Cerebras Systems

About Cerebras Systems

Cerebras Systems is an AI infrastructure company founded in 2016 and headquartered in Sunnyvale, California.

The company designs and manufactures the world’s largest AI chip — the Wafer Scale Engine (WSE-3) — which is 57× larger than the Nvidia H100 and delivers up to 10× faster AI training and inference performance.

Cerebras generated $290.3 million in revenue in 2025, representing 76% year-over-year growth, and reported $87.9 million in net income, a rare achievement for an AI hardware company at the time of its IPO.

The company’s flagship customer is OpenAI, which has committed over $20 billion for 750MW of Cerebras compute capacity through 2028. Personal backers of the OpenAI deal include Sam Altman, Greg Brockman, and Ilya Sutskever.

The IPO Opportunity

The Cerebras IPO is the largest technology IPO of 2026 to date, raising $4.8 billion at a valuation of approximately $34.4 billion.

The offering was upsized by 40%, from $3.5 billion to $4.8 billion, driven by institutional demand that exceeded available shares by 20 times.

CBRS will begin trading on the NASDAQ Global Select Market on May 14, 2026.

Key Information

What is CBRS?

CBRS is the NASDAQ ticker for Cerebras Systems, Inc., an AI hardware and infrastructure company.

Unlike traditional semiconductor businesses, Cerebras has designed a single chip the size of an entire silicon wafer (the WSE-3), enabling massively parallel AI computation at speeds no GPU cluster can match.

The company operates both on-premise (CS-3 systems) and cloud-based (Cerebras Cloud) compute services, with live customers including AWS, Meta Llama API, Perplexity, and Mistral.

Technology: WSE-3 vs Nvidia H100

The Cerebras WSE-3 chip represents a fundamentally different approach to AI compute:

Key Customer: OpenAI

OpenAI has committed over $20 billion for 750MW of Cerebras compute capacity through 2028.

Cerebras won this business from Nvidia, providing fast inference for an OpenAI model that writes code.

Personal backers of the deal include Sam Altman, Greg Brockman, and Ilya Sutskever, OpenAI’s most prominent founders.

Additional cloud partners include Amazon Web Services (via Bedrock), Meta Llama API, Perplexity, and Mistral.

Founder: Andrew Feldman, Co-Founder & CEO

Andrew Feldman holds approximately 10.3 million shares post-IPO (valued at approximately $1.28 billion) and is selling zero shares in the offering, a strong signal of founder conviction.

Prior to Cerebras, Feldman co-founded SeaMicro, a low-power microserver company, which was acquired by AMD in 2012 for $334 million. He subsequently served as Corporate VP at AMD Data Center Server Solutions.

Under his leadership, Cerebras achieved the first Wafer-Scale Engine (WSE-1) in 2019, a milestone the industry had considered impossible for 75 years, and secured the $20B+ OpenAI partnership in 2026.
