The Livingston, New Jersey-based company rents graphics-processor clusters to AI developers, and its growth has depended on finding power and buildings fast enough to match demand. Denmark is the latest addition. The majority of a planned 22.5 megawatts at atNorth's DEN01 data center in Copenhagen is now online, lifting CoreWeave's European presence to nine data centers across five geographies, the company said in a release. The site feeds surplus heat into the local district heating network, a common feature of Nordic facilities that market cheap renewable power and cool climates to data center tenants.
CoreWeave's backbone has so far linked its North American and European sites over terrestrial and subsea fiber. Starting late in the fourth quarter of 2026, CoreWeave plans to add network access points in Japan, Korea, Australia, Singapore, Indonesia, India and the United Arab Emirates, with the ring of connections completed by mid-2027, the company said. The expansion builds on earlier moves into the Asia-Pacific region, where CoreWeave unveiled its first data centers in Indonesia in August, Reuters reported at the time.
The expansion arrives amid a construction program of unusual scale for a company that listed only in March 2025. Its 51 data centers had more than 1.5 gigawatts of active power between them on June 30, 2026, the release noted; contracted power came to roughly 4.2 gigawatts at the August 11 earnings call. Customers typically sign multi-year take-or-pay contracts, which gives the company visibility but also obliges it to deliver capacity on schedule. Meeting those commitments means securing chips, power and sites well before the capacity is needed. Executives have said international markets should become a major growth driver, and the Denmark site and the Asian network loop are the first concrete pieces of that plan.
