Cerebras is likely heading lower after terrible earnings, with share unlocks about to add supply. Its valuation was so stretched that it couldn't afford a miss, and it apparently missed; a lot of hope was already built into the price. It could trade around $150 soon. x.com  x.com  x.com  x.com 

Cerebras's share price already assumes years of flawless execution, so investors can be right about the company long term and still lose money. Two customers make up 86% of revenue, it posted a $146 million operating loss in 2025, its GAAP profit came from accounting gains, and it trades at 111x revenue. The wafer-scale technology, 15x faster AI inference and $20B+ OpenAI compute deal make the bull case real, but the price leaves no margin for early-stage setbacks. x.com 

Cerebras is a speculative, high-risk, high-reward bet on faster inference that could make its $44B market cap a multi-bagger if it works. Putting the whole processor and memory on one wafer wins on speed, not cheaper memory, since on-chip SRAM costs more per bit than HBM; Nvidia is answering via Groq. G42 and MBZUAI were 86% of 2025 revenue, but the ramp ahead is tied to OpenAI. The $160s level has held as support four times since the IPO. Size it to one's capital-preservation goals. x.com 

Cerebras faces brutal competition from SpaceX, and competing in AI models or data centers requires cash at scale. SpaceX is already trashing Cerebras and CoreWeave. x.com 

Cerebras is difficult for retail investors to understand, and management has not done a great job explaining its business since going public. It deserves more attention as the most direct AI IPO of 2026, but going long Cerebras is hard to justify when Nvidia can be owned instead. x.com 

Cerebras looks attractive because the short report's two-year wafer-life thesis rests on unvalidated reliability assumptions, not representative failure data. Energy per useful token, lower warranty utilization and ordinary repair accounting also undercut its financial conclusions. OpenAI has integrated Cerebras into production; AMD and AWS have announced integrations, while Oracle plans 2027 availability for ultra-fast inference, adding commercial validation despite the report. x.com  x.com 

Cerebras may lose demand as OpenAI appears to be shifting some workloads away from Nvidia and Cerebras. The concern is that Broadcom's Jalapeño chip is delivering stronger performance, potentially reducing demand for Cerebras, whose stock is back near 52-week lows. x.com 

Cerebras is a name to stay far away from. It tanked after OpenAI said its new chip with Broadcom outperforms Nvidia's, underlining how heavily Cerebras is tied to OpenAI, a dependence that hurt Oracle. It is also a recent IPO, a good share of its stock is owned by OpenAI insiders, and it is insanely volatile. x.com 

Vicor's efficient delivery of key power modules is part of the case for Cerebras meeting and exceeding its 2028-29 numbers. As models improve, more security breaches and deployments should make Cerebras look increasingly like a cybersecurity play. Its revenue ramp looks constrained by capacity, not yet by demand. Bullish on Cerebras but cautious on the broader market, with no short-term earnings prediction. x.com  x.com  x.com  x.com 

Cerebras still needs to come down further before it is worth buying. IPO stocks often rise sharply at first, then fall, and can take a long time to return to their original value, so entering at an expensive price right after the IPO is unappealing. The view is not entirely negative on Cerebras, and it should not be called a direct Nvidia rival. x.com
