Lambda Seeks Up to $4B Before Its Planned 2027 IPO

GPU cloud provider Lambda is lining up one more large private round before it tries the public markets. According to The Wall Street Journal, the company is raising up to $4 billion at a pre-money valuation of $14.5 billion. Coatue Management and Blackstone are leading the deal.

This could be Lambda's last private raise before a planned IPO in 2027. The company was reportedly supposed to list this year but delayed those plans because of market uncertainty.

A backlog that more than tripled

An investor letter seen by the Journal shows Lambda's backlog rising from $15 billion in June to $50 billion in September. Backlog is the value of contracted work a company has not yet delivered. On its face, that jump suggests strong demand.

The details tell a narrower story. About $35 billion of the increase seems to come from a single customer: Anthropic, which signed an agreement with Lambda in late August. Without that contract, the backlog would have grown far less.

That concentration matters for how investors should read the valuation. Lambda's price has risen sharply since its 2025 funding round. A large part of that rise may now depend on Anthropic continuing to pay its bills over the life of the contract. Readers who followed the leaked Anthropic IPO filing will recognize the tension: the lab is growing quickly, but it is also spending heavily.

Investors appear willing to accept that risk. Reliable GPU capacity remains hard to find, and backers are still betting on companies that can supply it, especially those with large contracts from a major AI lab.

Demand is easy, financing is not

Lambda belongs to a group often called "neoclouds": providers that focus mainly on renting out GPU computing for AI work, rather than offering the broad menu of services that traditional cloud giants sell.

For these companies, finding customers is not the main challenge. Paying for the infrastructure is. Data center construction is largely financed with debt. Lambda added another $1 billion in debt just last week. At the same time, lenders are becoming more selective about who they fund and on what terms.

Raising equity now does two things for Lambda. It helps set expectations for how its shares might be priced at IPO. And it gives the company more capital before it faces the closer scrutiny that comes with being a public company.

Joining a growing public cohort

If Lambda does go public, it will sit next to other Nvidia-backed neoclouds such as CoreWeave and Nebius. Those companies now rely on the health of their share prices to keep funding new data centers. British neocloud Nscale filed for an IPO last month and is expected to start trading soon.

Lambda, Coatue and Blackstone did not immediately respond to TechCrunch's request for comment.

The Bigger Picture

The Lambda numbers show a pattern that runs through the AI infrastructure market: headline growth often rests on a small number of very large customers. A backlog of $50 billion sounds like broad demand, but when roughly $35 billion traces back to one lab, the company's fortunes become closely tied to that lab's finances. This suggests investors are pricing neoclouds partly as a bet on the AI labs that sign their contracts.

The financing side deserves equal attention. Debt has paid for much of the data center buildout so far, and if lenders keep tightening terms, equity rounds and public listings become more important. That puts stock performance at the center of the model, as it already is for CoreWeave and Nebius. It is also a reminder of the wider pressures on data center expansion, from cost to local opposition to new facilities.

What to watch next: how Nscale trades once it lists, whether Lambda's 2027 timeline holds, and whether the company can widen its customer base so that a single contract carries less of the weight.
