## Summary

Wafer-scale AI chip maker with WSE-3 (4T transistors). Founded 2015, $23B valuation, ~$2.9B total funding. $10B+ deal with OpenAI. IPO expected Q2 2026 (CBRS).

## Company Overview

Cerebras Systems is an AI hardware company founded in 2015 by Andrew Feldman, Gary Lauterbach, Michael James, Sean Lie, and Jean-Philippe Fricker, headquartered in Los Altos, California. The company designs the world's largest AI processor, the Wafer-Scale Engine (WSE-3), containing 4 trillion transistors and 900,000 AI-optimized cores on a single wafer-sized chip with 44GB on-chip SRAM.

Cerebras competes directly with NVIDIA, offering a fundamentally different architecture using one massive chip instead of GPU clusters. It sells hardware and cloud-based AI compute. A landmark multi-year deal with OpenAI valued at over $10 billion will supply AI compute infrastructure. Revenue grew 535% in 2024 from $78.7 million.

Cerebras has raised approximately $2.9 billion including a $1B Series H in February 2026 led by Tiger Global at a $23 billion valuation. The company confidentially refiled for IPO in February 2026 targeting a Nasdaq listing under ticker CBRS in Q2 2026.

## Frequently Asked Questions

### What is Cerebras Systems?
An AI hardware company building the world's largest AI processor, the WSE-3, with 4 trillion transistors on a single wafer-sized chip.

### How does Cerebras differ from NVIDIA?
Cerebras uses a single massive chip with 44GB on-chip SRAM, eliminating inter-chip communication bottlenecks that GPU clusters face.

### When will Cerebras go public?
Confidentially refiled February 2026, expected Nasdaq listing under CBRS in Q2 2026.

### What is Cerebras' deal with OpenAI?
A multi-year compute agreement valued at $10B+ announced January 2026.

### How much funding has Cerebras raised?
~$2.9 billion total, including a $1B Series H in February 2026 at a $23B valuation led by Tiger Global.

### What is the WSE-3 and how big is it?
The Wafer Scale Engine 3 (WSE-3) is Cerebras's flagship AI processor, spanning an entire silicon wafer at 46,225 mm² — roughly 57 times larger than the largest GPU die. It contains 4 trillion transistors and 44 GB of on-chip SRAM, enabling models with hundreds of billions of parameters to run without inter-chip communication.

### Who are Cerebras's main customers?
Cerebras serves national labs, research universities, sovereign AI programs, and enterprises. Notable deployments include partnerships with G42 (UAE national AI), Mayo Clinic, Argonne National Laboratory, and several defense agencies. The OpenAI compute agreement announced in January 2026 is its largest commercial deal.

### Can developers access Cerebras chips without buying hardware?
Yes, through Cerebras Inference — a cloud API offering ultra-fast inference on Llama models and other open-source LLMs. Pricing is competitive with GPU cloud providers and the service emphasizes low latency, making it suitable for real-time applications that GPU clouds cannot match.
