TensorWave Raises $350M in Series B Funding at $1.55B Valuation

The round also saw participation from Maverick Silicon, Nexus Venture Partners, and Western Frontier.

The company plans to use the new funding to expand its global AI infrastructure, including the deployment of next-generation AMD Instinct™ MI355X GPU clusters. These systems are designed to support demanding AI workloads such as large language model training, high-volume inference, and generative AI applications.

As global demand for AI computing power continues to grow, TensorWave offers an alternative to traditional GPU providers through its open, high performance infrastructure. This approach gives organizations greater access to the computing resources needed for advanced AI-workloads.

The company is already being used by emerging AI firms such as Fireworks AI and Luma AI, which rely on TensorWave's AMD-based infrastructure to run large-scale generative AI applications and production AI systems.

Since its Series A funding round in May 2025, TensorWave has grown rapidly. 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 to deploy larger MI355X clusters across multiple new data center locations in North America.

TensorWave has also secured more than 2 gigawatts of long-term data center capacity to support increasing demand from enterprise, research, and AI-focused customers. To support this expansion, TensorWave is continuing to invest in its headquarters in Las Vegas and plans to hire across several areas, including engineering, infrastructure, operations, sales, and customer success.

“The most ambitious AI builders need infrastructure that can keep pace with them right now, at a scale very few providers can deliver,” said Piotr Tomasik, President, and Co-Founder of TensorWave. “The continued trust of exceptional investors validates our approach: reliable, scalable compute purpose-built for the most demanding production workloads, backed by 24/7 support and a footprint designed to serve customers globally. This funding accelerates our ability to meet that demand while building a world class team within the Las Vegas startup community.”

“The race to build AI infrastructure has created urgent demand for providers who can deliver at speed without sacrificing reliability," said Ross Laser, Co-Founder and President of Magnetar. "TensorWave's partnership with AMD and its disciplined execution make it exactly that – and we believe it is positioned to become one of the most important compute providers for AMD-based AI workloads.”

“The next phase of AI will be defined by who can access enough compute to move from experimentation to production,” said Darrick Horton, CEO and Co-Founder of TensorWave. “As models grow larger and workloads become more demanding, enterprises need infrastructure with the memory capacity, performance, and flexibility to scale without being locked into a single ecosystem. This investment allows TensorWave to bring AMD Instinct MI355X GPU deployments to more customers and continue building the open, AMD-powered foundation for production AI.”
