stopped to think about what actually goes into building the incredible AI chips that power everything from chatbots to autonomous systems? We all cheer for Nvidia as it towers over the market, but there’s a quiet giant working behind the scenes without which none of this would be possible. It’s a Dutch company called ASML, and honestly, the more I dig into it, the more I realize just how pivotal they are.
In a world obsessed with flashy GPU announcements and trillion-dollar valuations, ASML often flies under the radar. Yet their machines are the literal foundation for the most advanced semiconductors on the planet. Without them, Nvidia’s groundbreaking designs would remain just that—designs. It’s a fascinating reminder that the real magic in tech often happens in the less glamorous parts of the supply chain.
The Hidden Engine of the AI Era
Let’s start with the basics. Modern chips are mind-bogglingly complex, packing billions of transistors into spaces smaller than a virus. To create those tiny features, manufacturers need something called lithography—the process of “printing” circuit patterns onto silicon wafers using light. It’s like using a super-precise projector to etch designs layer by layer.
But as chips have shrunk over the decades, regular light just doesn’t cut it anymore. That’s where extreme ultraviolet (EUV) lithography comes in. EUV uses light with a wavelength of just 13.5 nanometers—about 1/7000th the width of a human hair. This allows for incredibly fine details, enabling the performance leaps that make today’s AI possible.
Here’s the kicker: ASML is the only company in the world that produces these EUV machines at scale. No one else comes close. Competitors like Nikon and Canon handle older tech for less demanding chips, but for the bleeding-edge stuff? It’s ASML or nothing.
How EUV Actually Works
Picture this: inside one of these behemoths—each the size of a bus and weighing over 100 tons—a powerful laser blasts tiny droplets of molten tin 50,000 times per second. The impact creates a plasma that emits EUV light. That light bounces off ultra-precise mirrors (because no lens can handle EUV wavelengths) and gets projected through a mask onto the wafer.
Every step demands insane precision. The mirrors must stay accurate to within a fraction of an atom. The vacuum environment prevents light absorption. It’s engineering on a whole different level, and ASML has spent decades—and billions—perfecting it.
In my view, this isn’t just impressive tech; it’s borderline miraculous. The fact that humans have built machines capable of manipulating light at this scale never fails to blow my mind.
Lithography is the building block of any chip. Without it, none of the progress we’ve seen would have happened.

And for AI specifically, EUV is non-negotiable. Nvidia’s latest chips rely on process nodes that only EUV can deliver economically. Low-NA EUV handles current generations like Blackwell, while the newer High-NA versions promise even smaller features for tomorrow’s breakthroughs.
ASML’s Unmatched Monopoly
Why hasn’t anyone caught up? Simple: time and money. ASML has invested over three decades and tens of billions into EUV. Rivals would need to replicate that ecosystem—from laser suppliers to mirror polishers—almost from scratch. Analysts I’ve followed estimate it’s a decade-lead at minimum.
- 90%+ market share in advanced lithography
- Sole supplier of EUV systems worldwide
- High-NA EUV already in labs, heading to production soon
- Customers locked in due to massive supply-chain investments
Switching providers mid-race would be catastrophic—like changing engines during a Formula 1 grand prix. Chipmakers have bet everything on ASML’s roadmap. That creates a moat that’s incredibly difficult to breach.
Sometimes I wonder if people truly appreciate how rare this kind of dominance is in tech. Most “monopolies” get chipped away over time, but ASML’s position feels almost unassailable for the foreseeable future.
The Direct Link to Nvidia’s Success
Nvidia designs the brains of AI—those powerful GPUs that train models and run inferences. But they don’t manufacture them. That’s TSMC’s job (with Samsung and Intel playing supporting roles). And TSMC relies heavily on ASML’s machines to produce at 3nm, 2nm, and beyond.
Without ASML’s EUV tools, TSMC couldn’t deliver the density and efficiency Nvidia needs. It’s a chain: Nvidia → TSMC → ASML. Break any link, and the whole thing grinds to a halt. That’s why ASML rides the AI wave just as surely as Nvidia does, even if the spotlight shines elsewhere.
I’ve always found it intriguing how value distributes in supply chains. The designer captures headlines and margins, but the enabler quietly reaps rewards too. ASML’s machines cost hundreds of millions each, and demand keeps soaring.
| ASML Machine Type | Approx. Price (EUR) | Primary Use |
| Low-NA EUV | ~220 million | Current AI chips (e.g. Blackwell) |
| High-NA EUV | 320–400 million | Next-gen nodes (R&D now, production 2027+) |
Those numbers aren’t pocket change. Yet foundries line up to buy them because the alternative—staying behind on performance—is far worse.
Recent Numbers Tell the Story
ASML’s momentum is hard to ignore. In late 2025, bookings exploded—far exceeding expectations—with EUV making up the lion’s share. They shipped dozens of systems last year alone, generating billions in revenue.
Heading into 2026, guidance looks strong: sales projected between 34 and 39 billion euros, up from 2025’s already impressive haul. That’s growth fueled almost entirely by AI demand. Chipmakers are expanding capacity like never before to meet the hunger for compute.
The stock has reflected this confidence. After a solid run in 2025, it kept climbing into the new year, hitting major milestones. Perhaps the most interesting aspect is how resilient it feels—even amid broader market noise.
- Strong Q4 bookings signal robust demand
- EUV revenue expected to surge significantly
- High-NA transition accelerating
- Installed base services adding steady income
- Overall outlook points to multi-year growth
Of course, nothing’s guaranteed. Geopolitical tensions, especially around exports, add uncertainty. But ASML’s position seems solid enough to weather storms better than most.
Looking Ahead: High-NA and Beyond
The next big leap is High Numerical Aperture EUV. These machines offer even finer resolution, paving the way for sub-2nm nodes. Labs are already experimenting, with volume production eyed for 2027-2028. Early adopters like Intel could lead the charge.
What excites me most is how this extends the roadmap. For years, people worried Moore’s Law was dying. ASML’s innovations keep it alive, enabling more powerful AI, better efficiency, and entirely new applications we haven’t imagined yet.
Perhaps that’s the ultimate point: ASML isn’t just supporting Nvidia’s boom—it’s enabling the entire industry’s future. In a sense, they’re the quiet architect of what’s coming next.
So next time you read about another Nvidia milestone, spare a thought for the Dutch engineers who make it all possible. Their work might not grab headlines, but without it, the AI revolution would look very different. And personally? I think that’s pretty cool.
