On August 13, IREN Ltd rose 5.32% in regular trading, trading at $46.455/share, with turnover of $3.67 billion. The rally was driven by the company's announcement that it has completed and delivered Horizon 1 — a 50-megawatt AI computing facility — to Microsoft.
The delivery is part of a five-year, $9.7 billion cloud services contract with Microsoft announced in November 2025. Horizon 1 is a direct-to-chip liquid-cooled data center designed to support high-performance AI computing, equipped for NVIDIA's GB300 NVL72 platform. Simultaneously, IREN achieved NVIDIA Exemplar Cloud status following NVIDIA's testing of its GB300 NVL72 deployment, marking a significant endorsement from the leading chip manufacturer of IREN's AI cloud delivery capabilities.
The milestone comes amid broader tailwinds for the neocloud sector, including Anthropic's $9.1 billion long-term compute deal with Riot Platforms and NVIDIA's $500 billion AI infrastructure financing platform with six major financial institutions. IREN itself holds $2.8 billion in AI compute contracts and targets expanding AI cloud capacity to 480MW by year-end and 1.2GW by 2027.
