Summary
Blue Owl Capital, in partnership with PIMCO, has led a $2.4 billion debt facility for IREN to finance the expansion of its Mackenzie AI data center site. The facility carries a fixed interest rate of 9.0% and covers approximately 90% of the GPU capital expenditure required for the project, according to multiple sources including IREN's FY2026 financial results and announcements from the financing parties.
This transaction reflects the growing institutional appetite for large-scale AI infrastructure financing. Blue Owl has emerged as a major player in this space, leveraging its Digital Infrastructure Fund to deploy capital across frontier AI compute facilities. The inclusion of PIMCO, one of the world's largest fixed-income managers, as co-lead underscores the investment-grade quality of the financing and broad institutional confidence in IREN's operational model and contract base.
The $2.4 billion facility is part of a broader financing ecosystem supporting IREN's growth. The company has simultaneously closed a $3.65 billion investment-grade GPU financing facility to support delivery of AI cloud services, particularly related to its Microsoft AI Cloud contract. This multi-facility structure suggests IREN is accessing different segments of the capital markets—including both asset managers and traditional debt capital markets—to fund its expansion across multiple data center sites.
The 9.0% fixed rate provides IREN with long-term financing certainty at a time when AI infrastructure investments are attracting significant capital flows. The debt structure, covering 90% of capex, is consistent with infrastructure project financing standards and allows IREN to maintain flexibility for equity deployment and operational cash management. The Mackenzie financing demonstrates that institutional investors view AI compute infrastructure as a core long-term asset class with predictable cash flows backed by hyperscaler commitments.
