A Landmark Deal Strengthening IREN’s Position in the AI Cloud Market

Under the agreement announced November 3, 2025, IREN will provide Microsoft with access to NVIDIA GB300 GPUs over a five-year term, with the total contract value reaching approximately $9.7 billion. The deal includes a significant 20% prepayment from Microsoft, providing IREN with immediate capital to support deployment. To fulfill the contract, IREN has entered into a separate agreement with Dell Technologies to purchase the GPUs and ancillary equipment for approximately $5.8 billion, which includes deployment services, servers, InfiniBand infrastructure, cabling, software, and licensing costs.

The GPUs will be deployed in phases throughout 2026 at IREN’s 750MW campus in Childress, Texas, in conjunction with new liquid-cooled data centers that will collectively support 200MW of critical IT load across Horizon 1-4 phases. IREN plans to finance the substantial capital expenditures through a combination of existing cash reserves, customer prepayments, operating cash flows, and additional financing initiatives. The company recently closed a $1.0 billion convertible notes offering in October 2025, which provides additional financial flexibility for this massive infrastructure buildout.

Daniel Roberts, Co-Founder and Co-CEO of IREN, emphasized that the agreement validates IREN’s position as a trusted AI Cloud services provider and opens access to a new customer segment among global hyperscalers. Jonathan Tinter, President of Business Development and Ventures at Microsoft, noted that IREN’s expertise in building and operating fully integrated AI cloud infrastructure, combined with their secured power capacity, makes them a strategic partner for delivering cutting-edge AI infrastructure to Microsoft’s customers.
