Cerebras reports Q2 2026 earnings with $210M core revenue, raises FY26 guidance

Cerebras Systems posted stronger-than-expected results for its second fiscal quarter of 2026, reporting $210 million in core revenue and raising guidance for both Q3 and the full year. The print arrived after the market closed on August 12, clearing the approximately $194 million that analysts had penciled in and extending what has been a remarkably consistent upward revision cycle since the company’s IPO earlier this year.

Wall Street had expected roughly 88% year-over-year core revenue growth heading into the print.

Where the numbers stand

Cerebras reported Q1 2026 total revenue of $193.4 million, up 94% year over year, with core revenue of $191.3 million, up 92% year over year. The Q2 result of $210 million in core revenue represents sequential growth on top of an already strong prior quarter.

The full-year 2026 core revenue guidance, which stood at $855 million to $865 million heading into this print, has now been revised upward. The prior midpoint of roughly $860 million already implied approximately 69% year-over-year growth.

In Q1, Cerebras reported a core gross margin of 47%. Heading into Q2, the company had already flagged that margins would compress, guiding to a range of 36% to 38%—a sequential decline of nearly ten percentage points.

The company behind the chip

Cerebras was founded in 2015 in Sunnyvale, California, and has built its identity around the Wafer-Scale Engine, or WSE—the largest chip built specifically for AI training and inference. Where conventional AI chips are small silicon dies packaged together on a board, Cerebras machines an entire silicon wafer into a single processor, sidestepping the interconnect bottlenecks that plague multi-chip architectures when handling very large models.

The company raised a $1 billion Series H round in early 2026 at a valuation of approximately $23 billion before going public. The May 2026 IPO raised between $5.5 billion and $6.4 billion, making it one of the largest tech listings of the year by proceeds.

Cerebras holds a multi-year agreement with OpenAI valued at over $20 billion, and has a collaboration with AWS giving it a hyperscaler distribution channel alongside its direct enterprise relationships.
