Cerebras Systems Leads the Way for the Next Era of AI Infrastructure Game

Cerebras Systems, developer of the fastest AI infrastructure in the industry, led by Andrew Feldman, Jean-Philippe Fricker, Michael James, Gary Lauterbach, Sean Lie, and others, has secured $1.1 billion Series G funding round at $8.1 billion post-money valuation led by Fidelity Management & Research Company and Atreides Management, with participation from Tiger Global, Valor Equity Partners, and 1789 Capital, as well as existing investors Altimeter, Alpha Wave, and Benchmark.

Cerebras will use the new funding to advance innovations in AI processor design, packaging, system architecture, and supercomputing. The company also plans to scale its U.S. manufacturing and data center capacity to meet surging demand for its products and services.

Since launching its inference service in late 2024, Cerebras has seen extraordinary growth. Over the past year, it has consistently held the performance crown, achieving speeds more than 20× faster than Nvidia GPUs on both open- and closed-source models.

Cerebras’ performance edge has driven massive demand. Real-time use cases such as code generation, reasoning, and agentic tasks highlight the cost of being slow, drawing customers to Cerebras’ cloud, on-premises, and partner platforms. Today, the company processes trillions of tokens per month.

In 2025, AI leaders, including AWS, Meta, IBM, Mistral, Cognition, AlphaSense, and Notion, along with enterprises and government agencies like GlaxoSmithKline, Mayo Clinic, the U.S. Departments of Energy and Defense, have adopted Cerebras. Individual developers on Hugging Face also rank Cerebras as the #1 inference provider, handling over 5 million monthly requests.

Citigroup and Barclays Capital served as joint placement agents for the transaction.
