GPU 云 Lambda 冲刺 IPO 前最后一轮：拟募 40 亿美元、投前估值 145 亿，而订单积压从 150 亿涨到 500 亿里有 350 亿来自 Anthropic 一家

导读
据《华尔街日报》，云服务商 Lambda 正以 145 亿美元投前估值募资至多 40 亿美元，这可能它是 2027 年计划上市前的最后一轮私募融资，由 Coatue Management 与 Blackstone 领投。投资人信函显示其订单积压从 6 月的 150 亿美元增长到 9 月的 500 亿美元——看着像需求大增，但绝大部分增长来自一家公司的 350 亿美元承诺：Anthropic 在 8 月下旬与 Lambda 签了协议。也就是说，自 2025 年融资轮以来已显著上升的 Lambda 估值，可能相当程度上依赖 Anthropic 持续付费的能力。不过 GPU 产能如此稀缺，投资人显然仍愿意押注能提供的公司，尤其是有大实验室大合同的。文章进一步点出这类 neocloud 的真实难处：需求不是问题，满足需求的成本才是。数据中心建设主要靠债务融资——Lambda 上周刚刚又募得 10 亿美元——而放贷方对给谁钱、在什么条件下给正变得越来越挑剔。因此现在多募不仅为 IPO 定价定调，也让它在面对公开市场审视之前拿到更多资本。至于上市本身，该公司本应在今年挂牌，但因市场不确定性已推迟；届时它将加入其他由Nvidia投资的 neocloud 行列，如如今依赖自身股票健康程度来为数据中心建设融资的 CoreWeave 与 Nebius；英国 neocloud Nscale 上月已递交上市申请，预计很快开始交易。Lambda、Coatue 与 Blackstone 未立即回应置评请求。
推荐理由
把 neocloud 的资本结构风险量化到位：订单积压增了 350 亿但几乎全来自单一客户，债务融资收紧与 IPO 推迟这条链也交代清楚，是算力泡沫讨论中的具体样本。

Cloud provider Lambda is raising up to $4 billion at a $14.5 billion pre-money valuation, marking what could be its last private round before a planned 2027 IPO, according to The Wall Street Journal. Coatue Management and Blackstone are leading the round.
A letter to investors reviewed by the Journal shows Lambda’s backlog grew from $15 billion in June to $50 billion in September. While that might look like a hearty increase in demand, much of that increase appears to be driven by a $35 billion commitment from one company: Anthropic, which signed a deal with Lambda in late August.
That means Lambda’s valuation, which has climbed significantly since its 2025 funding round , could be leaning heavily on Anthropic’s ability to keep paying. Still, with reliable GPU capacity so scarce, investors are clearly still willing to bet on companies that provide it, especially ones with large contracts with a major AI lab.
For neoclouds like Lambda, demand isn’t so much the problem as is the cost of meeting it. Data center buildouts are largely funded by debt — of which Lambda just raised an additional $1 billion last week — and lenders are getting choosier about who they offer cash to and under what circumstances. Lambda’s decision to raise more now not only sets the tone for its IPO pricing, but also gives it access to more capital before the scrutiny of public markets arrives.
If and when Lambda does IPO — the company was reportedly meant to debut this year, but has pushed that back amid market uncertainty — it will join other Nvidia-backed neoclouds, like CoreWeave and Nebius , that now depend on the health of their stock to fund their data center buildouts. British neocloud Nscale filed for an IPO last month and is expected to begin trading soon.
Lambda, Coatue, and Blackstone did not immediately respond to a request for comment.
