Cerebras Systems announced plans to sell 28 million shares at $115 to $125 each, seeking to raise roughly $3.5 billion and achieve a market valuation of up to $26.6 billion. The AI‑chipmaker’s filing lists a roster of high‑profile investors—including OpenAI founders Sam Altman and Greg Brockman, Fidelity, and Tiger Global—many of whom stand to profit from a successful debut. A $1 billion loan from OpenAI, secured by warrants on over 33 million shares, underscores the deep ties between the two firms. If demand holds, the offering could become the largest tech IPO of 2026.
Cerebras Systems, the San Francisco‑based maker of wafer‑scale AI processors, filed paperwork on Monday indicating it will offer 28 million shares priced between $115 and $125. At the top of that range, the company would raise $3.5 billion and post a market capitalization of $26.6 billion, making it the biggest tech listing so far this year.
The filing reveals a long‑list of shareholders holding more than a five‑percent stake each. Among them are Benchmark’s Alpha Wave fund, Lior Susan’s Eclipse, Fidelity, and Foundation Capital. International investors such as Abu Dhabi Growth Fund, G42, and Altimeter also appear, alongside a handful of well‑known angels—OpenAI founder Sam Altman, co‑founder Greg Brockman, former OpenAI chief scientist Ilya Sutskever, Quora CEO Adam D’Angelo, and Intel’s Lip‑Bu Tan.
OpenAI’s connection to Cerebras goes beyond mere angel investment. In December, the nonprofit‑turned‑capped‑profit company loaned Cerebras $1 billion, a deal secured by warrants that let OpenAI buy more than 33 million shares. While OpenAI is not a major shareholder today, the warrants could translate into a sizable equity position if the IPO succeeds.
Cerebras had originally slated an IPO for 2024, but a federal review of a strategic investment from Abu Dhabi‑based cloud provider G42 forced a postponement. The company later raised $1.1 billion in September at an $8.1 billion valuation, then closed a $1 billion Series H round in February, its last mega‑fundraise before going public.
Bankers report that orders for the offering already total $10 billion, far exceeding the $3.5 billion of shares on the market. Such demand suggests the final pricing could land at the high end of the range—or even above it—delivering more cash to Cerebras and higher returns for its early backers.
The chip at the heart of Cerebras’ pitch is the Wafer‑Scale Engine 3, a single‑piece processor that claims faster inference performance while consuming less power than conventional GPU‑based solutions. If the market embraces the technology, the IPO could signal renewed appetite for large‑scale, AI‑specific silicon, a sector that has seen mixed results in recent years.
Analysts note that a successful Cerebras debut would not only validate the company’s engineering approach but also set a benchmark for other high‑profile tech listings slated for later this year, such as SpaceX, Anthropic, and a potential OpenAI offering.
With banks already fielding orders worth nearly three times the share amount, investors appear ready to back the chipmaker’s growth story. Whether the stock lands at $115 or $125 per share, Cerebras is poised to become a headline act on Wall Street’s 2026 calendar.
