Microsoft has started turning off AI computing capacity it had been renting from Oracle and chose not to renew a contract built around older Nvidia chips, according to a Bloomberg report from Nov. 6 cited by crypto.news. The rented servers had grown less useful as Microsoft’s technical requirements shifted, the people familiar with the matter said.
The original arrangement dates to 2023, when Oracle agreed to supply hardware for Microsoft’s AI-powered Bing search engine. Microsoft declined to comment, and Bloomberg said the full size of the contract could not be determined, crypto.news reported.

Key facts
- Microsoft declined to renew the Oracle agreement, and Bloomberg described the equipment involved as older-generation Nvidia chips without naming a specific model.
- Oracle said GPU capacity that came up for renewal in its fiscal first quarter was renewed or sold to other customers on long-term contracts at prices 20% above prior agreements.
- Oracle said most of the GPUs covered by those renewals were at least four years old.
- Microsoft has committed more than $80 billion to renting capacity from outside cloud businesses, including CoreWeave, Nscale and Nebius.
- Crypto Briefing, citing a June 16, 2026 Business Insider report, said a separate lease worth over $3 billion in Oracle Cloud Infrastructure collapsed over Oracle’s lack of FedRAMP certification.
Oracle pushes back on demand questions
Oracle answered the report the same day. In its statement on X, the company said demand for its cloud infrastructure held up among earlier GPU generations and pointed to comments from its latest earnings call about renewal pricing. It described the 20% premium as evidence that existing hardware still attracts buyers as newer chips arrive. The statement addressed demand across its infrastructure business; it did not give the value of Microsoft’s departing contract or name the customers taking on the freed capacity.
The two reports do not describe the same arrangement. Crypto Briefing’s account concerns a negotiation that fell apart in June over a federal security certification, with no signed multi-year agreement ever placed; the publication said Oracle called the details “inaccurate” at the time and stressed that Microsoft remains both a partner and a customer. crypto.news’s account concerns an earlier, active rental contract that lapsed when Microsoft passed on renewing it.

An $80 billion rental bill and tighter oversight
The Oracle pullback follows a costly push into outside computing. Bloomberg reported that several Microsoft executives have grown frustrated with supplier costs and delivery delays, prompting the company to tighten oversight of data centre construction, withdraw from projects it deems risky and debate signing more agreements with those providers. In separate reporting on Nov. 5, Bloomberg said Microsoft had sent staff to supplier sites to check construction standards, including facilities being developed by Nebius, IREN and Nscale. Microsoft told Reuters its strategy combines its own data centres, leased facilities and outside partnerships for flexible capacity.
Mining companies that pivoted to AI hosting sit on the receiving end of that scrutiny. IREN moved its target for more than $4 billion in annual recurring revenue from December into early 2027 after customer-requested network changes slowed its Microsoft deployment. Its AI cloud revenue reached $200 million in the September quarter, Bitcoin mining revenue dropped 58% from the prior quarter to $28 million, and the shares closed nearly 17% lower on Nov. 5.
Oracle and Microsoft have also linked up on other AI work. In a June 2024 announcement, the companies and OpenAI outlined an arrangement to extend Microsoft’s Azure AI platform through Oracle Cloud Infrastructure.
Why it matters
Renting capacity from rivals has been Microsoft’s shortcut around the multi-year build times of new data centres, so any retreat signals that the blended cost and reliability of that route is under review. For cloud suppliers, the episode puts compliance and hardware age alongside price as selling points. Bitcoin miners that converted power sites into AI hosting now face customers who audit construction and delivery more closely, which makes contract execution as important as signed capacity.
What to watch
Watch which providers Microsoft taps for the capacity it sought, whether the Texas data centre arrangement tied to earlier Oracle and OpenAI discussions advances, and whether Oracle changes course on pursuing FedRAMP certification for its public cloud. IREN’s revised early-2027 revenue target is the next concrete delivery checkpoint.
