Bitdeer Technologies Group Update
In a substantial update, Bitdeer Technologies Group has announced that its total hashrate management reached 71 exahashes per second (EH/s) by the close of December 2025, positioning it potentially above MARA Holdings Inc. in terms of overall Bitcoin mining capacity. This total comprises 55.2 EH/s allocated to its own mining efforts as well as additional capacity for third-party hardware hosting. In contrast, MARA has reported a total of 61.7 EH/s on its official platform.
Market Position and Comparisons
MARA has been recognized as the leading publicly traded Bitcoin miner with its own generation of hashrate since mid-2023, having surged from below 20 EH/s to exceeding 60 EH/s by September 2025. However, the metrics used to assess Bitdeer’s “total hashrate under management” are not directly comparable to MARA’s “energized hashrate”, leading to some ambiguity in evaluating their relative standings.
Bitdeer’s Mining Capacity
According to reports, Bitdeer’s self-mining capacity stands at 55.2 EH/s, supported by over 1,100 mining chips, with 538 of those chips operating under subscription agreements. Matt Sigel, Head of Research at VanEck, noted on social media that Bitdeer’s reported capacity represents roughly 6% of the global hashrate, marking an 18% increase from the previous month and a remarkable 229% year-over-year expansion.
Transition to AI Ventures
As the competition intensifies, Bitdeer has focused on selling the entirety of its mined output, enabling a transition to artificial intelligence ventures. In December 2025, Bitdeer successfully mined 636 bitcoins, a significant rise from the 145 bitcoins mined in December 2024.
Energy Efficiency Comparison
The efficiency of Bitdeer’s SEAL04-1 chip, which operates with an energy consumption of about 6-7 joules per terahash, shows a stark difference compared to MARA’s stated fleet energy efficiency of 19 joules per terahash. However, it’s vital to note that these figures might not be directly comparable in terms of operational efficiency.
Expansion and Bitcoin Holdings
Additionally, Bitdeer is amplifying its operations by establishing AI and high-performance computing facilities across eight locations in Canada, Ethiopia, Norway, and several states in the U.S., including Ohio, Tennessee, and Washington. Meanwhile, MARA boasts 18 data centers primarily utilizing Bitmain’s Antminer ASIC chips and has adopted a strategy of retaining its mined bitcoins, now holding more than 55,000 bitcoins—making it the second-largest bitcoin treasury among publicly traded firms, with Bitdeer holding 2,017 bitcoins, as per recent disclosures.
Impact of AI on Bitcoin Mining
The rise of artificial intelligence is significantly affecting the economics of Bitcoin mining, driving companies to enhance their high-performance computing capabilities while ensuring access to affordable energy resources.
