TensorWave raises $350M Series B to scale AMD-only AI cloud

TensorWave, a Las Vegas-based AI cloud provider built entirely on AMD Instinct GPUs, has closed a $350 million Series B funding round to expand its AMD-powered AI infrastructure. The round was co-led by Magnetar and AMD Ventures, with continued participation from Maverick Silicon, Nexus Venture Partners, and Western Frontier, and values the company at a $1.55 billion post-money valuation. TensorWave announced the financing on June 10, 2026, positioning the company as one of the best-funded challengers to Nvidia-centric AI cloud offerings.

The fresh capital will be used to grow TensorWave’s global AMD GPU clusters, increase data center capacity, and support larger, memory-intensive AI workloads such as large model training and inference. The company operates an AI and high-performance computing cloud that runs on AMD Instinct accelerators and the ROCm software stack, offering enterprises an open alternative to Nvidia lock-in while helping AMD deepen its ecosystem around AI workloads. This Series B follows a roughly $43 million seed round in October 2024 and a $100 million Series A in May 2025, bringing TensorWave’s total funding to around $493 million and representing a near quadrupling of its valuation from about $400 million at the time of the Series A.

By tying large-scale AI compute capacity directly to AMD hardware, TensorWave’s growth provides AI developers and enterprises with additional supply of non-Nvidia accelerators at scale, potentially easing GPU scarcity and diversifying infrastructure choices across the market. For AMD, co-leading the round further aligns chip sales with real-world AI cloud usage, while for investors the $1.55 billion valuation reflects strong conviction that an AMD-focused cloud can gain share as organizations seek cost-effective, high-performance alternatives to the dominant Nvidia stack.
