Bitdeer overtakes MARA as largest bitcoin miner by “managed hashrate” metric

Bitdeer Technologies Group has reportedly become the largest bitcoin mining firm by "total hash rate under management," reporting 71 exahashes per second (EH/s) as of the end of December, surpassing MARA Holdings Inc.'s reported capacity of 61.7 EH/s. Bitdeer's figure includes both self-mining (55.2 EH/s) and hosted rigs, though the article notes this metric may not be directly comparable to MARA's "energized hashrate."

Bitdeer is leveraging its proprietary SEALMINER chips for growth and is aggressively funding an AI pivot by selling mined bitcoin. The company is also scaling its AI and HPC infrastructure across multiple global sites. In contrast, MARA, historically the leader by self-mining hashrate, primarily uses Bitmain chips and focuses on holding mined bitcoin, maintaining the second-largest BTC treasury among public firms.

Bitdeer was founded by Bitmain co-founder Jihan Wu and recently missed AI rollout expectations despite strong revenue growth. Both companies saw stock increases on the day of the report.
