Microsoft’s quarterly capital expenditure came in $5 billion below its own forecast, and newly examined satellite imagery suggests that setbacks at two partner-built data center campuses may help explain the Microsoft AI spending gap. The software giant’s finance chief, Amy Hood, told analysts on the earnings call that third-party cloud providers had contributed to the shortfall in AI infrastructure outlays, prompting Microsoft to trim its annual capex guidance by that same amount.
The disclosure rippled through the young neocloud sector, where investors are already questioning whether upstart operators can meet the multibillion-dollar commitments they have signed. Microsoft did not identify which partners were behind the delay, but research firm Aterio, using orbital reconnaissance, identified two projects as likely candidates: an IREN campus in Texas and a Nebius-linked facility in New Jersey.
Texas Buildout Shows Unfinished Work
IREN is constructing four data centers in the Lone Star State under a $9.7 billion agreement with Microsoft. A satellite pass on October 21 revealed that one structure, designated Horizon 4, still lacked backup generators and cooling apparatus, according to Aterio. The research firm cautioned that the building could miss its planned handover before the calendar year ends.
That would not be the first hiccup for the site. IREN has already acknowledged that equipment shortages pushed back Horizon 1, which Microsoft formally accepted in August. The earlier delay offers a preview of the supply-chain friction now visible at the later phase of the build.
New Jersey Project Faces Permitting Hurdles
The second campus, in New Jersey, is being developed by data center operator DataOne for Nebius as part of a $17.4 billion arrangement with Microsoft. Aterio estimates that roughly 140 megawatts of the project’s intended capacity may not arrive until 2027. According to Aterio data analyst Daud Shiraz, the developer initially struggled to secure permits for its original generators, then encountered further approval setbacks after pivoting to fuel cells.
Regulators fined DataOne $1 million in September for running generators without the necessary permits, adding a compliance dimension to the construction timeline. IREN and DataOne both declined to comment. Nebius did not respond to a request for comment.
A Wider Pattern of Slippage
The two campuses are not isolated cases. In October, Microsoft walked away from a separate agreement with another neocloud, Nscale, citing delays in power supply. Research firm Currence estimates that between 30% and 50% of planned data center capacity originally slated to come online this year could be deferred to 2027 or beyond, with electricity shortages and other construction problems among the causes.
Microsoft maintains that its infrastructure strategy is designed to absorb such shocks. A spokesperson said the company’s approach relies on flexibility and optionality, blending its own data centers with leased facilities and third-party providers. Still, the $5 billion capex reduction and the satellite evidence of unfinished work at partner sites illustrate how dependent the AI buildout has become on contractors whose timelines can shift.
For neoclouds, the stakes are acute. Their business models rest on converting large signed contracts into operating capacity on schedule, and any visible slippage invites scrutiny from investors and customers alike. The Microsoft AI spending gap may prove to be a temporary accounting adjustment for the buyer, but for the sellers, it is a reminder that promises on paper require generators, cooling systems and permits in the field.
