Additional detail from the update shows CleanSpark's September output averaging 17.64 BTC per day, bringing the company's cumulative 2026 production to 5,432 BTC. The update did not elaborate on the reasons for the month-over-month decline.
CleanSpark is a US-based Bitcoin miner whose shares trade on the Nasdaq exchange under the ticker CLSK. Publicly listed mining companies routinely disclose monthly production figures, typically including total BTC mined, daily averages and year-to-date totals, as part of regular investor communications. Under that routine, the company's next monthly update would extend the 5,432 BTC running total for 2026.
Monthly output can fluctuate with factors such as network difficulty, energy availability and changes to a miner's fleet. Bitcoin's difficulty automatically retargets roughly every two weeks to keep new blocks arriving about every ten minutes, so the amount of BTC a miner earns for a given amount of computing power can move from month to month even when its hardware footprint is unchanged. Production volume is also only one operating metric: it does not by itself capture a miner's energy costs or revenues.
