MARA Holdings, Inc. (NASDAQ: MARA), a leading vertically integrated digital energy and infrastructure company, has released its unaudited Bitcoin production and operational performance report for May 2025. The data reveals record-breaking achievements across key mining metrics, reinforcing MARA’s growing influence in the Bitcoin mining ecosystem.
The company reported earning a record 282 blocks in May—an impressive 38% month-over-month increase—while producing 950 BTC, up 35% from April. These figures mark the highest monthly output since the Bitcoin halving event in April 2024. MARA’s total Bitcoin holdings now stand at 49,179 BTC, all accumulated without any sales during the month.

Fred Thiel, Chairman and CEO of MARA, highlighted the significance of May’s results:
"May was a record-breaking month for MARA with 282 blocks won, a 38% increase over April and a new monthly high. Our total bitcoin holdings surpassed 49,000 BTC during May and the 950 bitcoin produced were the most since the halving event in April 2024."
Thiel attributed this success to the company’s fully integrated technology stack, which includes MARA Pool—the only self-owned and operated mining pool among publicly traded miners. This unique advantage allows MARA to retain full block rewards without paying third-party pool operator fees, significantly boosting net yield.
Additionally, favorable block reward luck contributed to the strong performance. Since its launch, MARA Pool has consistently outperformed the network average by over 10% in block reward efficiency, further enhancing production outcomes.

The Power of Vertical Integration in Bitcoin Mining
MARA’s strategic focus on becoming a fully vertically integrated digital energy company sets it apart in a competitive mining landscape. By controlling every layer—from power sourcing and facility management to proprietary mining software and pool operations—MARA achieves greater cost control, operational resilience, and adaptability.
This model enables the company to monetize underutilized or stranded energy sources, particularly clean and renewable power, converting them into valuable digital assets. As global attention shifts toward sustainable computing, MARA’s approach aligns with long-term environmental, social, and governance (ESG) goals while maximizing economic returns.

Financial and Strategic Implications
With no Bitcoin sold in May, MARA continues to adopt a HODL-first strategy, signaling strong confidence in the long-term value of digital assets. The accumulation of over 49,000 BTC positions the company as one of the largest corporate holders of Bitcoin globally.
This approach not only strengthens balance sheet resilience but also provides strategic flexibility for future financing, hedging, or expansion initiatives. In volatile market conditions, holding substantial BTC reserves can serve as both a store of value and a potential catalyst for equity appreciation.

Frequently Asked Questions (FAQ)
Q: What is MARA Pool and why is it important?
A: MARA Pool is MARA’s proprietary, self-owned mining pool. Unlike most public miners that rely on third-party pools, MARA operates its own infrastructure, eliminating external fees and allowing full retention of block rewards. This increases profitability and operational control.
Q: How does block reward luck affect mining output?
A: Block reward luck refers to the statistical variance in how frequently a miner finds valid blocks compared to expected probabilities. A positive luck streak means more blocks are found than statistically predicted. MARA Pool has outperformed the network average by over 10%, contributing significantly to its record production.
Q: Did MARA sell any Bitcoin in May 2025?
A: No. MARA did not sell any Bitcoin during May 2025. All 950 BTC produced were added to its growing reserve, bringing total holdings to 49,179 BTC.
Q: What does “vertically integrated” mean in the context of Bitcoin mining?
A: Vertical integration means MARA controls multiple stages of the mining process—energy sourcing, data center operations, hardware deployment, software development, and pool management. This reduces dependencies, lowers costs, and improves response times to market changes.
Q: How does MARA use stranded or excess energy?
A: MARA leverages underutilized or stranded energy—often renewable sources like flared gas or surplus hydro—to power its mining rigs. This transforms otherwise wasted energy into economic value while supporting cleaner energy practices.
Q: Where can I find official financial disclosures from MARA?
A: Investors can access detailed financial reports and regulatory filings through the U.S. Securities and Exchange Commission (SEC) website under Form 10-K and other periodic submissions.
Looking Ahead: Building a Sustainable Digital Energy Future
MARA remains committed to evolving beyond traditional mining into a comprehensive digital energy platform. Its focus on sustainability, innovation, and operational excellence positions it well for long-term success amid shifting macroeconomic and regulatory environments.
As Bitcoin continues to gain institutional adoption and recognition as a digital reserve asset, companies like MARA that combine technical sophistication with responsible energy use will play an increasingly vital role in shaping the future of finance and computing.
