Cerebras boosts IPO size and price as demand for AI chips surges

Cerebras Systems moved to widen and sweeten its initial public offering as demand for the AI chipmaker’s shares surged, a sign that investors are still willing to pay up for exposure to the companies closest to the compute boom.

The Sunnyvale, California-based company was considering a new price range of $150 to $160 a share, up from an earlier $115 to $125, while also increasing the offering to 30 million shares from 28 million. At the top of that range, Cerebras would raise about $4.8 billion, up from roughly $3.5 billion under the original terms. Orders for the deal were already more than 20 times the shares available, according to the report, setting up a test of whether hunger for AI hardware is rooted in fundamentals or in fear of missing the next Nvidia-scale winner.

Cerebras has tried to present itself as more than a speculative chip story. The company reported $510 million in revenue in 2025, up about 76% from 2024, and said its processors are built for running advanced AI models, with particular strength in inference, the computing that lets models answer user prompts. That positioning matters because inference has become one of the most closely watched battlegrounds in AI infrastructure, where cloud providers, model makers and governments are all trying to secure faster and more specialized chips.

The customer list has also strengthened. Cerebras secured Amazon and OpenAI after its earlier public offering attempt, and OpenAI loaned the company $1 billion and received a warrant to buy Cerebras stock, according to its April filing. Those ties give the IPO more credibility than a typical pre-revenue AI play, but they also underline how dependent the company remains on a small circle of powerful customers and partners.

That concentration risk is already part of Cerebras’ record. G42, the United Arab Emirates-based AI company, accounted for more than 80% of Cerebras’ revenue in the first half of 2024, a relationship that drew scrutiny from the Committee on Foreign Investment in the United States before being cleared. The episode put Cerebras in the middle of a larger policy debate over who controls the supply chain for advanced AI compute, especially as chip demand collides with national security concerns.

The offering, led by Morgan Stanley, Citigroup, Barclays and UBS, is set to list on the Nasdaq Global Select Market under the ticker CBRS. If priced at the top of the revised range, it would be the biggest IPO globally so far in 2026 and could value the company at as much as $24.5 billion. That valuation would show just how hot the market has become for AI infrastructure, but it would also leave investors asking the harder question: whether Cerebras can scale beyond a narrow customer base and compete in a market still dominated by Nvidia.
