Microsoft Signs Capacity Deal at Pure DC's 550MW Finland Campus, $8.55B Buildout Planned

Microsoft has signed a capacity deal at Pure DC's planned 550MW data center campus in Seinäjoki, Finland, with a total projected investment of €7.5 billion ($8.55 billion). Phase 1 delivers 110MW of AI-focused capacity, fully leased to Microsoft, using direct-to-chip liquid cooling and waste heat recovery. The project is one of Finland's largest inward investments and will create about 3,000 construction jobs over a decade.

The project, designated SJK01, carries a total projected investment of €7.5 billion $8.55 billion , making it one of Finland's largest-ever inward investment projects and the largest by a UK company in the country 1 . Phase 1 will deliver 110MW of AI-focused capacity at a cost of over €1.5 billion $1.7 billion . The substation for the first data hall has already been constructed and is operational, and all planning permissions and power requirements for the initial phase have been secured. Phase 1 is already fully leased 1 https://www.datacenterdynamics.com/en/news/microsoft-signs-on-for-capacity-at-pure-dc-data-center-in-finland-report/ 2 . The deal deepens an existing relationship between Pure DC and Microsoft. The developer's 78MW Amsterdam campus — a three-tower, €1 billion-plus facility — is already fully leased to Microsoft 4 . Pure DC also operates data center campuses in Dublin and Abu Dhabi . 4 https://tech.eu/2026/05/27/london-data-centre-firm-pure-dc-secures-27bn-for-european-and-middle-east-expansion/ The Site Pure DC purchased a 22.3-hectare 55-acre plot of land in the Kivenneva data center area of Seinäjoki on April 15, 2026, for €3.86 million $4.55 million . Three data center buildings are planned for the site, which sits in the South Ostrobothnia region of western central Finland 2 . The full campus is designed to scale to 550MW+ across 370 acres, using repeatable 40MW AI-ready modules. Direct-to-chip liquid cooling is specified for high-density AI workloads. Waste heat from the facility will be repurposed into the local district heating network 1 https://www.datacenterdynamics.com/en/news/microsoft-signs-on-for-capacity-at-pure-dc-data-center-in-finland-report/ 2 . Construction across all phases is expected to span approximately a decade, generating around 3,000 construction jobs in the region 1 . Pure DC's Financing and Expansion Pure DC secured $2.7 billion in financing in May 2026, adding SMBC, Allianz Global Investors, and ABN AMRO as new lenders. A substantial portion of the facility was secured against the company's Dublin and Amsterdam campuses 4 . CEO Gary Wojtaszek said the company had 'materially strengthened and diversified our financing platform' over the preceding year 4 . The company claims over 1GW of capacity either live or under development globally . 1 https://www.datacenterdynamics.com/en/news/microsoft-signs-on-for-capacity-at-pure-dc-data-center-in-finland-report/ Oaktree Capital, Pure DC's backer, has separately been reported as seeking a minority investor for the platform, reflecting the capital-intensive nature of the hyperscale development pipeline 5 . Microsoft's Nordic Expansion The Finland deal sits within a broader Microsoft push into the Nordics. In June 2026, Microsoft signed a preliminary agreement to acquire approximately 190 hectares of land in Vaasa and Mustasaari, also on Finland's west coast, for a separate data center development 3 . Microsoft's appetite for Nordic capacity reflects the region's advantages for large-scale AI infrastructure: competitive energy costs, cold climate suitable for cooling, robust grid infrastructure, and proximity to subsea cable routes. Finland's grid is also relatively clean, drawing heavily on nuclear and renewables 3 . British Ambassador to Finland Laura Davies described the Pure DC project as the 'largest yet by a UK company in Finland,' underscoring the diplomatic significance of cross-border data center investment in Europe's AI buildout 1 . Market Context Microsoft shares traded at $385.60 on July 14, down 1.4% on the day, with a market capitalization of approximately $2.86 trillion. The stock has traded between $349.20 and $555.45 over the past 52 weeks 6 . The deal adds to a wave of hyperscaler capacity commitments across Europe, where operators are racing to secure sites, power, and permits ahead of AI inference and training demand. Pure DC's model — purchasing land, building to suit, and leasing to hyperscalers — positions it as one of several European developers competing for Microsoft, Google, and Amazon contracts alongside established players like Equinix and Digital Realty 4 .
