Bitdeer Technologies Group's latest disclosed data shows that, based on "managed hashrate," it has surpassed MARA Holdings Inc. to become the current largest Bitcoin mining company by hash rate. As of the end of December 2025, Bitdeer's managed hashrate is approximately 71 EH/s, including 55.2 EH/s of self-operated mining capacity, with the rest being hosted capacity; in comparison, MARA's disclosed hashrate is about 61.7 EH/s. However, it remains unclear whether the "managed hashrate" used by Bitdeer can be directly compared to MARA's disclosed "energized hashrate." (The Block)
