Best GPU Neoclouds 2026: CoreWeave, Nebius, Lambda, Crusoe, and Groq Ranked by Published Pricing and Contracted Power

The ‘neocloud’ label now covers five companies with very different business models. CoreWeave and Nebius are public companies that publish quarterly results and file reports with the SEC (CoreWeave on Form 10-Q, Nebius as a foreign private issuer on Form 6-K). Lambda and Crusoe are private and heading toward IPOs. Groq has run GroqCloud on its LPU architecture since 2024; after licensing that technology to NVIDIA in December 2025, the independent Groq refocused entirely on inference-cloud infrastructure. This article compares them on what actually matters to a buyer: published pricing, deployed and contracted power, hardware roadmap, contract structure, and independent quality ratings. CoreWeave is the only Platinum-rated GPU cloud in SemiAnalysis ClusterMAX 2.0 and commands premium list pricing on H100, H200, and B200. Nebius is the only provider here publishing B300 on-demand pricing; Lambda publishes the lowest B200 on-demand rate. Lambda still publishes the cheapest on-demand B200 ($6.69/GPU-hr) but has no spot tier. Crusoe is the only provider here with AMD MI300X/MI355X on its rate card. Groq is now an NVIDIA Cloud Partner and plans to add NVIDIA GPU capacity alongside its LPU inference cloud. $6.16node price ÷ GPUs $3.85HGX, on-demand $3.99SXM, 8x instance $3.90HGX, on-demand +454% YoY · ARR…
