Strong revenue growth failed to calm Wall Street after the chipmaker’s first post-IPO earnings
Cerebras Systems had all the ingredients for a triumphant Wall Street debut — a landmark IPO, a blockbuster deal with OpenAI, and revenue nearly doubling year over year. Then the company told investors what was coming next, and the stock dropped 8% in after-hours trading.
Cerebras reported its first quarterly earnings since going public in May, with revenue rising 92% from the same period a year earlier. The stock fell in extended trading after the company forecast a drop in its gross margin going forward. The results laid bare a tension that will define Cerebras for the next several quarters — explosive growth on one side, and the cost of sustaining it on the other.
What the numbers actually showed
The quarter itself was strong by most measures. Cerebras posted GAAP quarterly revenue of $193.4 million, with core revenue up 92% from a year ago. The company also announced a multi-year deal with OpenAI valued at more than $20 billion and launched a partnership with Amazon to bring its fast inference technology to AWS.
Net losses narrowed significantly compared to a year earlier. The company entered the quarter with more than $3 billion in cash after raising $6.4 billion through what became the largest semiconductor IPO on record. On paper, this was a business accelerating in every meaningful direction. Hardware revenue jumped 59% year over year. Cloud and services revenue nearly tripled. The numbers told a story of a company firing on all cylinders — right up until management opened up about what comes next.
The margin forecast that spooked investors
The problem was what Cerebras said about the road ahead. For the second quarter of 2026, Cerebras projected core gross margin in the range of 36 to 38%, down from 47% reported in the first quarter — a significant step down that signaled rising costs as the company scales its infrastructure aggressively.
For a company that went public at $185 per share and briefly carried a valuation north of $80 billion, margin compression in the early quarters of its public life is precisely the kind of signal that makes investors nervous. The stock had already fallen about 28% from its first-day close before these results were released. A drop of that magnitude, before a single earnings report, reflected just how high expectations had been set during the IPO roadshow.
The bigger questions Cerebras still has to answer
Roughly 86% of Cerebras revenue in 2025 came from two UAE-affiliated customers, a concentration that analysts have flagged as a meaningful risk as the company tries to broaden its base beyond Abu Dhabi.
The OpenAI deal changes that story meaningfully — a $20 billion commitment from one of the most powerful names in AI is not something to dismiss lightly. The Amazon partnership adds another layer of distribution credibility, pairing Cerebras chips with AWS infrastructure to reach startups and enterprise customers at scale. But the transition from a company built around a handful of massive contracts to one with diversified, recurring revenue is a journey that has barely started.
Cerebras enters its post-IPO phase at a critical moment when the AI computing cycle is shifting from training toward inference — the part where speed directly determines commercial value, and where the company’s wafer-scale chip holds a genuine performance edge over competitors. Its chips generate tokens faster than most alternatives on the market, a technical advantage that matters more as AI models get deployed into real products.
Whether that advantage translates into sustainable margins is the question the market is now asking out loud. The first earnings report provided some answers. It raised just as many new ones.
