Nasdaq-listed bitcoin miner IREN Limited completed its acquisition of Spain's Nostrum Group on Monday, marking the company's first move into Europe. The deal adds 490 megawatts of secured, grid-connected power capacity to IREN's portfolio and gives the firm a base for building out AI cloud infrastructure.
What IREN gets
The acquisition includes Nostrum Group's entire team of 50 people, plus a Spanish platform that IREN says is built for artificial intelligence data center development. IREN has been pushing beyond pure bitcoin mining into AI cloud services this year. This deal locks in a sizable chunk of grid-connected power in a region where energy prices and renewable availability are drawing data center operators.
Why Spain
Spain has become a hotspot for energy-intensive computing. The country's grid offers relatively cheap renewables, and its government has courted data center investment. IREN's 490 MW of secured capacity there isn't tiny — it's roughly equivalent to what some dedicated AI data center projects consume. The company now has a physical foothold in continental Europe, not just a mining operation.
IREN isn't the first bitcoin miner to chase AI workloads. The playbook is simple: miners already own the power infrastructure and the facilities. Routing some of that power to AI training and inference jobs can bring in more predictable revenue than mining alone, where bitcoin price swings are brutal. The timing isn't bad — energy contracts locked in months ago may look cheap compared to what new builds would cost today.
Adding 50 experienced hires from Nostrum won't hurt either. That's a ready-made operations and engineering team that knows Spanish energy markets and permitting. IREN can move faster than building from scratch.
