Record-Breaking Month for MARA
May 2025 marked a historic milestone for MARA, with the company securing 282 Bitcoin blocks—a 38% increase month-over-month and the highest monthly total to date. This surge in block wins directly contributed to 950 BTC produced, up 35% from April, making it the most productive month since the Bitcoin halving event in April 2024.
These figures underscore MARA’s growing operational strength and technological edge in an increasingly competitive mining landscape. The average daily Bitcoin production reached 30.7 BTC, reflecting a 31% improvement over the prior month.
Strategic Advantage: Fully Integrated Tech Stack
A key driver behind MARA’s success is its fully integrated digital infrastructure, which combines energy sourcing, high-performance computing, and proprietary mining pool technology.
Fred Thiel, Chairman and CEO of MARA, emphasized the significance of this vertical integration:
“Our fully integrated tech stack is a key differentiator. MARA Pool is the only self-owned and operated mining pool among public miners, offering greater control and efficiency. Operating our own pool means no third-party fees and full retention of block rewards.”
This self-sufficiency not only reduces operational costs but also enhances profitability by eliminating intermediaries. Since its launch, MARA Pool has outperformed the Bitcoin network average in block reward luck by over 10%, further boosting yield efficiency.
Operational Highlights – May 2025
- Blocks Won: 282 (+38% MoM)
- BTC Produced: 950 (+35% MoM)
- Average Daily BTC Production: 30.7 BTC (+31% MoM)
- Energized Hashrate: 58.3 EH/s (+2.0% MoM)
- Share of Available Miner Rewards: 6.5%
- Transaction Fees as % of Total Rewards: 1.5%
The steady increase in energized hash rate—now at 58.3 exahashes per second (EH/s)—demonstrates MARA’s ongoing deployment of advanced mining hardware and infrastructure optimization. Even with minimal hash rate growth, the significant jump in block production suggests improved network efficiency and superior pool performance.
Growing Bitcoin Reserves
As of May 31, 2025, MARA held a total of 49,179 BTC, including loaned and collateralized Bitcoin. Notably, the company did not sell any Bitcoin during the month, reinforcing its long-term holding strategy and confidence in the asset’s future value.
This accumulation trend aligns with MARA’s broader vision of becoming a cornerstone player in the digital asset ecosystem—not just as a miner, but as a steward of decentralized network security and sustainable energy innovation.

Sustainable Energy & Digital Infrastructure
MARA leverages high-intensity compute workloads like Bitcoin mining to monetize excess and underutilized energy, particularly clean or stranded power sources. By converting this otherwise wasted energy into economic value, the company supports both grid stability and environmental sustainability.
This model positions MARA at the intersection of energy innovation and blockchain security, creating a resilient business framework capable of withstanding macroeconomic fluctuations.

Frequently Asked Questions (FAQ)
Q: What is MARA Pool, and why is it important?
A: MARA Pool is MARA’s proprietary, self-operated Bitcoin mining pool. Unlike most public miners that rely on third-party pools, MARA maintains full control over its mining operations, eliminating external fees and maximizing reward retention. This vertical integration enhances efficiency and profitability.
Q: How does block reward luck affect mining output?
A: Block reward luck refers to the statistical variance in how frequently a miner finds blocks compared to the expected average. MARA Pool has consistently outperformed the network average by over 10%, meaning it earns more blocks than probability would suggest—directly increasing BTC production without additional hash power.
Q: Why didn’t MARA sell any Bitcoin in May?
A: The decision reflects MARA’s long-term confidence in Bitcoin’s value appreciation and its strategy to grow its digital asset treasury. Holding rather than selling strengthens balance sheet resilience and signals commitment to stakeholders.
Q: What does “energized hash rate” mean?
A: Energized hash rate refers to the total computational power actively secured to the Bitcoin network by MARA’s mining rigs. At 58.3 EH/s, it represents one of the largest operational capacities among publicly traded miners.
Q: How does MARA use stranded energy?
A: MARA deploys mining infrastructure near sources of excess or underused energy—such as remote renewable plants or flare gas sites—to convert wasted power into Bitcoin. This not only improves energy economics but also reduces environmental waste.
Q: Is MARA exposed to price volatility risks?
A: Like all miners, MARA faces Bitcoin price fluctuations. However, its vertical integration, low-cost energy access, and conservative financial approach help mitigate risks. The company focuses on operational efficiency rather than short-term market timing.
