Cerebras Raises 2026 Outlook as Q2 Core Revenue Doubles
Cerebras reported $180.1 million in second-quarter GAAP revenue and $209.9 million in core revenue, up 74% and 103% from a year earlier, respectively. The AI-infrastructure company raised its 2026 core-revenue outlook to $880 million-$890 million, but its shares fell about 14% in extended trading after the August 12 report.
Cerebras Systems reported second-quarter 2026 results on August 12, raising its full-year outlook while its shares fell about 14% in extended trading. The company separated its reported figures into GAAP results and what it calls core non-GAAP results, an important distinction for reading the quarter.
Revenue grew, but the two measures diverged
For the quarter ended June 30, Cerebras reported $180.1 million in GAAP revenue, up 74% from a year earlier. Its core revenue was $209.9 million, up 103%. The company says core results exclude items including data-center pass-through revenue and costs, stock-based compensation, and non-cash amortization of customer warrants.
Cloud and other services drove much of the growth. GAAP cloud revenue reached $126.0 million, up 281% year over year, while core cloud revenue was $127.7 million, up 287%. Cerebras reported a 14% GAAP gross margin and a 41% core gross margin. CNBC reported a $450.5 million net loss, with $386.6 million tied to stock-based compensation.
Cerebras raised its full-year targets
The company now expects 2026 core revenue of $880 million to $890 million, up from its previous $855 million-$865 million range. It also guided to a 41%-43% full-year core gross margin. For the third quarter, Cerebras expects core revenue of approximately $214 million-$216 million and a 38%-40% core gross margin.
The filing also says Cerebras has more than 600 megawatts of data-center capacity live or under contract for delivery by the end of 2027 and plans to increase manufacturing capacity more than tenfold during 2026. Those are company targets, not completed deployments.
What the quarter signals for AI infrastructure
The mix shift toward cloud services shows why inference capacity, data-center access, and manufacturing execution are becoming linked operating constraints for AI-chip vendors. Cerebras says its remaining performance obligations reached $25.4 billion, but converting contracted demand into recognized revenue will depend on delivering the underlying systems and capacity.
For practitioners and buyers, the useful comparison is not only headline growth. The gap between GAAP and core revenue, the 14% versus 41% gross-margin measures, and the timing of contracted capacity all matter when evaluating the economics and delivery risk behind Cerebras's fast-inference expansion.
