Cloud provider Lambda is raising up to $4 billion at a $14.5 billion pre-money valuation according to The Wall Street Journal. Coatue Management and Blackstone are leading the round. The financing marks what could be the last private round for the company before a planned 2027 initial public offering.
Lambda backlog jumps to fifty billion
A letter to investors reviewed by the Journal shows Lambda’s backlog grew from $15 billion in June to $50 billion in September. Much of this increase appears to be driven by a $35 billion commitment from one company. Anthropic signed a deal with Lambda in late August.
This massive contract means Lambda’s valuation, which climbed significantly since its 2025 funding round, could lean heavily on Anthropic’s ability to keep paying. Reliable GPU capacity remains scarce, and investors are still willing to back providers that secure large contracts with major AI labs.
Neoclouds face heavy data center costs
For neoclouds like Lambda, demand is not the main problem. The true challenge is the high cost of meeting that demand. Data center buildouts are largely funded by debt. Lambda raised an additional $1 billion in debt last week, while lenders are growing choosier about offering cash and terms.
Raising more capital now sets the tone for future initial public offering pricing. It also gives the firm access to more funds before the scrutiny of public markets arrives. The company was reportedly meant to debut this year, but pushed that timeline back amid market uncertainty.
Nvidia backed startups eye public markets
If and when Lambda goes public, it will join other Nvidia-backed neoclouds like CoreWeave and Nebius. These firms now depend on the health of their stock to fund their data center buildouts. British neocloud Nscale filed for an initial public offering last month and is expected to begin trading soon.
Lambda, Coatue, and Blackstone did not immediately respond to a request for comment regarding the funding round.
