美股夜盘，中国科技巨头百度（BIDU）股价大涨5.01%，引发市场关注。这一涨幅很可能与公司最新的人工智能（AI）战略及中概股整体走强有关。
根据最新消息，百度正全力投入大模型领域，并在近期发布了多项重要举措。百度副总裁陈一凡在百度联盟大会上表示，公司正在用户产品与商业系统等方面进行自我革新，以应对AI带来的新机遇。百度还联手华为、荣耀、OPPO等主流手机厂商发布了"百看计划"，通过AI重构内容、体验和服务，提升用户搜索体验。这些举措显示出百度在AI领域的持续创新和领先地位，可能增强了投资者对公司未来发展的信心。
此外，当日美股夜盘中概股普遍走高，如再鼎医药涨超11%，小鹏汽车涨超3%，理想汽车、哔哩哔哩、京东等均有不同程度上涨。这一整体趋势也可能带动了百度股价的上涨。投资者对中国科技股的renewed兴趣，加之百度在AI领域的积极布局，共同推动了公司股价的显著上涨。
