Bitcoin Treasury Swells as CleanSpark Inc. now holds 13,703 BTC, a result of its long-term strategy to retain self-mined coins. now holds 13,703 BTC in its treasury, the result of a long-term strategy of retaining a significant portion of its self-mined coins.
The current holdings, confirmed as of August 31, 2026, and continuing into September 2026, show substantial growth from the 10,556 BTC milestone the company first announced it had surpassed back in January 2025.
The company’s approach solidifies its position as both a large-scale mining infrastructure operator and a major corporate holder of Bitcoin. This dual identity makes its financial performance and stock valuation deeply intertwined with the price of BTC itself, moving beyond the pure economics of hashrate and energy costs.
Bitcoin treasury swells with consistent growth
CleanSpark’s journey to becoming one of the largest public holders of Bitcoin has been marked by steady accumulation. While a report highlighted the company crossing the 10,500 BTC threshold, that event occurred as of January 31, 2025, with total holdings reaching 10,556 BTC. Since then, the miner has consistently added to its reserves, demonstrating a firm commitment to its holding strategy.
By May 31, 2025, its holdings had grown to 12,502 BTC, with 2,210 BTC posted as collateral. The company continued to add to its stack throughout the year, reaching 12,827 BTC by August 31, 2025, with 3,026 BTC posted as collateral, and then crossing the 13,000 BTC mark by September 30, 2025.
This disciplined approach reflects a conviction in the long-term value of the asset. This philosophy seems to echo the sentiment that some have of never been more bullish on the digital asset’s future.
Even as parts of its holdings were used as collateral for financing and derivative transactions—such as 1,647 BTC by December 31, 2025—the overall trend has remained one of growth. By May 31, 2026, the treasury contained 13,470 bitcoins, eventually leading to the current total of 13,703 BTC reported as of August 31, 2026.
Marrying mining operations with a holding strategy
The foundation of CleanSpark’s treasury growth is its operational efficiency as a miner. The company’s unaudited update for January 2025 provides a clear snapshot of its strategy in action. During that month, CleanSpark produced 626 BTC but sold only 22.47 BTC, retaining over 96% of its production. The average price per BTC sold in January 2025 was approximately $100,412.
This operational success has been paired with aggressive expansion. In early 2025, CEO and President Zach Bradford celebrated not only the treasury milestone but also crossing a 40.1 exahash per second (EH/s) operating hashrate. At the time, the company was actively pursuing its goal of reaching 50 EH/s, with construction underway on new sites in Georgia, Tennessee, and Wyoming.
This growth demonstrates how the company balances capital allocation. While holding Bitcoin reduces immediately available cash for expansion, the company has continued to build out its infrastructure.
This includes bringing new facilities online, like a 12 MW site in Georgia contributing approximately 0.7 EH/s, and deploying next-generation machines to boost efficiency, such as the S21 XP Immersion miners planned for its Cheyenne, Wyoming, location, expected to contribute 5 EH/s in Q1 2025.
This contrasts with other corporate buyers where Strategy resumes Bitcoin buying as a primary corporate function, whereas CleanSpark generates its own.
The strategic implications of a large bitcoin reserve
For CleanSpark and its investors, the decision to maintain a large Bitcoin treasury is a double-edged sword. On one hand, it creates significant upside exposure. Any appreciation in the price of Bitcoin directly increases the value of the company’s balance sheet, potentially amplifying shareholder returns far beyond what mining revenue alone could generate.
On the other hand, it introduces substantial volatility and risk. A downturn in the crypto market could have a severe negative impact on the company’s asset base. This makes CleanSpark’s stock (NASDAQ: CLSK) a leveraged play on Bitcoin itself.
Investors are not just betting on the company’s ability to mine efficiently but also on the future price performance of the underlying asset; for instance, understanding when bitcoin breaches $86,000 can significantly impact the valuation of such holdings.
This large reserve also provides strategic optionality. The held Bitcoin can be used as collateral to secure favorable financing for new machines or infrastructure projects. It can also be sold to fund operations during periods of low Bitcoin prices or high mining difficulty, providing a buffer that miners with a sell-all strategy do not possess.
