Cerebras Stock Hits Post-IPO Low Amid Nvidia Pressure and Insider Selling

Cerebras Systems Inc. stock fell nearly 20% this week, reaching its lowest price since the company's initial public offering in May. The downturn is driven by reports that chip giant Nvidia will power a crucial component of OpenAI's latest AI model, alongside the expiration of post-IPO restrictions on insider share sales.

According to research firm SemiAnalysis, OpenAI intends to utilize Nvidia's graphics processing units (GPUs) for the "Ultrafast" mode of its GPT-6.1 Sol model, bypassing Cerebras's hardware. This marks a significant setback for Cerebras, whose stock has now declined by more than half from its initial surge following its market debut.

The stock also faced pressure from the release of insider shares into the market as the company's lock-up period expired. Cerebras shares closed at $166.43 on Friday. The company's market capitalization has significantly decreased, now standing at just over $39 billion, down from nearly $95 billion on its first day of trading.

Cerebras develops large, custom-designed artificial intelligence chips and offers them as a cloud service from its data centers. In January, the company secured a deal worth over $10 billion with OpenAI to supply 750 megawatts of computing power through 2028. With inference workloads projected to surpass training as the dominant AI workload in data centers, investors had initially anticipated Cerebras's strong position in this sector.

The company's stock performance has reversed substantially from its initial post-IPO valuation. Cerebras's future success will depend on its ability to compete with major players like Nvidia and secure substantial client agreements moving forward.
