Cerebras Systems has closed an oversubscribed $1.1 billion Series G funding round, achieving an $8.1 billion post-money valuation. The AI infrastructure company, known for building the world’s fastest AI processors, attracted significant interest from both new and existing investors.

Fidelity Management & Research Company and Atreides Management led the investment round. Tiger Global, Valor Equity Partners, and 1789 Capital participated with substantial contributions, while existing backers Altimeter, Alpha Wave, and Benchmark also joined the funding.

AI Infrastructure Market Drives Unprecedented Demand

The artificial intelligence sector has seen explosive growth, particularly in inference services where speed directly impacts user experience and operational costs. Cerebras has positioned itself at the center of this transformation by delivering processing speeds that consistently outperform traditional GPU solutions.

Real-time AI applications have created new performance requirements. Code generation, reasoning systems, and agentic workflows now demand processing capabilities that can handle complex tasks without delays. This shift has made inference speed a competitive advantage rather than just a technical specification.

Scaling Technology and Manufacturing Operations

The new funding will support Cerebras’ continued innovation in AI processor design and system architecture. The company plans to advance its Wafer Scale Engine technology, which currently delivers processing capabilities 56 times larger than traditional GPUs while using significantly less power per computation.

Cerebras will also expand its U.S. manufacturing capacity to meet growing demand for its hardware solutions. The company operates its own cloud infrastructure and provides on-premises solutions for enterprise customers, requiring substantial data center investments to support this dual approach.

Company Background and Technical Innovation

Founded by Andrew Feldman and his team, Cerebras Systems has focused on solving fundamental bottlenecks in AI computing. The company’s flagship product, the Wafer Scale Engine 3 (WSE-3), represents a different approach to processor design that prioritizes raw computational throughput over traditional metrics.

“From our inception we have been backed by the most knowledgeable investors in the industry. They have seen the historic opportunity that is AI and have chosen to invest in Cerebras. We are proud to expand our consortium of best-in-world investors.”

The company has built its reputation on consistent performance leadership. Since launching its inference service in late 2024, Cerebras has maintained processing speeds more than 20 times faster than Nvidia GPUs across both open-source and proprietary models.

Growing Customer Base and Market Recognition

Cerebras serves trillions of tokens monthly across various deployment models. The company’s client roster includes major technology firms like AWS, Meta, IBM, and Mistral, as well as enterprise customers such as GlaxoSmithKline and Mayo Clinic. Government agencies, including the U.S. Department of Energy and Department of Defense, have also adopted Cerebras solutions.

Individual developers have embraced the platform as well. On Hugging Face, the primary AI development hub, Cerebras ranks as the top inference provider with over 5 million monthly requests. This developer adoption indicates growing recognition of the platform’s technical advantages.

“Since our founding, we have tested every AI inference provider across hundreds of models. Cerebras is consistently the fastest.”

Investment Partnership and Financial Advisory

Citigroup and Barclays Capital served as joint placement agents for the transaction. The involvement of established financial institutions reflects the maturity and scale of Cerebras’ funding requirements as the company prepares for its next growth phase.

The investor consortium includes both technology-focused funds and traditional institutional investors, suggesting broad confidence in the AI infrastructure market’s long-term prospects.
