Why Is CLEANSPARK INC (CLSK) Stock Down Today?

CleanSpark Inc. stock fell 9.96% to $11.66 on Thursday, marking one of its most volatile sessions in recent weeks. The decline came amid mixed options activity in the Tradr 2X Long CLSK Daily ETF, as well as broader short-selling pressure in the information technology sector. The stock opened at $12.80 but dropped steadily throughout the session, reaching an intraday low of $11.52 before settling at $11.66.

What Happened

The stock gapped down 1.2% at the open, following a prior close of $12.95. By the end of the session, it had fallen to $11.66, a price that represents a new 52-week low. Cboe data showed unusual options activity in the leveraged ETF tied to CleanSpark, with a notable $733,000 call premium traded. This activity suggests heightened speculative interest but did not provide a clear directional signal for the stock itself. Meanwhile, external reports highlighted increased short interest in the broader tech sector, including in CleanSpark, which has seen one insider sale of $622 in the last 90 days. The CEO, Monnig Taylor, sold shares on August 14, 2026.
