Bitcoin production surges in May

Mara Holdings, one of the largest publicly traded Bitcoin mining companies in the U.S., significantly increased BTC production in May 2025 amid rising hashrate and network difficulty.

The company mined 950 BTC during the month, marking a 35% month-over-month increase, according to its June 3 production report.

Mara also achieved a record of 282 blocks mined, reflecting a 38% increase compared to April.

Bitcoin holdings exceed 49,000 BTC

Following its May results, Mara’s Bitcoin reserves rose to 49,179 BTC, valued at approximately $5.2 billion at current prices.

Chief Financial Officer Salman Khan highlighted that no Bitcoin was sold during May:
“One of our biggest advantages is operating our own mining pool.”

The advantage of a proprietary pool

Chairman and CEO Fred Thiel emphasized Mara’s fully integrated tech stack as a key industry differentiator.

“Operating our own pool means no external fees and full retention of block rewards,” Thiel stated.

He added that May’s production benefited from block reward luck, outperforming the network average by more than 10%.

Hashrate and difficulty reach record levels

Despite higher production, Bitcoin mining continues to get harder. On May 31, Bitcoin’s hashrate reached a new all-time high of 942 EH/s, according to Blockchain.com.

Additionally, on May 30, Bitcoin mining difficulty rose to over 126 trillion following another upward adjustment.
