Bitcoin Miner IREN Expands into Europe with Nostrum Purchase Amid AI Shift

Bitcoin miner IREN’s bold push into Europe began in June 2026, when the company closed its acquisition of Spain-based Nostrum Group. This deal didn’t just immediately add 490 megawatts (MW) of energy capacity to IREN’s portfolio—it accelerated IREN’s shift from classic cryptocurrency mining to advanced artificial intelligence (AI) infrastructure, according to Financefeeds’ coverage. Since this transaction hit headlines, IREN’s shares on NASDAQ jumped almost 4%, trading between $60.41 and $63.17 as more than 21 million shares changed hands. Those numbers reflect a much bigger trend: major Bitcoin miners are now chasing global demand for AI computing power, eyeing regions beyond just Europe—including Australia.

Spain is among its most compelling entry points, with abundant renewables and strong fiber connectivity.

IREN expands its European footprint with Nostrum deal

Financefeeds reports the Nostrum acquisition doesn’t just grant IREN a foothold in Spain—it gives the company a launching pad in one of Europe’s most dynamic AI infrastructure hubs. That immediate 490MW of added capacity strengthens IREN’s position as it pivots away from legacy Bitcoin mining toward cloud computing services aimed squarely at surging AI workloads. So, the acquisition fits seamlessly into IREN’s larger strategy for next-generation digital infrastructure.

The strategic rationale behind acquiring Nostrum

IREN’s real motivation: acquiring infrastructure that can handle high-density, cutting-edge AI workloads and tapping largely renewable sources. Co-founder Daniel Roberts highlights Europe as not just big—it’s one of the fastest-growing AI infrastructure markets. The 490MW of capacity, delivered via Spain’s modern, flexible grid, positions IREN to scale rapidly in the region. By snapping up Nostrum, IREN gained immediate access to permitted projects and a scalable expansion platform.

Financial impact and market reaction

After the Nostrum agreement, IREN’s shares surged almost 4% to about $62. That volume spike—over 21 million shares traded—signals growing institutional interest. IREN’s stock oscillated between $60.41 and $63.17, highlighting real-time volatility as traders assessed the impact of the AI-focused strategy. Year-to-date, IREN’s price has jumped between 60% and 65%, and its one-year returns now exceed 500%.

This 500% surge reflects the market’s confidence in IREN’s pivot to next-generation infrastructure. IREN is now considered a bellwether for legacy miners striving to adapt as broader macro trends reward companies holding broad, diversified computing power—not just Bitcoin hash rate, according to Crypto Economy.

Shift from mining to AI-driven infrastructure

Crypto Economy points out that IREN’s turn toward AI infrastructure hasn’t been haphazard. Instead, it’s calculated and far-reaching—mirrored in synchronized moves across both Spain and Australia.

The acquisition of Nostrum’s 50-person engineering team signals renewed focus on technical mastery and the specialized expertise needed to build and maintain robust, future-ready AI facilities. As institutional demand for large language model (LLM) compute and generative AI training explodes in 2026, IREN’s infrastructure is positioned to serve clients demanding scale, efficiency, and reliability.

Why AI infrastructure demand is surging in Spain and Europe

Financefeeds’ analysis reveals Spain’s data center market has quickly become a magnet for global investors. The country offers abundant renewables, a predictable regulatory environment, and proximity to key user clusters in both Europe and North Africa. With IREN entering through the Nostrum deal, the company gets early access to crucial power contracts and approved land—advantages that clear obstacles still tripping up many competitors.

This early-mover advantage aligns with the regional push by “hyperscalers”—massive tech firms delivering enormous volumes of cloud, storage, and compute. They’re now flocking to Southern Europe for its cost efficiency and reliable energy. Within this favorable macro backdrop, IREN’s able to pitch sustainable power pricing and renewable sourcing to major tech clients, meeting corporate climate goals and leveraging local policy support.

There is growing discussion that IREN’s Iberian assets could soon be tied into pan-European compute clusters—a move that could facilitate cross-border sharing of cloud resources and enable rapid, distributed AI training throughout the continent.

IREN’s dual-continent growth: Australia and Europe

The Nostrum deal instantly delivered 490MW of European capacity, while the 800MW Australian campus announced in May 2026 promises major scale for Asia-Pacific.

The upcoming South Australian campus—purpose-built for AI and cloud—cements IREN’s evolving identity.

What’s next in IREN’s AI journey

Crypto Economy confirms IREN now holds some of the world’s largest new-build data center capacity among ex-mining operators. That total includes the 490MW of ready-to-launch Spanish resource and another 800MW coming soon in South Australia. And, onboarding more than 50 Nostrum engineering specialists arms IREN with a technical team equipped to handle multi-client, complex deployments across AI, cloud, and digital asset customers.
