Cerebras Systems Inc. is poised to price its initial public offering above the recently raised $150-to-$160 per share range, according to a Tuesday report from Bloomberg. The surge is driven by extraordinary demand for AI chip stocks, with orders exceeding 20 times the available shares, as reported by Reuters. The company is offering 30 million shares, which at $160 each would raise $4.8 billion before any underwriter allotments.
The IPO is on a tight schedule: Cerebras will set the final price on Wednesday, with shares set to begin trading on Thursday on the Nasdaq under the ticker CBRS. This offering gives public investors a fresh opportunity to invest in the AI infrastructure story, extending beyond Nvidia and the major cloud providers. Morningstar estimates that the updated price range could value Cerebras at nearly $50 billion on a fully diluted basis.
Demand for the offering has been robust, prompting Cerebras to increase both the number of shares and the price range. The company had initially targeted 28 million shares at $115 to $125 each. The books are being managed by Morgan Stanley, Citigroup, Barclays, and UBS, according to Reuters.
An IPO marks a company's debut on public markets. Cerebras focuses on a specific niche within AI: inference, where models deliver answers, rather than the heavy training phase. In January, OpenAI announced that Cerebras would supply 750 megawatts of low-latency computing capacity for its platform, with rollout scheduled in phases through 2028.
The OpenAI partnership adds complexity to the picture. In April, Reuters reported that OpenAI had committed over $20 billion over three years for Cerebras-powered servers, a deal that might grant the ChatGPT creator warrants for a minority stake. Reuters could not independently confirm those details at the time.
Morningstar senior equity analyst Brian Colello described the valuation surge as “remarkable.” He noted that Cerebras was valued at $8 billion in October, before its deals with OpenAI and Amazon Web Services accelerated the IPO narrative. PitchBook analyst Dimitri Zabelin told Morningstar that the AI hardware landscape has shifted toward inference, where speed and cost per query are paramount.
Cerebras is not alone in eyeing public markets. Nvidia continues to dominate AI accelerators, while AMD is intensifying its pursuit of the same customer base. CoreWeave's post-IPO surge has become a benchmark for investor enthusiasm in AI infrastructure. According to Morningstar, CoreWeave raised $1.5 billion in its March 2025 IPO, achieving a $23 billion fully diluted valuation. Since then, its stock has soared 162%.
However, risks remain significant. Reuters Breakingviews reported that Cerebras generated over $500 million in revenue last year but operated at a loss. If the AI chip frenzy wanes, the company's implied market value could appear stretched relative to sales. The analysis also noted that the valuation excludes sizable employee option grants and warrants linked to OpenAI and Amazon.
Customer concentration is another pressure point. According to TSG Invest, G42 and MBZUAI, both based in Abu Dhabi, account for roughly 86% of Cerebras' projected 2025 revenue. Drew Spaventa, founder of TSG Invest, stated that the group remains “cautious about a customer base this concentrated.” Post-listing, Cerebras faces two major challenges: convincing the market that the OpenAI partnership can expand, and proving it is not just a niche supplier riding a single wave.
