Cerebras Earnings Beat as Microsoft Deal Lifts Shares 18%

In a press release dated Nov. 12, 2026, Cerebras Systems reported results for the third quarter ended Sept. 30, 2026, with GAAP total revenue of $210.8 million and core revenue of $230.9 million. Cerebras earnings topped the LSEG consensus of $214.7 million for core revenue, according to CNBC's Jordan Novet on Nov. 12, while the company guided Q4 2026 core revenue to $310 million to $330 million.

Core revenue is a non-GAAP measure that excludes non-cash amortization of customer warrants, stock-based compensation, data center pass-through revenue and costs, and certain other items. Shares rose about 18% in extended trading after the report, CNBC said, though the stock had fallen about 47% since Cerebras' Nasdaq debut in May 2026.

What did Cerebras earnings show for Q3 2026?

Cerebras reported record GAAP total revenue of $210.8 million, up 55% year over year. GAAP cloud and other services revenue reached $141.9 million, up 265%, while GAAP gross margin was 20% and GAAP operating margin was -106%.

On a core basis, total revenue rose 70% year over year to $230.9 million, from $135.7 million cited by CNBC. Core cloud and other services revenue climbed 272% to $144.9 million, core gross margin was 41%, and core operating margin was -14%.

AP reported a net loss of $161.2 million for the quarter. CNBC said loss per share was 67 cents, adding that it was unclear how that compared with the 14-cent loss expected by analysts.

What is the Microsoft deal?

Cerebras said in its Nov. 12 press release that it had announced an important cloud deal with a top-three hyperscaler, with more details to be shared next year. A hyperscaler is a large cloud infrastructure provider that operates data centers at global scale.

CEO Andrew Feldman told CNBC the deal is with Microsoft, was signed in October 2026, and that the company believes revenue begins to show up in Q1 2027. CNBC also said Cerebras has deals with Amazon and Oracle, while the company said Cerebras will be available in Oracle Cloud Infrastructure in 2027.

Cerebras also announced commercial wins with two new hyperscalers. Bilt Neighborhood OS and Bilt Concierge AI will use Cerebras inference across a network that includes 8 million consumers and 50,000 businesses.

What is Cerebras guiding for Q4 and 2027?

After the Cerebras earnings beat, the company guided Q4 2026 core revenue to about $310 million to $330 million, above the $271 million LSEG estimate. The company expects Q4 core gross margin of 47% to 49%, compared with an estimate of 42.1%, and core operating margin of -1% to 1%.

For the full year 2026, Cerebras raised its outlook to $940 million to $960 million in core revenue, 42% to 44% core gross margin, and -10% to -8% core operating margin. Feldman said the company expects to triple revenue in 2027, which CNBC said implies about $2.85 billion versus LSEG analyst expectations of $2.92 billion.

Remaining performance obligations, meaning contracted business not yet recognized as revenue, stood at $26.1 billion as of Sept. 30, 2026. Cerebras also reported $7.8 billion in cash, equivalents, restricted cash and short-term investments, plus $850 million of debt capacity.

Why does this matter in the race with Nvidia?

The report arrived the same day CNBC reported that Nvidia CEO Jensen Huang resigned, a move that briefly sent Nvidia stock down 14%, adding broader market attention to the AI infrastructure race. Feldman told CNBC that long GPU lead times and higher hardware expense create an opportunity for Cerebras, particularly in hardware sales. Cerebras sells one giant wafer-scale chip per system, a different bet from the GPU and custom accelerator split we covered in TPU vs GPU.

Cerebras said it has secured 700 gross megawatts of data center capacity for delivery by the end of 2027, including new contracts in Norway and Finland. The company also said it expects to exit 2026 with more than 10x manufacturing capacity compared with the start of the year, through manufacturing partners Flex and Sanmina.

On products, Cerebras claims the first production-scale heterogeneous disaggregated inference, meaning inference stages are split across different hardware to improve throughput. The company says the approach can deliver up to 5x more tokens per data center. CS-4, introduced at Supernova 2026, will soon be in full production, while CS-5 is targeted for early summer 2027 and is designed for up to 10,000 tokens per second per user.

Our take: These Cerebras earnings show powerful AI cloud momentum, but growth is decelerating from 103% in Q2 to 70% in Q3 even as cloud revenue explodes. GAAP operating margin remains deeply negative at -106%. Still, adding a top-three hyperscaler reduces customer concentration risk, and inference speed could matter if Nvidia GPU supply remains tight or costly. The real test is whether Cerebras can keep winning cloud contracts as rivals such as AMD, whose latest earnings also leaned on data center demand, push their own accelerators.
