IREN Limited (NASDAQ: IREN), the bitcoin miner turned AI cloud provider, fell about 18% on November 5, 2026. Reports said construction delays at its Childress, Texas campus led Microsoft to push back planned AI spending. The selloff came hours before IREN reports fiscal first-quarter results after today’s close, and it dragged the PRISM Crypto Mining Index down nearly 15% by late morning.

Key Points

• IREN traded near $17.86, down about 17.7%, as of roughly 11:15 a.m. ET, according to PRISM MarketView index data.
• A report from The Information said delays at Childress led Microsoft to defer capital spending it had planned for the September quarter. Microsoft spent about $5 billion less than planned, though it is unclear how much of that relates to IREN.
• IREN’s $9.7 billion Microsoft contract covers four 50-megawatt phases at Childress. The first was accepted in August, and the other three are due in the December quarter.
• IREN reports fiscal Q1 2027 results after the close today, with a call at 5 p.m. ET.
• Every company in the PRISM Crypto Mining Index traded lower, with Cipher Mining down about 17% and CleanSpark down about 15%.

Why IREN (IREN) Shares Fell

The pressure on IREN (IREN) began with a report from The Information on November 4. It said delays at IREN’s Childress site led Microsoft to push back data center spending planned for the September quarter. Microsoft’s capital expenditures came in about $5 billion below plan, although the reports do not say how much of that gap traces back to IREN.

On Microsoft’s recent earnings call, CFO Amy Hood said some third-party capacity deliveries the company expected during the quarter had slipped. Then, on November 5, Bloomberg reported that Microsoft is tightening oversight of data center projects with IREN, Nebius Group and Nscale. According to that report, Microsoft is also weighing whether to sign more deals with outside infrastructure providers while it prioritizes its own build-out.

Bloomberg also reported three setbacks at the Texas campus: cabling problems that disrupted construction, a generator fire in April, and hardware delivery delays that IREN disclosed in August. Microsoft and IREN reportedly met last week and negotiated a revised timeline, which could push completion back by several weeks or months. PRISM MarketView did not find a public IREN statement responding to the reports as of late morning.

What Is at Stake in the Childress Contract for IREN (IREN)

The Microsoft deal sits at the center of IREN (IREN)’s shift from bitcoin mining to AI cloud services. Under the multiyear contract, Microsoft will spend $9.7 billion leasing GPU servers at Childress. The work is split into four 50-megawatt, liquid-cooled phases called Horizons 1 through 4.

IREN delivered Horizon 1 in August. Horizons 2 through 4, roughly three-quarters of the deal, are scheduled for the December quarter. Once all four phases run, management expects the contract to bring in about $1.94 billion a year. That is roughly half of the $4 billion in contracted annualized recurring revenue IREN is targeting by December 31. If phases slip past grace periods that end in early 2027, IREN could owe Microsoft delay credits.

The Microsoft relationship has also supported IREN’s financing. In October, PRISM MarketView reported that IREN unlocked $363 million from working GPUs as AI cloud financing heated up.

IREN (IREN) Earnings Tonight: What Investors Will Watch

IREN (IREN) reports fiscal first-quarter 2027 results after the market closes today and hosts a conference call at 5 p.m. ET. Analysts expect revenue of about $221.7 million, down 9% from a year ago, and an adjusted loss of $0.67 per share, according to Koyfin consensus data cited by 24/7 Wall St.

Investors will listen above all for two things: whether management confirms Horizons 2 through 4 remain on track for the December quarter, and whether the revised Microsoft timeline changes IREN’s year-end revenue target.

A Rough Day Across the PRISM Crypto Mining Index

IREN did not fall alone. As of late morning, the PRISM Crypto Mining Index was down about 14.8%, and every company in the index traded lower. Cipher Mining fell about 17%, CleanSpark about 15%, TeraWulf about 14.5% and Riot Platforms about 12%.

The selloff extends a broader tech rout that followed Tuesday’s midterm elections, with the Nasdaq down more than 4% on Thursday. AI data center stocks have also faced pressure in Texas. According to 24/7 Wall St., Democrat Gina Hinojosa, who has called for a moratorium on new data centers in the state, won the governor’s race.

Still, demand for AI capacity has not disappeared. On November 4, Riot disclosed a 15-year, roughly $28 billion lease with Anthropic covering 910 megawatts at its Corsicana, Texas campus. The same day, PRISM MarketView reported that TeraWulf secured Google credit support for its $19 billion Anthropic campus. Earlier this week, Cipher Digital booked its first AI lease revenue.

Today’s move therefore looks less like a verdict on AI demand and more like a test of which miners can deliver capacity on schedule. PRISM MarketView explored that theme when Elon Musk warned about the survival of smaller neoclouds.
