In a year marked by significant achievements for Bitcoin mining firms, Singapore-based BitFuFu and Australian miner IREN have recorded new performance highs in June. These notable developments stand out amid the mixed signals currently observed in the mining sector.
IREN, which trades on the Nasdaq stock exchange, reported a record-high monthly revenue of $68 million in June. Additionally, the company recorded a peak hardware profit of $51 million. IREN operates data centers for Bitcoin mining, AI cloud services, and other computing uses solely powered by renewable energy, as per the company’s website.
“We achieved several noteworthy milestones in the past month,” said co-founder and co-CEO Daniel Roberts. “Not only did we record another month of peak revenues, but we also executed an oversubscribed convertible note offering, hit our self-mining target of 50 EH/s, transitioned to U.S. domestic issuer status, and more than doubled our AI Cloud business with the procurement of next-generation NVIDIA Blackwell GPUs.”
BitFuFu, another Nasdaq-listed firm, disclosed an all-time high total hashrate and power capacity under management of 36.2 EH/s and 728 MW, respectively. The company also reported holding 1,792 BTC, valued at approximately $193.7 million, as of June 30. “June was the most productive month of 2025, with 445 Bitcoin mined due to the continued expansion of our mining fleet,” said BitFuFu Chairman and CEO Leo Lu.
Despite these high points for IREN and BitFuFu, Bitcoin’s monthly revenue slightly dipped between May and June. Data from The Block’s Data Dashboard showed an 8.6% decrease from May’s $1.52 billion to June’s $1.39 billion. Meanwhile, MARA, another crypto mining company, recorded a big win in May this year, increasing the second-largest publicly traded Bitcoin treasury to 49,179 BTC, worth approximately $101 million.
The Block, an independent media outlet delivering news, research, and data, reported these developments. As of November 2023, Foresight Ventures is a majority investor of The Block. However, The Block continues to operate independently to deliver objective, impactful, and timely information about the crypto industry.
