SWI raises €800 million in equity for US and Europe data center buildout

SWI Group has raised €800 million ($892.4m) from institutional investors through a new share issuance, Data Center Dynamics first reported. The Euronext Amsterdam-listed real estate investor will direct the proceeds toward data center and AI compute expansion in Europe and the United States.

SWI said the new funds provide "substantial" capital for its digital infrastructure and AI compute platforms, including power infrastructure, compute deployments and the execution of its development pipeline, according to the report.

Total equity raised since March 2026 now exceeds €1 billion ($1.1bn).

SWI was formed from the merger of Stoneweg and Icona Capital last year and reports about €11 billion ($12.27bn) in assets under management. It announced last year that it was launching its own data center fund and platform, taking a stake in AiOnX, which has projects in the UK, Ireland and mainland Europe.

The firm has also acquired a majority stake in the cryptominer Genesis Digital Assets, which operates 15 crypto data centers in the US and Sweden totaling 1.3GW.

The acquired company is to be renamed SWI Digital and form the basis of SWI's US data center platform, while the Stoneweg Europe Stapled Trust is looking at potentially redeveloping around ten industrial sites across four European countries for data center use.

The raise is equity at the listed-company level rather than project-level debt attached to individual sites. SWI lists power infrastructure explicitly among the uses of proceeds.

The company also says it aims to develop its own HPC and GPU-as-a-service platform.
