Cerebras Systems formally launched the roadshow for its initial public offering on Monday, May 4, 2026, marking one of the most closely watched AI hardware listings of the year. The Sunnyvale-based wafer-scale chipmaker plans to sell 28 million Class A shares in a price range of $115 to $125 under the ticker CBRS on the Nasdaq Global Select Market.
At the high end of the range, the offering would deliver roughly $3.5 billion in gross proceeds and a market capitalization of about $26.6 billion. If underwriters exercise their option to purchase an additional 4.2 million shares, total proceeds could climb to approximately $4.03 billion. Pricing is expected on May 13.
A direct challenge to Nvidia
Cerebras has spent the past several years pitching its Wafer-Scale Engine architecture as a faster alternative to GPU clusters for training and inference workloads. The company's pitch to public-market investors leans heavily on customer concentration that would be the envy of most chip startups: a multi-year contract with OpenAI reportedly valued at over $20 billion, requiring Cerebras to absorb 750 megawatts of compute capacity for ChatGPT-related workloads. OpenAI has also extended a $1 billion working capital loan to help Cerebras finance the deployment.
The order book is reportedly deep. According to communications cited in underwriter materials, potential customer orders have already surpassed $10 billion. Amazon Web Services signed a binding term sheet in March 2026 to deploy Cerebras systems inside its data centers, broadening the company's hyperscaler footprint beyond OpenAI.
Financial inflection ahead of listing
The filings show a company that flipped to profitability just in time for the listing window. Full-year 2025 revenue nearly doubled to $510 million from $290.3 million in 2024, and Cerebras swung from a $484.8 million loss to an $87.9 million profit over the same period. That trajectory will be central to the roadshow pitch as the company asks investors to underwrite further capital expenditure on wafer-scale systems.
Morgan Stanley, Citigroup, Barclays, and UBS Investment Bank are leading the offering as book-running managers. Mizuho and TD Cowen are listed as bookrunners, with Needham & Company, Craig-Hallum, Wedbush Securities, Rosenblatt, Academy Securities, Credit Agricole CIB, MUFG, and First Citizens Capital Securities serving as co-managers.
What it signals for the AI chip market
Cerebras is the first pure-play AI silicon company to launch a US IPO roadshow since the post-GPT-5 capex surge accelerated in late 2025. A successful pricing would test investor appetite for Nvidia alternatives at a moment when hyperscalers are actively diversifying suppliers, and it would hand Cerebras the balance sheet needed to scale wafer-scale deployments to gigawatt class. A weak reception, by contrast, would reinforce the view that frontier inference economics still favor the incumbent GPU stack.
Either way, the May 13 pricing date now joins the short list of catalysts that AI infrastructure investors are watching this quarter.
