IREN Limited just wrote another very large check to Dell Technologies. The company, which not long ago was primarily known as a Bitcoin mining operation, has signed a $1.6 billion purchase agreement with Dell for air-cooled systems to support its growing AI cloud business.

The deal is the latest in a string of multi-billion-dollar hardware commitments that signal how aggressively IREN is repositioning itself as an AI infrastructure company.

A spending spree measured in billions

This $1.6 billion agreement doesn’t exist in a vacuum. It’s actually an addition to an already enormous procurement relationship between IREN and Dell.

The two companies previously finalized a $5.8 billion deal for GPUs and supporting equipment, including liquid-cooled systems designed for IREN’s data center campus in Childress, Texas. A separate agreement from March 2026 added roughly $3.5 billion more to their hardware purchasing plans, covering over 50,000 NVIDIA B300 GPUs.

The company is building toward a fleet of approximately 150,000 GPU units.

From Bitcoin blocks to GPU racks

IREN Limited, formerly known as Iris Energy Limited, made its name running renewable-powered Bitcoin mining operations. The pivot to AI cloud infrastructure became official on November 3, 2025, when the company disclosed a multi-year contract with Microsoft valued at approximately $9.7 billion.

That Microsoft deal is the anchor tenant arrangement that makes all of this Dell spending make sense. IREN is essentially building out the physical compute infrastructure that Microsoft will use for its AI workloads, deploying NVIDIA GB300 GPUs at the Childress, Texas facility.

IREN has secured over 4.5 GW of renewable power capacity for its data centers.

What this means for investors

IREN’s stock has hit record highs following these AI contract announcements. The company has essentially locked in a nearly $10 billion revenue pipeline from Microsoft alone, backstopped by billions more in hardware investment.

Microsoft represents an outsized share of IREN’s forward revenue, meaning any change in Microsoft’s AI infrastructure strategy could have an outsized impact on IREN’s financial outlook.
