ASML Faces Twin Headwinds: OpenAI Growth Fears and a 150-Day Washington Ultimatum

ASML shares dip after OpenAI growth doubts emerge, but structural AI demand remains strong. A looming US bill targeting DUV lithography sales to China poses a greater long-term risk.

The Dutch lithography giant ASML is navigating a rare moment of turbulence, caught between a sudden market jolt from the AI sector and a legislative time bomb ticking in Washington. The stock, which had more than doubled over the past twelve months, shed as much as 4.7 percent in a single session on Tuesday before paring losses to 3.3 percent. At roughly €1,190, the shares now sit just below their 50-day moving average of €1,202 and roughly eight percent off the 52-week high.

The immediate trigger was a Wall Street Journal report that OpenAI finance chief Sarah Friar had internally acknowledged the company had missed its user growth and revenue targets. The report also suggested Friar had raised doubts about whether OpenAI could sustain its enormous commitments to computing capacity over the long haul. OpenAI CEO Sam Altman and Friar dismissed the story as “ridiculous” in a joint statement, but the market response was tepid at best. The selloff hit ASML especially hard because chip stocks had just completed an extraordinary 18-session winning streak, leaving the sector vulnerable to profit-taking.

Yet the OpenAI episode may prove to be a short-term noise. The structural demand for ASML’s machines is underpinned by capital spending from the hyperscalers. Amazon, Microsoft and Meta are collectively pouring between $115 billion and $200 billion annually into AI infrastructure, regardless of whether OpenAI hits its internal targets. Whoever wins the AI race needs advanced logic and memory chips, and those chips are made on ASML’s EUV and DUV tools.

A more persistent cloud hangs over ASML’s China business. The MATCH Act, a bipartisan US bill introduced in April 2026, cleared the House Foreign Affairs Committee on April 22 as part of what lawmakers describe as the largest export control package in congressional history. The legislation takes direct aim at deep-ultraviolet immersion lithography — the very technology China cannot produce domestically and ASML’s most important product line. An earlier provision targeting cryogenic etching tools was stripped out in an amendment, leaving DUV lithography systems as the sole category facing a nationwide sales ban to China.

The bill gives the Netherlands and Japan a 150-day window to align their export rules with US standards. If diplomacy fails, Washington can extend the Foreign Direct Product Rule, giving the US jurisdiction over any machine containing even a single American component, regardless of where it was built. The legislative path remains long: the bill must still clear the full House and the Senate, a process that could take months.

China was ASML’s largest single market in 2025, accounting for 33 percent of total revenue. The company has already baked a decline into its own forecasts, projecting that China will contribute only around 20 percent in 2026 — a drop that reflects existing restrictions. Ben Barringer, a technology analyst at Quilter Cheviot, estimates the direct damage from the MATCH Act would be manageable. The older DUV machines in the crosshairs represent roughly 10 to 15 percent of total revenue, with China buying about half of those. The net effect: a revenue hit of around five percent that should fade over time.

ASML’s own guidance for 2026 calls for net sales of €36 billion to €40 billion and a gross margin between 51 and 53 percent. Management has stressed that the range already accounts for possible export control scenarios. Tailwinds from AI demand remain strong: Taiwan Semiconductor is planning capital expenditure near the top end of its guidance range, a roughly 37 percent increase year-on-year, which drives demand for ASML’s EUV machines — equipment untouched by the US restrictions.

Beyond the core lithography business, ASML has been building a strategic position in AI through its roughly 11 percent stake in Mistral AI, the French artificial intelligence company. Singapore telecommunications group Singtel recently announced a partnership with Mistral to expand Singapore’s AI infrastructure across finance, healthcare and public administration. ASML’s involvement lends industrial credibility to the project and signals that the company’s AI engagement extends well beyond selling chip-making tools.

The coming months will hinge on how the Dutch government responds to the 150-day ultimatum and whether Washington ultimately moves to unilateral action. For now, ASML’s stock has gained over 20 percent since the start of the year, but the twin pressures of a growth scare in AI and a geopolitical deadline in Congress have introduced a level of uncertainty the company has not faced in recent memory.
