Microsoft Signs $9.7 Billion AI Deal with IREN to Expand GPU Infrastructure
Microsoft has signed a massive $9.7 billion agreement with data center operator IREN Ltd., marking another major step in its race to secure more artificial intelligence computing capacity. The five-year deal will provide Microsoft with access to NVIDIA’s high-performance AI chips through IREN’s growing network of data centers, including its massive Childress, Texas campus.
A Strategic Move to Ease AI Compute Shortages
The deal will allow Microsoft to use NVIDIA GB300 GPUs and other hardware hosted by IREN without having to build new data centers or invest in additional power infrastructure. To fulfill the contract, IREN will purchase $5.8 billion worth of GPUs and related equipment from Dell Technologies, which will be deployed in phases through 2026.
In a filing, IREN confirmed that Microsoft will prepay 20% of the total contract value — a sign of strong commitment and urgency to ramp up AI compute capacity. The partnership covers 200 megawatts of capacity, backed by liquid-cooled systems optimized for AI workloads.
“Together with IREN, Microsoft is delivering cutting-edge AI infrastructure for our customers,†said Jonathan Tinter, Microsoft’s President of Business Development and Ventures.
“IREN’s expertise in building and operating fully integrated AI clouds, from data centers to GPU stacks, makes them a key strategic partner.â€Also Read: Fake Retail Networks in 2025: How to Spot and Avoid Online Shopping Scams
IREN’s Game-Changing Moment
The announcement sent IREN’s stock soaring over 20%, as analysts called the deal a “game changer.â€
Cantor Fitzgerald’s Brett Knoblauch noted that the partnership gives IREN an “anchor tenant†in Microsoft — a critical milestone that boosts its reputation as a top-tier AI infrastructure provider.
The deal represents a major pivot for IREN, which has transformed from a Bitcoin mining company into a high-performance computing (HPC) and AI infrastructure provider. With over 2,900 megawatts of total data center capacity across North America — all powered by renewable energy — IREN is now positioning itself among the world’s largest AI data center operators.
Microsoft’s Expanding AI Network
This isn’t Microsoft’s only move to expand access to AI computing. Just weeks ago, the company signed another multi-year agreement with Nebius Group NV, a neocloud provider, in a deal worth nearly $20 billion. Both partnerships underline Microsoft’s aggressive strategy to overcome the AI compute shortage that has limited its ability to capitalize on the AI boom fully.
“Our AI capacity crunch will likely stretch into mid-2026,†said Amy Hood, Microsoft CFO, during last week’s earnings call.
“These partnerships allow us to scale faster without the delays and capital costs of new builds.â€
A Boost for AI and Data Center Markets
The Microsoft–IREN deal is also a major win for the hardware ecosystem. NVIDIA (NVDA) stock rose over 2.8%, and Dell (DELL) shares climbed as the company prepares to supply billions in GPU hardware.
IREN’s Childress campus — soon to host these GPUs — will become one of the largest AI compute hubs in the United States, featuring liquid-cooled data centers and sustainable energy solutions to support next-gen AI training and inference workloads.
As AI demand continues to outpace supply, partnerships like these highlight how Big Tech companies are leaning on specialized data-center operators to meet unprecedented computational needs. For IREN, the Microsoft deal marks its entrance into the AI big leagues — and potentially sets the stage for even larger collaborations in the years ahead.
