The Nasdaq-listed Bitcoin miner increased its treasury by 454 BTC from May, implying sales of about 160 BTC as it kept most of June output while expanding self-funded operations.
CleanSpark mined 614 BTC in June 2026 and ended the month holding 13,924 BTC, up from 13,470 BTC at the end of May. The change implies the Nasdaq-listed Bitcoin miner sold about 160 BTC during June and retained roughly 74% of its monthly production while using the rest to support operations. CleanSpark said it is operating at about 50 EH/s of hashrate with peak fleet efficiency of 16.07 J/TH, and that its contracted power capacity now exceeds 1.8 GW. The company also said it has not issued new equity since late 2024, positioning its Bitcoin accumulation strategy as funded through operational cash flows and existing resources rather than shareholder dilution.
