Microsoft is shrinking its roster of neocloud partners and has not decided which to drop, CNBC reported on Nov. 6, citing two people familiar with the matter, a day after Bloomberg reported tighter oversight.
Bloomberg News first reported on Nov. 5, according to Reuters, that Microsoft had tightened oversight of some data center projects at Nebius, IREN and Nscale and was debating whether to sign new neocloud deals. CNBC added that Microsoft wants to prioritize its own data center footprint, and that two people said it opted not to renew a deal with Oracle. Microsoft has signed deals with about half a dozen neoclouds, CNBC said, including CoreWeave, Nebius, Chronoscale, IREN, Lambda and Nscale.
A Microsoft spokesperson told CNBC the strategy is "built on flexibility and choice" and that the company regularly reviews investments against customer demand, including tracking delivery. Microsoft has not named the providers it is keeping.
Why Delivery Now Matters for Neocloud Capacity
A neocloud, a GPU-cloud operator, typically borrows against a long contract from one large tenant. If that tenant shrinks the list of operators it uses, the contract that backs each debt stack matters more than the headline megawatts. CNBC quoted IREN co-CEO Daniel Roberts saying on Nov. 5 that "the questions have undoubtedly moved from how big the contract is to whether it can be delivered, financed, and run at a profit."
Delivery is the stated test. Reuters said Microsoft will not exercise its option to more than double its Nscale agreement at a Texas data center, and that it left Nscale's Loughton, Essex, site weeks earlier after power connection delays pushed supply into the 2030s. Voltgrid covered the IREN timetable change and the Nscale Anthropic credit talks separately.
Neocloud Shares and Microsoft's Capex Figures

IREN, Nebius and CoreWeave shares fell about 17%, 14% and 10% at the Nov. 5 close, according to Reuters.

Reuters reported that on Nov. 5 Nebius ended down about 14%, IREN about 17% and CoreWeave about 10%. CNBC said on Nov. 6 that CoreWeave, Nebius and IREN shares were each down roughly half over the past month even after rallying that Friday; IREN rose 16% after reporting AI revenue of $200 million, more than double the prior quarter.
CNBC also noted that Microsoft finance chief Amy Hood said in October that some GPU cloud contracts were delayed until the first half of 2027, and that the company reported $45.2 billion of capital expenditures and finance leases in the quarter. That is a different measure from the $39.4 billion in property and equipment additions in our fiscal first-quarter story.
What Remains Unconfirmed on Microsoft's Neocloud Review
Both reports rest on unnamed sources. Microsoft has confirmed its review process, not any cut, and the company has not said which neoclouds stay. Bloomberg's report is paywalled, so Voltgrid relied on the Reuters and CNBC accounts of it. Voltgrid found no new statement from Microsoft, IREN, Nebius, Nscale or CoreWeave after Nov. 6. CNBC said CoreWeave and Nebius report quarterly results the week of Nov. 9, the first chance for either to describe its Microsoft work, as listed in our week-ahead calendar.
