ASML Earnings Reignite Debate Over the Sustainability of the AI Chip Boom

ASML’s latest quarterly results revived a familiar fight on Wall Street: whether the rush to build AI infrastructure is still in its growth phase or starting to stretch into something harder to sustain.

The Dutch chip-equipment maker said second-quarter revenue rose to €9.33 billion and net income reached €2.92 billion, both ahead of expectations, while it raised its 2026 sales outlook to €43 billion to €45 billion.

The company also said it plans to expand production capacity for its extreme ultraviolet, or EUV, lithography tools by about 30% over the next two years. Reuters reported that bookings for this capacity are already full through 2027, underscoring how heavily chipmakers are still spending to secure the machines used to make advanced semiconductors.

ASML’s numbers matter because the company sits near the center of the advanced chip supply chain.

Its lithography systems are used by manufacturers such as TSMC, Samsung and Intel to produce chips that power AI systems from companies including Nvidia and AMD. When ASML raises its outlook, investors often read it as a signal that the next wave of chip demand is still building.

That reading is not universal. The stronger view holds that the AI build-out is still early, with cloud companies and chipmakers continuing to place long-dated orders for equipment and capacity.

The more cautious view is that the current level of capital spending could eventually run ahead of real-world AI use, leaving the industry with excess manufacturing capacity if demand cools or monetization slows. Reuters’ commentary on the results said the announcement kept the “AI capex” cycle moving, but also highlighted the question of whether today’s spending can keep pace with the costs of next-generation tools.

There are also practical limits to how fast ASML can grow. The company said it will boost output not only of EUV machines but also of older lithography tools, including DUV systems.

Reuters reported that demand in China remains meaningful, even as export controls continue to shape what can be shipped there. ASML has said Chinese demand still accounts for a significant share of sales, while the company works within the limits of U.S.-led restrictions.

The next-generation High-NA EUV platform is another part of the debate. Reuters reported that Intel has adopted the newer technology, while TSMC has taken a more careful approach because of cost. That difference feeds a wider question among investors: whether the industry will move fast enough to justify ASML’s expansion plans, or whether the most expensive tools will take longer to scale than current AI enthusiasm suggests.

ASML’s shares rose after the announcement, reflecting investor confidence that AI-related chip demand remains strong for now. But the central argument has not gone away.

The company’s results point to a market still willing to spend heavily on the machinery behind AI, while the scale of that spending keeps raising the same uncomfortable question: how long can the boom run before supply, demand and profit expectations fall out of step?
