Cerebras Systems designs AI accelerator chips meant to compete in a market long dominated by Nvidia. The California based company made its public market debut just over a month ago, and its first earnings report as a listed company sent shares into a steep slide on concerns about profit margins falling well short of what peers routinely post.

What Spooked Investors
Cerebras guided for full year 2026 adjusted gross margins in the 38% to 41% range. That compares poorly with the 47% it delivered in the first quarter, and it looks even thinner next to Nvidia's mid 70% margins and Advanced Micro Devices' mid 50% range. The guidance did land above the analyst consensus of roughly 29.6%, yet the direction of travel, downward from Q1, was enough to knock more than 17% off the share price in a single session and erase over 6 billion dollars in market value.
Analysts had already flagged two structural pressures. Cerebras builds unusually large chips, which tend to carry higher manufacturing costs per unit. The company is also renting its own systems back from an existing client to cover near term demand while it expands its data center footprint. Both factors squeeze the margin story in the short run.
The selloff also fits a broader pattern. Cerebras shares were already down more than 27% from their IPO price before this week's drop, as investor enthusiasm for AI infrastructure names has cooled and the sheer capital required to build out that infrastructure has come into clearer focus.
What the Numbers Say
At 186.72 USD, the stock is sitting just above its 52 week low of 185.22, a level that will be watched closely as a technical floor. The RSI of 33.83 is not yet in classic oversold territory below 30, but it is close enough that momentum traders will be paying attention. No earnings per share or price to earnings ratio is available given the company's early stage financials, and no dividend is on offer, so the investment case rests entirely on revenue growth and the eventual path to wider margins.
The bull case centers on two headline deals. Cerebras has a 20 billion dollar multi year agreement with OpenAI, and CEO Andrew Feldman confirmed on the post earnings call that OpenAI's GPT 5.4 model is running on Cerebras chips. Under the full scope of the contract, OpenAI is set to deploy 750 megawatts worth of Cerebras semiconductors. Morgan Stanley found enough in that picture to raise its price target on the stock to 273 dollars from 250 dollars. TD Cowen separately pointed to the OpenAI arrangement and a new agreement with Amazon Web Services as the pillars of long term growth. Feldman said AWS will begin using Cerebras chips in its data centers soon, with revenue from that relationship expected to flow within the next year.
The bear case is harder to dismiss. Gross margins that trail Nvidia by more than 30 percentage points raise real questions about pricing power and cost structure. If the company cannot close that gap as it scales, the premium implied by a nearly 50 billion dollar market cap will be difficult to defend. The near term reliance on renting back its own hardware is an unusual arrangement that adds cost complexity, and a cooling macro appetite for high valuation AI names means there is limited patience for execution stumbles.
The OpenAI and AWS Relationships in Context
The 20 billion dollar OpenAI deal is the most concrete evidence Cerebras has that its chips can win at scale. GPT 5.4 running on Cerebras hardware is a genuine proof point, not a letter of intent. The AWS relationship, still in the deployment phase, is a different kind of signal: it suggests hyperscalers are willing to diversify beyond Nvidia for at least a portion of their AI compute needs. Whether that translates into the margin improvement Cerebras needs is the question the next few quarters will have to answer.
Frequently Asked Questions
Why did Cerebras stock fall so sharply after earnings?
The company guided for full year 2026 gross margins of 38% to 41%, down from the 47% it posted in the first quarter. That trajectory, combined with a comparison that puts Cerebras well below Nvidia and AMD on margins, rattled investors even though the guidance came in above the analyst consensus.
What is the Cerebras and OpenAI deal?
Cerebras signed a 20 billion dollar multi year agreement with OpenAI. Under the deal, OpenAI will deploy 750 megawatts of Cerebras semiconductors, and CEO Andrew Feldman confirmed that OpenAI's GPT 5.4 model is already running on Cerebras chips.
Is Cerebras stock near its all time low?
As of June 21, 2026, the stock was trading at 186.72 USD, just above its 52 week low of 185.22. That level represents the lowest price since the company's IPO more than a month ago.
What did Morgan Stanley say about Cerebras after earnings?
Morgan Stanley raised its price target on CBRS to 273 dollars from 250 dollars, signaling continued confidence in the company's longer term prospects despite the margin miss.
Where Things Stand
Cerebras enters the back half of 2026 with a powerful client list and a stock price near the bottom of its post IPO range. The margin guidance disappointed, the RSI is flashing near oversold conditions, and the 52 week high of 386.34 feels like a distant memory. The AWS revenue ramp and the scale of the OpenAI deployment are the metrics worth watching in the quarters ahead.
