Cerebras Systems Inc rose 15.88% to $253.76 on Monday as investors reassessed last week's sharp post-earnings selloff and focused on fresh details tying the company more closely to OpenAI's latest high-speed inference offering. Wedbush said Cerebras is the exclusive compute backbone for the newly launched GPT-5.6 Sol Ultrafast mode, which delivers up to 750 output tokens per second, about 14 times faster than standard processing, using the company's Wafer-Scale Engine. Wedbush raised its price target to $290 from $280 while maintaining a bullish stance, and pointed to OpenAI's commitment to purchase 750 megawatts of Cerebras capacity by 2028, a key support for the company's $25.4 billion in remaining performance obligations. The stock's rebound followed a roughly 17% drop on August 13 after headline second-quarter revenue of $180.11 million missed consensus, even as core revenue reached $209.9 million, up 103% year over year, core cloud and services revenue climbed 287%, and management raised fiscal 2026 core revenue guidance to $880 million to $890 million while reiterating plans to more than triple core revenue in 2027. CEO Andrew Feldman said faster inference can improve user engagement, agentic performance and AI productivity by enabling new applications. New 13F disclosures also kept attention on positioning in AI-linked chip names: NVIDIA, SoftBank Group and Coatue Management reported large Intel holdings; Tiger Global Management and Duquesne Family Office disclosed new AMD positions; and Atreides Management reported 3,110,086 Cerebras shares valued at $687,329,006. Cerebras' next catalyst is its planned fourth-generation system unveiling at the Supernova Conference in the week of August 19, 2026.
