AI Neocloud Stocks’ Relief Rally Fades as Microsoft Pullback Deepens Sector Fears
TREE NEWS reports: AI infrastructure stocks staged a sharp but short-lived rebound on Friday, as early gains evaporated amid fresh signs that major cloud customers are rethinking their outsourcing strategies. CoreWeave, which surged as much as 9.3% in morning trading, reversed course and briefly turned negative before recovering to trade up 4.4% by late afternoon. IREN’s rally was cut in half from a 24.6% opening jump to roughly 12%, while Nebius Group retreated from a 13.7% gain to about 2.4%.
The initial bounce was triggered by IREN’s better-than-expected fiscal first-quarter results, released after Thursday’s close. The company reported revenue of $228 million, topping analyst estimates of $221 million, with its AI Cloud business generating $200 million—a nearly threefold increase from $71 million in the prior quarter. Adjusted EBITDA came in at $66 million. IREN also disclosed a revenue backlog of $20.3 billion, underscoring persistent demand for AI compute.
However, the report also revealed cracks in execution. IREN said delivery of some data center infrastructure has been delayed due to Microsoft-requested network design changes and shifting supplier timelines. Its target of exceeding $4 billion in annualized revenue run-rate by year-end has been pushed to January 2027, with a possible slip to February. Meanwhile, capital commitments climbed to $18.95 billion as of September 30, up from $13.81 billion three months earlier, with roughly $15 billion in capex expected for the remainder of the fiscal year.
Microsoft’s Retreat Sends Shockwaves
The rally lost steam mid-session when reports emerged that Microsoft has begun phasing out some computing resources leased from Oracle and will not renew related contracts. The servers in question use older-generation Nvidia chips, which Microsoft said have become less useful as its technical requirements evolve. Oracle’s stock, up 3.8% earlier, plunged to a session low of $109.21, down as much as 5.2%, before paring losses.
The news compounded concerns sparked a day earlier when reports indicated Microsoft is tightening oversight of data center projects involving Nebius, IREN, and Nscale, exiting those deemed too risky and internally debating whether to sign new Neocloud agreements. On Thursday, CoreWeave, Nebius, and IREN fell roughly 10%, 15%, and 17%, respectively.
Policy Uncertainty Adds to Pressure
The sector’s volatility has been exacerbated by political developments. Following a strong Democratic showing in the U.S. midterm elections, investors are bracing for stricter regulatory scrutiny of data center construction. Analysts estimate that about 30% of projected new U.S. data center capacity through 2028 could face construction pauses, with Texas—a key market—under particular focus.
The broader concern is that third-party compute providers rely heavily on debt and equity financing to fund GPU purchases and data center buildouts before projects generate revenue. Delays in power access, equipment delivery, or customer requirement changes can disrupt revenue recognition and cash recovery cycles. CoreWeave’s highly leveraged expansion model has already drawn scrutiny from credit markets, and investors are growing less tolerant of capital-intensive business models with uncertain return timelines.
Key Takeaways for Investors
- Customer concentration risk is real: Neocloud providers depend on a handful of hyperscalers. Microsoft’s pullback from Oracle and its review of third-party contracts signal that demand from big tech is not unconditional.
- Execution matters more than backlog: IREN’s $20.3 billion backlog is impressive, but delivery delays and rising capex highlight the gap between contracted revenue and actual cash flow.
- Policy is a new variable: Midterm election results introduce regulatory risk to data center buildouts, potentially slowing capacity growth and raising costs.
- Volatility likely to persist: With financing conditions tightening and technology cycles shortening, expect continued swings in AI infrastructure names as the market recalibrates growth and risk.
