CoreWeave Adds Stockholm AI Capacity With Power Terms Still Undisclosed
CoreWeave signed a co-location agreement with Conapto for two Stockholm campuses, adding European AI cloud capacity powered by renewable energy while leaving capacity size and customer commitments undisclosed.
Stockholm Campuses Add AI Cloud Capacity
CoreWeave has signed a co-location agreement with Conapto for additional AI cloud capacity across two campuses in Stockholm.
The companies said initial capacity is already online at Stockholm 4 South and that both campuses will use renewable energy sources.
The Sweden deployment provides another European site option for customers that need high-performance compute, networking, storage and software orchestration for AI workloads.
CoreWeave said the capacity uses NVIDIA Blackwell Architecture, NVIDIA Vera Rubin Platforms and NVIDIA Quantum-X800 InfiniBand.
The hardware detail defines the site as production AI infrastructure, not ordinary colocation space.
Customers still need to know how much capacity is available, how quickly racks can be reserved and whether the Stockholm campuses can support sustained training or inference work.
The deal fits a wider European AI infrastructure buildout, but the companies did not disclose the megawatt capacity assigned to the Conapto campuses, the number of systems installed, the contract value or named customers using the new capacity.
The missing operating detail limits how buyers can assess the immediate compute added by the Stockholm expansion.
Renewable Power Comes With Heat Recovery
CoreWeave and Conapto framed the partnership around AI capacity and sustainability.
Conapto CEO Håkan Björklund said the site pairs high-density infrastructure with fully renewable electricity and heat reuse through Stockholm's district heating network.
Those power terms make the Sweden deployment more specific than a generic cloud expansion.
AI infrastructure buyers increasingly need to know whether a site can secure electricity, cooling and grid acceptance before large training or inference workloads move in.
In this case, the disclosed evidence is renewable-energy sourcing, heat recovery and an active Stockholm 4 South deployment.
The release also places the Swedish capacity inside CoreWeave's public-company expansion discipline.
CoreWeave listed the deal as part of its international footprint rather than a standalone data center lease.
Enterprises still need to confirm whether the added Stockholm capacity can be reserved, governed and operated under their own data, latency and sustainability requirements.
CoreWeave COO Sachin Jain said Sweden has been central to the company's European strategy since its first continental investment.
He linked Conapto's local expertise and sustainable energy profile to urgent high-performance AI compute with reliability and environmental credentials for enterprise deployments.
Europe Footprint Reaches Eight Sites
CoreWeave said the Conapto agreement brings its European sites to eight.
The company's March 31, 2026 footprint included 49 data centres globally.
CoreWeave also reported active power above 1GW and contracted power above 3.5GW for AI workloads at scale.
The company also said nine of the 10 leading foundation model providers use CoreWeave.
That customer claim supports the scale of demand, although the Stockholm announcement did not identify which AI labs, enterprises or developers will use the Conapto capacity.
CoreWeave and Conapto planned to discuss Sweden's role in AI infrastructure and Europe's AI capacity requirements at Tech Arena at Almedalen on June 25.
The commercial proof after the event will be whether CoreWeave names customers, discloses capacity at the two campuses or ties the Stockholm sites to specific production workloads.
