OpenAI's lawyers are working with an outside firm to explore legal options against Apple, a striking deterioration of one of the most-watched partnerships in consumer AI, according to a Bloomberg report published May 14 and widely amplified on May 15, 2026. The dispute centers on the ChatGPT integration that Apple announced for Siri at WWDC 2024 and shipped in iOS 18.2 that December — a deal that OpenAI believed would mint a new subscription engine but, two years on, has produced what one OpenAI executive described as a partner that "haven't even made an honest effort."
What OpenAI is alleging
People familiar with the matter told Bloomberg that OpenAI executives expected far deeper Siri placement and broader exposure across Apple's apps. Instead, users must explicitly invoke "ChatGPT" in their prompt to be routed to OpenAI's model, and the responses surfaced inside Siri carry less context and fewer features than the standalone ChatGPT app. Per the report, Apple itself characterized the agreement as comparable in scale to its multi-billion-dollar search arrangement with Google — an expectation OpenAI internalized. Subscription conversions, the report says, have fallen well short of that yardstick.
Lawyers are reportedly weighing several escalation steps short of a full lawsuit, including a formal breach-of-contract letter. "No final decisions have been made," Bloomberg's sources said, adding that OpenAI still hopes to resolve the dispute privately.
Apple's frustrations cut the other way
The friction is not one-sided. OpenAI has been hiring away Apple talent for its own hardware program, an initiative led by former Apple design chief Jony Ive. Apple, meanwhile, has been broadening its model partners — earlier reporting this spring described iOS 27 plans to let users pick a default AI assistant and expose extension hooks for Claude, Gemini, and ChatGPT side by side. That trajectory dilutes the very exclusivity OpenAI thought it was buying when the original Siri integration shipped.
Why it matters
The Siri-ChatGPT deal was, when announced in 2024, the most prominent example of a frontier-model maker reaching hundreds of millions of devices through a platform owner. A breach-of-contract fight — even one resolved through a letter rather than a courtroom — would mark the first serious public rupture between OpenAI and a major distribution partner since its renegotiated terms with Microsoft. It also reframes how future AI labs will price platform deals: betting on subscription conversion from inside another company's assistant looks materially riskier today than it did 18 months ago.
What to watch
The immediate signal will be whether OpenAI sends a formal breach notice. A second signal is Apple's WWDC posture in June, where the company is expected to detail iOS 27's third-party AI extension framework. A more accommodating Siri integration there could defuse the fight; a clearer pivot toward Gemini or Claude as Siri co-defaults would tell OpenAI exactly where it stands. Either way, the era in which a single ChatGPT-Siri deal could anchor OpenAI's consumer distribution strategy appears to be ending.
