CleanSpark Pledges 12% of Bitcoin Treasury as Collateral

CleanSpark disclosed that 1,719 of the 13,924 BTC it reported as of June 30 were posted as collateral or recorded as receivables tied to derivative transactions. That represents about 12% of the company’s reported Bitcoin balance and indicates those coins were committed to financing or risk-management arrangements rather than held as unrestricted reserves.

The company produced 614 BTC in June and reported several other treasury movements. CleanSpark sold 179 BTC at spot, sold 250 BTC pursuant to call exercises, acquired 25 BTC pursuant to put exercises, and received 244 BTC related to a delta-neutral basis trade.

CleanSpark holds the 11th-largest public Bitcoin treasury among operating firms. The company’s filing noted that headline balances can include coins already serving other functions such as collateral, receivables or derivative-settlement positions.

Riot Platforms reported 15,680 BTC at quarter-end in its Q1 2026 update, including 5,802 BTC classified as restricted after the company sold 3,778 BTC for $289.5 million in net proceeds. The restricted balance equaled roughly 37% of Riot’s reported holdings.

Companies classify coins as collateral, receivables, restricted or monetized. Those classifications affect how many bitcoins are available immediately to cover expenses, debt service or capital projects.

Market data provide context for why miners use coins in financing arrangements. CoinShares estimated listed miners’ weighted-average cash cost to produce one BTC rose to about $79,995 in Q4 2025. CoinShares also calculated a hashprice near $30 per PH/day that left an estimated 15% to 20% of the global fleet operating at a loss amid higher power costs. Bitcoin traded near $62,000 on July 8, about half its October 2025 all-time high.

CoinShares projected that listed miners could derive up to 70% of revenue from AI-related services by the end of 2026, compared with roughly 30% today, citing more than $70 billion of announced GPU colocation and cloud deals. Increased demand for computing capacity raises capital needs for equipment and facilities and is reflected in some miners using bitcoin inventory in financing and derivatives arrangements rather than selling immediately.

Two firms with the same headline BTC total can have different available buffers if one holds mostly unrestricted coins while the other has coins pledged, restricted, recorded as receivables, or monetized. The next round of June and second-quarter updates from public miners will show whether CleanSpark’s disclosure is an outlier or part of a broader pattern. Market participants are watching counts of unrestricted, pledged, receivable and monetized coins in addition to headline balances.
