Bitcoin (<a target="_blank" rel="noopener noreferrer nofollow" href="https://coinmarketcap.com/currencies/bitcoin/">BTC</a>) miner CleanSpark sold 702 BTC in September, more than the 529 it mined, and said it will stop publishing monthly operational updates as it moves to quarterly reporting.
The shift comes as CleanSpark steers capital toward data centers. Its subsidiary closed $2.276 billion of senior secured notes to fund a build-out tied to a lease expected to generate about $6.6 billion in contracted revenue over its initial term, the company said.
CleanSpark's holdings fell to 13,530 BTC at the end of September from 13,703 at the end of August, according to its <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.prnewswire.com/news-releases/cleanspark-releases-september-2026-operational-update-302903249.html">September update</a>.<tweet-embed url="https://x.com/CleanSpark_Inc/status/2108538414127513645"></tweet-embed>
Of the 702 BTC sold, 700 were delivered through call <a target="_blank" rel="noopener noreferrer nofollow" href="https://coinmarketcap.com/academy/glossary/option">option</a> exercises and two were sold at spot. The average price was $72,928, a figure that includes net option premiums.
Of its 13,530 BTC, 3,475 were posted as <a target="_blank" rel="noopener noreferrer nofollow" href="https://coinmarketcap.com/academy/glossary/collateral">collateral</a> or receivable, all tied to derivative transactions, the company said.
"With non-dilutive bond financing now in place, our Sandersville project is fully funded through completion," CEO Matt Schultz said.
