Cerebras Stock Falls to Post-IPO Low Amid Nvidia Competition and Lockup Expiration

Cerebras shares dropped nearly 20% this week, reaching their lowest point since the company's IPO in May. The decline follows Nvidia's announcement of its partnership with OpenAI, coupled with the expiration of lockup restrictions on insider shares.

Stock Plummets

Cerebras stock fell sharply this week, declining nearly 20% and closing at $166.43. This drop marks the lowest price since its initial public offering (IPO) in May, which initially saw the stock soar. The decline is primarily attributed to increasing competition from Nvidia, which is set to power a key feature of OpenAI's GPT-6.1 Sol model with its graphics processing units, rather than Cerebras hardware.

Market Pressure from Nvidia

According to a report by SemiAnalysis shared on X, the decision to utilize Nvidia hardware has significantly impacted Cerebras. The company's market capitalization has dropped from nearly $95 billion at the time of its IPO to just over $39 billion now, reflecting concerns about losing its competitive edge in the AI hardware market.

Lockup Expiration's Effects

Additionally, the stock faced pressure from the expiration of lockup restrictions on insider shares. On Wednesday, approximately 19.4 million shares held by directors and executives were made available for sale, amounting to 8% of total shares outstanding. This follows earlier unlocks of 14.6 million shares that occurred every two weeks since August 19.

Responses and Future Outlook

Despite the downturn, Cerebras experienced a slight recovery, gaining almost 3% in after-hours trading after OpenAI CEO Sam Altman reaffirmed the partnership with Cerebras, emphasizing their ongoing collaboration. Nevertheless, the loss of OpenAI's inference workload to Nvidia poses significant challenges for Cerebras moving forward. Investors are left to navigate the turbulent landscape as more shares enter the market over time.
