CleanSpark has given back the gains it made last week, falling 13% to $11.06, and the short interest that looked conspicuous against a rising stock now looks more comfortable for the bears.
The dynamic has flipped since the previous note. A week ago, CLSK was back at $12.75 with 29% of the float short and the stock grinding higher — a tension between structural skepticism and sector momentum. That tension has resolved in the shorts' favour. The stock is down 13% on the week and 20% over the past month. Short interest at 29.2% of the free float — roughly 74.7 million shares — has barely moved, ticking up just over 1% on the week. Bears are not rushing to cover. They are, in effect, being rewarded for staying put.
The lending market tells a similar story. Borrow availability is at 35%, still tight by historical standards but meaningfully looser than the lows around 20% seen in late July. Cost to borrow has eased sharply, falling 22% on the week to just under 0.5% — well below any level that would be painful for a short holder to maintain. The ORTEX short score of 69.3 ranks in the 5th percentile of the universe, flagging CLSK as one of the most heavily shorted names covered, and the score has drifted slightly lower over the past two weeks rather than spiking. The options market does not show elevated defensive activity either. The put/call ratio is 0.46, actually below its 20-day average of 0.48, running near the lower end of its 52-week range. The read across all these signals is consistent: this is not a heated, expensive short — it is a large, patient, cheap one.
The sell-side disagrees with the bears on direction. Every analyst change in the recent window has been a Buy or Overweight, and several firms lifted targets ahead of the August earnings print. B. Riley raised its target from $19 to $26 on August 3. Cantor Fitzgerald held at Overweight with a $26 target following results. Chardan maintained its Buy at $21 in the days after. The consensus mean target sits near $24, implying roughly 115% upside from current levels — a substantial gap that reflects the Street's confidence in the pivot toward AI and high-performance computing alongside bitcoin mining. The bull case centres on the anchor lease deal in Texas, over $1 billion in combined liquidity, and the data centre opportunity. Bears point to execution risk on the Sandersville project, the company's dependence on bitcoin as an asset, and the risk of equity dilution if the AI/HPC pipeline requires external funding.
That earnings backdrop matters for context. The most recent print — delivered in early August — saw the stock fall around 9% the following day and extend to nearly minus 15% over the subsequent five sessions. The pattern before that was similar in direction, though the prior note-cycle noted an 8.7% recovery into the week of August 25. The stock has now erased that recovery and then some, closing below where it was in mid-August. Among close peers, the weakness is sector-wide: MARA fell 13.5% on the week, RIOT dropped 16.5%, and HIVE shed 12%. HUT and CORZ held in somewhat better, each down around 10–11%. CLSK's drawdown is roughly in line with the peer group, suggesting this is bitcoin-driven selling rather than company-specific pressure.
With the next earnings event not scheduled until December, the near-term catalyst set is thin. The key variables to track are borrow availability — whether it continues to ease or tightens again if bitcoin weakens further — and whether the 74-million-share short position begins to show any signs of genuine unwinding or, conversely, adds to its position as the stock tests new lows.
