IREN completed its acquisition of Nostrum Group on June 15, 2026, adding approximately 490MW of secured power in Spain as the Nasdaq-listed bitcoin miner accelerates its pivot toward AI data center infrastructure across Europe.
The company said it acquired Ingenostrum, S.L., a developer of grid-connected AI data centers in Spain, in a deal that also brings a further development pipeline and a team of more than 50 people across development, engineering, construction and operations. Financial terms of the transaction were not disclosed.
IREN’s European expansion backs a broader AI infrastructure play
When IREN first announced the Nostrum deal on May 7, 2026, it said the acquisition would lift its total power portfolio to 5GW. That figure spans operations in North America and now Europe, positioning the company as one of the larger power holders among firms that straddle crypto mining and AI cloud services.
The Spanish assets are attractive in part because of the country’s supportive AI policy settings, constructive permitting environment and abundant low-cost renewable energy. IREN framed the Nostrum team’s local expertise in development, engineering and construction as critical to executing on its European buildout plans.
The acquisition follows a separate milestone disclosed on the same May 7 announcement: a five-year AI infrastructure cloud services contract with NVIDIA valued at approximately $3.4 billion, to be serviced by about 60MW at IREN’s facility in Childress, Texas. That contract underscores why the company is racing to secure power capacity well beyond its existing North American footprint, a pattern similar to how Strategy has been deploying capital to scale its bitcoin holdings.
Mining roots, AI ambitions
IREN still mines bitcoin, but the Nostrum deal signals that AI cloud infrastructure is now the primary growth vector. Data Center Dynamics reported that the company is actively pivoting away from cryptomining toward its AI cloud business, even as it maintains mining operations.
Bitcoin traded at $66,616 at press time, up roughly 4.4% over 24 hours. The crypto Fear and Greed Index sat at 20, reflecting extreme fear across the market.
A rising bitcoin price gives miners like IREN healthy cash flows to fund diversification, rather than forcing a retreat from crypto altogether. The dual-track approach, maintaining mining revenue while building out AI capacity, reflects a playbook several publicly listed miners have adopted as demand for GPU compute surges.
What the deal means for crypto and AI infrastructure watchers
The convergence of bitcoin mining and AI data centers rests on a shared bottleneck: access to large-scale, low-cost power. Miners that secured grid connections and power purchase agreements during the crypto bull cycles now hold assets that hyperscalers and AI cloud providers need. IREN’s Nostrum acquisition is a direct example of that conversion.
For market participants tracking how exchanges are expanding derivative offerings and how futures platforms are adding new protections, the IREN deal adds a different dimension: the infrastructure layer beneath trading activity is itself becoming an investable thesis tied to AI demand.
With 490MW of secured European power, a 5GW global portfolio and a $3.4 billion NVIDIA contract in hand, IREN has staked one of the more aggressive positions among former pure-play miners. Whether the AI cloud revenue materializes at the scale implied by those commitments will determine if the pivot pays off.
