Microsoft is ending its revenue-sharing deal with OpenAI. In return, OpenAI can sell its products on any cloud provider it wants. Microsoft exclusivity is over.
Some ties remain. Microsoft keeps rights to OpenAI's technology through 2032, just not exclusively. OpenAI's repayment obligations to Microsoft are capped through 2030. Both companies describe the relationship as "simplified," which is corporate-speak for "the old deal was holding us back."
And it was. Anthropic's rise put real pressure on OpenAI to scale faster. Being locked into Microsoft's infrastructure created bottlenecks at exactly the wrong time. Now OpenAI can work with Oracle and other providers, colocating compute where power is available rather than where Microsoft has data centers. The company is also building custom inference chips with Broadcom and TSMC to cut its dependence on Nvidia, and pursuing nuclear energy through Sam Altman's investment in Helion Energy to power its planned Stargate supercomputer.
Microsoft stays a major shareholder and preferred partner. But the competitive landscape shifted, and the original deal terms couldn't keep up. OpenAI needed room to build. Microsoft needed to stop subsidizing a partner that was outgrowing the arrangement.
