CleanSpark says it will stop publishing monthly Bitcoin mining operational updates and move to standard quarterly reporting as its business expands further into large-scale data center development. The change was disclosed in the company’s September 2026 operating report released October 9.
The reporting change is easy to overlook because the release also includes a full set of mining numbers. But for anyone tracking public Bitcoin miners month by month, it is meaningful: one of the industry’s largest operators is moving away from the monthly production cadence that has become common across listed mining companies.
CleanSpark said in its official October 9 operational update that it will transition to quarterly reporting “consistent with peers in the energy and data center sectors” and discontinue monthly operational updates.
The final monthly snapshot shows 529 BTC mined
For September, CleanSpark reported 529 BTC produced, with peak daily production of 18.99 BTC and average daily production of 17.64 BTC. The company said it had produced 5,432 BTC during calendar 2026 through September.
Its operational hashrate remained at 50 EH/s, while average operating hashrate was 36.0 EH/s. CleanSpark listed peak deployed fleet efficiency at 16.07 J/TH across 199,745 deployed miners.
CleanSpark sold more Bitcoin than it mined in September
CleanSpark began September with 13,703 BTC, mined 529 BTC, sold 2 BTC at spot and sold another 700 BTC through call-option exercises. It ended the month with 13,530 BTC.
The company reported an average realized price of $72,928 per BTC sold, using a calculation that includes net sale proceeds plus net premiums generated. It also said 3,475 BTC of its September 30 holdings were posted as collateral or recorded as receivables related to derivative transactions.
That treasury activity adds context to BitcoinVersus’ earlier report on CleanSpark’s August production and 1.8 GW power portfolio. September production fell from the 593 BTC reported for August, while the company continued using its treasury more actively.
The company is increasingly reporting like a data center developer
The reason CleanSpark gave for the reporting change is its broader business evolution. The company now describes itself as a data center developer and says it controls more than 1.8 GW of power, land and data centers across the United States.
Its September update also repeated that a subsidiary closed $2.276 billion of 7.875% senior secured notes due 2031. The financing is intended to fund the Sandersville data center build-out tied to a lease that CleanSpark expects to generate about $6.6 billion of contracted revenue over its initial term.
The financing itself was previously disclosed and covered by BitcoinVersus when CleanSpark closed the $2.276 billion funding package for the 175 MW Sandersville AI campus. The new development is that CleanSpark is now explicitly changing how frequently it reports mining operations.
The SEC-filed September 25 financing announcement confirms that the notes carry a 7.875% coupon and mature in 2031.
Monthly mining visibility will now decrease
For investors, miners and industry analysts, the practical effect is less frequent company-issued mining data. Monthly production, average hashrate, fleet efficiency, utilized megawatts and treasury movements have made it possible to compare operating trends quickly across public miners.
Moving to quarterly reporting does not mean CleanSpark is leaving Bitcoin mining. Its September release says Bitcoin mining continues to monetize contracted power while the company develops other computing uses. But outside observers will now have fewer official checkpoints between earnings reports.
That matters particularly when network conditions change quickly. BitcoinVersus has previously explained why rising Bitcoin difficulty makes fleet efficiency increasingly important; quarterly reporting means some operating changes may now be visible later than they were under a monthly schedule.
What is confirmed
CleanSpark’s September 2026 monthly update is its last planned monthly operating report under the newly announced cadence. The company says future reporting will move to a standard quarterly schedule.
The September snapshot shows 529 BTC mined, 702 BTC sold, 13,530 BTC held at month-end, 50 EH/s of operational hashrate, 36 EH/s of average operating hashrate, 1.8 GW of contracted power and 808 MW utilized.
Editor’s Note: CleanSpark’s September operating figures are unaudited company-reported metrics. The move to quarterly reporting is confirmed by the company’s October 9 release; this article does not assume that the reporting change alters CleanSpark’s Bitcoin mining strategy beyond what the company stated.
