Key takeaways
- Cerebras stock surges 17% following stronger earnings and guidance
- Microsoft joins Cerebras as AI cloud revenue jumps 272%
- $26.1 billion backlog highlights growth potential and execution risks
Cerebras Systems (NASDAQ: CBRS) shares surged more than 17% in extended trading on November 12 after the artificial intelligence chipmaker announced a Microsoft cloud agreement, raised its annual revenue forecast and disclosed $26.1 billion in remaining performance obligations.
The rally followed a difficult period for AI stocks, with Nvidia's leadership crisis raising questions about the industry's future. Cerebras' results suggest demand for alternative AI computing technology remains strong despite broader market uncertainty.
Cerebras Revenue Jumps 70% as Microsoft Joins AI Cloud Customers
According to the company's November 12 earnings release, third-quarter core revenue reached $230.9 million, a 70% increase from a year earlier.
Core cloud and services revenue surged 272% to $144.9 million, reflecting rapidly growing demand for high-speed AI inference.
Reported GAAP revenue was lower at $210.8 million, while the company recorded a $161.2 million net loss. The difference between reported and core results reflects adjustments including customer warrants and certain data-center costs.
Microsoft emerged as a new hyperscale customer, joining Cerebras' expanding network of enterprise and cloud partnerships.
The agreement creates another potential competitor to Nvidia's GPU-based ecosystem, although Cerebras has not disclosed the Microsoft contract's financial value.
The development comes as AMD and Broadcom gain momentum in alternative AI hardware.
Cerebras differentiates itself through wafer-scale processors designed for high-speed inference, particularly applications requiring rapid responses from large AI models.
Cerebras' $26.1B Backlog Is Largely Tied to OpenAI
Cerebras reported $26.1 billion in remaining performance obligations as of September 30, up from approximately $25.4 billion in the previous quarter.
A significant portion relates to its long-term OpenAI computing agreement, which includes committed infrastructure capacity and related services.
However, backlog is not cash already received or revenue already recognized. Some obligations also incorporate estimated data-center pass-through costs, making the figure different from future operating profit.
The distinction matters because AI infrastructure financing increasingly depends on long-term customer commitments supporting substantial upfront investment.
Cerebras has secured 700 megawatts of gross data-center capacity for delivery by the end of 2027, while expanding manufacturing through Flex and Sanmina.
Its Oracle partnership will also bring Cerebras-powered inference to Oracle Cloud Infrastructure in 2027, providing another route to enterprise customers.
The expansion resembles the aggressive capacity-building strategies pursued by Nebius and CoreWeave, where strong demand must justify substantial infrastructure spending.
Cerebras Raises 2026 Outlook as Nvidia Competition Intensifies
Cerebras raised its full-year core revenue forecast to $940 million–$960 million from its previous $880 million–$890 million range.
For the fourth quarter, management expects core revenue of $310 million–$330 million and a core operating margin between negative 1% and positive 1%.
CEO Andrew Feldman also said the company expects revenue to triple in 2027, although execution will depend on computing capacity becoming available.
That uncertainty has already affected competitors. Nebius recently cut its outlook after construction delays pushed expected capacity into 2027.
Cerebras' growth also arrives as AI stock valuations face increasing scrutiny over profitability and financing costs.
