IREN Buys Spain’s Nostrum Group, Expands AI Cloud Push in Europe

IREN is pushing deeper into AI cloud infrastructure with a new Spain-based acquisition that gives the Bitcoin miner its first European foothold and a much larger runway for non-Bitcoin revenue.

• IREN acquires Nostrum Group to expand into Europe
• 490MW of secured, grid-connected power added in Spain
• AI cloud revenue is rising while Bitcoin mining revenue falls
• Public miners are chasing higher-margin AI contracts and long-term compute demand

IREN Limited has completed its acquisition of Ingenostrum, S.L. (Nostrum Group), a Spanish infrastructure company that brings roughly 490MW of secured, grid-connected power, a development pipeline, and more than 50 employees into the fold. Nostrum’s operations will continue under the IREN brand, and Spain becomes the company’s first European market.

That matters because this is not just a geographic expansion. It is a sign that one of the public Bitcoin miners most aggressively leaning into AI cloud infrastructure is now treating Europe as a serious growth market. For newer readers: the same kind of power-hungry sites once built for Bitcoin mining can often be repurposed for AI workloads if they have the right ingredients — cheap or reliable electricity, enough land, cooling capacity, and strong fiber connectivity. In plain English: no power, no GPUs, no party.

IREN says Europe is a major and fast-growing market for AI infrastructure, and co-CEO Daniel Roberts made the strategy bluntly clear:

“Europe is one of the largest and fastest-growing markets for AI infrastructure, and Spain is among its most compelling entry points.”

Roberts also highlighted the bottleneck that is shaping the entire sector:

“The world is structurally short compute, and the bottleneck is delivered data center and GPU capacity.”

That phrase, “structurally short compute,” means there simply is not enough usable computing capacity — especially GPU-backed data center space — to satisfy demand. The world may have plenty of hype, but hype does not train models, run inference, or keep enterprise AI contracts online when the lights go out. Infrastructure does that.

Why Spain, and why now?

IREN pointed to two obvious advantages behind the move: renewable power and fiber connectivity. That combination matters because AI infrastructure is not just about owning chips. It is about delivering those chips with enough electricity, cooling, and connectivity to actually make them useful at scale.

Spain gives IREN a foothold in a market where energy access and data-center buildout potential can line up with rising AI demand. Gabriel Nebreda, CEO of Nostrum Group, said the company had already laid the groundwork:

“We have spent years assembling one of Spain’s most advanced AI infrastructure pipelines.”

He added that joining IREN would help develop that pipeline “at the speed and scale Europe’s AI infrastructure demand requires.” That’s the kind of statement that usually means a company has done the hard yards already and now wants a partner with more capital, more reach, and a stronger balance sheet to turn plans into revenue.

In practical terms, 490MW is serious capacity. It is not a side project or a vanity site. It is enough to matter in a sector where the real constraint is no longer just access to chips, but access to power and the physical ability to host those chips in the first place.

The money trail tells the story

IREN’s latest quarterly figures show exactly why this pivot is happening. Bitcoin mining revenue came in at $111.2 million, down from $167.4 million. At the same time, AI cloud services revenue rose to $33.6 million from $17.3 million.

The company still reported a hefty net loss of $247.8 million, including non-cash impairments mainly tied to decommissioned mining hardware. Non-cash impairments are paper losses: they reduce reported earnings because assets have lost value on the books, but they do not represent an immediate cash outflow. In other words, it is accounting pain, but not necessarily a fresh cash burn in the quarter.

IREN said lower average Bitcoin prices and the removal of mining hardware ahead of GPU installation hurt mining revenue. That is the trade-off here. Moving from ASIC-heavy Bitcoin mining to AI compute is not as simple as swapping a logo on the server room door. ASICs are purpose-built for mining Bitcoin; GPUs are the workhorses of AI. Converting facilities takes time, money, logistics, and more patience than most token-pumping narratives can tolerate.

So yes, the AI side is growing, but nobody should mistake that for a frictionless transformation. The business is being rebuilt in real time, and that comes with ugly numbers before the prettier ones show up.

IREN is not alone

The company’s push into Spain fits a much broader trend across the public mining sector. Miners are increasingly being valued not only for how much Bitcoin they can produce, but for how effectively they can deliver AI compute under long-term contracts.

IREN has already signed a five-year, $3.4 billion AI cloud contract with NVIDIA and is also supporting a $9.7 billion Microsoft cloud deal at Childress, Texas. Those are not throwaway arrangements. They show a clear shift toward recurring revenue, which is music to the ears of investors tired of the boom-bust lunacy of pure mining economics.

