Details
Q2 revenue $180M, +74% YoY
Revenue grew 74% year-over-year to $180M in Q2 2026 but missed quarterly analyst estimates, triggering an after-hours sell-off.
Cloud revenue ~4x to $126M
Cloud compute-as-a-service business roughly quadrupled versus the year-ago quarter, becoming the dominant revenue segment.
Hardware revenue fell to $54.1M
Direct chip hardware sales declined from $70.3M a year ago to $54.1M, as more customers shift toward cloud access rather than hardware ownership.
2026 guidance raised to $880M–$890M
Updated from previous forecast of $855M–$865M, implying strong second-half demand expectations.
CBRS dropped ~16% after hours
Stock had gained 11.6% during regular trading (up 15.5% week-to-date) before plunging roughly 16% in the extended session on the revenue miss.
On-chip memory bypasses HBM crunch
Cerebras' wafer-scale engine (WSE) places memory directly on the chip, insulating it from the HBM supply crunch raising Nvidia's prices. CEO Feldman: 'Nvidia's prices have gone through the roof because of HBM prices.'
WSE on TSMC 5nm, less supply pressure
Cerebras uses TSMC's 5nm manufacturing process, which has less capacity pressure than the 2nm and 3nm nodes used by AMD and Nvidia, improving supply reliability.
Nvidia intensifying inference competition
Nvidia has stepped up efforts to capture the AI inference market, including licensing technology from startup Groq — putting pressure on Cerebras to demonstrate scalable profitability.

What This Means
Cerebras' Q2 results reveal an AI chip company at a strategic inflection point: cloud revenue is surging (up 4x) while hardware sales decline, suggesting enterprises prefer compute-as-a-service over direct chip ownership — a model shift that could prove durable if it improves margins and reduces capital intensity. The raised annual guidance signals strong second-half demand, but the revenue miss and after-hours selloff show how unforgiving markets are for AI infrastructure plays priced for perfection. Cerebras' on-chip memory architecture may be its most durable competitive advantage right now: as HBM scarcity keeps Nvidia's prices elevated, Cerebras can offer AI inference at more predictable cost — but it still needs to prove it can scale profitably against Nvidia, which is simultaneously improving inference efficiency and targeting the same workloads.
Sentiment
Disappointed reaction focused on revenue miss, margin pressure and high expectations despite growth, cloud surge and raised guidance
“CEREBRAS $CBRS -7% AFTER HOURS 🚨 Q2 EPS: -$2.98 vs -$1.67 est. ❌ Revenue: $180.1M vs $193.6M est. ❌ Revenue still surged +74% Y/Y. Core operating margin improved ~2,600 bps Y/Y to -16%, but the headline top + bottom-line misses are weighing on shares.”
“When you miss on things like EPS, revenue, hardware revenue and gross margin by as much as Cerebras did in their Q2 earnings report, it pretty much offsets any positives from the quarter (raised Q3 and FY guidance). Justified why the stock is down 16% in AH. $CBRS”
“Wall Street Found a New Way to Punish Good News $CBRS Cerebras beat expectations on revenue and on losses in its second quarter as a public company, and the stock still fell 15% after hours. The tape had already run 32% in August before the report. The results cleared the estimates. The price had already cleared the results.”
“$CBRS | CEREBRAS SYSTEMS Q2 2026: AI demand is exploding — but Wall Street wanted more. Cerebras delivered a mixed quarter: Revenue: $180.1M | +74.3% YoY (miss), Cloud revenue: ~$126M | nearly 4X YoY, Hardware revenue: $54.1M vs $70.3M YoY, FY26 revenue guidance raised... Wall Street's reaction was brutal: shares fell 16% after hours, despite the company raising its full-year outlook. The bigger story is the $20B multiyear OpenAI agreement.”
Split
Strong cloud growth and raised guidance (~60%) vs. revenue miss, hardware decline and margin compression (~40%) driving the selloff.
