Cerebras Systems beat its first earnings bar and still watched its stock fall 10 percent
Cerebras Systems reported Q1 2026 revenue of $193.4 million, up 92% year-over-year, and announced a $20 billion multi-year deal with OpenAI. But guidance for gross margins to compress to 36-38% in Q2 sent shares down 10% in after-hours trading, extending a decline to roughly 28% from the AI chipmaker's IPO-day peak. The question now is whether the margin squeeze is a temporary scaling cost or a structural ceiling for non-Nvidia AI inference chips.
