Singapore-based cloud Bitcoin miner BitFuFu has logged its most significant production month for the year, attributed to an expanded mining fleet.
BitFuFu said on Monday it mined 445 Bitcoin in June, representing an 11.3% month-over-month increase for the firm. It said that 387 Bitcoin (BTC) came from cloud mining and 58 from self-mining.
Leo Lu, chairman and CEO of BitFuFu, said June has been its “most productive month of 2025,” which he attributes to the “continued expansion of our mining fleet.”
In January, BitFuFu said it had signed a two-year agreement with mining hardware giant Bitmain to purchase up to 80,000 Bitcoin miners.
BitFuFu currently holds 1,792 Bitcoin, currently worth over $193 million. In comparison, the top mining firm, MARA Holdings, holds 50,000 Bitcoin, while No. 2 Riot Platforms has 19,225, and the third-biggest mining firm, CleanSpark, holds 12,608.
BitFuFu hashrate spikes
BitFuFu’s hashrate also increased 6.2% month-over-month to 36.2 exa hash per second (EH/s), a measurement of computational power, with 32.4 EH/s coming from third-party suppliers and hosting customers.
The mining firms’ power capacity also increased by 11.8% month-over-month to hit 728 megawatts across five continents.
“Reaching record levels of 36.2 EH/s in hashrate and 728 MW in power capacity, we’re proud of the strong operational momentum in the first half of the year, which reflects our ability to scale effectively and execute with discipline,” Lu said.
BitFuFu shares see slight bump
Shares in BitFuFu (FUFU) closed the Monday trading session up 1.16% at $3.48. Its stock price has risen 8.82% in the last five days.
In January, BitFuFu shares surged 13% to $5.60 due to the two-year agreement with mining hardware giant Bitmain.
Meanwhile, other miners’ stocks surged in the lead-up to US markets closing early last Thursday ahead of the Independence Day holiday weekend.
Shares of Riot Platforms (RIOT), Hive Digital (HIVE), Hut 8 (HUT8), MARA Holdings (MARA), and Bitfarms (BITF) spiked between 13% and 28% in the last four sessions leading up to the break.
Bitcoin miners have mixed bag in June
Several Bitcoin mining firms reported lowered Bitcoin production in June, mainly due to power curtailment in Texas, with Riot Platforms reporting a 12% decline in May.
Australian-based Bitcoin miner IREN had a record-breaking month, with revenues reaching 68 million Australian dollars ($44 million), driven by higher Bitcoin prices that offset the decline in production caused by a shorter month in June, the firm said on Monday.

IREN mined 620 Bitcoin compared to 627 in May, and its hashrate averaged 41.1 EH/s compared to last month’s 38.4 EH/s.
Meanwhile, CleanSpark posted an operational hashrate of 50 EH/s in June from 20.4 EH/s a year earlier, representing a 145.1% jump in mining capacity. It mined 685 Bitcoin, up from 445 in June 2024.
