STOCKHOLM, Sweden, June 26, 2026 – CoreWeave is adding renewable energy-backed AI infrastructure capacity in Stockholm through a colocation agreement with Conapto covering two data center campuses, with initial capacity already online at Stockholm 4 South.
Both campuses will use renewable energy sources and provide access to CoreWeave’s AI cloud infrastructure. The sites will serve AI labs, enterprises, and developers running compute-intensive workloads across Europe.
The Stockholm deployment uses NVIDIA Blackwell Architecture and NVIDIA Vera Rubin Platforms connected with NVIDIA Quantum-X800 InfiniBand. CoreWeave said the capacity supports customers moving AI workloads from experimentation into production.
The agreement brings CoreWeave’s European sites to eight. As of March 31, 2026, CoreWeave operated 49 data centers globally, with more than 1 GW of active power and over 3.5 GW of contracted power supporting AI workloads.
“Sweden has been central to CoreWeave’s European strategy since our first continental investment,” said Sachin Jain, chief operating officer, CoreWeave. “Conapto’s local expertise and sustainable energy profile allows us to provide our customers what they need: urgent high performance AI compute with the reliability and environmental credentials that enterprise AI deployments demand.”
“We’re excited to partner with CoreWeave to support the rapidly growing demand for their AI cloud platform,” says Håkan Björklund, CEO, Conapto. “CoreWeave is at the forefront of AI innovation, and we’re proud to provide the resilient, high-density infrastructure needed to power their next phase of growth. Combined with our commitment to 100 percent renewable energy and heat recovery to Stockholm’s district heating network, this partnership demonstrates how advanced AI infrastructure and sustainability can go hand in hand.”
CoreWeave said nine of the 10 foundation model providers use its infrastructure. The company also cited MLPerf results in inference and training, Platinum rankings in SemiAnalysis ClusterMAX 1.0 and 2.0, and artificial analysis rankings for inference speed and price-performance for Moonshot AI’s Kimi K2.6 and Kimi K2.7 Code.
