SWI amplía capital en 800 millones para crecer en infraestructura de IA

SWI Group, a holding company formed from the integration of Spanish Stoneweg and alternative investment firm Icona Capital, has announced it has raised €800 million in new capital. The additional funding will be used to expand its digital infrastructure platform and AI computing capabilities across Europe and the United States. The company, which went public on Euronext Amsterdam in February, now has a total capitalization of €6.1 billion, with 558.399.385 ordinary shares in circulation.

This latest round of funding brings total capital raised in the period to over €1 billion, up from the €260 million raised in March. SWI Group says the new capital will strengthen its financial position and enable it to pursue its large-scale growth strategy, including further investments in AI and the expansion of its stake in existing investments.

The company aims to maintain its pace with the markets for computing and data centers, according to Max-Hervé George, SWI Group's founder and CEO. Founded in 2025 through the integration of Stoneweg, launched in 2015 by Jaume Sabater and Joaquín Castellví, and Icona Capital, SWI Group currently invests about 80% of its capital in digital infrastructure and also manages real estate assets.

The company operates through several specialized divisions, such as SWI Compute, focused on renting AI processing chips and energy, and AiOnX, a data center development platform for hyperscalers. SWI Group now has a total of approximately four GW of energy capacity across Europe, including Spain and the United States. In August, the company announced its joining of Nvidia's Cloud Partner program as a preferred partner, giving it greater ability to purchase, install, and operate Nvidia's graphics processing units (GPUs) and AI computing chips. SWI Group also holds a 32% stake in a Singapore-listed REIT, Stoneweg European Trust.
