Cerebras: Forgotten AI Chip Stock
Update - Oct. 8, 2026
Cerebras plummeted mid-day as confusing information surfaced regarding the revenue reported by key client OpenAI. Prior reports had suggested that ARR jumped to $70 billion despite sites like TickerTrends suggesting ARR was actually around $50 billion.

Now the market is viewing OpenAI revenue as slipping by $20 billion, but the reality is such a discrepancy in whether a site is reporting the gross ARR that includes payments to partners (Microsoft, AWS) or the new ARR. The financial picture of OpenAI isn't different.
Cerebras fell all the way to $161 on the news despite no impact to the $20+ billion deal with OpenAI. Apparently, the AI lab is already up to $55 billion in net ARR. The stock had fallen over $40 from the SemiAnalysis headlines to the OpenAI ARR drama, yet business is full-speed ahead.
