IREN secures $3.65B GPU loan for Microsoft AI infrastructure buildout

IREN Limited closed a $3.65 billion investment-grade financing facility to fund Nvidia GPU purchases for a Microsoft AI cloud contract, the first GPU-backed debt deal to receive public investment-grade ratings in the US private placement market. The facility, secured against the GPUs and associated Microsoft cash flows, received A and A(low) ratings from Fitch and DBRS respectively.

"This financing reflects both the quality of our customer contracts and the fact that we own the data center infrastructure these GPUs run in," Daniel Roberts, Co-Founder and Co-CEO of IREN, said. "That combination broadens our access to institutional capital and lowers our cost of capital as we scale."

The capital structure comprises a $2.1 billion US private placement at a fixed rate equivalent to SOFR plus 2.13 percent and a $1.55 billion delayed draw term loan at SOFR plus 2.25 percent, both maturing Dec. 31, 2031. IREN achieved a blended cost of debt of 6 percent after hedging, with the facility funding $5.59 billion of the $5.81 billion total GPU capital expenditure under the Microsoft contract — roughly 96 percent — at an average financing cost of 3.31 percent when including customer prepayments. Goldman Sachs and J.P. Morgan served as joint lead managers and arrangers.

The deal supports a thesis gaining traction across Wall Street: Bitcoin miners with existing power and data center assets can pivot to AI cloud services at a fraction of the cost of greenfield construction. IREN, which began as a Bitcoin mining operator, now targets 480 megawatts of AI Cloud capacity by the end of 2026. The company has stacked multiple agreements this year — a $9.7 billion Microsoft contract announced in November, a $1.6 billion Dell Technologies deal for Nvidia Blackwell systems, and a commitment from Nvidia itself to invest up to $2.1 billion in IREN's infrastructure buildout.

Project Finance Structure Shields Parent Company

The financing resembles project finance more than traditional corporate debt. IE US Hardware 3 LLC, a ring-fenced IREN subsidiary, borrowed against the GPU assets and the revenue stream from the Microsoft service agreement, insulating creditors from IREN's broader corporate risk. The parent company issued only limited guarantees tied to managed services delivery and potential payment gaps if Microsoft cancels any GPU services tranche.

This structure creates a potential template for other crypto-native infrastructure operators seeking to fund AI transitions. By securing debt against contracted cash flows rather than corporate balance sheets, IREN accessed a broader investor base — including insurance companies and asset managers — at investment-grade pricing that would typically be unavailable to companies with Bitcoin mining exposure. The subsidiary also implemented hedging instruments to mitigate interest rate and electricity cost volatility.

IREN's Pivot Reshapes the AI Cloud Competitive Landscape

IREN's rapid repositioning reflects a broader shift in the AI infrastructure market. Hyperscalers like Microsoft are signing long-term capacity agreements with non-traditional providers to secure scarce GPU compute, while Nvidia benefits from multiple demand channels as cloud GPU rental prices rise. Nvidia CFO Colette Kress said H100 rental prices have climbed about 20 percent year-to-date, while A100 pricing has risen nearly 15 percent.

IREN shares traded near $62.07, down 2.3 percent on the day, giving the company a market capitalization of about $22.7 billion. Wall Street consensus rates the stock a Buy with a $99 price target, implying roughly 60 percent upside. The company projects annualized run-rate revenue of $4.4 billion once its Blackwell systems are commissioned in early 2027, up from $3.7 billion previously.

For investors, the key question is whether IREN can execute on its 480 MW capacity target without delays. The Dell Blackwell systems are scheduled for commissioning in early 2027, and any slippage would leave the company carrying elevated capital expenditure before contracted cash flows arrive. Nvidia's up-to-$2.1 billion investment commitment provides a buffer, but the financing structure ultimately depends on Microsoft fulfilling its payment obligations under the GPU services agreement. IREN trades at roughly 5x forward revenue based on its $4.4 billion run-rate target, a discount to hyperscaler cloud peers that trade at 8-12x sales, reflecting the execution risk embedded in its transition from Bitcoin mining to AI infrastructure.
