SWI Stoneweg Icona Group acquires a majority stake in Polarise, committing €1B to expand AI compute and GPU services across Europe.
SWI Stoneweg Icona Group has agreed to acquire a majority stake in Polarise, a leading European NVIDIA Cloud Preferred Partner, in a move that deepens its bet on artificial intelligence infrastructure.
The transaction, which includes a €100 million equity investment for operations, values Polarise at approximately €500 million upon completion. SWI has also committed an additional €1 billion to expand the partnership’s digital infrastructure footprint, signaling a broader push into GPU- and AI-as-a-Service capabilities across Europe.
The deal integrates Polarise’s AI compute operations into SWI’s AiOnX platform, a 2.3-gigawatt Europe-wide data center portfolio. By adding GPU-as-a-Service and AI-as-a-Service to its existing assets, SWI is positioning itself not only as a data center developer but as an operator of AI-native infrastructure.
Based in Germany, Polarise provides high-performance computing capacity and AI infrastructure services to enterprise and sovereign clients. The company is both an NVIDIA Preferred Partner and an official NVIDIA Cloud Service Provider. It recently launched an industrial-scale AI factory in Germany in partnership with Deutsche Telekom and NVIDIA, following an earlier facility in Oslo, Norway.
The partnership gives Polarise access to SWI’s capital base and power infrastructure, enabling accelerated expansion across key European markets. The €1 billion capital commitment is intended to fund site pipeline development and the construction of additional AI factories powered by NVIDIA’s latest GPUs.
Max-Hervé George, founder and chief executive of SWI Group, described the transaction as an extension of the firm’s strategy to build a fully integrated digital infrastructure platform. “Our ambition targets the creation of the foremost digital infrastructure developer and operator in Europe,” he said, citing Polarise’s expertise in GPU compute and client-facing AI services.

Michel Boutouil, founder and chief executive of Polarise, said the partnership would accelerate the company’s expansion at a time when Europe is seeking to strengthen its position in the global AI race. The backing, he said, provides both financial certainty and access to strategically located power capacity — a critical constraint in scaling AI infrastructure.
The transaction underscores a broader shift in Europe’s digital economy, where control over power, compute and capital is increasingly seen as essential to competing in AI. Rather than treating AI infrastructure as a niche extension of data centers, SWI and Polarise are betting it will become a foundational layer of the continent’s industrial strategy.
