TensorWave raises $350M Series B at $1.55B, deploys AMD-powered AI alternative to NVIDIA

TensorWave, a Las Vegas-based AI cloud platform, raised $350 million in Series B funding co-led by Magnetar Capital and AMD Ventures at a $1.55 billion post-money valuation. The round included continued participation from Maverick Silicon, Nexus Venture Partners, and Western Frontier. TensorWave specializes exclusively in AMD Instinct GPU infrastructure for high-performance, memory-intensive AI workloads, positioning itself as an open-ecosystem alternative to capacity-constrained, vertically integrated providers like NVIDIA.

The company now operates one of the largest AMD-based AI training clusters in North America with 8,192 AMD Instinct MI325X GPUs online and is preparing larger MI355X deployments across multiple new data center regions. TensorWave has secured more than 2 gigawatts of long-term data center capacity and counts customers including Fireworks AI and Luma AI. The company's total funding has reached approximately $493 million since its seed round in October 2024, with the Series A ($100M) valuation increasing nearly 4x.

For enterprises evaluating GPU infrastructure, TensorWave's AMD-exclusive focus addresses NVIDIA supply constraints and vendor lock-in concerns, though AMD's software ecosystem remains less mature than CUDA. The capital will fund continued cluster expansion, MI355X deployments, hiring (the company plans to double headcount from 160 to 300–400 in the next 12 months), and Las Vegas headquarters expansion. As demand for production-scale AI compute grows, AMD alternatives like TensorWave are gaining credibility with major builders seeking diversified supply chains.
