Cerebras revenue beat expectations as Cerebras Systems reported third-quarter growth, raised its outlook and secured a new Microsoft agreement, sending the AI chipmaker’s stock up 17 percent in extended trading. The company delivered core adjusted revenue of 230.9 million dollars, comfortably above Wall Street’s target of 214.7 million dollars, while record GAAP revenue reached 210.8 million dollars.
Cerebras revenue beat: Growth and better margins
CNBC reported that core revenue grew 70 percent from 135.7 million dollars, compared with 103 percent growth in the second quarter. Cerebras also disclosed core cloud and other services revenue of 144.9 million dollars, up 272 percent year over year, while GAAP cloud revenue grew 265 percent to a record 141.9 million dollars.
The profitability picture remained mixed. According to SiliconANGLE, Cerebras reported a loss before certain costs, including stock compensation, of 67 cents per share, trailing Wall Street’s guidance for a 14 cent per share loss. The company noted that accounting differences meant its results were not directly comparable with that guidance, as its adjusted figures exclude customer warrant amortization, stock-based compensation, data center pass-through revenue and costs, and certain other items.
There was clearer progress at the operating level. SiliconANGLE reported that core operating margin was minus 14 percent, significantly better than guidance of minus 24 percent from three months earlier. Core gross margin was 41 percent, up both sequentially and year over year. Cerebras also raised its full-year 2026 core revenue outlook to between 940 million and 960 million dollars, with a core gross margin of 42 to 44 percent.
Microsoft expands the customer mix
CNBC reported that Microsoft signed its agreement with Cerebras in October and that revenue is expected to begin appearing in the first quarter of fiscal 2027. The arrangement gives Cerebras another major hyperscaler relationship alongside Amazon Web Services and Oracle. It also positions the chipmaker to compete more directly for the hyperscaler computing budgets that Microsoft already directs toward providers such as Nebius.
Cerebras did not disclose many details about the Microsoft agreement, leaving its size and economics uncertain. Yahoo Finance described it as one of two new commercial deals with hyperscalers, while the company’s announcement identified Microsoft as a top three hyperscaler and said more information would be shared next year. TIKR argued that the relationship makes Cerebras look less dependent on a single customer, but the first Microsoft revenue in early 2027 will provide the first tangible test.
Chief Executive Andrew Feldman said Cerebras has an advantage over competitors that are struggling to keep pace with customer demand and manage growing order backlogs. He also pointed to hardware opportunities created by long lead times for GPUs and higher costs, referring to Nvidia’s graphics processing units. SiliconANGLE reported that Nvidia still dominates the AI chip industry, accounting for over 90 percent of all chip sales according to some analysts.
Guidance points to another step up
Cerebras expects fourth-quarter revenue of between 310 million and 330 million dollars and a core gross margin of 47 to 49 percent. CNBC reported that Wall Street analysts surveyed by LSEG were looking for revenue of 271 million dollars and a core gross margin of 42.1 percent. Yahoo Finance separately cited consensus revenue of 271.2 million dollars.
The company also expects revenue to triple in 2027. TIKR calculated that tripling the midpoint of the new 2026 range would produce about 2.85 billion dollars in revenue, slightly below Wall Street’s long-term forecast of 2.92 billion dollars for fiscal 2027. That target depends on the company maintaining its rapid growth while adding capacity, serving a broad customer base and converting contracts into delivered services.
Backlog brings opportunity and execution risk
Cerebras reported 26.1 billion dollars of remaining performance obligations as of September 30. Its hardware and cloud services backlog increased from 25 billion dollars in August to 26 billion dollars at the end of the quarter. CFO Bob Komin said on the earnings call that OpenAI makes up the majority of the backlog, an important qualification because it concentrates both the opportunity and the delivery risk.
Crypto Briefing reported that Cerebras has secured 700 megawatts of data center capacity under contract. Cerebras also said its pipeline for high-speed AI inference increased by more than 10 times during the quarter. However, TIKR reported that delays involving land, power and construction left the company behind on early capacity deliveries to OpenAI, which is why fourth-quarter cloud revenue should be roughly flat.
This makes physical execution more important than contract announcements alone. Until the relevant data centers come online, Cerebras cannot fully deliver on the OpenAI arrangement behind most of its backlog. The company is evaluating financing options to meet ramping demand, CNBC reported, while noting that capital has become harder to secure amid nervousness about the scale of spending on AI infrastructure. Cerebras entered the period with 7.8 billion dollars in cash, cash equivalents, restricted cash and short-term investments, plus debt capacity of 850 million dollars.
A valued but volatile stock
The market response was strong but did not erase the doubts surrounding the business. CNBC reported that Cerebras shares had fallen about 47 percent since the company debuted on Nasdaq in May. Yahoo Finance said the stock jumped 10 percent after the report, while CNBC and Crypto Briefing recorded gains of 17 percent and 12 percent in extended trading at different points in the trading session.
Valuation also reflected substantial uncertainty. TIKR reported that Cerebras shares ended Thursday at 16 times forward sales, compared with an average of 35 times since the listing and a peak of 63 times. Cerebras remains a loss-making challenger whose wafer-scale processors are designed to accelerate AI workloads, but its valuation depends on converting a large backlog, overcoming infrastructure delays and proving that new customers such as Microsoft can become material contributors. The Cerebras revenue beat delivered an encouraging quarter, yet the next test will be execution against the promises embedded in the 26.1 billion dollars of remaining performance obligations.
