Microsoft has inked a multibillion-dollar deal with Australian data center operator IREN to supercharge its AI cloud capabilities over the next five years.
Quick Summary – TLDR:
- Microsoft signed a $9.7 billion deal with Sydney-based IREN for AI cloud infrastructure.
- The deal includes access to Nvidia’s GB300 GPUs, delivered via a $5.8 billion agreement with Dell.
- Microsoft prepaid 20 percent and will be IREN’s largest customer, with $1.94 billion in expected annualized revenue.
- The move helps Microsoft bypass the delays and costs of building its own data centers.
What Happened?
Microsoft has partnered with IREN in a high-stakes bid to solve the current shortage in computing power needed for artificial intelligence workloads. The five-year deal, valued at $9.7 billion, will provide Microsoft with access to high-performance Nvidia Blackwell GB300 GPUs via IREN’s cloud infrastructure, enabling it to keep pace with the growing AI boom.

Microsoft’s AI Expansion Strategy
With artificial intelligence demand outpacing supply, Microsoft is aggressively investing in external cloud infrastructure to avoid delays in rolling out AI products and services. IREN will deliver access to Nvidia’s powerful GPUs through data centers located in Childress, Texas, where new liquid-cooled facilities are being built to handle the intense processing needs of modern AI models.
Key details of the deal include:
- $5.8 billion equipment agreement between IREN and Dell Technologies to supply Nvidia GPUs.
- GPUs will be deployed in phases through 2026.
- The campus in Childress is expected to add about 200 megawatts of IT capacity.
- Microsoft made a 20 percent prepayment on the deal, which IREN will use to finance part of its GPU acquisition.
This agreement positions Microsoft as IREN’s largest customer, projecting $1.94 billion in annualized revenue over the contract’s five-year term. If IREN fails to meet delivery timelines, Microsoft has the option to terminate the contract.
Crypto Miners Turned AI Cloud Titans
IREN joins a growing list of former cryptocurrency mining firms transitioning into AI data infrastructure providers. Their expertise with GPU-heavy operations and existing energy-rich facilities makes them well suited to the AI industry’s needs. Others like CoreWeave and HIVE have also secured multi-billion dollar deals in this space.
The rise of these so-called “neocloud” companies reflects a shift in the market, where AI is outpacing crypto in value and viability. IREN’s stock alone has surged over 500 percent in 2025, with shares spiking nearly 25 percent on the announcement of the Microsoft deal.
Meanwhile, Microsoft continues to strike similar partnerships. In addition to the IREN deal, it recently signed a $17.4 billion agreement with Nebius Group and another multibillion-dollar agreement with AI infrastructure startup Lambda.
Navigating Capacity Shortages and Cost Pressures
Microsoft’s strategic partnerships allow it to avoid heavy capital spending on building new facilities and buying soon-to-be outdated hardware. Instead of securing land, power, and permits for new data centers, it is leveraging third-party operators like IREN who already have scalable infrastructure.
Tech giants including Microsoft and Amazon have acknowledged during recent earnings calls that capacity shortages are a real bottleneck to AI deployment. These partnerships aim to fix that by quickly bringing GPU power online.
At the same time, Microsoft’s involvement in the AI race goes far beyond infrastructure. The company holds a 27 percent stake in OpenAI, creator of ChatGPT, and retains IP rights to GPT until 2032. It is also entitled to 20 percent of OpenAI’s revenue until it reaches artificial general intelligence. OpenAI is expected to generate $12.7 billion in revenue this year.
SQ Magazine’s Takeaway
I think Microsoft’s move here is one of the clearest signals yet that we’re just getting started with the AI cloud race. This is not about tomorrow. It’s about catching up with demand that’s already here today. And instead of slowly building new data centers, Microsoft is doing something smarter: buying time and power by plugging into infrastructure that already exists. Deals like these are shaping the future of AI, and it’s fascinating to see former crypto players like IREN leading the charge. If you’re watching where the AI cloud money is going, this is a headline worth remembering.
