Cerebras beats revenue expectations and lands Microsoft deal

Cerebras Systems reported quarterly revenue and guidance on Thursday that came in better than Wall Street expected. It also announced a new deal with Microsoft.

Investors responded quickly. The stock rose 12% in extended trading, according to CNBC, which is a notable move for a company that is still posting a loss.

The numbers behind the jump

For the third quarter of 2026, Cerebras reported GAAP revenue of $210.8 million. That is up 55% from the same quarter a year earlier.

The company also reports a separate figure it calls core revenue, which reached $230.9 million. Inside that number, core cloud revenue was $144.9 million, an increase of 272% year over year.

On profitability, the company posted a loss of 67 cents per share. The revenue beat clearly mattered more to investors than the loss line.

Management also raised its outlook. Full-year 2026 core revenue guidance now sits between $940 million and $960 million.

Microsoft, Oracle, and a very large backlog

The Microsoft announcement drew the attention. Microsoft is one of the hyperscalers, the small group of cloud giants that buy computing capacity in enormous volumes. The company described its new commercial partnerships with these hyperscalers as including Microsoft.

Microsoft is not the only big name on the list. Cerebras also announced a partnership with Oracle Cloud Infrastructure that takes effect in 2027.

Smaller deals are also coming in. Cerebras disclosed a commercial win with Bilt in November 2026.

The figure that may matter most over the long run is remaining performance obligations. As of September 30, 2026, that number stood at $26.1 billion.

That delivery depends on physical capacity. The company said data-center capacity under contract has grown to 700 megawatts.

What Cerebras actually sells

Cerebras focuses on wafer-scale AI inference. Inference is the stage of AI where a trained model does its job: answering a prompt, summarizing a document, or producing code. Training builds the model, and inference is how people use it every day.

Wafer-scale describes the company’s hardware approach. Cerebras builds processors on the scale of an entire silicon wafer instead of cutting that wafer into many smaller chips.

What this means for investors and the AI buildout

For shareholders, the quarter answers an important question for any high-growth infrastructure company: is demand real, and is it lasting? A 55% increase in GAAP revenue, a raised forecast, and a backlog in the tens of billions point toward yes.

Cerebras posted a loss of 67 cents per share, so the company is still investing heavily to grow.

Converting the backlog is the main thing to watch. Signing $26.1 billion in obligations is one milestone. Building out 700 megawatts of contracted capacity and delivering against those contracts on schedule is a harder one.

The timing of the Oracle partnership matters too. Because it begins in 2027, its financial contribution will appear in future quarters, not current results.
