Cerebras Systems announced plans to expand its European data center capacity to 200MW by the end of 2027, increasing its total contracted power capacity to about 410MW. This expansion supports OpenAI's first tranche deployment and reduces execution risks for Cerebras in the cloud and colocation market. UBS analysts view this as a positive development, enhancing confidence in OpenAI's infrastructure ramp and providing Cerebras flexibility for future business opportunities. The second OpenAI tranche is expected to ramp up in the second half of 2027, with potential for more agreements with large colocation providers if deployment continues through Cerebras' cloud platform.
