Cerebras European Expansion Bolsters Confidence in OpenAI Deal, UBS Says

Cerebras Systems plans to add 200 megawatts (MW) of data center capacity in Europe by 2027, a significant expansion that analysts at UBS see as a positive development for the company's large-scale partnership with OpenAI.

Expansion Details

In a note to clients, UBS said the announcement provides more clarity on the European and Nordic data centers Cerebras first mentioned during its previous earnings call. The AI company expects to bring its first European capacity online by the end of 2026, with the full 200 MW operational by the end of 2027.

This new European capacity builds on the company's existing infrastructure. Prior to this announcement, UBS estimated Cerebras had approximately 150 MW to 200 MW of contracted capacity across projects in the United States and Canada.

Impact on OpenAI Partnership

The expansion directly addresses investor concerns regarding the deployment of OpenAI's 'Tranche 1' supercomputer, according to UBS. The bank noted that some investors were worried about Cerebras being a relative newcomer to the complex cloud and colocation leasing market.

With this addition, UBS estimates Cerebras now has visibility to approximately 410 MW of announced contracted power capacity. This progress significantly de-risks the build-out, securing a large portion of the estimated 500 MW needed for the first two tranches of the OpenAI deployment.

Broader Context

The move not only increases confidence in the OpenAI project but also provides Cerebras with flexibility for other business opportunities. UBS highlighted that enterprise customers such as Figma and AlphaSense could also benefit as the new sites come online over the next four to six quarters.

The European facilities will join a growing list of infrastructure commitments with partners including Nautilus, Colovore, Digi Power X, WhiteFiber, Scale, and a 300 MW facility with Bell announced in March 2026.
