Bitdeer Surpasses Marathon (MARA) in Self‑Mining Hash Rate as SEALMINER Fleet Scales, Says JPMorgan

Bitdeer just moved to the front of the public‑miner pack in self‑mining capacity, a shift JPMorgan’s analyst team led by Reginald Smith flagged after the company’s latest deployment sprint. The Singapore‑based operator is now running 63.2 EH/s for its own account, nudging past Marathon Digital (MARA) at 60.4 EH/s. The delta was created in a single month: Bitdeer added 8 EH/s, powered by its proprietary SEALMINER rigs.

The interesting thread here isn’t the scoreboard—it’s what’s driving the lead. Bitdeer’s vertical move into custom silicon is beginning to bend its cost curve and refresh cadence, two variables that dictate miner survivability when difficulty ratchets higher or transaction fees normalize. By controlling the ASIC design and rollout tempo, Bitdeer can target energy efficiency, airflow, and firmware behaviors that off‑the‑shelf buyers can’t fully optimize. That typically unlocks three advantages: lower joules per terahash, tighter integration with facility design, and more negotiation leverage across the supply chain. In practice, that’s how you scale 8 EH/s in weeks rather than quarters.

Results are showing up in output and treasury strategy. In January, Bitdeer mined 668 BTC—up roughly 430% year‑over‑year. At the same time, it accelerated selling. The company ended the month with 1,530 BTC, down from 2,017 in December; at roughly $68,000 per coin, that stash was worth about $104 million. Some will read that as a signal of balance‑sheet pragmatism—recycling coins into capex to keep SEALMINER rollouts on schedule and to secure additional power and real estate—rather than a directional bet on price.

Bitdeer’s model remains mixed. While it is leaning into self‑mining, it continues to host third‑party fleets and sell subscription plans tied to mining income. Management recently cited 78.1 EH/s in total hash rate under management, with 13.0 EH/s for hosted clients. That blend helps smooth revenue and keeps utilization high as new silicon lands. The firm is also exploring U.S. data‑center leases aimed at bringing AI cloud services online this year. Importantly, leadership says SEALMINER deployments will continue alongside any AI initiatives, signaling that compute monetization will be multi‑tenant, not a pivot away from Bitcoin.

Marathon, by contrast, has recast itself as a broader digital‑infrastructure company focused on running AI workloads for customers. Historically dependent on Bitmain and other OEM gear, it stopped reporting company‑wide BTC production. And given the scale of its Middle East joint ventures, Marathon may still be the overall leader when you include non‑self‑mining arrangements as of December. The nuance matters: JPMorgan’s call is about self‑mining hash rate, not total operational influence.

Investor psychology will gravitate to the cleaner narrative. Purpose‑built silicon and rapid deployment cycles tend to command a premium when the market is rewarding operational control. AI adjacency can also earn a premium, but only if the economics of power, cooling, and tenancy are at least as compelling as Bitcoin mining on a per‑megawatt basis. On the ground, both strategies collide at the same chokepoints: power contracts, thermal design, and supply chain reliability. Proprietary ASICs that cut energy per hash can modestly reduce the carbon intensity of self‑mining, but expanded fleets still raise siting and grid‑impact questions—especially if AI and mining end up competing for the same electrons.

What to watch next: - SEALMINER rollout cadence and realized efficiency metrics (J/TH) versus incumbents - Bitdeer’s capex funding mix and whether BTC sales remain elevated - Progress on U.S. AI leasing and its impact on power allocation - Marathon’s AI workload ramp and any updates on JV‑driven capacity

Bitdeer’s new lead is less about a headline number and more about a playbook: own the stack, compress deployment timelines, and monetize compute across Bitcoin and AI without diluting focus. If that discipline holds, the hash rate gap often widens on its own.
