TensorWave has raised $350 million in Series B funding at a $1.55 billion valuation, a major raise for the cloud computing startup. The Las Vegas, Nevada company announced the round on June 10, 2026.

The financing was co-led by Magnetar and AMD Ventures, with continued participation from Maverick Silicon, Nexus Venture Partners and Western Frontier. The valuation roughly tripled the company’s implied worth from just over a year earlier, and the round brings TensorWave’s total funding to approximately $493 million since it was founded in 2023.

What sets TensorWave apart is its hardware choice. The company runs its AI infrastructure exclusively on AMD’s GPUs rather than the chips from market leader Nvidia. That decision puts TensorWave in an unusual position, betting that AMD’s accelerators can meet the demands of large-scale AI work and that customers will value an alternative to the dominant supplier. The participation of AMD Ventures in the round reinforces that alignment.

The new capital will fund the expansion of TensorWave’s global AI infrastructure footprint, including the deployment of next-generation AMD Instinct MI355X GPU clusters. Those clusters are aimed at memory-intensive workloads such as large language model training, high-throughput inference and generative AI applications, the kinds of tasks driving surging demand for compute.

TensorWave has also locked in capacity to support that growth, securing more than two gigawatts of long-term data center capacity to serve enterprise, research and AI-native customers. Data center capacity has become a real constraint in the AI buildout, so reserving it at that scale is a strategic move. With a fresh $350 million and a clear hardware bet, TensorWave is positioning itself as a sizable independent player in AI cloud infrastructure.
