Catenaa, Friday, January 23, 2026-Bitdeer Technologies Group overtook MARA Holdings as the largest bitcoin mining firm by total hashrate under management, according to recent company reports.
As of December 2025, Bitdeer reported a combined self-mining and hosted capacity of 71 exahashes per second (EH/s), with 55.2 EH/s from self-mining operations.
MARA’s latest figures show 61.7 EH/s of total energized hashrate.
Bitdeer mined 636 BTC in December, up from 145 BTC in the same month a year earlier, supported by its proprietary SEALMINER chips, which achieve roughly 6–7 joules per terahash under low-voltage conditions.
MARA’s fleet reports 19 J/TH, though the comparison may not be directly equivalent.
The Singapore-based firm continues expanding both bitcoin mining and AI infrastructure, investing in eight sites across Canada, Ethiopia, Norway, and several U.S. states, while monetizing mined bitcoin to fund its AI pivot.
MARA, in contrast, maintains most of its mined BTC, holding over 55,000 coins, and focuses on consolidating mining operations primarily with Bitmain Antminer ASICs.
Bitdeer’s Q4 2025 earnings highlight a 173.6% year-over-year revenue increase, though growth fell short of investor expectations for its AI expansion.
BTDR shares rose 4% to $12.78, while MARA traded up 2% at $10.93.
Analysts note the rise of AI-driven computing and efficient energy deployment as key factors reshaping the bitcoin mining sector, with firms racing to optimize both mining output and high-performance computing infrastructure.
Bitdeer’s growth underlines the evolving dynamics of global bitcoin mining, combining high-efficiency hardware, strategic energy access, and parallel AI investments.
