Microsoft's $9.7 Billion Data Centre Partnership with IREN and Nvidia Chips

Microsoft’s Strategic Expansion in AI Infrastructure

Microsoft has entered a landmark $9.7 billion agreement with IREN, a data-centre operator, to gain access to advanced Nvidia chips and secure additional data-centre capacity. This partnership aims to alleviate computing power constraints, a critical bottleneck for AI services like ChatGPT, and support Microsoft’s growing demand for AI workloads. The deal also includes an expanded collaboration with Lambda, an AI cloud startup, to deploy infrastructure using Nvidia hardware.

Key Details of the IREN Partnership

• Deal Value and Allocation:

  • Microsoft will invest $9.7 billion, with $5.8 billion allocated to acquiring Nvidia’s GB300 chips and related equipment.
  • The agreement spans five years, allowing Microsoft to avoid building new data centres or sourcing additional power, which are costly and time-consuming.

• IREN’s Role and Benefits:

  • IREN’s North American data centres have a total capacity of 2,910 megawatts, with a 750-megawatt campus in Childress, Texas, set to deploy Nvidia processors in stages through 2026.
  • The company plans to introduce liquid-cooled data centres capable of supporting 200 megawatts of IT capacity, enhancing energy efficiency.
  • IREN’s stock surged 24.7% to a record high following the announcement, reflecting investor confidence.

• Dell’s Involvement:

  • Dell will supply IREN with Nvidia GB300 chips and equipment. Microsoft’s prepayment will cover part of IREN’s $5.8 billion agreement with Dell.
  • A clause allows Microsoft to terminate the deal if delivery goals are unmet, mitigating risks of hardware obsolescence.

Broader Industry Context and Competition

• Neocloud Providers:

  • Companies like CoreWeave and Nebius Group have thrived by offering cloud services built on Nvidia chips. Microsoft recently signed a $17.4 billion deal with Nebius for infrastructure access, underscoring the sector’s scramble for hardware.

• Lambda Partnership:

  • Microsoft and Lambda, an AI cloud startup, announced a multibillion-dollar agreement to deploy AI infrastructure using Nvidia hardware.
  • The deal includes tens of thousands of Nvidia GPUs, including the GB300 NVL72 systems, first introduced in 2025.
  • Lambda’s CEO, Stephen Balaban, emphasized the partnership as a “phenomenal next step” in their eight-year collaboration.

Impact on AI Workloads and Market Trends

• Microsoft’s AI Infrastructure:

  • The partnership enables Microsoft to scale AI workloads beyond traditional data centres. In October 2025, Microsoft launched its first Nvidia GB300 NVL72 cluster, expanding its AI capabilities.
  • The deal addresses capacity shortages that have hindered growth in the AI sector, as highlighted in recent earnings reports by major tech firms.

• Market Dynamics:

  • IREN’s market value reached $16.52 billion as of its previous close, up over sixfold this year. Dell’s stock also rose slightly, reflecting indirect benefits from the partnership.
  • The agreement highlights the growing competition for computing power as AI adoption accelerates globally.
