Data center lenders are starting to pick and choose clients. The Miner Weekly newsletter report from BlocksBridge Consulting on October 8 revealed that lenders are becoming increasingly selective in deploying capital as Bitcoin miners scramble for artificial intelligence (AI) and high-performance computing (HPC) contracts.
IREN felt this divergence firsthand in the debt market. The mining company announced a $3.65 billion graphics processing unit (GPU) financing package on June 1 for a Microsoft cloud contract at a blended interest rate of 6%. However, in its August financial report, IREN disclosed a separate $2.4 billion loan facility carrying a fixed 9% interest rate for an air-cooled expansion in Mackenzie - a full three-percentage-point difference for the exact same borrower.
Why Two IREN Projects Faced Different Interest Rates
BlocksBridge cautioned against comparing the two IREN financing packages directly, noting they fund projects with distinct risk profiles. The 6% package is supported by the certainty of a long-term contract with Microsoft. Roughly 85% of IREN’s revised target is already contracted, with customer prepayments covering about 45% of the associated GPU capital expenditure.
IREN’s cash position remains strong. As of June 30, 2026, the company held roughly $7.6 billion in cash and cash equivalents, including restricted cash. Prior to announcing the Mackenzie deal, IREN also issued $3 billion in senior notes in May 2026 with a 1% coupon maturing in 2033 under Rule 144A offerings for qualified institutional buyers.
Google Warrant Structure and Cipher Credit Facility
Strict financing patterns are also evident across other projects. At Cipher Digital’s Barber Lake facility, Google provided backing through a $1.4 billion backstop guarantee on Fluidstack’s lease obligations. In exchange, Google received warrants representing roughly 5.4% of Cipher’s equity.
Cipher Digital also secured a separate $200 million credit facility at SOFR plus 1.25 to 1.75 percent maturing in March 2030. At the time of the report, this credit facility remained completely undrawn, reflecting management’s caution in taking on recurring interest expenses.
A $5 Billion CapEx Gap
The race into AI demands heavy cash outlays that remain out of step with current revenues. Data from nine publicly traded miners shows that capital expenditure in the first half of 2026 reached $5.11 billion. On the other hand, direct revenue reported from AI/HPC operations over the same period stood at just $341.2 million.
Revenue from the computing segment is indeed starting to grow: combined AI/HPC revenue in the second quarter of 2026 touched $205.8 million, up 52% from the previous quarter. However, the gap between capital outflows and incoming revenue remains wide. For miners betting on AI infrastructure, loan interest structures now dictate who can survive until those computing contracts turn profitable.
