Insights

IREN reports record $86M revenue with significant AI cloud expansion, showing strong dual Bitcoin/AI infrastructure strategy execution.

IREN's July performance demonstrates the company is successfully executing its dual-purpose infrastructure strategy across both Bitcoin mining and AI cloud services. The record $86M monthly revenue and $66M hardware profit highlight the effectiveness of their business model in capturing value from both sectors.

Their AI cloud business is particularly noteworthy - despite contributing only $2.3M in monthly revenue compared to Bitcoin mining's $83.6M, it achieves an impressive 98% hardware profit margin versus Bitcoin mining's 76%. This exceptional margin profile validates their strategic pivot into AI computing.

The procurement of 2,400 NVIDIA Blackwell GPUs (B200/B300) represents a significant expansion of high-value compute capacity. With the initial B200 shipment already fully contracted, IREN is demonstrating strong market demand for its AI infrastructure. The $28M annualized run-rate revenue from just their Hopper GPUs provides a solid foundation while they scale the Blackwell deployment.

IREN's infrastructure development shows sophisticated planning for AI-specific requirements. The completion of the Mackenzie fiber upgrade creating redundant, physically diverse fiber paths is critical for AI workloads that demand both high bandwidth and reliability. The 50MW Horizon 1 liquid-cooled data center at Childress represents purpose-built infrastructure for intensive AI computing, showing foresight in designing for the thermal challenges of GPU clusters.

IREN's ability to run both ASICs and GPUs side-by-side at Prince George showcases their adaptable infrastructure approach, allowing them to allocate resources between cryptocurrency mining and AI computing based on market conditions and profitability. This flexibility gives them a competitive advantage over single-purpose operators in either space.

IREN's July performance showcases extraordinary mining economics in the current market environment. The 45.4 EH/s operating hashrate produced 728 BTC at a net electricity cost of just $27,976 per Bitcoin versus revenue of $114,891 per Bitcoin. This 76% hardware profit margin demonstrates exceptional operational efficiency.

The company's Bitcoin mining revenue increased by 27.6% month-over-month (from $65.5M to $83.6M), driven by both higher Bitcoin prices and increased hashrate. This combination of scale and market timing is delivering substantial financial benefits.

IREN's power strategy remains a key differentiator. Despite facing higher electricity costs at Childress (3.6¢/³ in July), their best-in-class efficiency of 15 J/TH maintains strong margins. The company is effectively monetizing its power flexibility through demand response programs, generating $1.3M in additional revenue that partially offsets their $21.6M in electricity charges.

The projected $830M illustrative annualized hardware profit at 50 EH/s (just 4.6 EH/s above current levels) demonstrates the significant near-term earnings potential. With 650MW of operational data centers at Childress and substantial additional capacity under development at Sweetwater, IREN has clear pathways for continued hashrate growth.

While the Bitcoin mining business currently dominates revenue, the company's diversification into AI cloud services creates a compelling hybrid business model. This approach provides exposure to both cryptocurrency economics and the high-growth AI infrastructure market, potentially offering shareholders more balanced risk exposure than pure-play Bitcoin miners.
