IREN Maintains High Hasrate Uptime Amid Increasing Mining Difficulty
IREN’s average hashrate during July was recorded at 45.4 EH/s, indicating sustained productivity from the majority of its mining rigs throughout the period.
This is notable given the recent rise in Bitcoin mining difficulty, which has increased energy consumption requirements and operational costs for miners. IREN’s ability to maintain uptime suggests efficient management of hardware and energy resources, despite the pressure on profit margins faced by the sector.
MARA Holdings reported a decrease in mining output for July compared to June but followed a strong second quarter, with revenue rising 64% year-on-year to $238 million. MARA holds the second-largest Bitcoin treasury, totaling 50,000 BTC, behind only Michael Saylor’s firm.
IREN Expands Revenue Streams with AI Cloud Business
In addition to Bitcoin mining, IREN generated $2.3 million of its July revenue from its growing artificial intelligence (AI) cloud business. The company has acquired 2,400 Nvidia Blackwell GPUs for AI workloads and received an initial delivery of 256 units.
Co-founder and co-CEO Daniel Roberts noted increasing market interest in these GPUs, highlighting the company’s efforts to diversify beyond cryptocurrency mining.
IREN’s share price closed Wednesday up 11.4% at $18.32, outperforming most peers who saw gains between 1% and 5%. This increase boosted IREN’s market capitalization to $4.11 billion, placing it second among publicly traded Bitcoin miners behind MARA.
At the time of press, Bitcoin (BTC) is trading at $114,423.00 USD, reflecting a 0.41% increase over the past 24 hours. The cryptocurrency reached a high of $115,678.00 and a low of $113,775.00 during this period.
