Overview

Bitdeer Technologies Group has surpassed MARA Holdings to become the largest bitcoin mining company 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.

Mining Performance and Efficiency

Bitdeer mined 636 BTC in December, up from 145 BTC in the same month a year earlier. The increase was supported by the company’s proprietary SEALMINER chips, which achieve approximately 6-7 joules per terahash under low-voltage conditions. MARA’s fleet reports 19 J/TH, though the comparison may not be directly equivalent.

Strategic Divergence

The Singapore-based firm continues expanding both bitcoin mining and artificial intelligence infrastructure, investing in eight sites across Canada, Ethiopia, Norway, and several U.S. states. Bitdeer has been monetizing mined bitcoin to fund its AI expansion.

In contrast, MARA maintains most of its mined BTC, holding over 55,000 coins, and focuses on consolidating mining operations primarily with chips from major manufacturers.

Financial Performance and Market Trends

Bitdeer’s Q4 2025 earnings showed a 173.6% year-over-year revenue increase, though growth fell short of investor expectations for its AI expansion. Industry analysts have identified AI-driven computing and efficient energy deployment as key factors reshaping the bitcoin mining sector, with firms competing to optimize both mining output and high-performance computing infrastructure.

Bitdeer’s growth reflects the evolving dynamics of global bitcoin mining, combining high-efficiency hardware, strategic energy access, and parallel AI investments.
