IREN Delivers First 50MW AI Data Center to Microsoft, Achieves NVIDIA Exemplar Status
The Australian AI infrastructure firm completed Horizon 1 at its Texas campus under a $9.7 billion contract, earning recognition for its GB300 NVL72 deployment performance.
Microsoft Accepts First Horizon Deployment
IREN Limited disclosed that it has delivered Horizon 1, its first 50MW AI Cloud data center, to Microsoft and achieved NVIDIA Exemplar Cloud status on the GB300 NVL72 platform, according to an 8-K filing submitted August 13, 2026.
Horizon 1 represents the first of four 50MW direct-to-chip liquid cooled AI Cloud deployments scheduled for delivery to Microsoft at IREN's Childress, Texas campus in 2026 under a five-year, $9.7 billion cloud services contract announced in November 2025 (8-K filing, 2026-08-13).
The Australian company, which trades on NASDAQ with a market capitalization of approximately $16 billion, positions itself as a vertically integrated AI Cloud platform delivering data centers, compute and software for AI training and inference.
NVIDIA Exemplar Recognition
IREN's Exemplar Cloud status was achieved following NVIDIA's testing of its NVIDIA GB300 NVL72 deployment at Horizon 1. The designation "demonstrates IREN's ability to support demanding AI workloads with performance, reliability and scale," according to the filing (8-K filing, 2026-08-13).
The Exemplar Cloud program represents NVIDIA's certification for cloud service providers meeting stringent performance benchmarks on its latest-generation AI hardware.
Execution Timeline and Capacity Targets
Co-Founder and Co-CEO Daniel Roberts attributed the rapid delivery to "the strength of our vertically integrated model and our ability to execute complex AI infrastructure projects at speed and scale" (8-K filing, 2026-08-13). The company's vertically integrated approach provides "end-to-end control across design, engineering and construction of the data centers supporting its GPU deployments," according to the filing.
Roberts acknowledged the contribution of "more than 3,000 people across our site team" involved in the Horizon 1 deployment (8-K filing, 2026-08-13).
IREN continues to target expansion to 480MW (gross) AI Cloud capacity in 2026 and 1.2GW (gross) AI Cloud capacity in 2027 (8-K filing, 2026-08-13). These capacity targets would represent significant scaling from the current 50MW IT load deployment.
Infrastructure and Geographic Footprint
The company describes its platform as "underpinned by its expansive portfolio of land and grid-connected power in renewable-rich regions across North America, Europe and APAC" (8-K filing, 2026-08-13). The Childress, Texas campus represents IREN's North American deployment hub for the Microsoft contract.
The remaining three Horizon facilities are scheduled for delivery to Microsoft later in 2026, though specific completion dates were not disclosed in the filing.
