CleanSpark parted with more bitcoin than it mined in September, and is scrapping its monthly mining reports

Another big bitcoin miner is starting to look less like a miner. CleanSpark said on Friday that it produced 529 bitcoin in September and parted with 702: two sold on the spot market and 700 delivered under call options that were exercised. The average price was $72,928 a bitcoin. Bitcoin traded at about $82,450 on Friday afternoon, according to CoinDesk.

The company's holdings fell to 13,530 bitcoin on September 30 from 13,703 a month earlier. Of those, 3,475 were posted as collateral or receivables tied to derivative trades, it said.

The bigger change is where CleanSpark is heading. A subsidiary closed $2.276 billion of 7.875% senior secured notes due 2031 to fund its Sandersville data center project, which is tied to a lease the company expects to bring in about $6.6 billion of contracted revenue over its initial term. "The demand for power and land, with the certainty to build, remains relentless," said Matt Schultz, the chief executive and chairman.

With that, the monthly production updates will end. CleanSpark said it will move to standard quarterly reporting, in line with companies in the energy and data center sectors.

The news came on the same day CoinDesk reported that MARA, another large miner, moved $81.1 million of bitcoin to Galaxy Digital as it pivots toward AI.

What to watch: CleanSpark's first quarterly report under the new schedule, and how much bitcoin it still holds by then.
