IREN Expands AI Infrastructure with Mirantis Acquisition

IREN has announced a $625 million all-stock acquisition of infrastructure software provider Mirantis, a move designed to transition the company from a power-focused landlord into a full-stack AI cloud operator [1]. This strategic expansion coincides with the energization of the company’s 1.4-gigawatt Sweetwater 1 site in Texas, marking a significant milestone in its pivot away from its origins as a Bitcoin mining startup [1].

Key takeaways

• The $625 million acquisition of Mirantis provides IREN with the k0rdent Kubernetes platform and access to an enterprise customer base of over 1,500 companies [1][2].
• IREN has energized the first phase of its Sweetwater, Texas, campus, which is designed to host up to 700,000 liquid-cooled Nvidia graphics cards [1][2].
• The company is currently supported by a $1.94 billion average annual contract with Microsoft, backed by $3.6 billion in GPU financing [1].
• IREN aims to reach a $3.4 billion annualized revenue run-rate by the end of 2026 as it shifts its business model toward AI infrastructure [1].

Integrating Software and Power Capacity

The acquisition of Mirantis is intended to accelerate IREN’s ability to deploy customer workloads by integrating specialized software with its existing hardware infrastructure [2]. Mirantis, which previously raised $220 million from investors including Intel and Goldman Sachs, offers the k0rdent platform, which allows administrators to manage multiple Kubernetes clusters through a centralized interface [2]. This software includes features specifically for AI, such as the ability to split graphics cards into virtual chips to improve hardware utilization and automated inference autoscaling [2].

IREN’s infrastructure growth is anchored by its Sweetwater campus, an 1,800-acre site in Texas with access to 2 gigawatts of electricity [2]. By utilizing campuses with existing power delivery infrastructure, the company aims to avoid the delays associated with building data centers from scratch [2]. While Bitcoin mining currently accounts for 91% of IREN's revenue, the company is actively reorienting its operations to compete directly with AI cloud providers such as CoreWeave and Nebius [1].

Why it matters

The transition to an AI-first business model carries significant operational requirements for IREN. The company must now successfully integrate the Mirantis software stack with its bare-metal GPU offerings to attract enterprise clients beyond its anchor contract with Microsoft [1]. Market observers are closely monitoring the timing of revenue recognition from these Microsoft deployments and the company's ability to execute its expansion plans, which include a 140,000 GPU rollout [1]. As IREN moves forward, its financial performance will be measured against its $3.4 billion annualized revenue target for 2026, a goal that relies on the continued development of its 3-gigawatt grid-connected portfolio across Texas, Oklahoma, and British Columbia [1].
