MARA posted its strongest monthly bitcoin output since the 2024 halving
MARA Holdings, Inc. (NASDAQ: MARA) said it mined 950 BTC in May 2025, worth more than $100 million at the time of writing. That was a 35% increase from April and the company’s best monthly production result since the April 2024 Bitcoin halving. For a large public miner, that matters because post-halving economics are structurally tougher, with lower block rewards forcing operators to depend more heavily on scale, uptime, energy access, and execution.
The company also said it did not sell any bitcoin in May. In practical terms, that means the full monthly production remained on the balance sheet rather than being liquidated to cover operations. For investors and industry observers, this is more than a treasury footnote. It signals confidence in liquidity management and reinforces MARA’s broader positioning as a miner that is also building a substantial long-term BTC reserve.
Chairman and CEO Fred Thiel described May as a record-breaking month. MARA won 282 blocks during the period, a 38% increase over April and a new monthly high for the company. He also noted that MARA’s total bitcoin holdings moved above 49,000 BTC during May, while the 950 BTC produced represented the most the company has mined in a single month since the halving event in April 2024.
Block wins, treasury growth, and hashrate all moved higher
The production update was not only about headline BTC output. MARA’s underlying operating metrics also improved. The company reported that energized hashrate increased from 57.3 EH/s to 58.3 EH/s, a 2% month-over-month gain. While that increase may appear modest in percentage terms, it came on top of an already large installed base and suggests continued progress in machine deployment, site execution, and power availability.
MARA’s average daily bitcoin production reached 30.7 BTC in May, up 31% from April. This is an important figure because it smooths out the monthly total into a daily operating measure, making it easier to compare performance across reporting periods. For public miners, average daily BTC production, energized hashrate, and block wins are among the clearest indicators of operational efficiency and execution quality.
At the time of writing, MARA held 49,179 BTC, worth approximately $5.23 billion. That places the company among the most significant bitcoin holders in the public mining sector. The increase reflects both fresh production and a broader strategy of retaining bitcoin rather than frequently selling into the market. In that sense, MARA is operating not just as a miner, but also as a corporate bitcoin accumulator.
MARA says its self-owned pool and integrated model create a structural edge
Fred Thiel highlighted the company’s fully integrated technology stack as a core differentiator. He specifically said that MARA Pool is the only self-owned and operated mining pool among public miners. That gives the company more control over mining operations and eliminates the need to pay fees to external pool operators. Instead of sharing part of the economics with third parties, MARA retains the full value of the block rewards it earns.
That structure matters in a mining industry where margins are constantly shaped by energy costs, machine efficiency, and fee leakage. A self-operated pool can also improve operational visibility, increase flexibility, and strengthen alignment between infrastructure decisions and mining output. Thiel added that May’s production also benefited from favorable block reward luck. Since launch, MARA Pool’s block reward luck has outperformed the network average by more than 10%, helping support what the company describes as industry-leading block production.
Management also reiterated its broader corporate direction. Thiel said MARA remains focused on transforming itself into a vertically integrated digital energy and infrastructure company. In his view, that model provides tighter operational control, better cost efficiency, and greater resilience when the broader economy shifts. In other words, MARA is trying to become more than a straightforward bitcoin miner. It is building a stack that spans energy, infrastructure, mining operations, and pool ownership in a single coordinated platform.
First-quarter 2025 results add more context to the May update
Earlier in the month, on May 8, MARA released its Q1 2025 earnings. The company reported $213.9 million in revenue, a 30% year-over-year increase. That revenue growth adds important context to the May production report, showing that the company’s expansion is not limited to bitcoin inventory growth alone. It is also generating more top-line business activity as its operating base scales.
As of March 31, MARA’s bitcoin holdings had surged from 17,320 BTC a year earlier to 47,531 BTC, a 174% year-over-year increase. At the time, those holdings were valued at approximately $3.9 billion. This sharp rise illustrates how the company has evolved beyond the profile of a conventional miner. It increasingly resembles a hybrid entity: part industrial bitcoin producer, part large-scale corporate BTC treasury holder.
During the first quarter, MARA mined 2,286 BTC and acquired an additional 340 BTC. Operationally, energized hashrate nearly doubled from 27.8 EH/s to 54.3 EH/s, while cost per petahash per day improved by 25%. When these figures are viewed alongside the strong May report, a consistent strategy becomes visible. MARA is expanding hashrate, improving efficiency, increasing BTC holdings, and relying on self-owned pool infrastructure and vertical integration to defend margins in a post-halving environment.
Overall, the May update sends several clear signals. First, MARA appears to be managing the post-halving period effectively. Second, the company continues to grow its bitcoin treasury and chose not to sell any BTC during the month. Third, the combination of pool ownership, tighter operational control, and infrastructure integration is translating into stronger production metrics. For anyone tracking public miners, bitcoin treasury strategies, or the economics of large-scale mining after the halving, MARA’s latest numbers are worth close attention.
