IREN arrives at its August 27 print with bears making a small retreat — but the short base remains one of the most entrenched in digital infrastructure, and the borrow market is still effectively sealed.
The most notable development since Monday's earnings preview is the price action itself. IREN jumped 6% on August 25 to $42.21, extending a 14% one-month rally, while short interest has quietly eased for the first time in weeks. The short position has pulled back from the 100.6 million shares flagged in the previous note to 97.4 million — a 2.4% single-day reduction and a 2.4% decline on the week. That brings short interest as a proportion of free float down to 34.4%, still enormous by any peer-group standard but the first meaningful retreat since the August 13 dip that was itself quickly reversed. The direction matters heading into a catalyst: some bears are lightening ahead of the print rather than holding through it.
The borrow market tells a more complicated story than the short interest headline suggests. Availability has tightened further to just 1.5% — down 9% on the week and barely above the 52-week floor of 0.70% recorded on August 4. Every share in the lending pool that can be lent is already lent. Cost to borrow, at 1.11%, is essentially flat on the week and low in absolute terms; this is a market of incumbents sitting in legacy positions, not new shorts paying a premium to get in. The lending pool is not open to fresh entrants. That combination — modest short covering, but near-zero availability — means any acceleration in covering tomorrow could run into limited supply, with few new shorts able to step in to fill the gap.
Options positioning has shifted since the extended note published two days ago, and the direction is worth flagging. The put/call ratio rose back to 0.81 on August 25 from a mid-week low of 0.71, sitting roughly half a standard deviation below the 20-day average of 0.85. The recent trend is a sharp drop from late July, when the PCR ran above 1.05 — a significant rotation from defensive positioning toward calls. That call-heavy tilt has moderated slightly in the final session before the print, but options traders remain more bullish than their 20-day baseline. Twelve buy-rated analysts with a mean price target of $80.19 — nearly double the current price — provide the backdrop. The most recent target raise came from HC Wainwright in late July, lifting to $90; Cantor Fitzgerald's $99 target, set in late May, remains the Street high. The wide gap between target and price reflects both the analysts' conviction and the market's scepticism.
That scepticism has an institutional dimension worth noting. The top holders show substantial recent accumulation: Bank of America added 12 million shares, BlackRock added nearly 8.9 million, and Goldman Sachs added nearly 7 million — all reported as of Q2 end. Norges Bank entered as a new holder with 5.2 million shares. Against that backdrop of institutional buying, the entrenched short base is a genuine standoff. Bulls are buying the AI cloud and Microsoft partnership thesis; bears are leaning on crypto market sensitivity and a profitability profile that still carries a negative PE and negative book value. The EV/EBITDA of roughly 4x is the one multiple that looks undemanding, but the earnings track record — a 4% day-one drop in May followed by a recovery — gives neither side a clear historical edge.
Peers moved broadly higher on August 25: KEEL gained 8%, HUT gained 7.5%, CLSK and RIOT both gained roughly 6-7%. The sector lifted in unison on the day, making it harder to read IREN's individual 6% move as a signal. What to watch at tomorrow's close: whether short interest sustains its first genuine multi-day decline since mid-August, and whether the print is enough to push availability off its near-zero floor or drive it lower still.
