Cerebras Systems has filed for an initial public offering as the AI boom accelerates.
On Apr. 17, the AI chip maker submitted its registration statement with the U.S. Securities and Exchange Commission. The company plans to list its Class A common stock on the Nasdaq under the ticker symbol CBRS.
Founded in 2015 and based in California, Cerebras builds specialized processors for artificial intelligence. Its main product is the Wafer-Scale Engine 3, known as the WSE-3.
This chip is the largest commercial AI processor in the world. It is 58 times larger than NVIDIA Corp‘s (NASDAQ: NVDA) (ETR: NVD) B200 GPU and offers much more on-chip memory and bandwidth.
These features allow faster AI training and inference with lower latency and power use. Cerebras sells complete CS-3 systems for customers to run on their own sites. It also provides cloud-based inference services.
The firm’s revenue grew to US$510 million in 2025. That marked a 76 per cent jump from US$290 million in 2024. Most revenue still comes from hardware sales, but cloud services are expanding.
A company spokesperson indicated the IPO is planned for mid-May 2026, which would mean shares could begin trading around that time, subject to SEC review, market conditions and completion of the roadshow. No exact trading start date has been confirmed yet, and the process could shift depending on how quickly amendments are filed and approved.

Recent deals fuel growth and market position
This IPO move builds directly on recent high-profile partnerships that have strengthened Cerebras in the AI sector.
Early in 2026, the company signed a major agreement with OpenAI. The deal is valued at more than US$20 billion over three years and includes up to 750 megawatts of computing capacity. It covers model co-development and fast inference work. The agreement also grants OpenAI warrants for a minority equity stake.
OpenAI reportedly shifted some of its fast-inference tasks from NVIDIA to Cerebras. This refers to the high-speed generation of outputs from a trained AI model. These are optimized for minimal latency and high tokens-per-second so responses feel instant and natural in real-time applications like chatbots or coding assistants.
In March 2026, Cerebras also reached a multi-year partnership with Amazon Web Services. AWS will deploy Cerebras chips in its data centres, making it the first major cloud provider to offer the technology at global scale.
Beyond OpenAI and AWS, Cerebras works with clients such as Meta Platforms Inc (NASDAQ: META) (FRA: FB2A) for its Llama API, Perplexity, Mistral, Hugging Face, G42 and MBZUAI. Cerebras has been positioning itself as a credible rival to NVIDIA in the competitive AI chip market. Its technology delivers strong performance advantages, including up to 15 times faster inference on some open-source models while using less power, according to the company.

Skepticism persists over long-term success
Despite the progress, many observers remain skeptical about Cerebras’ ability to succeed as a public company.
The S-1 filing reveals heavy reliance on a small number of customers. In 2025, about 86 per cent of revenue came from two related UAE entities: MBZUAI at 62 per cent and G42 at 24 per cent.
Although the OpenAI and AWS deals promise more diversification, questions linger about whether growth is truly scalable or still tied to a handful of large buyers. Critics also highlight equity warrants given to customers like OpenAI, which dilute future ownership while subsidizing deals.
“Cerebras going public, I read their S1, not buying this one,” commented Shadi Copty, a former artificial intelligence leader at Meta. “The ‘profit’ in 2025 is a mirage: net Income of US$237.8 million; US$363.3 million of that is a one-time, non-cash paper gain from cancelling a massive preferred stock contract liability (!)”
Other concerns include manufacturing yields for wafer-scale chips, supply-chain risks and the challenge of competing against NVIDIA’s dominant ecosystem and software advantages.
This filing marks Cerebras’ second attempt at going public after withdrawing an earlier one. As the company seeks a valuation potentially in the tens of billions on roughly US$500 million in trailing revenue, investors will watch closely to see if its tech can drive sustainable growth.
lol wait a second. OpenAI gave Cerebras a billion dollar loan?? Also most of its revenue comes from two customers, a UAE based university and a UAE based company called G42. https://t.co/EeY9w0po9z pic.twitter.com/0MpKvWcY0t