The company is targeting 480MW of AI cloud capacity in 2026 and is aiming for $3.7 billion in annual recurring revenue by year-end. That recurring revenue target is especially important. Bitcoin mining is notoriously volatile because it depends on Bitcoin price, network difficulty, energy costs, and the halving cycle. AI cloud contracts, by contrast, can lock in longer-term cash flows if the company can actually deliver the infrastructure on time. That “if” is doing a lot of heavy lifting.

IREN is not the only miner trying to squeeze more value out of power and facilities. HIVE Digital is converting a data center in Boden, Sweden into a Tier-3 liquid-cooled HPC facility for 2,000 NVIDIA GPUs. Bitdeer is also making similar moves, including Tydal-2 in Norway, where 175MW of online crypto capacity is being converted to AI by Q4 2026.

For readers unfamiliar with the term, HPC stands for high-performance computing. It refers to powerful computing systems used for demanding workloads like AI training, research, and large-scale model inference. And liquid-cooled means the equipment is cooled with fluid rather than just air — important because AI hardware generates a ridiculous amount of heat, and nobody wants a data center that doubles as a toaster.

The upside is real, but so are the risks

The appeal of this pivot is obvious. If a company already controls power, land, and infrastructure, AI can offer a more predictable business model than mining Bitcoin block rewards. That is especially true when a miner can sign contracts with giant customers and turn capacity into a recurring revenue stream.

But there is a darker side to the AI infrastructure rush. This is capital-intensive, execution-heavy, and full of companies pretending that simply slapping “AI” on a press release creates value out of thin air. It does not. Data centers need to be built, GPUs need to be sourced, power needs to be secured, and contracts need to be honored. If buildouts slip or demand cools, margins can get shredded fast.

There is also a centralization concern worth keeping in mind. As more mining companies pivot toward AI, the winners may be the biggest players with the cheapest power and the best access to capital. That may be good business, but it is not exactly the decentralized utopia some crypto evangelists like to sell. In some cases, the “next big thing” is just another form of concentrated infrastructure power with shinier branding.

That does not make the trend bad. It just makes it real.

What this means for Bitcoin miners

Bitcoin mining still has a purpose, and for hard-money advocates it remains the native, uncompromising use case for proof-of-work infrastructure. But not every megawatt should be forced to chase block rewards if that same capacity can generate steadier returns elsewhere.

IREN’s move into Spain shows how miners are adapting to economic reality. Bitcoin mining revenue is under pressure. AI compute demand is surging. The market is rewarding infrastructure owners that can pivot from hashpower to hosted compute. That is not a betrayal of Bitcoin; it is a sign that the infrastructure built around Bitcoin can be more versatile than critics or zealots sometimes admit.

The key question is execution. Can IREN turn power and pipeline into reliable AI cloud services without getting bogged down by delays, capex overruns, or customer concentration? Can it scale in Europe as fast as demand seems to be growing? Can it do all that while still keeping the Bitcoin side of the business meaningful?

Those answers will matter more than any glossy AI narrative. The market does not care about slogans. It cares about delivered megawatts, connected racks, and revenue that actually shows up.

Key questions and takeaways

What did IREN acquire?

IREN acquired Ingenostrum, S.L. (Nostrum Group), a Spanish infrastructure company focused on power, development pipelines, and AI infrastructure growth.

Why does the deal matter?

It gives IREN 490MW of secured, grid-connected power, a local team, and its first European market for AI cloud infrastructure expansion.

Why are Bitcoin miners moving into AI?

Because Bitcoin mining revenue is under pressure, while AI cloud services revenue and long-term compute contracts can offer more stable cash flow.

Is IREN still a Bitcoin miner?

Yes, but it is increasingly becoming a hybrid Bitcoin mining and AI infrastructure company.

What does “grid-connected power” mean?

It means the power capacity is already tied into the electrical grid and can be used for data-center operations, which saves time and makes deployment much easier.

What is HPC?

HPC stands for high-performance computing, a category of computing designed for heavy workloads like AI training and large-scale data processing.

What is the biggest risk?

Execution risk. AI infrastructure is expensive, competitive, and easy to overhype. If projects slip or demand fails to match expectations, the numbers can get ugly quickly.

Is this good for Bitcoin?

Indirectly, yes. It shows that Bitcoin mining infrastructure has value beyond mining itself, even if some of that value is being redirected toward AI instead of hashpower.
