Cerebras (CBRS) Plants A 165 MW Flag In Finland While Still Losing Money

On September 1, Cerebras Systems (NASDAQ:CBRS) announced a new AI data center in Mikkeli, Finland, built with partner Compute Nordic Finland. The site will grow in stages to 165 MW of contracted capacity, and construction on the first 50 MW is already under way. It is a big physical commitment from a company that sells itself on speed. But the results it posted on August 12, 2026 show demand racing well ahead of profits.

A Backlog Hungry For Capacity

Mikkeli reads less like a hopeful land grab and more like a staged build with contracts behind it. The deal runs through a series of service orders, each with a seven-year term, and capacity steps up from 50 MW to 80 MW and eventually 165 MW as the site is delivered. An independent study dated September 12, 2025 put the eventual regional investment at €1.0 billion to €1.7 billion, a large sum for one regional project. Cerebras also says the campus is designed for closed-loop water cooling and for sending waste heat back to the community.

The reason to build is sitting in the order book. On August 12, Cerebras reported that cloud revenue for the quarter ended June 30 rose 281% from a year earlier, with $25.4 billion in customer obligations still to be delivered. That pile dwarfs a single quarter’s sales, so the race is to add enough capacity to serve it. Cerebras also skips several parts that are scarce across the industry, including HBM memory and CoWoS packaging, and it has secured the wafer supply it needs to keep growing. Core gross margin reached 41%, roughly 940 basis points above a year earlier, a sign the economics improve as volume grows. The company also raised its full-year outlook on every core metric.

Speedy Growth, Stubborn Losses

The catch is that this growth is being bought with heavy losses. On a GAAP basis, second-quarter gross margin was 14% and operating margin was negative 265%. Cerebras highlights a core measure that strips out stock compensation, warrant amortization, and pass-through data center costs, and even that shows an operating margin of negative 16%. Core revenue of $209.9 million also sits above the GAAP figure of $180.1 million, so it pays to know which version you are reading.

The outlook adds a wrinkle. For the third quarter, Cerebras guided to core margins lower than what it delivered in the second, with operating margin landing between negative 25% and negative 23%. Core revenue guidance of $214 million to $216 million is only a modest step up. Mikkeli adds to the pressure, because Compute Nordic Finland handles development, operations and the customer interface, which means Cerebras is buying capacity from a partner on long terms. That commitment only works if the customers keep coming.

Big Money Arrives, Shorts Circle

Hedge fund ownership went from zero funds in the prior quarter to 78 in the most recent one. That means big money went from absent to present. Short interest sits at 11.88% of the float, a heavy level of skepticism that can also fuel a sharp squeeze if good news keeps coming.

Speed Versus The Spreadsheet

Mikkeli captures the whole debate in a single site. On one side sits efficient, staged capacity backed by a backlog that needs it. On the other sits a long commitment from a company that has not yet turned fast growth into profit. The bull case needs margins to keep climbing as new capacity comes online and orders turn into billed revenue, while the bear case gets its proof if the guided dip turns out to be the start of a pattern. Over a multiyear stretch, the question is whether speed can eventually pay for the buildout.
