CleanSpark sold 553 BTC from its February production for roughly $36.6 million while producing 568 BTC during the month, the miner said in its latest operational update. The company finished February with a treasury of 13,363 BTC and closed on a second Texas campus that adds 300 megawatts of ERCOT-approved power capacity.
At month-end CleanSpark’s deployed fleet totaled 235,588 mining machines, delivering a peak hashrate of 50 EH/s and an average hashrate of 43.2 EH/s. Across its power portfolio the company has 1.8 gigawatts under contract, with 808 megawatts currently in use. CleanSpark reported 1,141 BTC produced year-to-date as of Feb. 28, and said 1,086 BTC of its holdings are posted as collateral or receivable in connection with derivatives transactions.
The firm is also preparing portions of its infrastructure to support artificial intelligence and high-performance computing workloads, reflecting a broader push by miners to monetize power-dense data center capacity beyond cryptocurrency mining. At the time of the update CleanSpark’s stock was down about 7.5% on the day, according to Yahoo Finance; the sector-tracking CoinShares Bitcoin Mining ETF (WGMI) was down about 6.4%.
Broader miner selling in 2026
CleanSpark’s sales are part of a larger trend among publicly traded miners liquidating BTC to fund infrastructure expansion and AI-focused projects. Examples cited in the sector include:
– Riot Platforms sold 1,818 BTC in December for about $161.6 million as it shifts toward monetizing power and data center assets. Riot reported holding 18,005 BTC as of Dec. 31, down from 19,368 a month earlier after producing 460 BTC in December.
– Bitdeer said in February that it sold its entire corporate Bitcoin treasury: 189.8 BTC produced during the period plus an additional 943.1 BTC from reserves.
– Core Scientific reported selling roughly 1,900 BTC for about $175 million in January, cutting holdings to fewer than 1,000 BTC, and later secured a $500 million credit facility from Morgan Stanley to fund high-density computing infrastructure for AI and HPC workloads.
There were also market rumors about Marathon Digital Holdings (MARA), the second-largest corporate Bitcoin treasury holder with 53,822 BTC, potentially selling reserves. MARA’s vice president of investor relations publicly denied any change to the company’s core treasury strategy.
