European stock indices, including the STOXX 600, advanced on Tuesday, propelled by a rally in technology shares. The gains were primarily driven by investor optimism in the artificial intelligence sector.
The surge followed a report that AI developer Anthropic is considering a public offering that could value it at more than $2 trillion. This news boosted sentiment for the entire AI supply chain, benefiting European semiconductor companies that are key suppliers for AI infrastructure.
Firms such as ASML Holding, STMicroelectronics, and Infineon Technologies were among the top performers. However, broader market gains were kept in check by concerns over rising crude oil prices and elevated bond yields, which tempered overall investor enthusiasm.
