Microsoft is winding down its 2023 deal to rent AI cloud capacity from Oracle, Bloomberg reported Nov 6, 2026, via Reuters.

Microsoft declined to renew and has been switching off the rented capacity over recent months as part of a wider reassessment of multibillion dollar cloud partnerships.

The reason named is fit: Oracle servers used older generation Nvidia GPUs that no longer meet Microsoft's AI workload needs. The capacity was originally secured for AI Bing.

Size and value were not disclosed.
