IREN delivered its first 50MW direct-to-chip liquid-cooled AI data center to Microsoft and achieved NVIDIA Exemplar Clou

IREN Limited announced on August 13, 2026, that Horizon 1 has been delivered to and accepted by Microsoft, and that IREN has achieved NVIDIA Exemplar Cloud status on NVIDIA GB300 NVL72. Horizon 1 is the first of four 50MW IT-load direct-to-chip liquid-cooled AI cloud deployments scheduled for delivery to Microsoft at IREN's Childress, Texas campus in 2026. These deployments are part of a five-year cloud services contract valued at $9.7 billion announced in November 2025.

The rapid delivery reflects IREN's vertically integrated operating model, which provides end-to-end control over the design, engineering, and construction of data centers supporting its GPU deployments. IREN's Exemplar Cloud status was achieved following NVIDIA's testing of the GB300 NVL72 deployment at Horizon 1. The designation demonstrates IREN's ability to support demanding AI workloads with performance, reliability, and scale.

IREN continues to target a broader expansion to 480MW of gross AI cloud capacity in 2026 and 1.2GW of gross AI cloud capacity in 2027. Daniel Roberts, Co-Founder and Co-CEO of IREN, commented: "Delivering Horizon 1 demonstrates the strength of our vertically integrated model and our ability to execute complex AI infrastructure projects at speed and scale. I want to congratulate and thank the more than 3,000 people across our site team whose expertise, commitment and execution made this milestone possible. We look forward to building on this momentum with Microsoft as we work to deliver Horizons 2-4 later this year."

IREN is a vertically integrated AI cloud platform delivering data centers, compute, and software for AI training and inference, with an expansive portfolio of land and grid-connected power in renewable-rich regions across North America, Europe, and APAC.
