An OpenAI Deal Could Be a Game Changer for Cerebras Stock After a Brutal Selloff

Cerebras Systems (CBRS) stock took a brutal hit after the company’s Q2 earnings report, but investors may be missing the bigger picture. Shares plunged roughly 12% in Thursday trading after the AI chipmaker reported a revenue miss and a massive net loss. Yet underneath those headline numbers, the business is growing at an extraordinary pace.

Core revenue more than doubled, cloud revenue nearly quadrupled, and management raised its full-year outlook. Then came an even bigger catalyst. Cerebras said it is powering a new ultrafast tier for OpenAI’s GPT-5.6 Sol. However, this news failed to lift the stock, and shares plunged more than 5% on Friday. The bulls brought CBRS stock back up 15% Monday just for the price to tank over 12% again during morning trading today.

The question now is whether the earnings-driven selloff creates an attractive entry point or exposes more profound problems.

Cerebras Stock Has Taken a Beating

Cerebras shares have been extremely volatile since their May 2026 IPO. CBRS stock reached a 52-week high of $386 on May 14 before falling to a 52-week low of $160.8 on June 26. Leaving the stock down more than 25% in the last three months. The latest pressure came after the company’s Q2 earnings release, when investors focused on the GAAP revenue shortfall and enormous net loss.

Competition is another concern. Nvidia (NVDA) remains the dominant force in AI accelerators, while AMD (AMD) and a growing number of specialized chip companies are fighting for a share of the rapidly expanding market. That makes Cerebras’ ability to turn technological differentiation into sustainable revenue particularly important.

Valuation Leaves Little Room for Error

Cerebras is not a traditional value stock. Its trailing price-to-earnings (P/E) ratio is around 506.48, while its price-to-sales (P/S) ratio stands near 81.97. Those figures look extremely expensive compared with the semiconductor industry.

However, investors are paying for future growth rather than current earnings. The forward P/S ratio is considerably lower at roughly 36, while the company has reported $25.4 billion in remaining performance obligations.

That backlog is important because it provides visibility into future demand. Still, Cerebras must execute. A premium valuation can remain justified only if revenue growth continues at an exceptional pace and the company gradually improves profitability.

OpenAI Partnership Could Change the Narrative

The biggest development came just one day after earnings.

Cerebras announced that its technology is powering Ultrafast mode for OpenAI’s GPT-5.6 Sol through the OpenAI API. The service can reportedly deliver up to 750 output tokens per second, offering dramatically faster inference than standard processing.

That is potentially significant for Cerebras because it places its wafer-scale technology directly into a high-profile AI workload. Faster inference can be valuable for applications where response speed is critical, including real-time AI agents and interactive software.

For investors, the OpenAI relationship could provide something Cerebras desperately needs: validation. The company is trying to prove that its architecture can compete with established AI chip giants, and a major OpenAI deployment strengthens that argument.

Q2 Results Reveal Strong Underlying Growth

The headline Q2 numbers were messy. Total Revenue came in at $180.1 million, below the $194.2 million consensus estimate.

But core revenue told a different story.

Cerebras generated $210 million in core revenue, representing 103% year-over-year (YoY) growth. Core cloud and other services revenue jumped 287% to $127.7 million, while core hardware revenue increased 17% to $82.1 million.

The cloud business is clearly becoming the company’s growth engine.

The GAAP net loss was $450.5 million, compared with net income of $309.5 million a year earlier. However, $386.6 million of the loss came from stock-based compensation. Adjusted EPS showed a loss of just $0.05, better than the $0.17 loss analysts expected.

Cerebras ended the quarter with more than $8.6 billion in cash, restricted cash, and marketable securities. Management also raised full-year 2026 core revenue guidance to $880 million-$890 million from $855 million-$865 million.

For Q3, Cerebras expects core revenue of $214 million-$216 million, above the $212.6 million analyst consensus. Core gross-margin guidance was also raised to 41%-43%.

What Wall Street Thinks of CBRS Stock

Despite the selloff, analysts remain bullish on Cerebras. According to 11 analysts polled by Barchart, the stock has a consensus “Strong Buy” rating.

The average price target stands at $283.91, implying roughly 29% upside from the current price.

Morgan Stanley maintained an “Overweight” rating and raised its target to $279 from $273. Wedbush kept an “Outperform” rating and lifted its target to $290 from $280. UBS also maintained a “Buy” rating while raising its target to $330 from $320.

Citi remains bullish with a “Buy” rating despite cutting its target to $320 from $340, while Mizuho maintained “Outperform” and lowered its target to $300 from $310.

With targets ranging from $209 to $330, Wall Street clearly sees risks. But the overall consensus remains constructive, suggesting the latest selloff may be viewed as an opportunity rather than the beginning of a fundamental breakdown.
