European AI-Related Stocks Face Sharp Sell-Off Amid Concerns Over Slower Model Development

European stocks tied to artificial intelligence infrastructure experienced a sharp decline as investors reconsidered the pace of future spending in response to calls for more cautious development. Companies like ASML and Soitec saw significant drops, with Soitec falling over 12% after previously rising on strong guidance updates. The sell-off was triggered by concerns from leading AI figures about risks associated with increasingly autonomous systems. This led investors globally to reassess their positions in companies most exposed to the AI infrastructure boom. In Europe, ASML fell nearly 5%, ASM International dropped over 8%, and Infineon lost almost 8%. The European AI trade had been built on a thesis of rapidly growing demand for computing power outpacing supply, which justified high valuations in companies providing essential equipment and materials. A slowdown in frontier model development could reduce the urgency for cloud providers to invest heavily in data centers, potentially leading to weaker long-term demand.
