Lambda, supported by Nvidia, plans to raise up to $4 billion ahead of IPO
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.

ABAB AI Insight
Lambda was founded in 2012 by twins Stephen and Michael Balaban, initially selling graphics processor workstations for researchers, later transitioning to renting cloud computing power. In February 2025, Nvidia entered with a $480 million Series D round, and in November, TWG Capital led a $1.5 billion financing at a post-money valuation of $5.9 billion. In May 2026, the founders were shifted from CEO to CTO, with Michel Combes, who has experience with Sprint and Altice, brought in as CEO, and public company financial and board configurations were adjusted in preparation for the IPO rather than product milestones.
The capital path is "equity anchoring, debt expansion, chip factory binding." Coatue and Blackstone are buying the last tranche of equity before the IPO, while the two secured loans totaling about $1.9 billion in August and October are the funds for purchasing graphics processors. Nvidia supplies both products and holds shares, while Anthropic uses the $35 billion commitment to pre-book future usage in backlog. The funds are not going towards applications but rather converting scarce cards into rentable racks.
A comparable case is CoreWeave: similarly reliant on Nvidia, similarly thickening backlog through a single large customer, and similarly prioritizing debt before equity, with the stock price post-IPO directly determining whether the next round of data centers can commence operations. Nebius is pursuing a strategy of restructuring before going public to expand production capacity in Europe and the U.S. Lambda is currently at the stage of "controlling capacity, not yet accepting public pricing," with orders signed according to the scale of cloud giants, while equity is still sold at private placement discounts.
This is a restructuring of the industry chain, not merely a valuation increase. Training and inference are being separated into independent new cloud layers, with pricing power temporarily resting with those who can deliver graphics processors on time. The mechanism is: laboratories need to lock in multi-year capacity, chip manufacturers need to lock in multi-year shipments, and private equity needs to enter before public market discounts. A single customer taking up all of the backlog increase for three months indicates that growth at this level is still contract-concentrated, not demand-dispersed.
