Cerebras beats and raises outlook — stock plunges 12% anyway
Chip earnings split the day's AI news: Cerebras beat and raised, then watched investors head for the exits — while the money behind the compute buildout quietly got itself a benchmark layer.
Cerebras reported second-quarter core revenue of $210 million, ahead of the $194 million it had guided to, raised its full-year outlook to $880–890 million — and still saw its stock plunge about 12 percent in extended trading. In the chipmaker's second earnings report since its May IPO, the market reaction says a lot about what's already priced into the wafer-scale story: a beat plus a raise wasn't enough, with a $2.89 per-share loss and the gap between core revenue and the $180.1 million GAAP figure giving investors pause. The margin drag is temporary — Cerebras has been renting back systems from an existing customer while its own data centers come online — but it's visible now, in the quarter.
CEO Andrew Feldman said AI demand is "through the roof" and that gross margins are growing because fast inference commands a premium; the company expects core gross margin to expand to 38–40 percent this quarter and sees revenue tripling next fiscal year. Cerebras also disclosed $25.4 billion in remaining performance obligations, the backlog it cites as evidence of "extraordinary future demand," with its cloud pulling in $126 million in the June quarter. The takeaway: demand is real, but so is the cost of scaling fast — and investors are now judging this stock on the second number.
Silicon Data raised $30.5 million in an initial Series A close, led by the Valor Atreides AI Fund with participation from CME Group, DRW, F-Prime, Samsung and VanEck, to build what it calls the independent benchmark layer for the AI compute economy. The New York startup publishes nine financial-grade indices tracking GPU and LLM pricing, supply and utilization — and CME plans to use its benchmarks as the reference price for a planned cash-settled GPU futures market, pending regulatory approval. Part of the round funds SiliconMark, which measures how physical GPU infrastructure actually performs: two clusters on identical chips can deliver very different output depending on networking and configuration. It's a bet that compute is becoming a commodity market — and that commodity markets need referees before they need traders.
What to watch: whether Cerebras' margin recovery shows up next quarter — and whether CME's GPU futures clear regulatory approval.
