Bitcoin mining company IREN has acquired Nostrum Group, a Spain-based AI data center developer, to expand its AI cloud platform in Europe.
The move signals a strategic shift for the company as it diversifies away from pure cryptocurrency mining. By securing large-scale power infrastructure, IREN aims to capture the growing demand for artificial intelligence computing and cloud services across the European market.
Through the acquisition of Nostrum Group, IREN has added 490 MW of secured power capacity [1]. This expansion supports the company's broader goal of leveraging high-density power for AI data centers. The company has previously outlined plans to reach an AI infrastructure capacity of 480 MW by 2026 [3].
This transition into AI infrastructure follows a significant partnership with Nvidia. IREN entered into a five-year deal valued at $3.4 billion [2]. Following the announcement of the Nvidia agreement, IREN stock increased by over seven percent [2].
The pivot comes as the company navigates fluctuations in the cryptocurrency market. Recent reports indicate that IREN's third-quarter revenue missed targets due to weaker Bitcoin prices, prompting the firm to focus more heavily on its expansion plans [3]. By integrating Nostrum Group's assets, IREN establishes a physical and operational foothold in Spain, providing the necessary energy resources to host the hardware required for advanced AI workloads.
Data centers for AI require significantly more power and cooling than traditional cloud computing. The secured power obtained from the Nostrum deal allows IREN to scale its operations without the typical delays associated with securing new energy permits in Europe.

IREN's acquisition of Nostrum Group reflects a broader trend where Bitcoin miners are repurposing their expertise in power procurement and heat management to enter the AI infrastructure market. Because AI training and inference require massive amounts of electricity, the primary barrier to entry is often power availability rather than hardware. By securing nearly 500 MW in Spain, IREN is transforming from a niche crypto-asset producer into a diversified energy and compute provider.
