Shares of IREN Limited (NASDAQ: IREN) rose 11.4% to $18.32 this week, making it the best-performing cryptocurrency mining firm. This was after the company had great results in July, when it outmined the big player MARA Holdings for the first time.

The mining firm situated in Sydney said it made 728 Bitcoin in July, which was more than MARA’s 703 BTC. However, it had a much lower average hashrate of 45.4 exahashes per second (EH/s) compared to MARA’s 58.9 EH/s. This accomplishment shows that IREN is more efficient at running its business than MARA, which had less than 75% of its mining fleet in use throughout the month.
IREN’s Record Revenue and Market Position
IREN’s outstanding mining performance led to record financial results, with the firm making $86 million in July. The outstanding figures raised IREN’s market capitalization to $4.11 billion, making it the second-largest publicly traded Bitcoin mining company by market value, behind only MARA Holdings and ahead of established companies like Riot Platforms and Core Scientific.
Daniel Roberts, co-founder and co-CEO of IREN, said, “In July, we had another month of record revenue of $86 million and record hardware profits of $66 million, thanks to strong Bitcoin mining economics and continued demand for our AI Cloud services.”
Bitcoin miners are having a hard time right now because mining is getting harder, which means they need more energy and their profit margins are getting tighter. IREN’s ability to keep such high fleet utilization rates shows that the organization is operationally excellent and its infrastructure is reliable.
Beyond Mining BTC: Diversification Into Artificial Intelligence
In addition to its success with Bitcoin mining, IREN is planning for future growth by strategically branching out into AI computing services. In July, the company’s burgeoning AI cloud division brought in $2.3 million in sales, which is a growing part of its operations.
IREN has put a lot of money on this area, buying 2,400 NVIDIA Blackwell GPUs developed just for AI workloads. They have already received 256 of the units they ordered. Roberts said there was “accelerating interest” in the company’s AI capabilities, which showed how flexible IREN’s infrastructure is for taking advantage of new market opportunities.
Running Bitcoin mining rigs and AI GPUs at the same time shows IREN’s strategic vision to lessen its reliance on cryptocurrency mining alone. This will help the company make money in other ways as the AI sector continues to grow quickly.
Remarkable Turnaround Story
Culper Research, a short-selling firm, called IREN “wildly overvalued” just over a year ago. Now, the company is doing quite well. Culper didn’t like IREN’s plans for AI and said they were like “competing to win the Monaco Grand Prix but showing up in a Toyota Prius.”
After that news, the price of IREN shares dropped from $12.31 to $5.59 in April. But the company has made a remarkable turnaround since then, with shares rising an astonishing 227% in the last four months, showing that management’s strategic direction and operational changes are working.
Industry Context and Competition
Even if IREN reached a production milestone, MARA Holdings still has a lot of advantages in other areas. The corporation has the second-largest corporate Bitcoin treasury, with about 50,639 BTC worth more than $5.8 billion. MicroStrategy is the only company with more. MARA also had a good second quarter, with sales up 64% from the same time last year to $238 million.
The competitive environment in Bitcoin mining is getting tougher as the network’s total hashrate rose above 900 EH/s for the first time in July. This is a sign of more mining activity and rivalry around the world.
