Microsoft Winds Down Oracle AI Cloud Deal as Older Chips Lose Their Fit
Direct answer
Microsoft is winding down an arrangement to rent AI computing capacity from Oracle, Bloomberg News reported on November 6, 2026. Microsoft has been switching off the rented capacity in recent months after deciding not to renew the contract. The reason, according to people familiar with the matter, is that the servers use an older generation of Nvidia chips that no longer meet Microsoft’s needs.
What happened
The deal dates back to 2023, when Oracle announced a multi-year agreement for Microsoft to use Oracle Cloud Infrastructure to power AI features in its Bing search engine. At the time, Microsoft needed extra computing power quickly as demand for AI tools surged.
Three years on, the picture has changed. Bloomberg reported that Microsoft has been turning off the rented Oracle capacity in recent months rather than renewing it. Microsoft declined to comment on the report. Oracle said demand for its AI infrastructure remains strong, including for earlier generation GPUs, and pointed out that it was renewing contracts for four-year-old chips at a 20 percent premium to their original prices.
Oracle shares fell about 3 percent in afternoon trading on November 6 after the report. The size of the original deal was never disclosed.
The report also said the move is part of a wider review by Microsoft of billions of dollars in cloud partnerships. Bloomberg said Microsoft has committed more than 80 billion dollars to renting capacity from outside providers such as CoreWeave, Nscale and Nebius, and that costs and delays have frustrated its leadership. Reuters reported the Bloomberg story on November 6, 2026.
Why it matters for beginners
AI computing is expensive, and even the biggest technology companies rent extra capacity from others when they need it fast. When a rental deal ends, it does not mean the technology has failed. It often means the hardware is now out of date for what the customer needs, or the customer has built enough of its own capacity.
This is also a useful reminder that one company can fall sharply on a single report. Oracle shares dropped about 3 percent on the news, even though Oracle said demand for its AI infrastructure remains strong. A single stock can move fast on news like this, which is why understanding what risk in investing means matters before buying shares in one company.
It is also worth keeping this deal separate from the wider Microsoft and Oracle relationship. This was one specific rental arrangement for AI computing. It was not an announcement ending every partnership between the two companies.
What to watch next
Watch whether Microsoft signs new capacity deals with other providers or builds more of its own data centres instead. Watch Oracle’s next results for signs of how quickly it can fill the freed capacity with other customers. And watch for further reports on Microsoft’s review of its outside cloud spending, since any change there could move shares of the smaller providers involved.
FAQ
Is Microsoft ending all of its work with Oracle?
No. The report covers one specific arrangement to rent AI computing capacity for Bing. It does not say Microsoft is ending every relationship with Oracle.
Why did Oracle shares fall?
Investors reacted to the loss of a large customer for that rented capacity. Oracle shares fell about 3 percent in afternoon trading on November 6, even though Oracle said demand for its AI infrastructure remains strong.
Does this mean AI spending is slowing down?
Not necessarily. The report points to older chips no longer fitting Microsoft’s needs, not to a cut in overall AI demand. Microsoft is still spending heavily on AI, but it is reviewing where that spending goes.
