Groq, the AI inference chip startup that’s been turning heads with its Language Processing Unit technology, is raising $650 million to fund its next phase of growth.

For context, Groq closed a $640 million Series D in August 2024 at a $2.8 billion valuation, with BlackRock funds leading the charge. Less than a year later, the company is back at the fundraising table, this time at a valuation that could reach roughly $6 billion, more than doubling its worth in under twelve months.

What Groq actually does, and why investors keep writing checks

Groq’s LPU architecture is purpose-built for inference workloads. Founded in 2016 by Jonathan Ross, the former lead of Google’s Tensor Processing Unit division, Groq has positioned itself as a direct alternative to Nvidia’s GPU-centric approach.

The new capital is earmarked for expanding GroqCloud inference capacity and developing the company’s next-generation LPU technology. Disruptive Capital is reportedly leading the round, with participation from BlackRock and Neuberger Berman among others.
