IREN delivered its first Horizon 1 AI data center to Microsoft on August 13, 2026, and achieved NVIDIA Exemplar Cloud status, marking a significant execution milestone under the companies’ five-year, $9.7 billion cloud services contract announced in November 2025. Horizon 1 is a 50-megawatt direct-to-chip liquid-cooled deployment at IREN’s Childress, Texas campus, the first of four identical 50MW facilities scheduled for delivery throughout 2026.
The rapid delivery reflects IREN’s vertically integrated model, which provides end-to-end control over data center design, engineering, and construction. Co-Founder and Co-CEO Daniel Roberts said the achievement demonstrates “the strength of our vertically integrated model and our ability to execute complex AI infrastructure projects at speed and scale,” and credited more than 3,000 site team members for the milestone.
NVIDIA Exemplar Cloud status, achieved after NVIDIA tested IREN’s GB300 NVL72 deployment, verifies that the infrastructure meets stringent performance, reliability, and scalability standards for demanding AI workloads. Since NVIDIA introduced the Exemplar Cloud program last year, six cloud partners have achieved the certification, including CoreWeave, Crusoe, Lambda, and others.
The Horizon 1 delivery advances IREN’s broader expansion targets: 480 megawatts of gross AI Cloud capacity by the end of 2026, and 1.2 gigawatts by 2027. The company also signed $2.8 billion in new multi-year AI Cloud services contracts with leading AI developers and raised its year-end 2026 AI Cloud annualized recurring revenue target, according to statements made earlier in August.
The milestone carries strategic weight in a competitive AI infrastructure market. In 2026, hyperscaler capital expenditure on data centers is projected to reach $697 billion globally, with AI workloads expected to represent 28 percent of the data center market by 2027, according to J.P. Morgan and industry analysts. IREN’s execution on the Microsoft contract—particularly the acceptance of Horizon 1—reduces execution risk on the full $9.7 billion agreement and validates the company’s ability to deliver large-scale, specialized AI infrastructure.
The delivery also positions IREN within a broader ecosystem of neocloud providers competing for enterprise and hyperscaler AI infrastructure contracts. Earlier in August, Super Micro Computer landed a gigawatt-scale AI data center deal with SpaceX and xAI, while CoreWeave and other specialized cloud providers continued to secure large commitments. IREN’s combined execution on Horizon 1 and its new $2.8 billion in contracts underscore the scale of demand for purpose-built AI infrastructure.
