CleanSpark recorded an over 9% increase in Bitcoin Mining output during May, elevating its total holdings to 12,502 BTC—twice the volume it possessed in the corresponding period a year ago.
As outlined in its monthly disclosure, a 9.4% increase in Bitcoin (BTC) production was reported by the company for May, with 694 coins generated versus 633 in April. Additionally, CleanSpark boosted its hash rate to 45.6 exahashes per second from April’s 42.4, while its contracted power capacity grew to 987 megawatts.
“May marked a solid month of operational performance for CleanSpark,” stated Zach Bradford, who serves as the company’s CEO and president. “We boosted our end-of-month hashrate to 45.6 EH/s, reflecting a 7.5% sequential rise, while also enhancing overall fleet efficiency.”
In May, the firm’s Bitcoin holdings climbed to 12,502 BTC, reflecting a 103% increase over the previous year. This growth, attributed solely to CleanSpark’s mining activities, has reportedly occurred without any new equity issuance since November 2024. As the sixth-largest publicly traded holder of Bitcoin, the company views this milestone as a strong endorsement of its infrastructure-led approach. “It’s a powerful validation of our infrastructure-first strategy,” remarked CEO Zach Bradford.
