Cerebras Eyes $26.6B Blockbuster IPO
Cerebras Systems filed to sell 28 million shares at $115–$125 each, a range that would raise about $3.5 billion and imply a roughly $26.6 billion market capitalization at the high end. The AI chipmaker, maker of the Wafer-Scale Engine 3 which it says is faster and more power-efficient for inference than GPU alternatives, counts major investors and customers across the venture and sovereign-capital spectrum. OpenAI has a close commercial relationship with Cerebras—including a $1 billion loan secured by warrants that could let OpenAI buy over 33 million shares—and is one of its largest customers. The SEC filing names top shareholders (Alpha Wave, Benchmark, Eclipse, Fidelity, Foundation Capital) and numerous other institutional and angel backers. Banks are reporting strong demand, with coverage noting roughly $10 billion of orders against the $3.5 billion offering size.
A large IPO for an AI-hardware company signals investor appetite for AI infrastructure and could affect valuation comps and supply for AI compute — relevant to broader tech and AI ecosystems but not directly industry-shifting for AdTech/MarTech.

Cerebras Raises IPO Range, Seeks up to $4.8B
Cerebras Systems raised the price range for its initial public offering to $150–$160 per share, according to a May 11 filing, up from a range disclosed the prior week. At the high end of the new range the company could raise as much as $4.8 billion and reach a fully diluted valuation of about $48.8 billion. Nasdaq expects the IPO to occur on May 14, 2026. Cerebras, an AI-chipmaker that sells both hardware and cloud services, argues its chips outperform and cost less than GPUs from incumbents such as Nvidia; it has secured a $20 billion-plus commitment from OpenAI. The company is expanding into customer data centers and cloud partnerships (including AWS), and has been mentioned in courtroom testimony about potential merger talks involving OpenAI and Elon Musk.
Cerebras Files for IPO Again; OpenAI Is Major Customer
Cerebras, a maker of high-performance AI processors, filed an updated prospectus aiming to sell 28 million shares at $115–$125 each in a Nasdaq initial public offering, raising up to $3.5 billion and implying a market value as high as $26.6 billion. The filing follows a February valuation of about $23 billion and a previously withdrawn 2024 IPO attempt. Cerebras has shifted toward operating cloud services using its chips and counts OpenAI as a major customer (including a deal to provide up to 750 MW of AI computing power through 2028 worth over $20 billion). The company reported roughly $510 million in revenue (about 76% year-over-year growth) and showed $87.9 million in net income for the fourth quarter. CEO and co-founder Andrew Feldman is not selling shares in the offering; underwriters may exercise an option to buy an additional 4.2 million shares.
Cerebras Raises $5.5B in IPO
Cerebras Systems completed a blockbuster IPO on May 14, 2026, raising roughly $5.55 billion at an $185 offering price and opening sharply higher in its Nasdaq debut. Shares peaked near $386, closed the first day around $311 and implied a market capitalization of roughly $95 billion. The company, founded in 2015, sells wafer-scale processors designed for AI training and inference and reported about $510 million in revenue last year (up 76% year-over-year). CNBC’s Jim Cramer said Cerebras has compelling technology and major commercial partnerships (including multiyear deals with OpenAI and deployments with Amazon Web Services) but warned the post-IPO valuation is difficult to justify and advised investors not to chase the stock given the stretched revenue multiple.
