Cerebras has filed for an initial public offering at a $26.6 billion valuation, the top end of its range, in one of the most closely watched AI hardware listings of the year. The company plans to sell 28 million shares at $115 to $125 each, raising roughly $3.5 billion under the ticker CBRS, with pricing set for May 13 and trading starting the next day.
The headline number is large, but it lands in a market that has redefined what large means. Jaeden Schafer noted on the podcast that the same week Cerebras lined up $3.5 billion, an OpenAI spinoff embedding developers inside private equity portfolio companies pulled in around $4 billion of its own. It just goes to show you how absolutely astronomical these rounds of funding are for anthropic and opening AI right now you kind of have these giants just scooping up so much money, he said.
The more consequential detail sits below the IPO headline. In December, OpenAI extended Cerebras a $1 billion loan secured by warrants on roughly 33 million shares — a position that converts at listing into one of the largest single holdings in the newly public chip company. Schafer said on the show that "opening, I just became on paper, one of the largest single shareholders of this publicly traded AI chip company that is going to compete head to head with Nvidia, right?"
Key facts
- 01Cerebras filed for an IPO targeting a $26.6 billion valuation, selling 28 million shares at $115 to $125 to raise roughly $3.5 billion.
- 02Shares will trade under the ticker CBRS, with pricing set for May 13 and trading beginning the following day.
- 03OpenAI loaned Cerebras $1 billion in December, secured by warrants on about 33 million shares that convert at IPO.
- 04Anthropic has locked into Google TPUs and Amazon Trainium, eroding Nvidia's near-monopoly position from 2024.
That structure puts OpenAI in an unusual position: bankrolling a direct rival to Nvidia, currently one of its largest cost centers. Sam Altman's company has signaled for years that it wants to diversify away from a single silicon supplier, and the Cerebras stake is the most concrete expression of that strategy yet.

The economics of the dependency are central. Nvidia decides who gets its newest chips through allocation, not open-market sale, and every major lab is fighting for the same shipments. For a company trying to scale capacity as aggressively as OpenAI, sitting at the back of that queue — or watching a future allocation get cut — is a planning risk as much as a cost one. A meaningful equity stake in an alternative supplier softens both sides of the negotiation.
Cerebras itself has spent years pitching its wafer-scale architecture as a credible challenger for AI training and inference workloads. A $26.6 billion valuation prices it as more than a niche specialist, but the $3.5 billion raise still lags the war chests being assembled by its model-maker customers, underlining how capital-intensive the inference build-out has become.
The competitive map around Nvidia has also shifted. Anthropic has locked into Google's TPU stack and is also using Amazon's Trainium silicon, while OpenAI is now both an Nvidia customer and a Cerebras shareholder. Schafer argued that "the dependency story for Nvidia is not what it was in 2024," pointing to credible competitors and big labs committing to them.
For public-market investors, the CBRS listing offers a rare pure-play bet on the thesis that frontier AI compute will not stay consolidated on one vendor. For OpenAI, it converts a loan into leverage — both financial and strategic — over a supplier it now has every incentive to see succeed.
