IREN heads into its August 27 earnings release with short sellers continuing to trim — but the borrow market, while fractionally looser than its nadir, remains one of the tightest setups in the digital infrastructure space.
The short position has pulled back further since the previous note. Short interest has fallen to 93.9 million shares, down another 5.5% on the week and off roughly 8% from the 102 million-share peak logged in early August. That figure still represents 33% of the free float — and is still 36% higher than it was a month ago, a buildup that remains structurally significant. The borrow side has shown the first real movement in weeks: availability has climbed to 5.2% from a floor of 0.70% recorded on August 4 — the tightest reading in the dataset's history. That loosening is meaningful but should be kept in context. Fewer than six shares remain available for every hundred already lent out. The previous note described the market as "effectively sealed for new entrants"; the door has opened a crack, but it is not open. Cost to borrow has eased further to under 1%, down 16% on the week, consistent with incumbents sitting in legacy positions at cheap rates rather than any genuine reopening of supply. The ORTEX short score of 68.9 ranks in the bottom 6th percentile of all US names — that has barely moved all month, signalling that the broader short-pressure complex around IREN remains intact even as the share count drifts lower.
Options positioning has shifted meaningfully and tells a different story to the short book. The put/call ratio has dropped to 0.81, more than 1.4 standard deviations below its 20-day average of 0.95 — the most call-heavy reading in weeks. Through late July and into mid-August, the PCR ran above 1.0 consistently, reflecting caution ahead of what looked like an asymmetric event. That has now reversed sharply. Traders are tilting toward upside exposure heading into the print, a notable contrast with the still-elevated short base. The stock's own price action supports the shift: IREN is up 6.9% on the week and 14% on the month to $44.06, outperforming most peers. WULF gained only 1.8% on the week, CORZ fell 4.0%, KEEL dropped 9.5%, and MARA shed 8.8%. IREN is moving in the opposite direction to the group, which adds weight to the idea that something stock-specific — rather than sector beta — is driving buying interest ahead of results.
The Street is broadly constructive. Recent analyst activity has been directionally bullish, with multiple firms maintaining Buy or Outperform ratings and targets clustered in the $79–$99 range, well above the current price. HC Wainwright lifted its target to $90 in late July while reiterating Buy. Macquarie held its Outperform and $90 target. Cantor Fitzgerald carries the highest target in the group at $99. The bull case centres on IREN's pivot toward AI cloud infrastructure — leveraging renewable energy assets and partnerships with Microsoft — with near-term growth from its Prince George and Horizon 1 data centre facilities. The bear case is narrower: the shift away from bitcoin mining introduces execution risk, and EPS momentum is deeply negative, with the 30-day and 90-day EPS momentum scores both ranked in the 3rd percentile. The company is not yet profitable — the PE and price-to-book multiples are both negative — but the EV/EBITDA of roughly 4x has been compressing over the past month, suggesting the market is pricing in faster near-term cash generation.
Institutional flow adds a layer of interest. Bank of America added nearly 19 million shares in its most recent filing, bringing its position to 21 million — a near-tenfold increase. BlackRock added 8.9 million shares to reach 13.3 million. State Street added 3.8 million. That scale of institutional accumulation alongside a 33%-of-float short position creates a structurally compressed setup: large holders are adding while a heavy short base tries to exit into improving prices. The earnings history from recent quarters is limited — the May print produced a modest one-day move of -4% before recovering 5% over the following week — but the magnitude of the short base and the tightness of the borrow market mean the August 27 release carries more mechanical force than a typical event.
What to watch into the print: whether the borrow market continues loosening — giving new shorts room to enter if results disappoint — or snaps back to sub-1% availability, which would concentrate all the pressure on incumbents already sitting on a crowded, costly position.
