GPU云“裁判”加冕Nebius铂金级 “大空头”伯里加码做空
ClusterMAX 3.0将Nebius送入GPU云服务最高梯队,323家受评云厂商中仅19家摘得奖牌;而就在几天前,罗斯柴尔德Redburn刚抛出卖出评级,CoreWeave也发行了37亿美元可转债。评级认证的是算力集群,信贷市场却在给“算力房东”重新定价。

账单10月1日起上调
2026年10月1日起,Nebius将三个月内第二次上调按需价格:部分英伟达GPU涨价17%至21%,部分纯CPU实例涨价25%,内存类产品涨价约41%1。而更贵的账单,恰好落在刚被行业技术“裁判”送上最高梯队的这家云厂商身上。

奖牌与卖出评级落在同一周
9月23日发布的ClusterMAX 3.0将Nebius升入铂金级(Platinum),与CoreWeave并列——自该基准2025年3月推出以来,这是首次有厂商与CoreWeave同处最高梯队23。这份报告基于对200多家终端用户的访谈,在跟踪的323家云厂商中仅向19家颁出奖牌2。Crusoe降至青铜级(Bronze);Fluidstack被标为“不可用”(Unavailable)2。
同一周,华尔街站到了交易的另一头。9月21日,罗斯柴尔德Redburn对Nebius首次覆盖即给予卖出评级,目标价84美元,较周一开盘价低62%;该行认为,信贷市场已开始为风险定价,而AI股票大体上忽视了这些风险4。一天后,迈克尔·伯里披露,已增持Nebius空头头寸,且“规模不小”5。ClusterMAX称CoreWeave背负350亿美元债务2;这家公司以2.875%的票面利率将发行规模上调至37亿美元的可转债定价,相比之下,优先票据票息为8.5%至9.75%67。
卖方市场,谁来买单?
对此,ClusterMAX把话说得很直白:规模不及前沿水平的实验室,要面对高额预付款和更差的价格;OpenAI和Anthropic正把基础设施转为自建;Nebius对一年期合约要求的预付款比例最高可达100%2。
市场将这次涨价解读为定价权的体现:股价盘前一度上涨11%,最终涨幅回落至约2%;两轮调价过后,B300的费率累计上涨约56%8。Nebius第二季度录得营收5.823亿美元,同比增长454%,靠的是四份平均金额均超过10亿美元的合同14。同一组数字也撑起了空头的论据:5吉瓦的扩建计划尚有约2000亿美元待融资,而账上现金只有80亿美元,空头持仓占流通股的比例已接近18%49。

“裁判”评的是集群,不是资产负债表
ClusterMAX已公开的测试内容,没有一项为违约风险定价;融资分析放在另一条独立的研究条线上2。这位“裁判”同时还兼卖哨子:它呼吁买家、云厂商、保险公司和债务合作伙伴,把自家付费的技术评估写入验收测试和服务等级协议(SLA)审查;而刚刚把Crusoe降至青铜级(Bronze)、把Fluidstack标记为“不可用”(Unavailable)的,正是这同一位“裁判”,这些放贷方承销的债券中,就有Fluidstack的2。多头拿已签约的需求作答:CoreWeave在手订单1042亿美元,Nebius账上现金80亿美元64。集群是铂金级(Platinum),资产负债表则是一场赌局。
见分晓的日子是10月1日。如果涨价能够站稳,又不把中端市场的实验室推向白银级(Silver)的对手,这份溢价就是凭实力挣来的;若不然,空头便等来了他们想要的底部。
