Bitdeer Overtakes MARA as World’s Largest Bitcoin Miner by Hashrate

Bitdeer surpasses MARA Holdings to become the largest Bitcoin miner by aggregate hashrate, reaching 71 EH/s and expanding into AI and high-performance computing.

Bitdeer Technologies Group has officially surpassed MARA Holdings to become the world’s largest Bitcoin mining company by total hashrate.

Total hashrate represents the combined computing power a company uses for mining, including both company-owned and hosted mining machines.

MARA held the top position for years, but Bitdeer’s rapid expansion reflects broader structural changes reshaping the mining industry.

According to VanEck Head of Research Matt Sigel, Bitdeer recorded 71 EH/s of capacity as of the end of December, representing approximately 6% of the global Bitcoin hashrate, with 18% month-over-month growth and 229% year-over-year expansion. Sigel noted that Bitdeer, like other miners, is actively selling mined Bitcoin to fund its pivot into artificial intelligence.

Headquartered in Singapore, Bitdeer is a technology company focused on Bitcoin mining through advanced hardware capable of solving complex cryptographic equations. The company also develops high-performance computing infrastructure for artificial intelligence and other advanced computational uses.

Bitdeer has expanded its operations by deploying a growing fleet of SEALMINER rigs that it directly owns and manages across multiple regions, enabling increased Bitcoin production.

Beyond mining, Bitdeer is investing heavily in AI and high-performance computing infrastructure in Canada, Ethiopia, Norway, and the United States signaling its long-term strategy to build a dual presence in both cryptocurrency mining and artificial intelligence computing.

Bitdeer Overtakes MARA

MARA Holdings remains one of the most established Bitcoin mining firms, operating multiple large-scale data centers powered primarily by Bitmain Antminer ASIC mining equipment.

Unlike Bitdeer, MARA typically retains much of the Bitcoin it mines instead of selling it, allowing the company to accumulate one of the largest BTC treasuries among publicly traded mining companies.

MARA currently controls more than 55,000 BTC, making it the second-largest corporate Bitcoin holder, behind Strategy, which holds 687,000 BTC. In comparison, Bitdeer holds approximately 2,000 BTC.

While MARA is gradually expanding into AI operations, its core strategy remains centered on long-term Bitcoin accumulation.

Jihan Wu, the co-founder of Bitmain, founded Bitdeer in 2020 after his separation from Micree Zhan. Although its AI projects underperformed in the third quarter of 2025 despite a 173.6% year-over-year revenue increase the company continues to expand aggressively.

As reported by The Block, Bitdeer (BTDR) shares rose over 4% to $12.78, while MARA shares climbed more than 2% to $10.93.
