In a significant move to overcome the global shortage of high-performance computing, Microsoft has entered into a five-year, $9.7 billion agreement with data-center operator IREN to secure access to advanced Nvidia processors. The deal is designed to expand Microsoft’s cloud capacity for artificial intelligence services, addressing a critical bottleneck that has constrained the tech giant’s ability to fully capitalize on the booming AI market. This partnership allows Microsoft to rapidly scale its AI infrastructure without the delays and capital expenditure associated with building new data centers from the ground up.
The arrangement underscores a growing industry trend where major technology companies are partnering with specialized data-center operators, or “neoclouds,” to meet the voracious demand for AI computing power. Under the terms of the contract, IREN, an Australian company that began in bitcoin mining, will provide Microsoft with dedicated AI cloud capacity powered by Nvidia’s latest chips. The deal represents a strategic transformation for IREN, shifting its business model toward providing critical infrastructure for global technology leaders and securing a stable, long-term revenue stream. For Microsoft, it sidesteps the hurdles of securing both land and power for new facilities, while also mitigating the financial risk of purchasing vast quantities of chips that quickly depreciate as technology advances.
A Strategic Partnership for AI Expansion
The collaboration is a direct response to the computing crunch that has impacted major tech companies. Microsoft has experienced surging demand for its AI-powered tools, including Azure AI and GitHub Copilot, which require immense computational resources. Company executives recently acknowledged that this capacity shortage is expected to persist into at least mid-2026. By leasing capacity from IREN, Microsoft can more quickly deploy resources to meet customer needs and maintain its competitive edge in the AI sector. The five-year term provides a medium-term solution to the ongoing supply chain challenges for AI hardware.
This model of leasing specialized AI cloud services is becoming increasingly vital. Jonathan Tinter, president of business development and ventures at Microsoft, highlighted IREN’s specialized capabilities as a key factor in the partnership. “IREN’s expertise in building and operating a fully integrated AI cloud — from data centers to GPU stack — combined with their secured power capacity makes them a strategic partner,” Tinter stated. This approach allows Microsoft to be more agile, adding capacity in line with demand without being locked into massive, long-term capital projects for every expansion. The deal is expected to unlock new growth opportunities for both companies by serving a broader customer base.
Financial and Contractual Framework
The agreement is valued at approximately $9.7 billion over its five-year duration and is expected to generate about $1.94 billion in annualized revenue for IREN once fully implemented. As a key component of the deal, Microsoft will make a 20% prepayment to IREN, providing immediate capital for the massive hardware procurement required. This prepayment structure demonstrates a significant commitment from Microsoft and de-risks the initial investment for IREN.
To fulfill the contract, IREN has concurrently signed an agreement with Dell Technologies to purchase approximately $5.8 billion worth of GPUs and associated equipment. The order specifically includes Nvidia’s advanced GB300 accelerator systems, which are designed for high-intensity AI workloads. The cash from Microsoft’s prepayment will help finance a portion of this large-scale hardware purchase from Dell. The contract includes clauses that protect Microsoft’s investment, allowing the company to terminate the agreement if IREN fails to meet specified hardware delivery and deployment timelines.
Infrastructure and Deployment Timeline
The core of the new AI computing capacity will be built out at IREN’s 750-megawatt campus in Childress, Texas. The Nvidia processors are scheduled for a phased deployment through 2026. This gradual rollout allows for capacity to come online incrementally, aligning with Microsoft’s evolving needs and the complex logistics of installing and commissioning advanced server architecture. The Childress facility will feature new liquid-cooled data centers designed to handle the thermal demands of high-density GPU clusters, delivering an estimated 200 megawatts of critical IT capacity.
Expanding Beyond a Single Campus
While the Texas campus is the focal point of this deal, it represents only a fraction of IREN’s total operational footprint. The company operates multiple data centers across North America, with a total power capacity of 2,910 megawatts. Notably, IREN’s facilities are powered entirely by renewable energy, a factor that aligns with Microsoft’s corporate sustainability goals. According to IREN’s CEO, Daniel Roberts, the Microsoft deal will utilize about 10% of the company’s total capacity, leaving substantial room to sign additional contracts with other hyperscalers and AI firms.
IREN’s Pivot to AI Cloud Services
This agreement marks a pivotal transformation for IREN, which originally built its business around cryptocurrency mining. Like several other companies in the “neocloud” sector, IREN has successfully diversified its infrastructure to cater to the AI industry. These companies are leveraging their expertise in building and managing large-scale, power-intensive computing facilities to fill a crucial gap in the market. By transitioning from a volatile industry like bitcoin mining to providing stable, long-term AI infrastructure for one of the world’s largest companies, IREN achieves a new level of industry validation and financial stability.
The market has responded with strong optimism to this strategic shift. Following the announcement, IREN’s Nasdaq-traded shares surged more than 20% in premarket trading. This jump reflects investor confidence that the Microsoft agreement is a game-changing event for the company. It repositions IREN as a key infrastructure provider in the AI ecosystem, which has seen explosive growth, propelling companies like Nvidia to multi-trillion-dollar valuations. CEO Daniel Roberts noted that IREN has been in discussions with several major hyperscalers, viewing them as “natural partners” as their compute requirements have grown alongside IREN’s capabilities.
Market Implications and Industry Context
The Microsoft-IREN deal highlights a broader shift in how cloud infrastructure is provisioned. Hyperscale companies like Microsoft, Meta, and others are increasingly turning to specialized operators such as IREN, CoreWeave, and Nebius Group to supplement their own data center capacity. This strategy offers several advantages: it is faster than building new facilities, requires less upfront capital, and provides flexibility in a rapidly evolving hardware landscape. Microsoft itself has engaged in other large-scale leasing contracts, including a $17.4 billion deal with Nebius Group earlier in the year.
The intense demand for AI processing has created a distinct class of infrastructure providers that focus exclusively on deploying and managing massive GPU clusters. These neoclouds are becoming an indispensable part of the AI supply chain. The market reaction extended beyond IREN, with shares of Dell Technologies also rising 5% on the news of its role as the primary hardware supplier for the deal. This ripple effect demonstrates the interconnected nature of the AI hardware ecosystem, where a single large-scale agreement can create significant value for multiple partners involved in delivering the final computing product.
