TensorWave secures $350 million as AMD invests in its competitor to Nvidia.

      TensorWave, a cloud provider operating AI data centers on AMD chips instead of Nvidia's, has secured $350 million in a Series B funding round spearheaded by AMD and hedge fund Magnetar Capital. This investment values the Las Vegas startup at $1.55 billion, which is nearly four times its estimated value of about $400 million from a year ago. Launched in 2023, TensorWave aims to provide an alternative to Nvidia, whose GPUs lead the AI infrastructure market. "We were created to restore competition to the market," said CEO Darrick Horton.

      The fresh funding will be used to expand data center capacity and acquire more chips. TensorWave has already implemented a training cluster consisting of approximately 8,000 AMD Instinct MI325X accelerators, and this funding round follows a $100 million Series A, co-led by the same investors, that took place in May 2025.

      Interestingly, AMD is financing its own customer. AMD serves as both the chip provider and a primary investor in TensorWave, utilizing its financial resources to develop a buyer for its accelerators and create a competitor to Nvidia. This strategy mirrors Nvidia's own approach, which has seen the company invest over $40 billion into AI equity this year, including $2 billion into Nebius.

      TensorWave is entering a competitive and capital-intensive market. The 'neoclouds' that offer AI computing, such as CoreWeave and Nebius, have secured multi-billion-dollar agreements but predominantly rely on Nvidia hardware. An AMD-exclusive cloud suggests that customers may be eager for an alternative source enough to consider switching.

      The challenge is one that every neocloud faces: these expansions rely on debt and equity funding based on a sustained demand for AI. AMD's support provides TensorWave with more affordable access to chips and a prominent backer, but a $1.55 billion valuation for a three-year-old infrastructure company assumes that the demand for computing power, and AMD's share in it, continues to rise.
