Cerebras Reports Record Q3 Revenue and Raises Its 2026 Outlook

Cerebras Q3 results, published on 12 November 2026, show record GAAP revenue of $210.8 million for the third quarter ended 30 September, up 55% from a year earlier, and a raised full-year outlook on a non-GAAP “core” basis. The figures are in the company’s press release and were furnished to the US Securities and Exchange Commission the same day as Exhibit 99.1 to a Form 8-K.

The same release also contained a customer announcement that the written statement left unnamed. “Today, Cerebras announced an important cloud deal with a top three hyperscaler. More will be shared next year,” the company said. On the earnings call, and in a separate interview, chief executive Andrew Feldman named that customer as Microsoft. Microsoft has not commented. No deal size, capacity or duration was disclosed.

What the Cerebras Q3 results put on the record

Cerebras asks readers to hold two sets of numbers at once. The GAAP line is the one required by US accounting rules. Core results, which the company labels as non-GAAP, “exclude the impacts of non-cash amortization of customer warrants and stock-based compensation, data center pass-through revenues and costs, and certain other items.”

On a GAAP basis, cloud and other services revenue was a record $141.9 million, up 265% year-on-year. Gross margin was 20%, described as up sequentially. The GAAP operating margin was a loss of 106%. On the core, non-GAAP basis, total revenue was $230.9 million, up 70% year-on-year; core cloud and other services revenue was $144.9 million, up 272%; core gross margin was 41%, up both sequentially and year-on-year; and the core operating margin was a loss of 14%.

The company raised its core, non-GAAP outlook. For the fourth quarter of 2026 it points to core revenue of approximately $310 million to $330 million, core gross margin of 47% to 49%, and a core operating margin between a 1% loss and a 1% profit. For the full year it now expects core revenue of $940 million to $960 million, core gross margin of 42% to 44%, and a core operating margin between a 10% and an 8% loss. Those forward figures are themselves non-GAAP, and the release says no reconciliation to a GAAP equivalent is provided because the company “cannot reliably predict all necessary components” without unreasonable effort.

Three stock figures sit beside the income statement. Cerebras said it now has “700 megawatts of data center capacity now under contract,” and, later in the same release, that it has “secured 700 gross megawatts of data center capacity for delivery by the end of 2027.” Remaining performance obligations were $26.1 billion as of 30 September 2026. Liquidity was given as cash, cash equivalents, restricted cash and short-term investments of $7.8 billion, with debt capacity of $850 million.

The $26.1 billion backlog needs a caveat from the company’s own quarterly report. In its Form 10-Q for the period ended 30 September 2026, Cerebras says remaining performance obligations “include estimates of variable consideration, including pass-through costs, and are subject to change as those estimates are updated,” and that “a significant amount of the balance was attributable to the Company’s obligations pursuant to the MRA with OpenAI.” That OpenAI master relationship agreement, described in the same filing, is a commitment by OpenAI to purchase 750 megawatts of AI inference capacity and related services, with an option for further capacity. The 10-Q says the company expects to recognise about 33% of the $26.1 billion over the 24 months ending 30 September 2028, 44% between months 25 and 48, and the remainder after that, with timing subject to change.

Cerebras also said it will be available in Oracle Cloud Infrastructure in 2027. That is a company statement about a named cloud, with a year attached and no contract value in the release. Amazon Web Services appears only as context from Feldman: he told CNBC that Cerebras has also landed deals with Amazon and Oracle.

Feldman named Microsoft; the release did not

The written release’s wording is the one that will still be on the page after the call has faded: a cloud deal with “a top three hyperscaler,” with more to be shared next year. Feldman went further. In the CNBC interview, published on 12 November 2026, he said executives would announce a new relationship with Microsoft on the call, that “we believe revenue begins to show up in Q1 ’27,” and, CNBC reported, that Microsoft signed the deal in October.

Those are Feldman’s statements, not Microsoft’s. TSN has not seen a comment from Microsoft on the agreement, and neither the release nor Feldman disclosed a price, a megawatt commitment or a term. The right way to hold the point is as a named customer, attributed to the chief executive, with the commercial terms still unknown and further detail promised in 2027.

The same caution applies to the growth claim that will travel with the results. In the release, Feldman said the company would “expect to triple revenue in 2027.” That is a company expectation, not a completed booking and not a figure the 8-K presents as guidance in the same formal sense as the 2026 core ranges.

Cerebras has turned up in TSN’s pages before as the chip underneath other people’s clouds, rather than as the company reporting its own accounts. When General Compute raised $100 million to run AI on Cerebras and SambaNova chips, the story was a neocloud betting on those accelerators. The Oracle date in this release also sits beside other accelerators already scheduled for that cloud, including Google’s TPUs, which are due on Oracle Cloud from 2027, and NVIDIA’s Vera Rubin systems on the same platform. Those comparisons are about who else will be for sale in the same shop, not evidence that any of the deals are the same size.

A named customer is not a disclosed contract

The temptation, with a record quarter, a raised outlook, a $26.1 billion remaining-performance-obligation figure and the word “Microsoft” on an earnings call, is to flatten all of it into a single story about demand. The documents stop short of doing that work for the reader.

First, core revenue is a managed number. It is useful, and Cerebras says it is how management looks at the business, but it is not a substitute for the GAAP result, which in this quarter still shows a wide operating loss. The company’s own warning that the 2026 and fourth-quarter core outlooks have no GAAP reconciliation is part of the result, not a footnote to skip.

Second, remaining performance obligations are not cash in the bank, and they are not evenly spread. The 10-Q ties a significant share of the $26.1 billion to the OpenAI agreement, includes estimates of variable pass-through costs, and spreads recognition over several years, with delivery timing able to move. The $7.8 billion of cash and short-term investments is a different fact: it is what the company held, not what it has still to earn. The 700 megawatts of data-centre capacity “under contract” and “for delivery by the end of 2027” is a third fact again — contracted power and space, not revenue already recognised.

Third, the Microsoft announcement is unfinished on purpose. The release withheld the name; Feldman supplied it; the terms are reserved for next year; Microsoft has not added its own account. A reader can record that Cerebras says it has a cloud deal with Microsoft, expected, by its chief executive, to begin producing revenue in the first quarter of 2027, and still treat the value of that deal as unknown. Nothing in the 8-K or the 10-Q fills that gap.

The near checkpoint is therefore the one the company has actually quantified. The fourth-quarter core range of $310 million to $330 million is the next published test of whether the raised 2026 outlook is being earned in the accounts. What remains to be seen in 2027 is the promised detail on the Microsoft deal, and how much of the OpenAI-heavy backlog is recognised on the timetable the 10-Q now sketches.

How we sourced this

The financial figures, the core-versus-GAAP definitions, the outlook ranges, the 700-megawatt capacity, the $26.1 billion of remaining performance obligations, the $7.8 billion of cash and the wording “a top three hyperscaler” come from the 12 November 2026 press release and the 8-K exhibit. The concentration of remaining performance obligations on the OpenAI agreement comes from the 10-Q for the quarter ended 30 September 2026. Feldman naming Microsoft, the October signing and the expected first-quarter 2027 revenue start are taken from his remarks as reported by CNBC; they are his claims, not a Microsoft confirmation. TSN has not seen a Microsoft comment, and no deal size has been disclosed.
