Cerebras Shares Slump After Q2 Revenue Miss in AI-Chip Clinch

Cerebras Systems’ stock fell about 16% after-hours after a Q2 revenue miss, with revenue of $180.11 million vs $194.23 million expected and an adjusted loss of $6.91 million, though the cloud business grew to $126 million and total sales rose 74.3% to $180.11 million. The company raised 2026 revenue guidance to $880–$890 million and expects 41–43% gross margin as it scales its wafer-scale engine amid intense competition from Nvidia; a multiyear OpenAI compute deal remains a key growth driver.
