According to PR Newswire, Canaan released its Bitcoin mining and operations data for May 2026. During the month, the company produced 90 BTC through self-operated mining, while another 24 BTC came from customer payments. At the end of the period, Canaan held approximately 1,867 BTC and 3,952 ETH on its books, reaching a record high based on the figures disclosed by the company.
May BTC Output and Digital Asset Holdings
The latest disclosure focuses on three main areas: self-operated mining output, customer payments and period-end holdings. The 90 BTC produced from self-operated mining reflects the operating results of Canaan’s mining machines in May, while the additional 24 BTC from customer payments was reported separately. The company’s period-end holdings of about 1,867 BTC and 3,952 ETH formed another key part of the monthly operating update.
Canaan also disclosed that its period-end self-operated installed computing power stood at 10.05 EH/s, while operating computing power was 6.47 EH/s. These two figures describe the company’s deployed self-operated capacity and the portion running in operation at the end of the reporting period.
Efficiency Improvements and Project Updates
On mining efficiency, Canaan said the average energy efficiency of its self-operated mining machines in North America improved to 17.9 J/TH, representing an approximately 11% year-on-year optimization. Its global average energy efficiency was 23.7 J/TH, up 13.5% year on year. These numbers were disclosed alongside the company’s computing power metrics as part of its May operations data.
Canaan further reported that its joint venture project with WindHQ in Texas had been temporarily affected by wildfires and is expected to fully recover by mid-June. The company also said it is expanding a hash-rate heating project in Northern Europe and working with Tether on immersion-cooled mining machines.
