MARA Holdings’ Strategic Increase in Bitcoin Reserves

Enhanced Bitcoin Holdings at MARA Holdings

In a noteworthy development, MARA Holdings Inc., a prominent cryptocurrency mining entity based in the United States, has strategically bolstered its Bitcoin reserves. As of September, the firm reported an additional 373 BTC, raising its total Bitcoin holdings to 52,850 BTC from the previous 52,477 BTC. With this significant increase, MARA remains the second-largest publicly traded company in terms of Bitcoin reserves, following closely behind Michael Saylor’s Strategy.

An official announcement earlier today highlighted that MARA Holdings’ Bitcoin holdings are currently valued at approximately $6.4 billion, according to prevailing market prices. Intriguingly, in September alone, the firm successfully mined 736 BTC, which is valued at around $88.6 million. This achievement marks a 4.4% increase compared to the 704 BTC mined in August 2025. Notably, the Bitcoin mined by MARA Holdings in September accounts for around 5.2% of all miner rewards, encompassing transaction fees accrued over the month.

Fred Thiel, Chairman and CEO of MARA Holdings, emphasized the company’s operational resilience: “In September, we produced 218 blocks, a 5% increase over August. This demonstrates the continued strength and resilience of our operations, even as the global hashrate grew 9% month-over-month to an average of 1,031 EH/s. Our growth in production underscores our ability to execute consistently, even as mining becomes more challenging.”

Additional Firms in Bitcoin Reserve Strategies

While MARA Holdings plays a pivotal role in Bitcoin mining, it trails Strategy—recognized as the leading public company with the largest Bitcoin reserves. Recently, Strategy expanded its Bitcoin holdings by acquiring an additional $22 million worth of BTC, resulting in a formidable total of 640,031 BTC, valued at approximately $77 billion.

Joining these ranks are other notable public entities such as Twenty One with 43,514 BTC, Japan-based Metaplanet holding 30,823 BTC, and Bitcoin Standard Treasury Company with reserves of 30,021 BTC. Additionally, corporations such as Trump Media & Technology Group Corp., Galaxy Digital Holdings, Coinbase Global, Tesla, and Jack Dorsey’s Block are among the top 15 public companies with significant Bitcoin reserves.

Diversifying Corporate Treasury into Altcoins

Bitcoin continues to dominate as the most widely adopted cryptocurrency, yet altcoins like Ethereum (ETH), Solana (SOL), and Avalanche (AVAX) are gaining traction as alternative investment options. For example, VisionSys AI, a company listed on NASDAQ, recently disclosed plans to establish a treasury program based on Solana, with an estimated value of up to $2 billion. Similarly, a new Avalanche-based treasury initiative is set to acquire $1 billion worth of AVAX tokens by 2026.

On the Ethereum front, BitMine’s recent acquisition of 46,225 ETH in September has expanded its total ETH holdings to over 2.1 million ETH. As of this writing, BTC is trading at $121,791, marking a 1.7% increase in the last 24 hours.
