Is Lambda public? Can you buy its stock?
No. Lambda is a private company, so its shares don't trade on any stock exchange and it has no ticker symbol.
Lambda has been preparing a listing since 2025. In September 2025 The Information reported that it hired Morgan Stanley, J.P. Morgan and Citi for an IPO (Sacra). In January 2026 The Information reported a plan to list in the second half of 2026 (Forge Global).
That debut was pushed back amid market uncertainty, TechCrunch reported in October 2026. A letter to its limited partners, reviewed by the Wall Street Journal, says Lambda aims to go public in 2027. That depends on execution and market conditions. No IPO filing has been reported.
Its shares are held privately by its investors, among them TWG Global, USIT and Nvidia. No stakes have been disclosed. This page reports facts and gives no investment advice.
Valuation, round by round
Lambda's last confirmed valuation was $1.5B in February 2024, and the round in talks in October 2026 would value it at $14.5B before new money.
| Date | Valued at | Raised | Led by | Source |
|---|---|---|---|---|
| Oct 2026 | $14.5B | In talks | Coatue Management and Blackstone | TechCrunch |
| Aug 2026 | $12B | In talks | — | Tech Funding News |
| Nov 2025 | — | $1.5B+ | TWG Global | Lambda's blog |
| Feb 2024 | $1.5B | $320M | US Innovative Technology Fund (USIT) | Lambda's blog |
Sacra puts the November 2025 Series E at $5.9B post-money and a 2025 Series D at $2.5B, but no primary report confirms either. Neither the August nor the October 2026 talks have been reported closed.
Revenue
Sacra estimates Lambda's yearly run rate rose from $505M in September 2025 to $760M at the end of 2025. Reports in August 2026 expected more than $1.5B in revenue for 2026.
A run rate is a month's revenue times twelve and isn't audited revenue. An estimate from The Information, cited by Forge, puts revenue at over $520 million for the twelve months to September 2025.
How Lambda makes money
Lambda rents NVIDIA GPUs by the hour and in reserved clusters. Cloud GPU rental brings in the bulk of its revenue, and legacy hardware sales are a shrinking share, Sacra says.
Sacra puts its gross margin in the first half of 2025 at about 50%, or roughly 61% without non-cloud lines. Those are Sacra's estimates.

- B200 on demand. An NVIDIA HGX B200 instance is listed at $7.69 per GPU per hour, from the same date. Lambda's pricing page
- Reserved clusters. 1-Click Clusters run from 16 to 2,000+ B200 or H100 GPUs, with reserved capacity priced through its sales team. Lambda's pricing page
- Long contracts. Anthropic agreed to spend about $41.3 billion with Lambda over terms into 2034. Fees accrue only as capacity is delivered and accepted. SEC (Anthropic S-1/A)
Products
Lambda began as Lambda Labs. Its first product, in 2013, was a facial recognition API for Google Glass, which Sacra says drove more than 5 million API calls a month. In 2017 it moved into selling AI hardware, including a GPU laptop called the TensorBook.
Today it sells GPU cloud capacity. In November 2026 its website moved to a new address, lambda.com.

- Instances. Self-serve HGX B200 and H100 instances that spin up in minutes. Lambda's website
Customers
Lambda reports serving 200,000+ AI developers and teams, according to Sacra.
A letter to investors showed its backlog grew from $15 billion in June to $50 billion in September 2026 (TechCrunch). Much of that came from one customer, Anthropic.
