Singapore-based Bitdeer has surpassed American miner MARA in terms of total computing power.
Singapore-based Bitdeer has become the largest Bitcoin miner, according to The Block. The publication noted that it surpassed the American company MARA in terms of computing power used to mine the leading cryptocurrency.
According to Bitdeer, at the end of 2025, the company's “total hashrate under management” was 71 EH/s (exahash per second). Of this, 55.2 EH/s was accounted for by the miner's own mining. MARA, which has been the industry leader in recent years, reports an “active hashrate” of 61.7 EH/s.
The publication notes that it is comparing Bitdeer's “total hashrate under management” with MARA's “active hashrate.” The company does not specify what share of the latter is accounted for by MARA's own capacity.
The global hashrate on January 14 is about 1020 EH/s, according to Hashrate Index. In total, Bitdeer and MARA's declared capacities account for about 13% of global mining, which is comparable to the total volume of Russian mining, estimated at 16%.
Bitdeer was founded by Bitmain co-founder Jihan Wu, who separated it from the latter in 2020. The company is increasing its mining hashrate thanks to its proprietary chips and SEALMINER ASIC miners. In December 2025, Bitdeer earned 636 bitcoins with their help, which is four times more than the 145 BTC it mined in December 2024.
Singapore-based Bitdeer is expanding its infrastructure for artificial intelligence and high-performance computing in parallel with mining. It is investing in construction projects at a minimum of eight sites in Canada, Ethiopia, and Norway, as well as in the US states of Ohio, Tennessee, and Washington.
MARA operates 18 data centers, which mainly use Bitmain's Antminer series mining equipment. MARA is also diversifying its business by moving into AI and mainly trying to store the bitcoins it mines.
MARA owns approximately 53,000 BTC, ranking second among public companies accumulating Bitcoin after Michael Saylor's Strategy, which has more than 687,000 BTC, according to BitcoinTreasuries. Bitdeer holds 1,900 BTC, ranking 35th in this rating.
