Prediction: Cerebras' Revenue Will More Than Double in 2027

Cerebras Systems (NASDAQ:CBRS) expects to generate $880 million to $890 million of core revenue in 2026, an outlook management raised in mid-August. Core revenue is the artificial intelligence (AI) computing specialist's preferred non-GAAP (adjusted) measure, and it's the number I'll use throughout. It excludes data center revenue the company merely passes through to customers and adds back a noncash deduction tied to customer warrants.

I think 2027 core revenue tops $1.8 billion -- more than double this year's target. That may sound aggressive for a company that went public in May. I'd argue it's the conservative reading of Cerebras' own numbers.

After all, management's plan for next year is bigger than mine. And Cerebras closed the first half with $25.4 billion of remaining performance obligations, the value of signed customer contracts it hasn't yet turned into revenue.

The prediction doesn't lean on finding new demand. It leans on Cerebras building fast enough to serve what it has already sold.

The ramp is already visible

The second quarter offered the strongest evidence yet. Core revenue rose 103% year over year to about $210 million, accelerating from the first quarter's 92% pace. Core cloud and other services revenue (the business of renting out computing power and related services rather than selling hardware systems) grew 287% year over year to $127.7 million. The losses are shrinking, too, with Cerebras' core operating margin improving to negative 16%, from about negative 42% a year earlier. And management plans for revenue to more than triple in 2027.

Cerebras also raised its full-year target, which had been $855 million to $865 million. Its new range implies about $480 million of core revenue in the second half of the year.

And with the third quarter guided to $214 million to $216 million, that puts the fourth at about $270 million. For perspective, the 2026 target itself represents about 74% growth over 2025.

In other words, a doubling next year arguably wouldn't require a new trajectory -- just the current one holding for another year.

Most of the growth is already under contract

A significant amount of that $25.4 billion backlog, the company's latest quarterly filing says, traces to a single agreement with OpenAI, the ChatGPT maker. But for 2027, the conversion schedule is what matters.

Cerebras expects about 22% of the balance (about $5.6 billion) to be recognized as revenue during the 24 months that end June 30, 2028. The company cautions that the timing can shift at the customer's request. (The backlog converts on Cerebras' reported revenue basis, which ran about 7% below core revenue in the first half.)

Calendar 2027 covers half of that window. And the guided second half of 2026 comes to only about $480 million of core revenue. For next year to fall short of a doubling, then, most of that $5.6 billion would have to crowd into the window's final six months in early 2028.

A shortfall like that is possible. Management, though, is planning for the opposite. A tripling next year would put the steep part of the ramp squarely in 2027.

What could stall the build-out?

The main risk is construction, not demand. Cerebras counts more than 600 megawatts of data center capacity as live or under contract for delivery by the end of 2027.

Manufacturing capacity is set to grow more than tenfold in 2026, and Cerebras says it has secured the wafer supply it needs from Taiwan Semiconductor Manufacturing. Every one of those is a schedule that has to hold.

Notably, three customers accounted for 76% of second-quarter reported revenue, and the backlog itself leans on the OpenAI agreement. If a single buyer's schedule slips, most of a year's growth could slip with it.

The build-out is expensive, too, for a company that remains unprofitable on its core measure. Cerebras is paying for data centers and factory lines ahead of the revenue they'll carry, helped by the $6.4 billion it raised in its May initial public offering (IPO).

A revenue forecast isn't a buy call, of course. With the stock around $203 as of this writing, Cerebras carries a market value near $48 billion, which is more than 25 times the 2027 core revenue I'm predicting -- for a company that hasn't yet turned growth into core profits.

So I'm not a buyer at this level.

Ultimately, though, the revenue call is different. Getting above $1.8 billion next year would take only about two-thirds of what management itself is planning for, on demand the company has already signed. I expect Cerebras to clear that bar.
