IREN heads into the week at $39.75 — up 8% on Monday and 9.5% on the week — yet the short base has grown heavier still, deepening a conflict between record bearish positioning and a stock that keeps rallying.
The short interest story has not changed direction. It has intensified. Short interest reached 36% of the free float by Monday's close, with roughly 102 million shares held short — up 8.4% on the week and nearly 58% above the level from a month ago. Every session in the history window shows a higher short count than the last. Availability has tightened further to 1.3%, the 52-week low, meaning fewer than one and a half shares remain available to borrow for every hundred already lent out. A month ago availability sat near 46%. That compression has been relentless: from 33% in early July to single digits by mid-month, then sub-2% for the past two weeks. The cost to borrow has moved higher — up 35% over the past month to 1.08% — but remains historically cheap, consistent with earlier notes: the incumbents locked in favourable rates long ago, and the borrow market is now effectively closed to new entrants.
What has changed this week is the options read. The put/call ratio dropped to 0.87 — almost 1.75 standard deviations below its 20-day average of 1.0. For three consecutive weeks this column noted the PCR running above average, signalling defensive hedging from options traders. That has now reversed sharply, with call positioning pushing back to levels not seen in over a month. The prior two weeks showed PCRs above 1.05; Monday's reading is the lowest since early July. That flip in options positioning, set against a short base that is still growing, is the week's central tension. Short sellers are adding; options traders are turning more constructive.
The analyst community has remained consistently bullish, with a cluster of Buy and Outperform ratings maintaining targets well above the current price. HC Wainwright raised its target to $90 on July 22, while Canaccord Genuity held firm at $79 and Macquarie kept its Outperform and $90 target the same week. The consensus analyst recommendation registers as a hold by count, but the active target range — $79 to $99 — sits roughly double the current price. Bulls point to $2.8 billion in new multi-year AI cloud contracts and ~85% of the ARR target already under contract. Bears counter that execution risk is real: GPU deployment timelines, revenue ramps, and selling into a competitive compute market are all live concerns. The ORTEX short score of 68.9 places the name in roughly the bottom 4th percentile for short-side risk, confirming that the data collectively reflects a heavily contested stock. EPS surprise factor ranks in the 90th percentile, a meaningful positive outlier, but forward EPS momentum sits near the bottom of the universe.
The sector has broadly recovered this week alongside IREN. CIFR gained 11.6% on the week, CORZ added 10.1%, and HUT rose 7.2%. IREN's 9.5% gain tracks the group, suggesting the move is sector-driven rather than a stock-specific catalyst — which makes the divergence in options sentiment more notable, since call buyers are leaning in precisely as the short book grows.
Earnings land on August 28. The two most recent quarterly prints produced muted immediate reactions — down 4% and flat, respectively — though the five-day windows were more variable. The setup heading into that date will be worth watching closely: whether the short base begins to cover, or availability tightens further toward zero, is the positioning question that frames everything that follows.
