Shares of Cerebras Systems Inc. (NASDAQ:CBRS) dropped sharply after the company guided for full year gross margins well below what it posted in the first quarter, raising pointed questions about the profitability of its unusual manufacturing approach.

The Margin Warning That Sparked the Drop
Cerebras issued its debut earnings as a public company and immediately handed skeptics ammunition. The California based chipmaker guided for adjusted gross margins of 38% to 41% for the full year 2026, a meaningful step down from the 47% it reported in the first quarter. Even taken on its own terms, that forecast trails rivals by a wide margin. Nvidia operates in the mid 70% gross margin range; Advanced Micro Devices sits in the mid 50s. Cerebras is projecting roughly half of what Nvidia earns on each dollar of revenue.
Analysts had penciled in around 29.58% for the year, so the guidance technically beat the street estimate. But beating a low bar is a different thing from inspiring confidence, and the market's reaction made that distinction clear.
Two structural factors are pressing on margins. Cerebras builds unusually large chips, and larger chips introduce more manufacturing complexity and cost. The company is also renting back its own systems from an existing client to cover near term demand while it expands its data center capacity. That arrangement, essentially paying to use hardware it originally sold, is a direct drag on profitability and is not a one-off cost.
The OpenAI and Amazon Cases for the Bull
Not everyone walked away from earnings bearish. Morgan Stanley lifted its price target on CBRS to 273 USD from 250 USD. TD Cowen pointed to partnership agreements with Amazon and OpenAI as the central pillars of any long-term growth thesis.
The OpenAI deal is genuinely large. Cerebras has signed a 20 billion dollar multi-year agreement with the ChatGPT maker, and CEO Andrew Feldman confirmed on the post-earnings call that OpenAI's GPT 5.4 model is already running on Cerebras chips. Under the full scope of the deal, OpenAI is scheduled to deploy 750 megawatts worth of Cerebras semiconductors. Meanwhile, Feldman said Amazon Web Services will begin using Cerebras chips in its data centers in the near term, with revenue from that relationship expected to start flowing within the next year.
Those are real contracts with two of the most visible names in the AI industry. The question worth asking is whether the revenue they generate will actually translate into the margins the market expects from a premium-priced chip company.
What the Numbers Say
With an RSI of 33.67, CBRS is approaching oversold territory on a technical basis, which sometimes precedes a short term stabilization. But momentum alone is not a catalyst, and a stock can remain oversold for extended periods when the fundamental picture is genuinely in question.
The market cap of 49.79 billion USD prices in substantial future growth even after the selloff. No P/E ratio or EPS figure is publicly available at this stage, which itself signals that the company is not yet generating net income on a GAAP basis. Investors are paying for a growth story, not current earnings. The 52-week range of 185.22 to 386.34 shows just how violently sentiment has shifted: the stock has shed more than half its peak value and is now trading essentially at its floor. There is no dividend, so holders have no income cushion while they wait for the thesis to play out.
The broader context matters. Cerebras shares are down more than 27% from their IPO debut. AI enthusiasm that drove the initial pop has cooled as investors grow more cautious about the enormous capital spending required to build out AI infrastructure, and about whether the companies supplying that infrastructure can sustain high margins over time.
Bull Case Versus Bear Case
The bull case rests on the scale and credibility of the OpenAI and AWS relationships, the possibility that margins recover as Cerebras builds out its own data center capacity and reduces its reliance on rented systems, and the argument that any chip supplier embedded in GPT 5.4's production stack has a durable competitive position.
The bear case is harder to dismiss. Margins are structurally lower than competitors because of chip size and supply chain constraints. The company is renting back hardware at a cost, a dynamic that could persist longer than management suggests. The valuation at nearly 50 billion dollars requires a lot of things to go right. And AI infrastructure spending could slow or consolidate in ways that favor entrenched players like Nvidia over newer entrants.
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 47% in the first quarter. Investors interpreted the step down as a sign of structural cost pressure, even though the guidance came in above some analyst forecasts.
How does Cerebras' margin profile compare to Nvidia and AMD?
Nvidia operates in the mid 70% gross margin range and AMD in the mid 50s. Cerebras' 2026 guidance of 38% to 41% is significantly below both, which analysts attribute in part to its larger chip design and short-term supply arrangements.
What is the OpenAI deal worth?
Cerebras has a 20 billion dollar multi-year agreement with OpenAI. Under its terms, OpenAI is set to deploy 750 megawatts of Cerebras semiconductors, and CEO Andrew Feldman confirmed GPT 5.4 is already running on the company's chips.
Does Cerebras pay a dividend?
No. Cerebras does not currently pay a dividend, which means shareholders have no income component to offset price volatility while the company pursues growth.
Where CBRS Goes From Here
Cerebras enters the back half of 2026 with two marquee customers, a balance sheet shaped by a significant IPO, and a margin profile that has already disappointed once. The RSI near 33 suggests the worst of the near term selling may be close to exhausting itself, but the structural margin gap versus Nvidia and AMD is not a number that closes quickly. How fast Cerebras can convert its OpenAI and AWS commitments into improving profitability will determine whether today's floor becomes a foundation or just a stop on the way down.
