Microsoft winds down its Oracle deal to rent AI cloud capacity

Microsoft is winding down its deal to rent AI computing capacity from Oracle, Bloomberg reported on November 6, 2026, citing people familiar with the matter. Microsoft declined to renew the contract and has been switching off the rented capacity in recent months. Oracle shares fell between 3% and 4% on Friday, while Microsoft barely moved.

The news landed a day after Bloomberg reported that Microsoft is stepping back from several deals with smaller GPU cloud providers. Taken together, the two reports show the largest buyer of rented AI compute getting pickier about what it pays for.

What Bloomberg reported

According to Bloomberg, as relayed by Reuters and Investing.com, the Oracle capacity became less valuable over time. It no longer met Microsoft's specifications. The Oracle hardware ran on older generations of Nvidia chips. Bloomberg could not determine the full value of the arrangement.

Microsoft declined to comment. An Oracle spokesperson said demand for its AI infrastructure remains strong, including for earlier-generation GPUs.

Oracle has a number to back that up. In September, the company said it was renewing contracts for four-year-old GPUs at a 20% premium to the original prices. So older chips still find buyers, just not at Microsoft.

How the Microsoft and Oracle deal started

The arrangement dates to November 2023. Oracle announced then that Microsoft would use Oracle Cloud Infrastructure alongside Azure to run Bing's conversational search. Microsoft needed extra capacity for the new AI version of Bing. It reached Oracle's servers through a direct interconnect between the two clouds.

At the time, Oracle's superclusters offered up to 32,768 Nvidia A100 or 16,384 H100 GPUs. Those were the top chips of 2023. Nvidia has since shipped newer generations, and Microsoft now fills its own data centers with them.

In June 2024, Oracle, Microsoft and OpenAI also agreed to extend the Azure AI platform to Oracle's cloud for OpenAI. OpenAI later signed its own much larger contracts with Oracle for Stargate. Bloomberg's report concerns Microsoft's own rental, not those OpenAI deals.

The relationship had shown strain before. In June 2026, Business Insider reported that talks on a new lease of Oracle capacity worth more than $3 billion had collapsed. The reported sticking point was FedRAMP, a federal security certification that Oracle's public cloud lacks. Oracle called the details "inaccurate" and said Microsoft remains a customer and partner.

Part of a wider pullback on rented AI compute

The Oracle story follows a similar one from November 5. Bloomberg reported that Microsoft is pulling back from some of its deals with neoclouds, the smaller providers that rent out Nvidia GPUs. Some key Microsoft leaders have developed "a case of buyer's remorse," Bloomberg wrote, according to AI Weekly.

Microsoft has walked away from several Nscale projects, including a data center of about $3 billion at Loughton in the UK. The local grid operator said it may not be able to power the site until the early-to-mid 2030s. Microsoft also declined an option that would have more than doubled its Nscale capacity in Texas. IREN's Texas campus has run into delays after a generator fire and hardware delivery problems.

Provider	Contract with Microsoft	What changed
Oracle	Not disclosed, since 2023	Not renewed, capacity being switched off
Nscale	Up to $43.8B through 2033	Loughton projects dropped, Texas option declined
Nebius	Up to $17.4B through 2031	Named in Bloomberg's pullback report
IREN	About $9.7B through 2031	Revised timeline after delays

IREN shares fell 18% and Nebius more than 16% after the neocloud report. That came on the same day as the AI chip stocks selloff, so not all of the drop traces back to Microsoft.

Oracle had a rough week of its own. On November 4, the Financial Times reported that Oracle canceled a plan to lease about 100,000 AI chips to Tencent. US officials had raised concerns about the deal.

What Microsoft's exit means for Oracle

For Oracle, the direct hit looks small. The Bing deal was a capacity rental from 2023, and Oracle's backlog now rests largely on OpenAI's Stargate contracts. Losing one older contract matters less than the signal it sends about aging GPUs.

That signal is the real story. Oracle argues that older chips keep earning money, and its 20% renewal premium suggests some buyers agree. Microsoft is now betting the other way: it would rather run new Nvidia hardware in its own data centers than pay rent on 2023-era clusters. If other large buyers follow, the value of older GPU fleets will fall faster than cloud providers planned. That would hurt anyone who borrowed against those chips.
