Cerebras Systems Raises $1.1B Series G at $8.1B Valuation (www.cerebras.ai)

Cerebras Systems announced an oversubscribed $1.1 billion Series G at an $8.1 billion post-money valuation, led by Fidelity Management & Research and Atreides with participation from Tiger Global, Valor, 1789 Capital and existing backers. The company says the capital will accelerate inventions across processor design, packaging and system-level AI supercomputers, and fund expanded U.S. manufacturing and data-center capacity to keep up with surging demand for its inference service launched in late 2024. The raise underscores growing investor confidence in specialized AI accelerators. Cerebras’ flagship Wafer Scale Engine 3 (WSE‑3) — about 56× larger than the biggest GPU — is claimed to deliver inference and training performance more than 20× faster than NVIDIA GPUs while using a fraction of the power per unit compute. That performance leadership has translated into rapid adoption (trillions of tokens served monthly) across cloud, on‑prem and partner platforms, with customers including AWS, Meta, IBM, Mistral and government labs, and #1 placement on Hugging Face (5M monthly requests). For the AI/ML community this signals stronger momentum for high-throughput, low-latency inference (critical for code generation, reasoning and agentic apps), tighter vertical integration between silicon and systems, and increased competition to GPU-dominated inference economics.
