Microsoft Corp. is winding down an arrangement to rent artificial intelligence (AI) computing capacity from rival Oracle Corp., marking a pivotal shift in the tech giant’s broader reassessment of tens of billions of dollars poured into external cloud partnerships.
In recent months, Microsoft has been turning off servers rented from Oracle after declining to renew their contract, according to a Bloomberg report, citing people familiar with the matter. The computing infrastructure, which utilizes older-generation NVIDIA Corp. graphics processing units (GPUs), no longer meets Microsoft’s evolving technical specifications for its AI workloads, the people said.
The original multi-year deal, announced in 2023 for an undisclosed sum, was struck to power an AI-assisted version of the Bing search engine.
At the time, Microsoft’s willingness to rent infrastructure from a legacy cloud rival highlighted the severe global shortage of specialized AI processors. In response to that crunch, Microsoft committed more than $80 billion across external vendors, sparking a boom for specialized neocloud providers such as CoreWeave Inc., Nebius Group, and Nscale.
Now, corporate leadership is pivoting away from costly third-party capacity. Facing internal frustration over escalating expenses, project delays, and performance bottlenecks, Microsoft is tightening oversight of data center builds and re-evaluating whether to enter further neocloud arrangements.
Evidence of that belt-tightening surfaced earlier this week when data center operator IREN disclosed delivery delays on infrastructure slated for Microsoft following requested network redesigns.
An Oracle spokesperson defended the company’s position, stating that demand for its cloud infrastructure remains robust across older and newer hardware alike.
Oracle previously noted that it successfully renewing contracts for four-year-old GPUs at a 20% premium over original rates, supported by high-profile deals with customers including OpenAI and Meta Platforms Inc. Oracle’s cloud division generated $18 billion in revenue for the fiscal year ended May 2026.
Even so, the software maker’s massive capital expenditure has raised alarms on Wall Street. Aggressive spending on data center buildouts has driven Oracle’s free cash flow into negative territory, contributing to a steep market selloff.
Oracle shares have fallen more than 50% since reaching an all-time high of $248.15 on June 1. Both Microsoft and Oracle traded flat on Friday amid broader market unease over regulatory scrutiny following recent U.S. midterm elections.
The uncoupling signals a maturing phase for the AI sector. As hyperscalers prioritize operational efficiency and self-reliance over frantic capacity grabs, suppliers relying on legacy chips or debt-fueled expansion face tougher scrutiny from the very tech giants that fueled their early growth.
