Bitcoin miner-turned-AI-infrastructure provider IREN secured $3.65 billion in financing on Monday, backed by its cloud computing contract with Microsoft. The financing facility received investment-grade ratings of A from Fitch and A(low) from DBRS, which IREN claims is the highest publicly rated investment-grade GPU financing announced and the first GPU financing in the U.S. private placement market. The high ratings enabled IREN to secure a blended borrowing cost of 6%, with the financing consisting of a $2.1 billion U.S. private placement and a $1.55 billion delayed-draw loan.
IREN Structures $3.65 Billion Financing with Investment-Grade Ratings
The $3.65 billion financing, combined with customer prepayments from Microsoft, funds approximately 96% of the $5.81 billion in GPU capital tied to the contract, according to IREN. Co-founder and co-CEO Daniel Roberts stated that securing investment-grade financing on these terms reflects both the quality of the company's customer contracts and the fact that IREN owns the data center infrastructure these GPUs run in. The financing closed weeks after IREN completed a $3 billion convertible notes offering.
IREN Expands AI Infrastructure Following Microsoft and Nvidia Partnerships
IREN signed its multibillion-dollar AI cloud agreement with Microsoft in late 2025 and later secured a partnership with Nvidia with plans for a large-scale AI compute buildout. Bernstein analysts described IREN's AI expansion as capital-intensive and dependent on access to flexible financing in a note last month. The analysts pointed to IREN as one of the best-positioned bitcoin miners to benefit from AI infrastructure demand, citing its expanding power footprint and AI compute contracts.
IREN Shares Trade Down Following Recent Highs
IREN shares were down nearly 2% to $62.30 in the first trading hour on Monday after reaching a more than six-month high above $68 last week.
