Cerebras Slides on Nvidia Snub, Then Rebounds on OpenAI Support

  • OpenAI picks Nvidia over Cerebras for GPT 6.1 Ultrafast A SemiAnalysis report said OpenAI's new GPT 6.1 Ultrafast runs on Nvidia chips, not Cerebras. That undercuts Cerebras's core pitch of fastest chips for high-value work and triggered a sharp selloff, with the stock down about 50% over the past month.

    This is the main new negative event that directly answers why CBRS moved.

  • OpenAI CEO calls Cerebras a close partner After the selloff, OpenAI CEO Sam Altman said Cerebras is a close partner with deep engagement pushing speed. The stock rebounded 8-10% on that reassurance, though the GPT 6.1 work still went to Nvidia.

    This is the key new positive counterweight that explains the bounce.

  • Jane Street buys up OpenAI-committed Cerebras compute Jane Street spent hundreds of millions to secure Cerebras compute that OpenAI had committed to its fast mode. While it shows demand for Cerebras chips, it also confirms OpenAI shifted that specific work to Nvidia, adding to investor worries.

    This new detail deepens the negative story and shows the demand shift.

  • Insider selling and lockup expiry add pressure The drop was compounded by the expiry of an early-investor lockup and stock sales by the CEO, CFO, and a COO sale of about $80 million just before the news broke. That signals possible lack of confidence and increases share supply.

    This new detail explains why the decline was so severe beyond the OpenAI news.

Q3 2026

Cerebras Grows Fast but Margins, Probe, Competition Bite

  • Explosive Revenue and Backlog Growth Revenue jumped 92% to $193.4 million, cloud revenue surged 287%, and backlog hit $25.4 billion, mostly from a $20 billion OpenAI deal. This shows demand is booming and future sales are locked in.

    This is the core positive force driving investor optimism and the stock's potential upside.

  • Margin Pressure and Revenue Miss Hardware sales fell 23%, causing a revenue miss, and gross margin guidance dropped to 38–41%. This means profits are shrinking, and the company is not selling as much of its main product as expected.

    This is a key negative factor that directly weighs on profitability and investor confidence.

  • Securities-Fraud Probe and Competitive Threats A securities-fraud probe tied to the IPO adds uncertainty, while Nvidia and Microsoft competition intensifies. A SemiAnalysis report claims Nvidia, not Cerebras, powers OpenAI's fastest tier, undercutting its speed advantage.

    These legal and competitive risks could damage reputation and market position, pressuring the stock.

  • Expansion and Partnerships vs. Widening Losses New partnerships with AMD and CrowdStrike, plus customers like Figma and GSK, broaden its base. Finland expansion boosts capacity but widens losses, pressuring near-term profits.

    This shows both growth initiatives and the cost of expansion, balancing positive and negative impacts.

    It shows Cerebras is diversifying its customer base and advancing its technology, a key growth driver.

  • Report says Nvidia, not Cerebras, powers OpenAI's fastest tier A SemiAnalysis report said OpenAI's GPT-6.1 Sol Ultrafast tier runs on Nvidia GPUs, not Cerebras chips. Shares fell 7%. This challenges Cerebras' key selling point—speed at low batch sizes—and raises doubts about its role in OpenAI's future infrastructure, hurting near-term confidence.

    It is a direct competitive threat that questions the durability of Cerebras' OpenAI relationship.

  • Finland data center expands capacity but losses persist Cerebras announced a 165 MW AI data center in Finland, with 600 MW secured for 2027. But core operating losses are widening, with Q3 guidance at negative 25–23% margin. The heavy spending to build capacity supports future growth but pressures near-term profits and cash flow.

    It highlights the trade-off between capacity expansion and ongoing losses, a key tension for the stock.
