Oracle Rental Unwind Signals Wider Review of Microsoft's AI Compute Buying

Microsoft is allowing an agreement to rent artificial-intelligence computing capacity from Oracle to lapse, according to a Bloomberg report citing people familiar with the matter, carried by Handelsblatt and, through Taiwan's Central News Agency, by Liberty Times. The arrangement sits in the market for AI compute — the processors and datacentre capacity that model developers rent rather than own — and the reported decision is described as part of a wider review of cloud partnerships valued in the billions of dollars. Neither the terms of the agreement nor the volume of capacity concerned has been disclosed in these accounts.

Positions are only partly on the record. Handelsblatt quotes an Oracle spokesperson telling Reuters that demand for the company's AI infrastructure remains strong, including for older generations of graphics processors. Liberty Times, citing Central News Agency, reported that neither Microsoft nor Oracle had immediately responded to Reuters requests for comment. The two accounts therefore differ on Oracle's response, and neither identifies the insiders on whom the Bloomberg reporting rests; neither company has confirmed that a review is under way.

According to the Bloomberg reporting as relayed by Liberty Times, Microsoft has in recent months begun phasing out its use of Oracle-rented compute after deciding not to renew, because its requirements changed and the rented capacity increasingly failed to meet them, lowering its value. Handelsblatt frames the report as a further indication that the software group is rethinking how it procures compute in order to extract more from its large AI investments — a characterisation attributed to the reporting rather than confirmed by Microsoft.

The reported review appears to extend beyond Oracle. Handelsblatt, citing Bloomberg, reports that the AI cloud company Iren said on Thursday it had delayed some infrastructure deliveries after Microsoft requested changes to network design, and that Microsoft is tightening control over certain datacentre projects operated by so-called neocloud providers including Iren, Nebius and Nscale, amid delays and rising costs. Those details are attributed to Bloomberg's sources and have not been independently confirmed in the supplied material. No timetable has been disclosed for the Oracle unwind, and neither company has said whether any step beyond non-renewal is contemplated.
