Culper Research's wafer-failure complaints do not justify shorting Cerebras at $100. The customer complaints sound illogical, although quality issues would not be surprising while the chips are in the early-adopter phase. x.com  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 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 be the only company willing to stitch together a true high-speed solution. If so, it retains upside optionality from high-speed pricing and gains a first-mover advantage. 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 

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' 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 dud that looks set for new lows. It went public into a red-hot semiconductor sector and still failed, and with semiconductors now rolling over, it looks poised to break major support. x.com 

Cerebras's post-earnings selloff reflects an inability to deliver fast enough yet, not weak demand, a setup like an early Nebius. Its hardware IP delivers the most efficient inference on the market and already draws massive demand from Amazon and OpenAI, on the conviction that inference becomes AI's main demand source and speed the differentiator. What it lacks is infrastructure to scale hardware production and cloud capacity. The open question is whether it can execute as Nebius did. x.com
