How One Microsoft Contract Flipped the GPU Model.

Lambda sells GPU compute two ways: on-demand cloud rental at published hourly rates and large reserved-capacity contracts with hyperscalers and enterprises. The growth inflection came from the second category — most visibly a multibillion-dollar deal with Microsoft signed before the November 2025 Series E, which turned Lambda from a spot-market GPU vendor into a contracted capacity provider.

The capital cycle explains the pace. Lambda raised over $1.5B from TWG Global and USIT in November 2025 to build what it calls 'superintelligence cloud' infrastructure, bringing total funding past $2 billion. Revenue roughly tripled from the ~$425M run rate of late 2024 to a ~$1.5B expectation for 2026, and the company is reportedly negotiating a pre-IPO round of up to $3B at a $12B-plus valuation.

Revenue Mix

  • Reserved enterprise capacityMultibillion-dollar multi-year contracts, anchored by the Microsoft deal.
  • On-demand GPU cloudHourly rental of H100/B200-class instances, the original core business.
  • On-premises systemsLambda workstations and GPU servers sold to labs and enterprises.

FAQ

Lambda Revenue, Answered.

What Is Lambda's ARR in 2026?
Lambda's 2026 revenue expectation is roughly $1.5 billion, per figures reported to investors. That follows a ~$425M revenue run rate in December 2024 and $500M by May 2025. The figure is an expectation, not a company-disclosed audited run rate.
How Fast Did Lambda Grow?
Cloud GPU rental revenue grew nearly 100% year over year as of May 2025, when the company reported a $500M run rate. From there, contracted deals — above all the multibillion-dollar Microsoft agreement — carry the trajectory toward ~$1.5B in 2026.
How Much Has Lambda Raised?
Over $2 billion. The $480M Series D in February 2025 included NVIDIA; the $1.5B+ Series E in November 2025 was led by TWG Global and USIT. A pre-IPO round of up to ~$3B at a $12B+ valuation has been reported as in talks.
Who Are Lambda's Biggest Customers?
The most consequential publicly reported deal is with Microsoft, signed ahead of the Series E and described as worth billions. Beyond that, Lambda's customer base spans AI labs, enterprises and researchers renting cloud GPUs or buying on-premises systems.
What Does Lambda Actually Sell?
GPU compute. On-demand cloud instances at hourly rates, reserved enterprise capacity under multi-year contracts, and Lambda-branded GPU workstations and servers for customers who want the hardware on premises.
