Lambda Seeks $4 Billion at $14.5 Billion Pre-Money, and Anthropic Is 70% of Its $50 Billion Backlog

Lambda, the Nvidia-backed GPU cloud operator, is raising up to $4 billion at a $14.5 billion pre-money valuation, with Coatue Management and Blackstone leading, according to a Wall Street Journal report relayed by TechCrunch. Lambda, Coatue and Blackstone did not immediately respond to requests for comment. This is a report of a round being raised, not a closed one, and "up to" is the phrase carrying the weight.

The detail that matters sits in the investor letter the Journal reviewed. Lambda's backlog of unfilled orders grew from $15 billion in June to $50 billion in September, AI Weekly reports.

One customer is 70 percent of the backlog

TechCrunch attributes much of the $35 billion increase to a single contract: Anthropic's $35 billion commitment, signed in late August. Against a $50 billion backlog, that is 70 percent in one name.

The Anthropic contract was itself reported before Lambda said anything. Digit reported on Sept. 1 that Anthropic had agreed a $35 billion compute deal with Lambda, using a data centre being developed by Hut 8 in Nueces County, Texas, where the Journal said Nvidia would hold the lease. Anthropic declined to comment, and Nvidia, Lambda and Hut 8 did not immediately respond.

Digit adds that Anthropic also agreed a $45 billion deal with Nscale in West Virginia and a $50 billion deal with Fluidstack. Those are reported figures from a single outlet and are unconfirmed by the companies.

Reading $14.5 billion pre-money

Pre-money and post-money are different numbers here. If Lambda raises the full $4 billion, the post-money valuation is $18.5 billion, and the new investors would own about 21.6 percent. If it raises less, the stake and the post-money figure shrink together.

Measure	Figure
Pre-money valuation	$14.5 billion
Maximum raise	$4 billion
Post-money at full raise	$18.5 billion
Backlog, Sept. 2026	$50 billion

The backlog is more than three times the pre-money valuation, which sounds generous until the shape is considered: backlog is contracted future revenue, not revenue already earned. Lambda's revenue was not disclosed in TechCrunch's report. Digit said in September that Lambda was seeking up to $3 billion at a valuation of $12 billion or more, so the ask grew by $1 billion and the reported pre-money by $2.5 billion in about five weeks.

Debt does the building

The data centre buildouts are largely debt-funded, TechCrunch says, and Lambda raised an additional $1 billion in senior secured, fixed-rate financing. Lenders are becoming more selective, the article adds. A creditor lending against a contract wants to know the counterparty can pay, which returns the question to Anthropic's ability to keep paying a bill of this size.

Debt is also how others are paying for scale: Waymo closed its first debt deal, $5 billion at 5.25 points over benchmark, while Mecka AI's $60 million round shows how much smaller the equity cheques are further down the stack. Lambda's comparables are CoreWeave and Nebius, which TechCrunch says rely on their stock performance to fund buildouts, and Nscale, which has filed for an IPO.

What would confirm it

Lambda plans to go public in 2027, down from an earlier 2026 target pushed back amid market uncertainty, and TechCrunch says this could be its last private round. A closing announcement naming the amount actually raised, or an S-1 stating the backlog and its customer concentration, would settle what the investor letter only implies.
