Cerebras Systems Inc. Class A Common StockShares fell 12% after guidance of declining gross margins despite revenue beat.

Cerebras shares fell nearly 12% after the company reported first-quarter 2026 results, despite revenue jumping 94% year over year to $193 million and beating the $181 million consensus estimate. Investors focused on management's guidance that adjusted gross margin will drop to between 38% and 41% for 2026 from 47% in the first quarter, as the company rents out systems to fulfill its $20 billion contract with OpenAI rather than selling them. The sell-off comes amid broader pressure on AI chip stocks, with Nvidia and Broadcom each down about 9% over the past month, as skepticism grows over whether massive AI investments will translate into profits. Cerebras trades at a trailing price-to-sales ratio of 74, far above the tech sector average of about 10, adding to volatility concerns.
