AI的故事，正在从"软件吞噬世界"，演变为"硬件被世界卡住"。 在极度撕裂的美国政治环境中，能让极左翼参议员伯尼·桑德斯（Bernie Sanders）和极右翼州长罗恩·德桑蒂斯（Ron DeSantis）站在同一阵线的议题几乎不 存在——除了 "遏制数据中心" 。 这不仅是华盛顿的政治奇观，更是华尔街面临的冷酷"物理修正"。当硅谷巨头们挥舞着比"阿波罗登月计划"还要昂贵的支票簿，试图通过堆砌算力延续AI繁荣 时，他们撞上了 由政治和物理电网极限共同筑就的高墙。 纽约州立法者也已经提出法案，计划对新建数据中心的建设和运营许可实施至少三年的暂停。纽约至少是第六个考虑暂停新数据中心建设的州。 总之，从佛罗里达州的社区抗议，到德克萨斯州电网的监管急刹车，一个被市场忽视的风险正在急剧升温： 如果物理电网接不上、政治环境不答应，那原本计 入估值模型的数千亿美元资本开支，可能根本"花不出去"。 当桑德斯与德桑蒂斯"合谋" 桑德斯和德桑蒂斯在绝大多数议题上势同水火，但在数据中心激增的问题上，他们达成了罕见的共识： 必须踩下刹车。 这种跨党派"联合"的敌意，源于美国民众对"AI副作用"的切肤之痛。全美各地，数据中心24小时不 ...

AI时代，快人一步~ 随着AI基础设施建设的军备竞赛进入"深水区"，一个令投资者不安的转折点已然浮现：为了支撑AI算力需求，亚马逊、谷歌和Meta正面临自由现金流被耗尽甚 至透支的风险。 根据摩根大通2026年2月5日发布的研究报告，美国四大云巨头——亚马逊、谷歌、Meta和微软，2026年总资本支出预计将达到 6450亿美元 ，同比激增 56%，新增支出将达到惊人的2300亿美元。 如果说谷歌还只是在"疯狂花钱"，那么 亚马逊 则堪称"透支未来"。 2026年，亚马逊的资本支出指引约为 2000亿美元 （同比增长52%）。但问题的核心在于，亚马逊赚回来的现金已经盖不住支出了——据标普全球市场分析师 预测，亚马逊2026年的运营现金流（OCF）约为 1780亿美元 。 对于投资者而言，2026年，或将是紧盯科技巨头资产负债表的一年。 谷歌的97%增速与亚马逊的"现金赤字" 在这场基建狂潮中， 谷歌 的投入非常激进。 2026年，谷歌的资本支出指引已上调至 1750亿至1850亿美元 ，同比增速高达 97% ，其资金正疯狂涌向服务器和技术基础设施。 这意味 ...

2026年初，科技分析师惊恐地盯着交易终端，一场软件股的血腥抛售正席卷整个华尔街，对冲基金精准狙击AI冲击下的脆弱环节，收获了一场做空盛宴。 短短一个多月，美股软件行业总市值蒸发 1万亿美元，而在这场崩塌中，对冲基金通过做空软件股已斩获 240亿美元 的利润 金融分析公司S3 Partners的数据显示，对冲基金正加大对软件股的做空力度，成为今年以来该领域惨烈抛售的主要推手之一 这些对冲基金并未选择普遍做空科技板块，而是精确瞄准了那些为客户提供基础自动化服务的公司——这类服务被认为极易被新兴的人工智能工具所取代 这一数据背后是整个行业面临的生存危机。DA Davidson分析师吉尔·卢里亚直言不讳地指出："对冲基金目前对软件板块全是净做空。" 这股做空浪潮与AI技术进步密不可分，市场正日益担忧AI技术将彻底颠覆传统软件商业模式 而投资者们似乎集体认为，软件行业正经历一场深刻的 "结构性变革" ，这可能导致更多的并购活动，包括大型公司对小型企业的收购 对冲基金的做空策略具有极强的针对性。据两家主要对冲基金的消息人士透露，目前做空火力集中于那些业务模式容易被新兴AI工具取代的公司，尤其是 提供基础自动化服务的企业 ...

在人工智能浪潮的推动下，美国四大科技巨头正开启一场本世纪以来规模空前的资本竞赛。最新预测显示，Alphabet、亚马逊、Meta Platforms和微软在二零 二六年的合计资本支出有望达到约六千五百亿美元，较前一年大幅增长约百分之六十。这笔令人瞠目的资金，将如洪流般涌入新建数据中心、AI芯片、网 络设备及备用发电机等一长串硬件设施之中。 紧随其后，Alphabet抛出了高达一千八百五十亿美元的年度资本支出预测，让投资者感到不安。亚马逊的预估则更为惊人，其二零二六年资本支出计划可能 触及两千亿美元大关，消息公布后其市值应声下挫。这一系列数字不仅反映了企业对未来的巨额押注，也凸显出行业ai基础设施竞赛的白热化。 这场由少数 科技巨头主导的投资狂潮，正对更广泛的经济层面产生涟漪效应。规模庞大、耗电极高的数据中心在全美各地加速建设，已在局部地区导致能源供应紧张， 并引发了对电价上升的普遍担忧。同时，由于这些科技企业在整体经济活动中的占比日益增大，其庞大的资本开支可能会扭曲宏观经济数据的解读，成为影 响经济决策的新变量。 据凯德北京投资基金管理有限公司分析师分析，全球数据中心建设浪潮正在这股力量的推动下再次提速。从芯 ...
