IREN Stock News, October 2026: What Has Driven the Selloff and What to Watch Next

IREN closed at $25.50, down 8.4%, on the October 21 session — capping a month shaped by Gartner's 80%-neocloud-collapse forecast, a SemiAnalysis critique of its British Columbia data centers, and CoreWeave debt stress, against which a reported Anthropic deal and a new 300 MW European campus licence stand as the key recovery catalysts to monitor.

IREN shares closed at $25.50 on the session of October 21, down 8.4% — a move that no coverage report has attributed to a single identifiable cause, though it arrived near the end of a month in which the neocloud category as a whole experienced a significant sector-wide selloff. The question investors and analysts are now asking is not merely what pushed the stock lower in October, but whether the forces behind the decline are transitory or structural — and whether the company's own operational trajectory is sufficient to change that calculus.

The sectoral backdrop was defined by two overlapping pressures. Gartner's forecast that 80% of neocloud companies would cease to exist by 2030 landed on a market already unsettled by visible stress in CoreWeave's debt markets, where the company's 2032 bonds reportedly fell below 80 cents on the dollar with yields reaching 14.5%, while CoreWeave's stock accumulated a four-day loss of 28.2% — a period in which IREN fell 30.3% on a cumulative basis, according to one report. Separately, research firm SemiAnalysis published a critique of IREN's legacy British Columbia data center assets; coverage attributes a 4% single-session decline to that report, and IREN responded by publicly pointing to Nvidia's validation of its AI infrastructure. Coverage also linked the withdrawal of the Firmus $5 billion IPO during the same period to a broader neocloud confidence crisis.

The month's most consequential unresolved item is a reportedly secured multi-year cloud agreement with Anthropic. Multiple coverage sources report the deal and note that IREN's stock initially rallied on the news; a separate report then recorded a 5% decline when the agreement remained officially unconfirmed, citing shaken investor confidence. IREN's co-CEO separately offered a public reassurance that the company carries no debt — coverage reports that statement arrested a 6% intraday slide on a different occasion and allowed the stock to recover. Together, these episodes illustrate the pattern that defined IREN's October: a fundamental positive surfaces, but uncertainty over its status limits the durability of any bounce.

The company's fundamental transformation is real on the metrics, though the costs are commensurate with the ambition. FY2026 revenue reached $707 million, a 41.1% increase, and AI cloud revenue for the full fiscal year grew nearly eightfold to approximately $128.8 million — the first fiscal year in which that segment surpassed Bitcoin mining as IREN's primary revenue source. The net loss for the year was $703 million, driven primarily by non-cash items. Slicast's compilation from SEC XBRL filings shows capital expenditure in FY2026 at $3.00 billion, a 628.8% increase from $411 million in FY2025, and a capex intensity of 424% of that year's revenue — placing IREN fourth of seven neoclouds by intensity and third by absolute spend, with Nebius leading on intensity and CoreWeave leading in absolute terms. Q3 FY2026 results showed AI cloud revenue up 94% quarter over quarter to $33.6 million, alongside disclosure of a five-year Nvidia contract valued at $3.4 billion. The most recent earnings release, for Q4 FY2026, produced an EPS of -$1.89 against a consensus estimate of -$0.55 — a 243% miss — with coverage reporting a 12.5% decline.

The company's pipeline adds geographic scope but operates on multi-year timelines. IREN launched IREN Europe in October and secured a licence for a 300 MW AI data center campus in Badajoz, Spain, targeting a 2028 operational date. In Australia, coverage reports a 900 MW data center campus planned for Wagga Wagga with a 2029 grid-connection target, alongside a 900 MW Redbank proposal — though coverage specifically notes that project carries a key caveat. GPU rental pricing provided an intermittent tailwind: coverage reports that as Nebius raised GPU rates by 17–21%, IREN climbed 6% in a single session. Not all institutional commentary has been bearish: Wedbush analyst Dan Ives characterised the AI infrastructure panic as "overdone," and ARK Invest reportedly purchased $14.7 million of CoreWeave shares during the selloff — signalling that at least some institutional players are positioning for a category recovery rather than exiting.

Three signals will most directly determine IREN's near-term trajectory. First, official confirmation or denial of the reported Anthropic contract would resolve the largest source of stock-specific uncertainty; the stock has already traded sharply on both sides of that headline within a single month. Second, management's ARR target calls for annual recurring revenue to exceed $4 billion by fiscal year-end; monthly AI cloud revenue disclosures will be the most granular indicator of whether the ramp from $128.8 million in FY2026 is tracking toward that goal. Third, the Badajoz campus — IREN's first international facility — must progress from licence to construction financing and an anchor customer; how that project is structured and capitalised will test whether the European expansion can replicate the model the company has built domestically. The fundamental tension at the core of IREN's investment case — a verified, high-speed AI cloud revenue ramp against a capex intensity that exceeded revenue by a ratio of more than four to one in FY2026 — will not resolve in a single quarter, but the coming months will clarify which side of the argument is gaining ground.
