Bitcoin miner IREN has acquired the Nostrum Group, adding 490 megawatts of capacity in Spain. The deal marks the company's entry into Europe's growing AI cloud market and signals a strategic shift away from its Bitcoin mining roots.
The Nostrum Deal
IREN announced the acquisition of Nostrum Group this week. The deal brings 490 MW of capacity in Spain, a significant addition to IREN's power portfolio. The company did not disclose financial terms. The capacity is expected to be used for AI cloud services, which require substantial energy for data centers.
Why Spain
Spain offers abundant renewable energy, attractive for power-hungry AI workloads. The country has been positioning itself as a European hub for data centers. For IREN, the acquisition provides a foothold in a market where demand for AI compute is rising fast. The company now has a direct path to serve European clients without relying on third-party infrastructure.
A Strategic Pivot
IREN is shifting its strategic focus from Bitcoin mining to AI cloud services. The move mirrors a broader trend among miners who are repurposing their energy assets for AI. Bitcoin mining margins have tightened, and AI cloud offers higher revenue potential. IREN's pivot is one of the most concrete examples yet: a pure-play miner buying capacity specifically for AI, not for hashing.
IREN will now integrate the Nostrum assets and begin deploying AI cloud infrastructure. The company faces the challenge of converting that 490 MW into paying AI customers. It's a different business from mining — more about service reliability and customer relationships than about hash rate. For IREN, the real work begins now: turning Spanish megawatts into AI revenue.
