In a historic shift for the industrial mining sector, Bitdeer Technologies Group has officially surpassed MARA Holdings (formerly Marathon Digital) to become the world’s largest Bitcoin miner by managed hashrate. As of January 2026, Bitdeer reports a staggering 71 EH/s of total hashrate under management, eclipsing MARA’s reported energized capacity of 61.7 EH/s. This milestone highlights a major changing of the guard, driven by Bitdeer’s aggressive deployment of its proprietary SEALMINER technology and a strategic pivot toward high-performance computing (HPC).

Bitdeer vs MARA: A New King of Managed Hashrate

The race for dominance in the crypto mining rankings has long been led by MARA, but Bitdeer’s latest operational update reveals a new hierarchy. The Singapore-based tech giant reported that its total managed hashrate surged to 71 exahashes per second (EH/s) by the end of December 2025. This figure combines 55.2 EH/s of self-mining capacity with machines hosted for institutional clients.

By comparison, MARA Holdings reported an energized hashrate of approximately 61.7 EH/s for the same period. While MARA arguably retains a lead in pure self-mining capacity, Bitdeer’s massive managed fleet gives it a superior footprint in total network processing power. This Bitdeer managed hashrate dominance allows the company to exert significant influence over the global hashrate, which currently stands at roughly 6% of the entire Bitcoin network.

SEALMINER Chip: The Secret Weapon Behind the Surge

The primary engine behind Bitdeer's explosive growth is its proprietary hardware. Unlike competitors relying on third-party manufacturers, Bitdeer successfully deployed its own SEALMINER chip (specifically the SEAL04-1), which has revolutionized its fleet efficiency. The new rigs boast an efficiency rating of roughly 6–7 Joules per Terahash (J/TH), a figure that drastically undercuts the industry average.

In contrast, MARA’s fleet efficiency is reported at around 19 J/TH. This technological gap means Bitdeer can mine Bitcoin at significantly lower electricity costs, a crucial advantage as mining difficulty continues to hit all-time highs. The successful rollout of the SEALMINER A2 and upcoming A3 series has allowed Bitdeer to rapidly scale its operations while phasing out older, less efficient machines.

Stock Market Reaction: BTDR Stock News

Wall Street has reacted swiftly to the reshuffling of the leaderboard. Following the announcement, BTDR stock news highlighted a double-digit surge, with shares jumping over 15% as investors priced in the company's enhanced operational efficiency and growth prospects. Analysts have noted that Bitdeer's vertical integration—designing its own chips and building its own data centers—offers a "moat" that pure-play miners like MARA lack.

Strategic Pivot: AI Data Centers and Infrastructure

While Bitcoin mining remains its core revenue driver, Bitdeer is leveraging its massive power capacity to expand into industrial bitcoin mining's new frontier: Artificial Intelligence. The company is actively converting portions of its infrastructure in Washington, Tennessee, and Norway into AI-ready data centers.

This "dual-engine" strategy sets Bitdeer apart from MARA, which maintains a "HODL" strategy of keeping mined Bitcoin on its balance sheet. Bitdeer, conversely, has been selling its mined BTC to fund its ambitious AI expansion, including the deployment of NVIDIA GB200 systems. This capital recycling strategy allows Bitdeer to grow its AI-integrated data centers without diluting shareholders, a move that has resonated well with institutional investors seeking exposure to both crypto and AI infrastructure.

Outlook: The Largest Bitcoin Miner 2026 and Beyond

As we move deeper into 2026, the battle between Bitdeer vs MARA symbolizes a broader divergence in industry business models. MARA continues to bet on Bitcoin as a treasury reserve asset, while Bitdeer is positioning itself as a diversified high-performance computing powerhouse. With Bitdeer’s managed hashrate now topping the charts and its SEALMINER hardware setting new efficiency standards, the company has firmly established itself as the entity to beat in the evolving digital infrastructure landscape.
