Cerebras Rises 6.2% Premarket After Altman's Endorsement as Analysts Upgrade Ratings
nashnova research
OpenAI CEO Sam Altman publicly called Cerebras a "close partner," directly pushing back on fears that Nvidia is replacing it — Cerebras rose 6.2% pre-market, but whether this endorsement converts into real business hinges on one thing: capacity expansion.
What exactly did Altman say?
Altman posted on X Friday evening, calling Cerebras a "close partner" of OpenAI with "deep collaboration" on the "speed frontier."
This means → The top executive at OpenAI stepped in personally — a stronger signal than any contract announcement.
Cerebras traded at $176.69 pre-market Monday, up 6.2%, after five straight sessions of losses totaling 15%.
What was the market worried about?
Semiconductor research firm SemiAnalysis had revealed that OpenAI's latest GPT-6.1 Sol model powers its "Ultrafast" mode using Nvidia chips, not Cerebras hardware.
In plain terms = The fear was simple — Cerebras's largest customer might be handing its core workload to a direct competitor.
OpenAI is Cerebras's largest customer by revenue backlog — contracted but undelivered orders. Losing that relationship would strike at the company's foundation.
How much does Altman's statement actually resolve?
Altman's wording implies Cerebras could still supply compute for "Ultrafast" mode — likely after its chip capacity expansion is complete.
This means → The partnership isn't dead, but Cerebras must fix its supply bottleneck before it earns back a seat at the table.
This reflects a deeper signal: OpenAI's compute strategy is "whoever can deliver first gets the job." Loyalty takes a back seat to execution.
Why did the analyst upgrade now?
Paul Meeks, head of technology research at Freedom Capital Markets, upgraded Cerebras from hold to buy on Friday, calling the sell-off overdone.
His core thesis: "Watch the real targets — timely completion of power-capacity expansion, and entering after most execution risk is digested."
In plain terms = He isn't saying the risks are gone. He's saying the stock has already priced in the worst case, making it a worthwhile bet on capacity landing on time.
Where does Cerebras stand now?
Cerebras completed its IPO in May at an opening price of $350. The stock now trades at $176.69 — roughly half that level.
Early enthusiasm for its wafer-scale AI chip — a single chip built from an entire silicon wafer, optimized for running models at high speed — has faded as earnings fell short of expectations.
This means → The next catalyst is singular: can the capacity expansion land on time and on budget? That determines whether this is a turning point or a continued slide.
