Summary
- Polarise and SWI have converted a previously announced majority-equity investment into debt financing.
- The new facility is worth up to an undisclosed high double-digit million-euro amount.
- Polarise plans further AI factories, including an Amberg development starting at 65MW with potential expansion to 120MW.
Polarise has disclosed the scale of the debt financing replacing SWI Stoneweg Icona’s previously proposed majority-equity investment, saying the new facility could reach an undisclosed high double-digit million-euro amount.
The German sovereign-AI infrastructure provider said the financing will support expansion of its European AI cloud platform and the development of further AI factories.
The new disclosure follows DataCentral’s coverage of the restructuring of the SWI transaction, under which the parties moved away from the previously announced majority-equity deal and towards a debt relationship.
Polarise has now confirmed that the replacement is not simply an unspecified financing commitment. The facility is expected to provide up to a substantial double-digit million-euro amount, although the company has not published an exact ceiling, interest rate, maturity, security package, or drawdown conditions.
The shift changes the capital structure behind the expansion. Equity would have given SWI an ownership position and exposed it directly to the value of the Polarise platform. Debt instead gives Polarise capital while leaving the existing ownership structure more intact, but creates repayment and financing obligations that have to be supported by operating cash flow or further capital.
That distinction is particularly relevant in AI infrastructure because development is capital-intensive before utilisation revenue arrives. GPU hardware, electrical capacity, cooling, buildings, networking, and long-lead equipment all require funding ahead of full commercial operation.
Polarise operates AI infrastructure in Oslo and Munich and says further facilities are planned across Europe. Its Amberg project in Bavaria is expected to begin with around 65MW of capacity and has been presented as scalable to 120MW.
The company is using what it calls an AI Pod model intended to integrate modular AI infrastructure into existing buildings as well as purpose-built facilities. The proposition is that reused or adapted buildings can shorten parts of the development programme compared with a complete greenfield build.
That approach still depends heavily on the electrical and thermal characteristics of the host site. A building suitable in floor area may not have the grid capacity, transformers, cooling plant, structural loading, network connectivity, or heat rejection needed for high-density GPU infrastructure.
Financing therefore remains tied to delivery evidence. Debt providers need confidence that contracted customers, hardware deployment, power access, and commissioning programmes can generate sufficient revenue on the schedule assumed in the financing model.
Polarise says it will continue to evaluate additional strategic and financial partnerships. The SWI facility should consequently be viewed as one element of a wider capital plan rather than the complete funding requirement for a European AI data centre portfolio.
The value disclosure nevertheless adds substance to the transaction change reported a day earlier. Moving from majority ownership to debt could have been a retreat from the original deal; the high double-digit million-euro facility shows that SWI is still committing material capital to the platform, albeit through a different risk structure.
The next test is how much physical capacity that capital can move into operation. For AI infrastructure developers, financing announcements increasingly need to be read alongside secured power, deployed GPUs, cooling capability, and customer commitments. Debt is useful only when those assets can be turned into working megawatts.
