Lambda

Lambda (formerly Lambda Labs) is a leading AI cloud infrastructure company headquartered in San Francisco, California, providing GPU compute for AI training, fine-tuning, and inference workloads. The company raised over $1.5 billion in its Series E round in November 2025, led by TWG Global with participation from the U.S.

Innovative Technology Fund, and is targeting a public market debut in the second half of 2026 with pre-IPO financing led by Mubadala Capital. Lambda's largest customer is NVIDIA itself, which leases back 18,000 GPUs for $1.5 billion—a unique validation of Lambda's infrastructure quality.

Additional major customers include Microsoft (a multi-billion-dollar, multi-year agreement to deploy tens of thousands of NVIDIA GPUs), Writer, Sony, Samsung, Pika Labs, and Intuitive Surgical. Lambda is known for its competitive GPU pricing: H100 SXM instances at $2.49/hour (versus $4.25/hour at CoreWeave), B200 SXM at $6.99/hour, and A100 80GB at $1.29/hour across 11+ GPU types with no egress fees.

The platform offers on-demand GPU instances, reserved clusters, and a developer-friendly API with no lock-in. Lambda serves AI researchers, startups, and enterprises that need high-throughput training compute without the complexity of hyperscaler contract negotiations.

Its focus on transparent pricing, hardware availability, and ML-optimised networking makes it particularly popular with AI research teams building foundation models and large-scale fine-tuning pipelines.
