Update What changed

CNBC says Microsoft is still evaluating its neocloud relationships and has not decided which providers it may stop using. The report names six companies it has worked with: CoreWeave, Nebius, Chronoscale, IREN, Lambda and Nscale.

Two sources told CNBC that Microsoft chose not to renew a deal with Oracle. That is a specific reported change, distinct from the broader review, and does not establish that Microsoft is ending its other supplier relationships.

Microsoft told CNBC that it regularly reviews infrastructure investments against customer demand and uses a mix of its own data centres, leased facilities and third-party partnerships. The company’s stated approach is to adjust plans as circumstances change; the report does not give a timetable for any further decisions.

Update What changed

Microsoft has been actively turning off AI computing capacity it rents from Oracle over the past few months, CNBC reports in an account citing Reuters’ report of Bloomberg’s reporting. That adds an implementation detail to the already reported decision not to renew the contract.

The reports place the move within a wider reassessment of Microsoft’s cloud partnerships, involving billions of dollars. They do not specify how much capacity has been switched off or when the process will finish.

The distinction matters: a non-renewal is a future contract decision; switching off rented capacity over several months indicates that the change is already under way. How much of Microsoft’s AI infrastructure should it build itself, and how much should it leave to outside providers?

Update What changed

Microsoft asked IREN to upgrade networking equipment at a data centre intended for its use, delaying the facility’s expected start from this year to January or February, CNBC reports. IREN said it handed over the capacity in August.

Microsoft finance chief Amy Hood said some cloud contracts involving GPUs had been delayed until the first half of 2027, affecting Azure growth, according to CNBC. The report does not identify those contracts or say how much capacity is affected.

Microsoft reported $45.2 billion in capital expenditure and finance leases in its latest quarter, and said spending would accelerate in the second half of its fiscal year. The added detail is less about a supplier list than the practical timetable: turning AI infrastructure commitments into usable capacity is proving a slower business than signing the deals.
