Alphabet (GOOG 1.10%) (GOOGL 1.06%) told inv ...

如果把时间拨回一年前，华尔街几乎形成了共识：只要是AI相关的资本支出，规模越大、投入 越激进，未来的护城河就越深。彼时的逻辑很简单——算力决定上限，模型决定胜负，而现金 流只是暂时性的牺牲。 但进入2026年，这套逻辑正在被市场亲手拆解。 亚马逊正式跌入熊市区间，微软成为Mag7中最早确认熊市的一员，Meta距离20%的技术性熊 市只剩一步之遥；与此同时，Alphabet的跌幅明显受控，英伟达则被推到了所有交易的"风暴 眼"。 这并不是一轮普通的科技股回调，而是一次 AI投资逻辑的阶段性结算 ： 市场第一次开始系统 性地追问——这些前所未有的AI资本支出，究竟能不能转化为可验证的回报。 七大巨头不再同涨同跌，正是这个问题被摆上台面的直接结果。 分化的起点：当AI资本 支出开始侵蚀现金流安全垫 真正的分水岭：不是投不投AI， 而是AI能否被"内部消化" 表面上看，最近一轮抛售似乎是情绪主导，但真正让市场产生分歧的，是 AI支出对财务结构的 冲击已经变得不可忽视 。 【如需和我们交流可扫码添加进社群】 以亚马逊为例。2026年高达2000亿美元的资本支出计划，在两年前会被视为"云计算+AI长期 护城河"的加码，如 ...
