On August 12, IREN Ltd rose 5.33% overnight, trading at $41.91/share, with turnover of $2.0452 million. The rally was driven by news that Anthropic signed a $9.1 billion, 20-year cloud computing contract with Riot Platforms, underscoring sustained high-pressure demand from AI enterprises for compute supply and lifting the broader neocloud sector.

Sector-wide momentum was evident during the session, with NEBIUS up 4.95%, Riot up 4.33%, Hut 8 up 3.64%, and CoreWeave up 2.42%, reflecting strong linkage effects. IREN itself holds $2.8 billion in AI compute contracts and recently completed its acquisition of Mirantis to strengthen the software layer of its vertically integrated AI cloud platform. Earlier in July, the company raised its year-end AI cloud annualized run-rate revenue target to over $4 billion from $3.7 billion, with approximately 85% now under contract. These fundamentals position IREN as a continued beneficiary of accelerating AI infrastructure spending spillover into independent compute operators.
