Lambda Labs secures $500 million in debt financing to expand GPU cloud services and data center capacity.

Lambda Labs, an operator of a GPU-infused cloud, has secured a $500 million loan to fund the expansion of its accelerators-as-a-service offering. The deal, backed by Macquarie Group and Industrial Development Funding, will support the deployment of "tens of thousands" of Nvidia's fastest accelerators, which will serve as collateral for the loan.

GPUs of the sort Lambda employs cost $30,000 to $40,000 each and are in incredibly short supply. Lambda has worked on GPU systems for over a decade and has offered cloud services for the past six years. The "asset-based" nature of the deal will allow Lambda to rent out the accelerators to customers without requiring long-term contracts, a strategy that capitalizes on demand from smaller AI startups hesitant to commit to lengthy agreements.

This approach contrasts with traditional cloud pricing models. For example, on-demand pricing for Amazon's P5 instances, which include eight H100 accelerators, is $98.32 an hour, or about $12.29 per GPU. However, customers who commit to a three-year lease can reduce that to $43.16 per hour. Lambda lists a comparable configuration at $27.92 per hour.

The $500 million in debt financing comes in addition to the $320 million in Series C funding Lambda secured in February. That earlier funding was designated for additional Nvidia H100, H200, and GH200 superchip capacity, along with an upgrade to its InfiniBand network. Nvidia's H200, due out in Q2, is particularly notable for its larger HBM3e memory capacity of 141GB, compared to 80GB on the H100, and faster memory bandwidth, allowing customers to run larger models on fewer GPUs.

Lambda is far from the only GPU cloud provider seeking to capitalize on AI demand. Competitors like CoreWeave and Voltage Park have emerged as bit barns offering datacenters with 10,000 or more GPUs available for rent at prices below those of larger cloud providers. Many of these deployments have been funded by massive debt; CoreWeave, for instance, expanded its datacenter footprint last summer thanks to a $2.3 billion loan from Magnetar Capital and Blackstore.
