Canaan (NASDAQ:CAN) closed 2025 with a significant expansion of its self-mining operations, reporting on Wednesday that its deployed hashrate surged 82% year-over-year to 9.91 exahashes per second (EH/s).
The growth rate for the Singapore-based mining hardware pioneer significantly outpaced the broader Bitcoin network’s hashrate increase of approximately 34% over the same period.
The company’s December 2025 update revealed an operating hashrate of 7.65 EH/s, a 61% annual increase, resulting in the production of 86 BTC for the month.
Despite fluctuations in mining difficulty, Canaan continued to strengthen its "HODL" strategy, ending the year with a record cryptocurrency treasury of 1,750 BTC and 3,951 ETH.
Canaan’s operational results reflect a transition toward more efficient, next-generation hardware.
The company reported an average global miner efficiency of 24.3 J/TH, aided by the deployment of its latest Avalon A16 and A15 series machines.
This efficiency, combined with an average all-in power cost of $0.043/kWh, has allowed the firm to maintain profitability even as global "hashprice"—the revenue earned per unit of computing power—faced downward pressure.
