Nvidia took the business that Cerebras wanted most. Cerebras’ stock price is down about 20% this week, reaching its lowest point since going public (CNBC).
​
The trigger was a report from SemiAnalysis: OpenAI’s new GPT-6.1 Sol “Ultrafast” mode, which claims to be 8 times faster than the standard version, runs on Nvidia GPUs and uses small-batch inference—not Cerebras’ wafer-scale chips.
​
That lands right on Cerebras’ selling point: its chips are specifically designed for “low-batch, low-latency” inference.
​
In January this year, it reportedly signed a compute power deal with OpenAI worth about $10 billion.
​
In the same week, the post-listing lockup period ended, and about 19.4 million shares held by insiders could be sold—about 8% of the total shares outstanding.
​
Reportedly, Cerebras closed Friday at $166.43, more than half below its closing price from its first day of trading after listing in May.
​
Binance’s bStocks also has a tokenized version called CBRSB.
​
The moat for AI chips may be shallower than what the valuation suggests. When it comes to inference, do you think Nvidia will ultimately take the whole market?
