Unlike MARA, which retains most of its mined Bitcoin, Bitdeer sells its coins to fund its ambitious expansion plans.

Bitdeer’s mining growth and technology

Bitdeer, a Singapore-based technology company, has rapidly emerged as the leader in Bitcoin mining, surpassing MARA Holdings. By the end of December 2025, Bitdeer’s mining capacity reached 71 exahashes per second (EH/s), which accounts for nearly 6% of the global hash rate

The company’s success stems from its innovative SEALMINER rigs, which it has developed in-house for efficient Bitcoin mining. Bitdeer’s ability to produce such high hash rates is coupled with an impressive year-on-year growth of 229%.

In addition to its mining rigs, Bitdeer’s strategy includes hosting services and cloud services that support third-party mining operations. This hybrid model has helped the company extend its market share while bolstering its mining output.

Strategic diversification and AI investments

Beyond Bitcoin mining, Bitdeer is actively investing in artificial intelligence (AI) and high-performance computing. The company has expanded its footprint across multiple countries, including Canada, Ethiopia, Norway, and the United States

This diversification shows Bitdeer’s aim to establish a presence in both the Bitcoin and AI industries. These efforts align with its broader vision of becoming a key player in AI and advanced computing infrastructure.

Bitdeer’s growth is a reflection of a larger trend in the mining sector where companies are diversifying their focus to ensure long-term sustainability. The company is betting on the intersection of Bitcoin mining and AI to stay competitive in the evolving tech landscape.

MARA holdings: A contrasting approach

MARA Holdings, on the other hand, has long been a dominant force in Bitcoin mining. It primarily relies on mining hardware from Bitmain and operates extensive data centers to support its operations. While Bitdeer focuses on self-made technology, MARA uses third-party hardware to mine Bitcoin

Unlike Bitdeer, which sells its mined Bitcoin to fund expansion, MARA retains most of its mined assets. This strategy has helped the company build one of the largest Bitcoin treasuries among publicly traded miners, with over 55,000 BTC.

However, like Bitdeer, MARA is also venturing into AI technologies. The company, while diversifying its operations, continues to focus on holding its mined Bitcoin, maintaining its position as the second-largest BTC treasury holder among public companies.

Bitdeer’s rise to the top of the Bitcoin mining world underscores a major shift in the industry. The company’s innovative approach to mining, combined with strategic investments in AI and high-performance computing, has enabled it to surpass MARA Holdings by hashrate

This shift marks a new era for Bitcoin mining companies, emphasizing technological innovation and diversification to stay ahead in an ever-changing market.
