Microsoft has decided not to renew its contract for AI computing resources leased from Oracle and has been winding down its use of them, Bloomberg reported on November 6, 2026. In 2023, the two companies signed a multiyear agreement under which Microsoft used Oracle's computing resources for inference processing for the AI models behind Bing's conversational search. Inference refers to running a trained AI model to generate responses to inputs. In the original setup, Microsoft's Azure connected to and managed computing resources on Oracle Cloud Infrastructure (OCI). The latest report suggests Microsoft may be reviewing the AI computing capacity it procures externally, but the scale of the equipment involved and where the workloads are moving have not been disclosed.
Microsoft reportedly won't renew its Oracle AI computing contract
According to Bloomberg, Microsoft has declined to renew its contract for AI computing resources leased from Oracle and has been winding down its use over the past several months. The reported reason is that the older-generation NVIDIA GPUs installed in the equipment no longer meet Microsoft's changing requirements. However, the report is based on people familiar with the matter, and Microsoft and Oracle have not formally announced an end to the contract. The specific date and value of the contract that was not renewed, the models and quantities of the GPUs involved, and when the wind-down will be complete have also not been made public.
Oracle, for its part, told Reuters through a spokesperson that demand for AI infrastructure, including older-generation GPUs, remains strong. That is a view on demand for Oracle's AI infrastructure in general. It does not mean that all of the computing resources Microsoft is giving up have been lined up for new customers. The report alone also makes it impossible to judge how much Microsoft's decision will affect Oracle's equipment utilization or revenue.
How Azure and OCI worked together to support Bing's AI inference
The partnership dates back to a multiyear agreement Oracle announced on November 7, 2023. According to Oracle's official announcement, Microsoft agreed to use a combination of Azure's AI infrastructure and OCI computing resources for inference processing for the AI models powering Bing's conversational search. The arrangement shared the computing load of generating AI responses in a search service between Microsoft's own cloud and Oracle's equipment. What set the deal apart was that OCI was used not for training AI models but for inference, running trained models in a live service.
On the technical side, the two clouds were linked through Oracle Interconnect for Microsoft Azure, and the setup used Azure Kubernetes Service (AKS) and other tools to manage OCI Compute resources at large scale in an integrated way. AKS is an Azure service that manages the deployment, execution, and operation of containerized applications. This allowed Microsoft to build Oracle's computing capacity into Bing's inference processing while making use of Azure's management platform. However, Oracle's announcement also included general OCI product specifications, and the GPU models and configurations described there do not necessarily represent the equipment actually deployed for Microsoft.
Comparing the 2023 announcement with the November 2026 report, here is what has come to light and what remains unknown.
| Item | Oracle announcement, Nov. 7, 2023 | Bloomberg report, Nov. 6, 2026 |
|---|---|---|
| Main use | Inference for AI models used in Bing's conversational search | Wind-down of leased AI computing resources; full set of current workloads unknown |
| Connection and management | Two clouds linked via Oracle Interconnect; OCI Compute managed in an integrated way through AKS and other tools | Destination and any new connection or management setup unknown |
| Hardware | GPU models and quantities Microsoft actually deployed cannot be identified | Older-generation NVIDIA GPUs reportedly no longer meet requirements; models unknown |
| Contract and scale | Multiyear contract | Reported non-renewal; contract value, scale of equipment involved, and wind-down completion date unknown |
Importantly, it has not been confirmed that all of the computing resources Microsoft is now winding down are the Bing-related equipment announced in 2023. Workload configurations and uses of the resources may have changed after the contract was signed, and it is not known whether the original system setup was maintained unchanged through 2026. The report therefore cannot be taken to mean that the entire Microsoft–Oracle partnership is being dissolved, nor does it indicate that Bing is being shut down or scaled back.
Demand for older GPUs and Microsoft's changing requirements
A key issue in the decision not to renew is how well Oracle's equipment matches the computing capability Microsoft needs. Bloomberg reports that older-generation NVIDIA GPUs no longer meet Microsoft's requirements, but it does not say which performance characteristics or specifications were the problem. Factors such as GPU processing power, memory capacity, power consumption, and operating costs may have played a part, but none has been confirmed as the cause. Because the GPU models are unknown, performance gaps between generations and cost-effectiveness cannot be compared in concrete numbers.
The report that the equipment no longer suits Microsoft and Oracle's statement that demand for older GPUs remains strong are not necessarily contradictory. The suitability of AI computing resources depends on the scale of the models being run, the characteristics of the workload, the response speed required, and operating conditions. GPUs that no longer fit one customer's use may still meet another customer's needs. Whether Oracle can repurpose the equipment built for Microsoft, however, also depends on its configuration, customer demand, and contract terms.
The move suggests that in procuring AI computing capacity, fit with a company's own service requirements matters as much as the number of GPUs secured. Still, it is unknown which computing platform will take over the processing once Microsoft stops using Oracle's equipment. If the scale of the wind-down, the replacement platform, and post-migration operations become clear, it will be possible to assess more concretely how far Microsoft has reorganized its externally sourced computing resources. At this point, no conclusions can be drawn about the effect on Oracle's revenue or equipment utilization, or on the search response speeds Bing users experience.
