为给人工智能（AI）的巨大投入提供资金，科技公司正以前所未有的规模涌入债券市场。 据《华尔街日报》11月23日报道，自今年9月初以来，包括亚马逊、Alphabet、Meta和甲骨文在内的所谓"AI超大规模企业"（AI hyperscalers）已发 行近900亿美元的投资级债券。 根据Dealogic的数据，这一规模超过了这些公司此前40个月的发行总额。与此同时，评级较低的AI数据中心开发商也发行了超过70亿美元的投机 级债券。 目前，其评级仅比投机级高出两档，其债券收益率已高于几乎所有投资级科技同行。研究公司CreditSights的高级分析师Jordan Chalfin指出，甲骨 文未来三年可能还需发行约650亿美元的债券，维持投资级评级对其至关重要，因为投机级市场的融资规模远不足以支持其需求。 投机级债券的警示信号，风险正在外溢至股市 在风险更高的投机级市场，警示信号更为明确。作为少数拥有次投资级债券的主要AI云服务提供商，CoreWeave的处境颇具代表性。 据报道，该公司7月份发行的2031年到期债券，近期交易价格已跌至面值的92美分，对应的收益率高达约11%，与评级最低的CCC级债券平均水平 相当 ...

人工智能（AI）的快速扩张，将科技行业推向一场规模前所未有的资本投入与基础设施建设竞赛。 然而，随着资金持续涌入、数据中心规划不断加码，技术产业正在遭遇现实世界的物理瓶颈。从电力供应到关键设备产能，从土地审批 到投资回报预期，这些因素共同构成了人工智能产业的"地基"，也决定了未来数年AI能否维持当下的狂飙态势。 评估全球AI投资风险的核心在于两个基本问题：一是全球是否具备支撑庞大AI基础设施的物理与能源条件；二是投入巨额资金建设出来 的AI产品和服务，是否能够在未来产生足够收入，以回收这些高达数万亿美元的投入。来自金融机构与行业企业的最新数据，为观察这 一趋势提供了重要视角。 科技巨头与AI初创公司在资本支出上的步伐并未放缓。近期财报显示，多家企业在过去数个季度持续加码投资，一些企业的资本开支增 幅创下历史新高。高盛资深分析师吉姆·施耐德（Jim Schneider）指出，当前用于建设数据中心的资本几乎处于无限供给状态。芯片、服 务器、散热系统、变压器、燃气轮机、电力线路乃至发电设备，这些构成AI超级计算机的关键部件正在经历一轮前所未有的采购潮。各 家公司在争抢产能，它们试图为未来的AI模型与服务争取计算优势 ...

AI狂热要见顶了吗？ 美国银行策略师Michael Hartnett在其最新的报告中提出了一个大胆的预测：进入2026年的"最佳交易"将是做空那些 在AI领域投入巨资的"超大规模云服务商"（hyperscaler）的公司债券。他认为，由AI引发的债务压力将成为这些科 技巨头新的"阿喀琉斯之踵"。 Hartnett的观点基于一个核心判断：支撑AI热潮的宽松金融环境正迎来拐点。尽管过去12个月全球央行进行了167次 降息，但预计未来一年降息次数将锐减至81次。这种流动性势头的减弱，意味着信贷利差的最低点已经过去，而这 对于需要巨额融资的行业来说并非好消息。 尽管信贷市场的裂痕已经开始显现，Hartnett认为这并不意味着股市的狂欢将立即结束。他预计，在包括"美联储看 跌期权"、"特朗普看跌期权"在内的多重支撑下，资产配置者在进入2026年时仍将普遍持有股票多头头寸。 Hartnett为市场划定了一个关键的时间节点：明年5月15日。这一天是新任美联储主席获得任命的时间。他判断，在 此之前，市场不太可能出现由银行股或信贷利差引发的重大"风险规避"信号。换言之，做多股市的交易在明年5月 前似乎依然安全。 AI的债务风险 ...
