事件：亚马逊 CEO Andy Jassy 在其年度股东信中透露，亚马逊正考虑将其自研的 AI 处理器出售给第三方，这将加剧与 Nvidia 和 AMD 的竞争。与此同时，Jamie Dimon 预计到 2026 年，排名前五的超大规模云服务提供商将把 AI 支出增加 60% 以上，达到 7250 亿美元。微软正在大力投资 AI 模型、芯片和基础设施，而 Meta 则向关键领导者授予股票期权以留住 AI 人才。Arm 推出了其首款 AI CPU，Meta 和 OpenAI 为首批客户。

市场影响：AI 军备竞赛正在推动半导体制造业竞争加剧，亚马逊可能进入该市场。科技巨头的这一轮支出热潮将使 AI 基础设施公司受益，但可能会挤压小型软件公司。微软激进的 AI 战略可能导致“主权 AI 陷阱”，而 Meta 大量的 AI 支出引发了对其执行能力和回报的担忧。Arm 的新型 AI CPU 可能会颠覆市场，已有知名客户加入。

后续关注：投资者应密切关注微软截至 2026 财年第三季度（4 月 25 日）的财报，以评估 AI 支出是否超过了回报。此外，关注 Palantir 在其 2023 年第一季度财报（5 月 2 日）中报告的政府和商业部门的增长势头。最后，关注 Alphabet 在其 2023 年第一季度财报（4 月 26 日）中关于其视频流媒体部门的更新，因为它在用户参与度和收入方面与 Netflix 竞争。
