ASML Stock Hits Record High 2026: Valuation Tops 500 Billion Euros

The world’s AI hunger is fueling a Dutch giant. ASML just hit record highs as it cements its position as the sole gatekeeper of high-end chipmaking. Following a stellar earnings report from TSMC, ASML shares surged, pushing the company's valuation past the 500 billion euro mark on January 16, 2026.

TSMC Earnings Fuel ASML Stock Record High 2026 Momentum

Since TSMC released its financial results, ASML shares have climbed about 7%. The company is now the third European firm ever to cross the half-trillion euro valuation. So far in 2026, the stock has rallied 25%. Morgan Stanley recently issued a bull case suggesting a 70% upside, potentially reaching 2,000 euros per share if tech demand continues to spike.

Bank of America noted on Friday that TSMC's capital expenditure guidance significantly exceeded expectations. This creates a ripple effect for ASML because their EUV (extreme ultraviolet) tools are critical for manufacturing the next generation of AI processors.

Supply Chain Dynamics and Macro Tailwinds

The broader semiconductor landscape is also providing a boost. Memory prices are forecast to jump 40-50% in the first quarter of 2026. JPMorgan points out that Samsung is likely to increase equipment orders significantly to utilize its available clean room capacity. Additionally, the U.S. decision to cap tariffs on Taiwanese tech at 15% has stabilized the outlook for ASML’s largest customers.
