Cerebras Systems (CSAI) Stock: Should You Buy After the Post-IPO Sell-Off?

TLDR

• Cerebras Q1 2026 revenue hit $193.4M, up 94% year-over-year
• A $20B+ multiyear deal with OpenAI to deploy 750MW of inference capacity is a major vote of confidence
• Amazon partnership brings Cerebras inference to AWS customers
• Full-year 2026 core revenue guidance is $855M–$865M, roughly 69% growth
• Gross margins of 38%–41% trail Nvidia’s mid-70s, and the company is still operating at a loss

Cerebras Systems went public as one of the most watched AI chip listings in recent memory. The stock has pulled back from its post-IPO high, and now investors are asking whether that dip is a buying opportunity or a warning sign.

Cerebras Systems Inc., CBRS

Here is what the numbers say.

Cerebras reported Q1 2026 revenue of $193.4 million, a 94% jump from the same period last year. Hardware revenue rose 59% to $110.6 million. Cloud and services revenue grew even faster, up 178% to $82.8 million.

The cloud segment matters. Recurring compute revenue is a more scalable model than selling chips one at a time, and its growth rate suggests customers are leaning into the platform.

Management has guided full-year core revenue between $855 million and $865 million, representing around 69% growth at the midpoint. That is a strong number for a company that only recently started trading publicly.

The OpenAI Deal

The headline partnership is a multiyear agreement with OpenAI worth more than $20 billion. Under the deal, OpenAI will deploy 750 megawatts of Cerebras inference capacity over several years.

That is a serious commercial commitment from one of the most prominent names in AI.

Cerebras has also partnered with Amazon to offer its inference services through AWS. That gives the company a distribution channel into a broad base of startups and enterprises without having to land every customer deal on its own.

The risk that comes with these wins is concentration. A large portion of Cerebras’s near-term future depends on a handful of customers following through on very large commitments.

Margins and Losses Still a Factor

Cerebras is not profitable. The company posted a $14 million GAAP net loss in Q1 2026 and expects adjusted operating margins between negative 28% and negative 32% for the full year.

Adjusted gross margins are projected at 38%–41% for 2026. That is well below Nvidia’s mid-70% range and AMD’s mid-50s. Wafer-scale chips are technically demanding to manufacture, and building out data center infrastructure takes significant capital.

The company has raised billions through its IPO and additional financing, so it has runway to execute. But investors should expect losses to continue for a while.

Wall Street is cautiously optimistic. MarketBeat shows a Moderate Buy consensus across 12 analysts, with one Strong Buy, nine Buys, and two Holds. The average 12-month price target sits at $299.30, ranging from $273 to $340.

Because Cerebras is newly public, analyst estimates are likely to shift as more quarterly data comes in.

The most recent data point: Q1 2026 revenue of $193.4 million came in strong, and the company maintained its full-year guidance of $855M–$865M.
