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 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 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' 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 and its customers likely accounted for many of the chip limitations alleged in the short report, so the report may be wrong. This is a suspicion without specific insight. Short interest rose 40.7% into the report to 19.86 million shares, or 8.4% of float. x.com  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 should dominate the enormous fast-inference market because agentic workflows often run steps sequentially, making each step's speed critical. Its newly announced Oracle partnership brings its ultra-fast inference to Oracle Cloud Infrastructure. Cerebras delivers inference speeds up to 13x faster than Nvidia GPUs, and its chips should eventually reach every major AI cloud. x.com 

Cerebras is now worth buying after its shares fell into the previously stated $60-$120 buying range. The earlier concern was an out-of-control valuation and providing liquidity to insiders at much higher prices; the shares shown are about $117. x.com 

Cerebras is an unattractive stock to hold now, even though ultrafast speed is a feature companies would happily pay for. Controversy over OpenAI's ultrafast running on Nvidia chips, the share lockup expiration and insider selling outweigh the chance that OpenAI's next 6.1 Sol ultrafast actually runs on Cerebras chips. x.com 

Cerebras has a clear use case in hyperfast inference that customers will pay a premium for, per an expert call with a Figma director. Figma routes about 40% of its AI assistant traffic to Cerebras' cloud, which ran 10-15x faster than most rivals in its tests, and he would pay a 50% to 2x premium for that speed. Spend, now in the low-to-mid seven figures, could double or triple within one to two years. Reserved capacity, reliability, observability and slow deployment limit its share. x.com
