Record rally underscores ASML’s central role in the global semiconductor and artificial intelligence boom.
ASML Holding NV (ASML) has crossed a historic threshold, becoming only the third European company to surpass $500 billion in market value, after a stronger-than-expected outlook from its largest customer, Taiwan Semiconductor Manufacturing Co.. Shares of the Dutch semiconductor equipment giant surged as much as 7.6% in Amsterdam, lifting its market capitalization to roughly €453 billion ($527 billion) and extending its year-to-date gain to 24%.
The milestone places ASML in rare company alongside European heavyweights LVMH and Novo Nordisk A/S, the only other firms on the continent to have reached this valuation level. The rally was sparked after TSMC forecast capital expenditures of up to $56 billion in 2026, exceeding market expectations and signaling sustained momentum in artificial intelligence-related spending.
ASML’s importance to the AI ecosystem cannot be overstated. As the sole manufacturer of advanced extreme ultraviolet (EUV) lithography machines, the company sits at the heart of the global semiconductor supply chain. Its technology enables TSMC to produce cutting-edge chips used in products ranging from Apple Inc.’s smartphones to Nvidia Corp.’s AI accelerators.
Market strategists note that ASML’s rise carries broader implications for Europe’s equity markets. With relatively few global-scale technology champions, gains in ASML often lift sentiment across the region, giving European investors exposure to the dominant AI investment theme.
While ASML’s valuation still pales in comparison to U.S. tech titans such as Nvidia and Alphabet Inc., both valued above $4 trillion, the achievement marks a symbolic shift. It reinforces Europe’s relevance in the AI-driven semiconductor cycle and offers early optimism for the broader tech earnings season ahead, as demand for advanced chips and equipment continues to reshape global markets.
