European semiconductor and electrical equipment stocks climbed sharply as investor confidence grew around the expanding artificial intelligence (AI) boom. Companies seen as key players in AI infrastructure benefited from strong earnings and optimistic forecasts, mirroring a powerful rally in U.S. chip stocks. The surge reflects increasing global demand for advanced chips and supporting technologies as AI adoption accelerates.
Dutch chip equipment maker ASM International jumped to a record high after projecting stronger-than-expected second-quarter sales, driven by robust AI demand. Meanwhile, Swiss engineering giant ABB also raised its full-year outlook, citing increased demand from data centres and electrification businesses despite geopolitical uncertainties.
Other major European players, including ASML, Infineon, and STMicroelectronics, recorded solid gains. Analysts believe that years of weak investment are now giving way to an AI-led growth cycle, with spending expected to accelerate from 2026 as companies invest heavily in digital infrastructure, energy, and supply chain resilience.
