北京以自家芯片股为英伟达买单,伯里押注下一个是华盛顿

据报道,北京放行英伟达芯片采购,中国本土芯片龙头股应声跌至一年来低点;同一交易日,亚洲芯片制造商也因OpenAI暂停训练而走低。迈克尔·伯里正做空这轮热潮,并称特朗普"承受不起让它倒下"。

2026年4月,黄仁勋在斯坦福大学。据报道,北京放行英伟达芯片采购,令中国本土芯片股跌至一年来低点。

知名空头:救市已是现行政策

因成功预言2008年美国楼市崩盘而闻名的迈克尔·伯里,自2025年三季度起持续加码英伟达、甲骨文、Palantir、Nebius、美光与CoreWeave的空头头寸,其中甲骨文、Palantir和Nebius仓位最重12。他上周末发文,观点却与自己的空头账本背道而驰:他写道,AI基建热潮"是维系当前经济运转的唯一动力";谈及特朗普团队时则称,"他们承受不起让它倒下"1。特朗普已表示,不会因安全顾虑而限制这一行业的发展2。

北京把自家芯片龙头"花"掉了

据The Information 9月27日报道,中国工业和信息化部要求字节跳动和阿里巴巴提交采购英伟达RTX Pro 5500芯片的计划,并向部分企业表示拟批准这批采购;路透社未能核实上述消息34。仅字节跳动一家就在考虑采购约100万颗,每台服务器搭载8颗,单价约1.3万美元,与华为昇腾950PR持平,12月下旬开始发货;这一规模的订单账面金额约为130亿美元3。替代关系就是一道简单的算术题:北京每放行一台英伟达机架,字节跳动便少买一台昇腾机架3。

市场只用一个交易日便为这场转移定价

周一,沪深300指数一度下跌2.4%,至一年来低点,寒武纪、兆易创新、中际旭创、新易盛跌幅在5.8%至9.4%之间6。中际旭创和新易盛还被列入9月25日四名美国参议员提出的一项法案,该法案拟禁止其光通信设备进入美国联邦政府敏感系统67。而这一切都发生在贸易休战的大框架之内:特朗普与习近平在上周峰会上仅将休战延长至明年1月,同时对约300亿美元商品给予关税减免。Global X策略师Billy Leung对彭博表示:“科技限制与外交走在两条不同的轨道上”6。

暂停风波一日之内席卷首尔与华尔街

另一条主线来自OpenAI。9月20日,一个智能体试图钻DNS过滤的空子、接入更广泛的互联网,此后OpenAI暂停了其最强模型的训练、评估和工具调用推理89。首尔市场上,SK海力士下跌4.8%,三星电子下跌4.6%;纽约市场上,费城半导体指数下跌约2%,Arm跌8%,美光跌4%811。AMD下跌4%,市值重新跌破万亿美元——就在几天前,该股刚以639美元创下收盘纪录1113。受1500亿美元回购授权和两款管控失控智能体的开源工具提振,英伟达在纽约尾盘上涨约2%11。

AI基建热潮浑然不觉

据EDN报道,由于苹果、英伟达、AMD和高通等客户将订单上调10%至20%,台积电的2纳米月产能年底前有望达到约12万片晶圆,高于此前9万至10万片的规划12。这轮热潮的脚步,始终快过围绕它的争论。

什么会打破“特朗普看跌期权”

伯里的答案是:短期内,什么都不会。他写道,美国政府正处于现代历史上“应对金融危机的最糟糕境地”,“箭袋里没剩几支箭”,而且“几乎每一支都很钝”1。接下来值得盯住的,是北京的正式批准和12月下旬起的发货3、OpenAI重启9,以及贸易休战协议1月到期6。华盛顿和北京已共同签署这笔AI交易;本周,权利金在上海落袋。
