IREN has given back nearly 19% this week — the short-covering rally that dominated the prior note has stalled, and the bears are rebuilding.
The reversal in positioning is the week's clearest story. Short interest jumped 7% in a single session on June 9 to 55.8 million shares, now representing 19.7% of free float. That erases a meaningful chunk of the covering seen through late May, when shorts had pulled back to roughly 51 million shares after the squeeze forced a rapid unwind from 66 million in mid-May. The stock that climbed 46% in a month to $66.60 is now trading at $54.02, and new short positions are being rebuilt into the weakness. Availability has tightened back to 47%, compared with above 100% as recently as early May — still not at the extreme levels seen in mid-May (21.5%), but the direction is firmly tighter. Cost to borrow, while still low in absolute terms at 0.77%, has risen 36% on the week, consistent with fresh demand for borrows rather than simple covering activity.
Options positioning reflects the same caution. The put/call ratio has jumped to 0.82, the highest reading of the past year and nearly 2.7 standard deviations above its 20-day average of 0.68. That's a sharp one-day move — Monday's PCR was 0.71, well within the normal range. The shift suggests options traders moved defensively in response to the price break rather than anticipating it.
The Street, however, is not capitulating. Multiple analysts raised targets in the past two weeks — B. Riley lifted its target to $96, Cantor Fitzgerald to $99, and Macquarie maintained its $90 Outperform. The consensus mean target of $81 implies roughly 50% upside from current levels. The lone dissenter remains JPMorgan, whose Underweight rating carries a $46 target — now above the current price after the week's drop, giving that bearish call more technical relevance than it had at $66. The bull case centres on IREN's pivot toward AI infrastructure, partnerships with Microsoft and NVIDIA, and a $3.7bn ARR target for end-2026. Bears point to customer concentration risk, dependence on timely GPU deployment, and negative EPS momentum — the EPS momentum factor scores rank in the bottom 1% of the universe on both 30-day and 90-day windows. The ORTEX short score of 66.5 has barely moved despite the price action, suggesting the overall short setup remains persistently elevated rather than transitioning to a new regime.
Institutional flow adds a layer of context. D.E. Shaw trimmed its position by 5.25 million shares through March 31, and Morgan Stanley cut by 3.6 million over the same period. BlackRock moved the other way, adding 3.8 million shares through May. Insider data is stale — both co-CEOs sold shares at $33 in September 2025, well below current levels, and no more recent filings are available.
Earnings aren't due until August 28, leaving the market without a near-term fundamental catalyst. The next session to watch is whether short interest continues to build above 19% of float — the level where the squeeze first began in earnest in early May — and whether peer names like CIFR and HUT, both down 12-15% on the week, stabilise or drag the sector lower.
