Bitdeer Technologies Group Emerges as Leader in Bitcoin Mining
In a significant milestone for the bitcoin mining sector, Bitdeer Technologies Group has claimed the title of the largest bitcoin mining company by total hashrate, outpacing MARA Holdings. Recent filings reveal that as of December 2025, Bitdeer boasts a total mining ability of 71 exahashes per second (EH/s), with a substantial 55.2 EH/s sourced from its own mining operations. In contrast, MARA’s reported total energized hashrate stands at 61.7 EH/s.
Performance and Technological Advancements
The shift in leadership in this competitive industry can be attributed to Bitdeer’s impressive performance in December, where the company extracted 636 BTC, a sharp increase from the 145 BTC mined during the same period the previous year. This surge is largely facilitated by Bitdeer’s innovative SEALMINER chips, which operate efficiently at approximately 6–7 joules per terahash under low-voltage conditions, vastly outperforming MARA’s reported 19 J/TH in mining efficiency.
Strategic Expansion and Investment
Bitdeer is aggressively expanding its operations, with investments in eight locations across Canada, Ethiopia, Norway, and several regions in the United States to bolster both its bitcoin and artificial intelligence infrastructures. This strategic push is being funded through the monetization of its mined bitcoin. In a contrasting strategy, MARA Holdings retains the majority of its mined bitcoins, amassing over 55,000 coins, and primarily concentrates on refining its mining capabilities using Bitmain Antminer ASICs.
Financial Performance and Industry Trends
Despite a remarkable 173.6% uptick in revenue year-over-year reported in Bitdeer’s fourth quarter of 2025, the company’s growth fell short of expectations regarding its AI investments. Analysts surveilling the industry spotlight AI-driven computational technologies and energy efficiency as pivotal elements that are currently reshaping the landscape of bitcoin mining. They note that firms are vying to enhance both their mining productivity and high-performance computing setups, indicating a transformative period for the industry.
Bitdeer’s ascendance reflects these trends, marking a new era in the competitive dynamics of global bitcoin mining.
