IREN closed its acquisition of Spain-based AI data center developer Nostrum Group on Monday, adding roughly 490 megawatts of secured, grid-connected power to a portfolio that is rapidly being repositioned around AI and high-performance compute. The deal brings more than 50 staff across development, engineering, construction and operations into IREN's fold and gives the company its first beachhead in Europe, a market co-CEO Daniel Roberts called "one of the largest and fastest-growing" for AI infrastructure.
Why it matters
Nostrum is IREN's second major data center move in two months. In late May, IREN unveiled an 800-megawatt campus in South Australia aimed at Asia-Pacific AI demand, and the European deal extends the same template — secured grid power plus shovel-ready sites — into a continent with tightening AI-cloud capacity and a long queue of hyperscaler tenants. Spain's grid, weighted toward renewables and paired with strong fiber connectivity, gives IREN a power-cost profile it could not replicate in the company's legacy mining markets.
The acquisition also keeps IREN in step with a sectoral rotation that has rewarded miners who can credibly pivot: the company now counts Microsoft, via a roughly $3.65 billion AI cloud agreement, and Nvidia, via warrants tied to 30 million shares, among the names underwriting the pivot. Each new megawatt added is a kilowatt that can be reallocated from BTC mining to GPU compute as contract economics dictate.
Market impact
IREN shares traded near $62 on Monday, up roughly 4% on the announcement — a measured reaction that suggests investors were already partially pricing the European expansion flagged in prior quarters. The sharper read is the cumulative footprint: with 490MW in Spain and 800MW in Australia added inside a single month, IREN has materially accelerated the build-out needed to convert its AI cloud pipeline into revenue rather than capacity on a slide. Watch for the next milestone: contracted tenant mix at the Spain site and any disclosure of grid-interconnect timelines, since power-availability claims are only as strong as the energization dates attached to them.
Frequently asked questions
-
What did IREN actually acquire in the Nostrum deal?
IREN completed its acquisition of Ingenostrum, S.L. (Nostrum Group), a Spain-based developer of AI data centers. The deal adds roughly 490 megawatts of secured, grid-connected power and more than 50 staff across development, engineering, construction and operations.
-
How does the Nostrum acquisition fit into IREN's broader AI build-out?
It is IREN's second major data center move in roughly two months, following the late-May announcement of an 800-megawatt campus in South Australia targeting Asia-Pacific AI demand. Together, the deals extend a build-out template of secured grid power plus shovel-ready sites onto two new continents.
-
Why Spain, and why now, for IREN's European entry?
Co-CEO Daniel Roberts framed Europe as one of the largest and fastest-growing AI infrastructure markets, with Spain singled out for abundant renewables and strong fiber connectivity — a power-cost profile IREN could not easily replicate in its legacy mining markets.
-
What does the Microsoft and Nvidia involvement mean for the pivot?
Microsoft is anchored by a roughly $3.65 billion AI cloud agreement, while Nvidia backs the expansion via warrants tied to 30 million IREN shares. Each new megawatt added can be reallocated between BTC mining and GPU compute as contract economics dictate.
-
How did IREN shares react to the announcement?
IREN traded near $62 on Monday, up roughly 4% on the day — a measured move that suggests investors were already partially pricing the European expansion flagged in prior quarters.
