Cerebras Systems, the AI chip company known for building some of the world’s largest processors, has raised $1.1 billion in an oversubscribed Series G funding round. The latest investment pushes its post-money valuation to $8.1 billion, positioning Cerebras as a formidable rival in the global AI hardware race.
The round was led by Fidelity Management & Research and Atreides Management, with participation from Tiger Global, Valor Equity Partners, and 1789 Capital. Existing investors like Altimeter, Alpha Wave, and Benchmark also joined in, signaling strong confidence in Cerebras’ growth trajectory. Barclays and Citigroup served as joint placement agents for the deal.
Expanding U.S. Manufacturing and AI Supercomputing Capacity
According to the company, the funds will be used to ramp up U.S. manufacturing, expand data center infrastructure, and accelerate its product roadmap in three key areas: AI chip design, system integration, and full-scale AI supercomputers.
Cerebras claims that its inference systems outperform traditional GPU-based setups — particularly those using NVIDIA chips — by more than an order of magnitude when running open-source models. The company’s offerings are already being used by major organizations such as Meta, AWS, IBM, Notion, Mayo Clinic, and the U.S. Department of Defense.
Micah Hill-Smith, CEO of benchmarking firm Artificial Analysis, stated, “Cerebras is consistently the fastest inference provider we’ve tested across hundreds of models.”
Betting on Inference as the Future of AI
With the rise of generative AI, efficient inference — the real-time execution of trained AI models — is increasingly seen as a bottleneck in scaling applications. Cerebras has focused on this problem since its inception, building custom systems optimized specifically for high-throughput inference workloads.
Cerebras has also gained traction on Hugging Face, where it ranks among the top inference providers, reportedly serving over 5 million requests per month.
CEO and Co-founder Andrew Feldman said the company’s focus remains on delivering cutting-edge infrastructure: “From our inception, we’ve been backed by the most knowledgeable investors in the industry. They see the historic opportunity AI presents — and they’ve chosen to back Cerebras to lead it.”
