On July 15, according to BIT (bit.com) market data, Apple’s stock rose nearly 3% during Wednesday's trading session, reaching a peak of $325.4, setting a new all-time high.

Alibaba's stock also saw a strong performance, rising over 6.6%, while Baidu's stock increased by more than 3.3%, reflecting growing market expectations for the integration of domestic AI ecosystems.
