Lambda, a cloud computing company supported by Nvidia, plans to raise up to $4 billion in its final round of private funding before going public, with a pre-money valuation of $14.5 billion. The round is led by Coatue Management and Blackstone, with a target IPO in 2027, depending on execution and market conditions.

A letter to limited partners shows that the backlog of unfulfilled orders increased from $15 billion in June to $50 billion in September, with nearly all of the increase coming from a $35 billion computing commitment signed with Anthropic in late August. The company operates 15 data centers in the U.S. using only Nvidia chips and racks, and plans to expand its computing power to gigawatt scale by 2030.

This round values the company at $14.5 billion pre-money, and approximately $18.5 billion post-money if fully raised. A $1.5 billion financing led by TWG Capital in November 2025 had a post-money valuation of only $5.9 billion, while Nvidia participated in a $480 million Series D round in February 2025. The valuation increase is highly tied to single customer orders.

The company has completed two debt transactions this year: a $926 million term loan B closed on August 27, and about $1 billion in delayed draw term loans closed on October 1, used for purchasing graphics processors and data center construction. Equity financing and debt are running in parallel, with expansion primarily relying on external capital rather than operating cash flow.

In May, co-founder Stephen Balaban stepped down as CEO to become CTO, with Michel Combes taking over as CEO, and former AT&T executives John Donovan and Charles Fisher joining as board member and CFO, respectively. The company has not commented on financing reports, and this round has not yet closed, with size and terms still subject to change.

The buyers are growth and private equity funds positioning themselves ahead of the public market, while the seller is the equity issued by Lambda; the transaction is driven by the surge in backlog orders and the 2027 IPO timeline. Funds are directed towards graphics processor procurement and data center capital expenditures, with Nvidia securing chip sales and Anthropic locking in training and inference capacity. The pressure point lies in customer concentration: if the $35 billion commitment is delayed in payment or reduced, both valuation and debt coverage will be repriced.

Peer paths have been made public. CoreWeave is set to go public by the end of March 2025, Nscale announced its prospectus in late September, and Firmus is also advancing towards an IPO. The common constraint for new cloud vendors is: orders are visible, but expansion requires debt to buy chips.
