Marathon Digital achieved approximately 30 exahashes per second of energized hashrate in mid-2024, representing over 30,000 operational mining devices and confirming the company's status as a leading North American mining operator.
Marathon Digital Holdings installed 30.6 exahashes of mining capacity by May 31, 2024, reaching a critical scale milestone as the company races to double its operating hashrate before year-end. The achievement puts Marathon among the world's largest bitcoin miners by hashpower.
The Texas-based miner had some 246,000 bitcoin-mining devices deployed across its facilities as of the end of May, though only 237,000 were fully energized—capable of generating 29.3 exahash per second in actual operation. The gap between installed and operational hashrate reflects a challenge all large-scale miners face: power delivery and cooling constraints at individual mining sites can't always accommodate every machine at once.
Marathon began 2024 with roughly 24.7 exahashes energized and accelerated equipment purchases through the spring. In May alone, the company added about 5,000 new miners to its fleet. Each unit represents roughly 0.14 exahashes of theoretical capacity, though Marathon's facilities have been running somewhere north of 25 exahashes average—about 85 percent utilization. CEO Fred Thiel said in the May update: "With these advancements and the expansion of our fleet, we remain on track to reach our target of 50 EH/s by the end of this year."
That 50 exahash target sounds aggressive, but Marathon's April announcement signaled the company's confidence. It raised its year-end hashrate forecast from 35-37 exahashes to 50 after receiving new equipment shipments and completing additional facility optimizations. The machines Marathon has ordered for 2024 shipment would theoretically support that output, assuming power procurement keeps pace.
The growth strategy depends on two factors: steady hardware supply and available electrical capacity. Marathon controls both to some degree. The company sources machines from manufacturers and has signed power agreements with operators across Texas and Montana. But both supply chains face demand pressure as other North American miners expand simultaneously.
Mining economics at scale also shifted. Bitcoin price ranged between $61,000 and $70,000 in May, supporting positive margins for operators running new-generation hardware like Marathon's. Older equipment becomes harder to justify energizing when electricity costs exceed revenue per day. That keeps utilization rates below theoretical maximums, though Marathon's average 85 percent utilization still represents serious productive capacity.
