Cerebras moves toward IPO after strong investor demand
AI chipmaker Cerebras Systems said it plans to sell 28 million shares at $115 to $125 apiece in its IPO, aiming to raise about $3.5 billion. If priced at the top of the range, the offering would value the company at $26.6 billion and could be the largest tech IPO of 2026 so far.
Cerebras Systems is finally moving its long-awaited IPO toward the finish line. On Monday, the AI chipmaker said it plans to sell 28 million shares at a price range of $115 to $125 each, which would raise about $3.5 billion and value the company at up to $26.6 billion, according to the company’s filing.
If the deal prices at or above the high end, it would be the largest tech IPO of 2026 so far. It would also mark a sharp increase in value from Cerebras’ $23 billion Series H round in February, when late-stage investors bought into a $1 billion financing.
⚡ New to this?
An IPO, or initial public offering, is when a private company sells shares to the public for the first time. Cerebras’ filing matters because it shows both strong demand for AI infrastructure companies and how closely tied major AI players like OpenAI are to the chip suppliers that power their systems.
Inference is the computing used when an AI model answers a prompt, so chips that do this faster or with less power can have real business value. The news also matters because a large IPO can set expectations for other big AI companies that may want to go public later.

If you build self-hosted AI agents, pay attention to the inference side of the stack, not just training. Cerebras is pitching speed and power efficiency for prompt processing, which is the part your agents hit every time they call a model.
For your own systems, measure tokens per second, latency, and watts per request before changing hardware. If you run multiple agents, benchmark the same workflow on GPUs and any alternative inference hardware so you know where the real bottleneck is.
Also track vendor financing and customer ties when choosing infrastructure partners. This story shows how loans, warrants, and customer contracts can shape access to chips and pricing, which can affect your capacity planning and long-term deployment costs.
Cerebras makes AI-specific chips built around its Wafer-Scale Engine 3, which it says is designed to compete with GPU-based AI chips. The company says its chip is faster for inference and uses less power than rivals. Inference is the part of AI computing used to process user prompts and generate outputs.
A successful IPO would benefit a long list of investors. According to Cerebras’ SEC filing, its largest shareholders with more than 5% stakes include Rick Gerson’s Alpha Wave, Benchmark through partner Eric Vishria, Lior Susan’s Eclipse, Fidelity, and Foundation Capital through partner Steve Vassallo.
The filing also lists other investors such as 1789 Capital, Abu Dhabi Growth Fund, Abu Dhabi’s G42, Altimeter, AMD, Atreides Management, Coatue, Moore Strategic Ventures, Tiger Global, Valor Equity Partners, and VY Capital. Cerebras also names a number of angel investors on its website, including OpenAI CEO Sam Altman, OpenAI president Greg Brockman, former OpenAI chief scientist Ilya Sutskever, OpenAI board member and Quora CEO Adam D’Angelo, and Intel CEO Lip-Bu Tan.
The company’s links to OpenAI are especially notable. Altman’s personal stake was not large enough to require disclosure in the SEC filings, but he was quoted in Cerebras’ S-1. Legal filings in Elon Musk’s lawsuit with OpenAI also said OpenAI had at one point considered acquiring Cerebras, though that deal never happened.
OpenAI later became one of Cerebras’ biggest customers. In December, OpenAI also loaned Cerebras $1 billion, secured by warrants that give OpenAI the right to buy more than 33 million shares, according to the S-1. That means OpenAI could end up with a much larger equity position if those warrants are exercised.
Cerebras’ path to the public markets has not been smooth. The company had hoped to go public in 2024, but the plan was delayed after a federal review of an investment from Abu Dhabi-based cloud provider G42, which Cerebras said remains a major customer. That first IPO attempt was later shelved.
The company returned to fundraising in 2025. In September, it raised $1.1 billion at an $8.1 billion post-money valuation, led by Fidelity and Atreides. A few months later, Cerebras signed a new multi-year agreement with OpenAI worth more than $10 billion, which included the loan and the warrants. In February, it raised another $1 billion in its Series H round.
Demand for the offering appears strong. Bloomberg reported that banks were already fielding about $10 billion in orders for the $3.5 billion share sale. If that demand holds, Cerebras could price above the announced range and raise more money while giving investors a bigger payday.
