作者以霍华德·马克斯的泡沫框架解读美股调整与AI资本开支回报
作者转述霍华德·马克斯的观点称,当前市场尚未达到真正意义上的泡沫状态,因为市场持续讨论泡沫风险,投资者并未对风险“浑然不觉”;他同时认为投资者对进一步上涨存在错失恐惧,鲁莽行为信号则较为混杂。

我被推荐,和看到太多聊AI风险的,说实话,这些风险我都认同,但是少有把风险和机遇放一起分析最后做出结论的,只聊风险并不会显得自己有多聪明,对未来需求的判断才是最难的,起码华尔街那些人23年GPT到现在,预测英伟达的一年后的盈利预期从来没有对过。 https://t.co/b9Nm961XwB 引用 @TJ_Research:美股的泡沫分为估值泡沫和盈利泡沫 估值现在根本没有泡沫,无论静态还是动态。 盈利泡沫需要向前看,在你听到别人聊泡沫时,记得多问一句,你看到未来的盈利风险在哪里?对建立自己的观点会有帮助的
挺有意思,周末很多人聊的都是黑色星期一但早上美股开盘看起来并没那么慌不择路。“黑天鹅或者黑色星期一不会在每个业务爱好者在线上不停谈论它的时候发生。但会发生你睡着觉然后醒来发现白费20%” https://t.co/nRd4b6jjEe https://t.co/UmXU2Q4cu4 引用 @qinbafrank:过去七个交易日内美股的这一波抛售是如何发生的?10月8日前后开始,市场对AI高增长叙事和资本开支可持续性的质疑逐步升温,多个事件叠加形成共振: 1)10月8日左右:OpenAI营收口径差引发第一波抛售 OpenAI向投资者披露,截至9月底年化营收约500亿美元,低于市场此前流传的约7
新云的资本结构和融资方式会影响其风险情景范围,激进融资若依赖再融资并承担全部现货风险,在利率和现货价格走势不利时,再融资可能变得灾难性。一个年化回报率为15%的两年期项目,MOIC约为1.2倍;用两年期分期偿还的15%债务融资,贷方回报倍数也是1.2倍,而用15%的两年期债券融资,回报倍数为1.3倍。分析需明确资产与负债的久期及其中隐含的再投资机会假设。
过去七个交易日,美股因AI变现与资本开支回报受质疑、通胀和油价担忧升温而集中抛售。OpenAI年化营收口径差、Anthropic营收增速放缓及AI基础设施公司融资压力,加上CPI、PPI和布伦特原油走高,加重市场对利率与现金流的担忧。作者认为这属于高速增长叙事下的市场波动,后续关注云巨头财报能否显示收入增长和现金回报。
Nebius的投资者不能既要又要:一边声称享受杠杆化AI基础设施扩张的上行空间,一边因为Nebius有软件栈就无视共同风险。 Nebius有Aether、Soperator和Token Factory。CoreWeave有SUNK、Mission Control和Weights & Biases。AWS有SageMaker和Bedrock。编排、托管推理和开发者工具在这些提供商之间都是有竞争力的产品。它们的质量很重要,但“Nebius在建云、CoreWeave是GPU数据中心OEM”这种区分站不住脚。 你可以更喜欢Nebius的软件、客户结构或融资方式,而且它的合作伙伴出资模式可能降低资本

JPM’s chart puts global AI compute demand at ~450 GW in 2030 and ~530 GW in 2031. Translating that into capital and revenue shows aggressive these assumptions seem to be. At an illustrative $50B per fully equipped GW (low-end by the way as costs are moving up), supplying 530 GW 引用 @pequityresearch
发文者表示,若 Josh 引述的数据属实,他大体认同其判断:按 YE26 口径,约 1000 亿美元收入对应约 5 GW 算力,其中仅约 1.25 GW 服务付费客户。按付费服务算,每 GW 收入约 800 亿美元,按整体混合口径约 200 亿美元;引用内容称,Anthropic 85% 的毛利率和超过 40% 的算力利润率意味着 70%—75% 的算力用于研发。

Thought it'd be helpful to frame this in economic output terms relative to history: Anthropic staff's survey answers imply US real GDP growth of ~18.6% in the 12 months to January 2030 (17.1% in the model's log terms). In the BEA annual record back to 1929, comparable growth https://t.co/j1RJcEaOKC
Fair distinction on the terminology and it's not fair for me to blend them. My broader point is that the investment case still assumes today’s revenue persists and grows so you're still making the same implicit bet. In reality, subscribers can churn, API customers can reduce 引用 @ramez:@ShanuMat

市场追逐算力短缺,推动资本承诺加速,但竞争和商品化压缩产品利润率,利率与地缘政治冲击也可能增加融资难度。投入依据是当下的稀缺经济学,回报却取决于多年后的现金流;算力和基础设施可能结构性供给不足,建设融资的资本复杂性也可能过度扩张。
