IREN Sinks 9% After Report Links It to Microsoft’s AI Spending Delay; Nebius Tumbles 11%, CoreWeave Slides 7%

IREN (NASDAQ:IREN) is under fresh pressure after a report tied delays at its main Texas campus to a shortfall in AI spending at Microsoft (NASDAQ:MSFT | MSFT Price Prediction). IREN stock is trading at $19.70, down 9%. The decline adds to losses in the prior session, when AI data center stocks sold off after Democrats won control of Congress in the midterm elections.

Childress is at the heart of IREN’s shift from crypto mining to AI cloud services. The company delivered Horizon 1, the first of four 50-megawatt liquid-cooled deployments for Microsoft, in August. In its Q4 FY2026 results, released August 27, IREN said it’s aiming $4 billion of contracted annualized recurring revenue to be running by December 31.

Microsoft’s Spending Shortfall Leads Back to Childress

A report citing unnamed sources said on November 4 that delays at IREN’s Childress site led Microsoft to push back capital expenditures (capex) it had planned for the September quarter. Microsoft spent $5 billion less on capex than planned, according to The Information. It isn’t clear how much of that gap came from IREN’s delays.

Microsoft’s earnings call took place last week. On it, CFO Amy Hood said, “Capital expenditures were $45.2 billion as some third-party capacity deliveries we expected in Q1 were delayed.” IREN’s multiyear contract calls for Microsoft to spend $9.7 billion leasing GPU servers at Childress, The Information noted.

Neocloud Stocks Slide as IREN Carries Its Own Overhang

Nebius Group (NASDAQ:NBIS) stock is at $125.88, down 11%. Meanwhile, CoreWeave (NASDAQ:CRWV) stock is at $44.89, down 7%. That leaves Nebius falling about as much as IREN, which shows how much of the pressure is coming from the whole sector.

Cipher Digital (NASDAQ:CIFR) is trading lower as well. CoreWeave and Nebius both declined in the prior session.

Election results are adding to the sector’s selloff. Democrat Gina Hinojosa, who wants an immediate moratorium on data centers in Texas, defeated incumbent Republican Gov. Greg Abbott, and that’s a direct concern for IREN’s Texas sites. Lawmakers could slow the build-out with a longer, costlier approval process, though an outright stop looks less likely.

Every neocloud name is taking that post-election discount. Yet only IREN is tied by name to Microsoft’s spending shortfall, which puts a company-specific question on top of the sector’s concerns.

How IREN’s Business Stacks Up Against Nebius and CoreWeave

IREN is a vertically integrated owner-operator that controls its own land, grid connections, buildings and GPU fleet, with Microsoft as its anchor customer. That setup gives the company cheaper financing backed by an investment-grade customer. It also concentrates risk in one campus and one counterparty.

Nebius runs a full-stack AI cloud with its own software layer, and a handful of large customers bring in much of its revenue. CoreWeave operates a pure-play GPU cloud that serves hyperscalers, AI labs and a growing list of enterprises, and Cipher Digital rents powered buildings under long-term contracts, which leaves the GPU spending to its tenants.

What IREN’s Earnings Report Could Reveal About Childress

IREN is scheduled to release Q1 FY2027 results after the market close on November 5. Per Koyfin, analysts expect IREN’s sales to fall 9% to $221.7 million, with an adjusted loss of $0.67 per share. Investors will be watching whether management confirms that Horizons 2 through 4 are still on track for the December quarter.

IREN co-CEO Daniel Roberts spoke on the August 27 call. On the bullish side, he stated, “Our 2026 capacity is largely sold out.” The company also secured more backing. It reported $14 billion in committed financing and prepayments. Bears can point to IREN’s own warning that much of the December capacity comes online late in the quarter, which moves reported revenue mainly into the March quarter, and to a possible Texas moratorium that could complicate future expansion.

Macro data adds another layer for IREN, with weekly jobless claims out on November 5 and the October payrolls report due November 6. A conservative investment approach could make sense while the Childress delivery question remains open.
