European shares rise as Siemens Energy forecast lifts AI optimism; inflation concerns persist

European shares opened higher on Wednesday and traded close to record levels, supported by upbeat forecasts from Siemens Energy and US-based artificial intelligence infrastructure company CoreWeave, which helped ease concerns about the outlook for AI-related investments. However, persistent inflation worries limited broader market gains, Reuters reported.

The pan-European STOXX 600 index rose 0.7% to 662.83 points by 0807 GMT, bringing it within touching distance of record highs reached in August, Reuters reported.
