Cerebras is wildly overvalued after opening its debut up 102%, at about 157.8x sales. FY25 revenue was $510M against 215.23M shares outstanding, and its $150M net income was not related to its core business. Late buyers risk becoming bag holders. x.com  x.com 

Cerebras is absurdly valued at about $50 billion against roughly $865 million of full-year revenue and $194 million for the quarter. Overpriced listings like this will hurt young investors and push them to give up on stock investing. 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 is not worth owning at about $90 billion in value on roughly $500 million of revenue. A post the author replies to adds that it has only two customers and argues investment banks are using retail investors for exit liquidity. x.com 

Cerebras is unattractive to buy at a valuation above $60 billion while its product remains unproven at scale. x.com 

Cerebras' inference opportunity can support substantial long-term upside if installed capacity grows from 60MW to 3.2GW by 2031 and OpenAI renews after 2028. The risk-adjusted model puts 2031 value at $485-$700 per share while assuming rivals narrow its speed premium and customers and partners fund most capex. If those assumptions fail, capex, dilution and valuation risk rise. x.com 

Cerebras is a stock to avoid in a cash-out environment where companies, executives, employees and early investors are selling to buyers. Per a WSJ report cited by @wallstengine, Nvidia's AI chip business is over 400x larger than Cerebras and growing nearly as fast, yet Cerebras trades around 134x trailing revenue, more than 5x Nvidia's multiple. 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 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 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
