Singapore-based cloud Bitcoin mining firm BitFuFu has recorded its most productive month of the year, driven by the expansion of its mining fleet.
In a statement released Monday, BitFuFu announced it mined 445 Bitcoin in June—an 11.3% increase from the previous month. Of the total, 387 BTC came from cloud mining operations, while 58 BTC were generated through self-mining.
“June was our most productive month of 2025,” said Leo Lu, Chairman and CEO of BitFuFu, crediting the milestone to the “continued expansion of our mining fleet.”
Earlier this year, the company entered a two-year agreement with mining hardware giant Bitmain to purchase up to 80,000 Bitcoin mining machines.
BitFuFu currently holds 1,792 BTC—valued at over $193 million. By comparison, top mining firm MARA Holdings holds 50,000 BTC, followed by Riot Platforms with 19,225 BTC, and CleanSpark with 12,608 BTC.
BitFuFu Sees Surge in Hashrate
BitFuFu’s hashrate rose 6.2% month-over-month in June, reaching 36.2 exahashes per second (EH/s)—a key measure of computational power. Of that total, 32.4 EH/s came from third-party suppliers and hosting clients.
The company’s power capacity also saw a notable increase, climbing 11.8% from the previous month to 728 megawatts, with operations spanning five continents.
“Achieving record highs of 36.2 EH/s in hashrate and 728 MW in power capacity, we’re proud of the strong operational momentum we’ve built in the first half of the year,” said CEO Leo Lu. “It’s a testament to our disciplined execution and ability to scale effectively.”
BitFuFu shares see slight bump
Shares of BitFuFu (FUFU) closed Monday’s trading session up 1.16% at $3.48, marking an 8.82% gain over the past five days.
Earlier this year in January, the stock jumped 13% to $5.60 following news of a two-year supply agreement with mining hardware giant Bitmain.
Several major Bitcoin mining stocks saw sharp gains ahead of the early market close last Thursday, which preceded the U.S. Independence Day holiday weekend.
Shares of Riot Platforms (RIOT), Hive Digital (HIVE), Hut 8 (HUT8), MARA Holdings (MARA), and Bitfarms (BITF) surged between 13% and 28% over the four trading sessions leading up to the break.
Bitcoin Miners Post Mixed Results in June
Several Bitcoin mining companies reported a drop in production during June, largely due to power curtailments in Texas. Riot Platforms, for instance, saw a 12% decrease in output compared to May.
In contrast, Australian-based miner IREN had a record-breaking month, generating 68 million Australian dollars ($44 million) in revenue. The company credited rising Bitcoin prices for offsetting the impact of a shorter month on production. IREN mined 620 BTC in June, slightly down from 627 in May, while its average hashrate rose to 41.1 EH/s from 38.4 EH/s the previous month.
CleanSpark also posted strong growth, with its operational hashrate soaring to 50 EH/s in June—a 145.1% increase from 20.4 EH/s a year earlier. The company mined 685 Bitcoin last month, up significantly from 445 BTC in June 2024.
