IREN seals $1.6B Dell deal to power its growing AI cloud infrastructure

Not long ago, IREN Limited was primarily a Bitcoin mining company. Today, it signs billion-dollar hardware agreements at a pace that few purpose-built cloud operators have matched. The latest move is a $1.6 billion purchase agreement with Dell Technologies covering air-cooled systems for its expanding AI cloud platform.

To understand the scale of what IREN is building, that $1.6 billion figure needs context. It sits on top of a $5.8 billion deal with Dell for GPUs and liquid-cooled systems destined for its Childress, Texas cloud campus, and a separate March 2026 agreement worth roughly $3.5 billion covering more than 50,000 NVIDIA B300 GPUs. Across these three agreements alone, IREN has committed over $10 billion to Dell for cloud hardware. The company is working toward a total fleet of approximately 150,000 GPU units across its cloud infrastructure.

The strategic logic behind all of this spending traces back to November 2025, when IREN disclosed a multi-year cloud services contract with Microsoft valued at approximately $9.7 billion. That arrangement serves as the anchor tenant for the Childress facility, with Microsoft consuming cloud compute capacity for AI workloads running on NVIDIA GB300 GPUs. In practical terms, IREN builds and operates the cloud infrastructure, while Microsoft fills it with production AI workloads.

IREN also holds over 4.5 gigawatts of secured renewable power capacity across its cloud data center portfolio, which matters both for operating economics and for the sustainability requirements that large cloud customers increasingly attach to infrastructure contracts.

The company’s stock has reached record highs following these announcements, reflecting investor confidence in the revenue pipeline the Microsoft cloud contract represents. A locked-in $9.7 billion customer relationship provides unusual revenue visibility for a cloud operator of IREN’s size.

The concentration risk deserves honest attention, though. Microsoft drives the bulk of IREN’s projected cloud revenue, so the company’s financial path forward tracks closely with how aggressively Microsoft continues investing in AI cloud infrastructure. If that investment pace slows or priorities shift, IREN absorbs the impact more sharply than a more diversified cloud operator would.

For now, the build continues.
