Frankfurt's DAX 40 rose 0.4% to surpass 25,470 after a hesitant start on Tuesday, tracking gains among its regional peers. However, caution prevailed amid rising oil prices and elevated bond yields as US-Iran negotiations still appear to be at a standstill. Iranian officials have privately expressed pessimism about the possibility of reaching an agreement with Washington before the US midterm elections in November, according to Bloomberg. Infineon Technologies and AI-related Siemens Energy were among the top performers, rising 1.9% and 1.2%, respectively, following a Reuters report that Anthropic is betting on AI to transform the global economy and plans to use public investors to fund its growth.
