ASML Surpasses $500 Billion Valuation on TSMC's AI Spending Plans
Shares of the Dutch chip-equipment maker hit record highs as its largest customer signals aggressive investment to meet soaring demand for artificial intelligence hardware.
ASML Holding NV, the linchpin of the global semiconductor industry, saw its market capitalization surge past $500 billion for the first time this week, propelled by blockbuster spending plans from its most important customer, Taiwan Semiconductor Manufacturing Co. (TSMC).
Shares of the Dutch technology giant rallied to a record high of $1,291.48 before settling to trade around $1,263.72. The surge underscores immense investor confidence in ASML's order book as chipmakers race to expand capacity for next-generation artificial intelligence processors.
The primary catalyst for the rally was TSMC's announcement of a massive capital expenditure forecast for 2026, projecting between $52 billion and $56 billion in spending. This represents a nearly 40% increase from its 2025 budget, signaling an unprecedented commitment to building out the infrastructure required to power the AI revolution.
ASML holds a unique and unassailable position in the semiconductor supply chain. It is the world's sole manufacturer of the extreme ultraviolet (EUV) lithography machines required to etch the microscopic circuits onto the most advanced chips. These complex machines, which can cost upwards of $200 million each, are essential for producing the cutting-edge processors designed by companies like Nvidia, Apple, and AMD, which are then manufactured by foundries like TSMC.
TSMC's aggressive expansion directly translates into multi-billion dollar orders for ASML's EUV and deep ultraviolet (DUV) systems. The move is seen as a direct response to the unrelenting demand for data center hardware and AI-enabled devices, a trend that analysts have dubbed the "AI Infrastructure Supercycle." The broader semiconductor equipment sector has rallied on the news, with global wafer fab equipment spending now projected to hit a record $145 billion in 2026.
According to its latest financial data, ASML has a market capitalization hovering near $493 billion, holding most of its recent gains. The company's stock has been on a powerful upward trend, reflecting its critical role and strong financial performance, including a return on equity of over 53%.
While the demand outlook appears exceptionally strong, the company's fortunes are closely tied to the capital expenditure cycles of a few key customers. Furthermore, the entire semiconductor industry continues to navigate geopolitical risks, particularly surrounding US-led restrictions on technology exports to China. However, the sheer force of the AI-driven demand, underscored by TSMC’s latest profit jump and investment plans, has firmly positioned ASML as a primary beneficiary of the next wave of technological expansion.
