Bitfufu June Bitcoin Output Slips to 125 BTC as Managed Power Capacity Declines

June production and daily pace

The company said it produced 125 BTC in June. Of that total, 70 BTC came from self-mining operations and 55 BTC from cloud mining services. Average daily production was 4.2 BTC, down from 5.7 BTC in May.

The decline came alongside a reduction in total power capacity under management. Bitfufu said that figure dropped to 273 megawatts in June from 346 megawatts a month earlier.

Hashrate mix shifts toward owned capacity

Bitfufu’s total hashrate under management stood at 15.3 exahash per second at the end of June. The majority of that capacity, 11.8 EH/s, came from third-party suppliers and hosting customers.

Although overall managed hashrate decreased, the company’s self-owned hashrate moved in the opposite direction. Bitfufu said its self-owned capacity rose 9.4% to 3.5 EH/s during the month.

That increase followed the acquisition and deployment of 1,200 S21 XP mining units in June. The company also said it had signed agreements to acquire and deploy another 2,000 S21 XP units in July, pointing to a continued buildout of its proprietary fleet.

Bitcoin holdings fall from May

As of June 30, Bitfufu held 1,671 BTC, down from 1,855 BTC at the end of May. The company attributed the decrease to the net effect of client receipts and upfront payments tied to 5.3 EH/s of future hashrate capacity.

According to the report, that future capacity is covered by a nine-month agreement set to begin in August 2026. The company did not present the lower month-end bitcoin balance as a result of weaker mining output alone, instead linking it to those customer-related transactions.

Efficiency remains broadly steady

Bitfufu reported an average fleet efficiency of 17.9 joules per terahash in June, compared with 17.8 J/TH in May. The small change suggests operational efficiency was largely stable even as production and managed power capacity moved lower over the month.

The June update shows a business with declining aggregate managed capacity and lower bitcoin output, but also rising self-owned hashrate through new machine deployment. It also points to further expansion plans in July through additional S21 XP acquisitions, while a separate nine-month capacity agreement is scheduled to start in August.
