- Lambda is reportedly raising up to $4B at a $14.5B pre-money valuation.
- Blackstone and Coatue lead what could be its last private round before a 2027 IPO.
- Its backlog rose $35B between June and September, the size of a reported Anthropic deal.
Through its Series E in November 2025, Lambda had raised more than $2.3 billion in equity since twin brothers Stephen and Michael Balaban founded it in 2012. It is now reportedly asking investors for up to $4 billion at once.
The Nvidia-backed company is raising at a $14.5 billion pre-money valuation, the Wall Street Journal reported, citing people familiar with the matter. Pre-money means the price before the new cash goes in.
If Lambda raises the full amount, Tech Funding News calculates, the post-money valuation would be $18.5 billion. Blackstone and Coatue Management are leading the round, which would be Lambda’s last private financing before an initial public offering planned for 2027, depending on execution and market conditions, according to a letter to its limited partners that the Journal reviewed.
A valuation that keeps climbing
Lambda is a neocloud: a specialist cloud provider that rents out graphics processing units, the chips used to train and run AI models. The California-based company started by selling GPU workstations and servers to machine learning developers and moved into cloud services around 2018. It runs 15 data centres in the US, according to its website.
Its price has moved fast. The $480 million Series D in February 2025, co-led by Andra Capital and SGW with Nvidia among the new investors, reportedly valued Lambda at $2.5 billion. Lambda did not disclose a valuation for the Series E, led by TWG Global; outside estimates run from about $4 billion to $5.9 billion.
In August, Bloomberg reported that Lambda was in talks to raise up to $3 billion at $12 billion or more. The new figure is about 20% above that and roughly 2.5 times the highest Series E estimate.
How much of the $50B backlog is Anthropic?
The letter shows Lambda’s backlog of unfilled orders rising from $15 billion in June to $50 billion in September. It reportedly runs six years and covers about 350 megawatts at a data centre that Hut 8 is building in Nueces County, Texas. Hut 8 will not lease the site to Lambda directly. Nvidia is the tenant and supplies the chips, and Lambda pays it an undisclosed sum for access, Bisnow reported. None of the companies had commented when the deal was reported, so the $35 billion figure rests on sources, not an announcement.
That leaves Nvidia as Lambda’s investor, its chip supplier, and the leaseholder of the Texas site. It has also reportedly signed a $1.5 billion deal to lease its own chips back from Lambda.
A backlog is not revenue. Nscale, which filed for a US IPO, reports about $103 billion in total contract value but says only about $2.6 billion of it, roughly 2.5%, is active today. About 25,000 of its 461,000 active and contracted GPUs are running. Contracted demand still needs data centres, chips, power, and financing before it earns anything.
The neocloud race
Lambda’s lead investors know the sector. Coatue led CoreWeave’s $1.1 billion Series C in May 2024, a round that reportedly valued it at $19 billion, and Blackstone Credit & Insurance anchored its $8.5 billion financing facility in March 2026. CoreWeave, listed since March 2025, then signed a $6 billion cloud deal with Jane Street in April, alongside a $1 billion equity investment.
Crusoe announced the initial close of a $3.9 billion Series F on September 17 at a $30.9 billion post-money valuation, co-led by Atreides Management, Mubadala Capital, and Valor Equity Partners, with Nvidia and Founders Fund among the backers. Its Series E in October 2025 valued it at just over $10 billion.
Nscale was valued at $14.6 billion in its $2 billion Series C in March, almost exactly where Lambda’s round is priced. Reports now put its IPO target atup to $35 billion. It also announced $3.36 billion in convertible notes on September 25, led by Third Point, with $2.36 billion at closing and $1 billion from Nvidia due in mid-November.
Gartner expects worldwide spending on AI-optimised infrastructure as a service , meaning rented computing power, to rise 96% to $42 billion in 2026 and reach $66 billion in 2027. Inference, the cost of running models after they are trained, is forecast to overtake training this year at $23.3 billion against $19 billion. The demand starts with labs that can still raise at record prices; OpenAI is reportedly in talks to raise $30 billion at a fixed $1.4 trillion valuation.
The $14.5 billion price assumes Lambda can turn a $50 billion backlog into delivered capacity and cash. Nscale’s filing shows how long that can take: about 2.5% of its contracted value is active today.
When Lambda files its own IPO paperwork, the number to find is how much of the $50 billion is Anthropic, and how much of it is earning revenue now.
